When the refrigerator is closed, the unfolded turnover beam may collide with another door body to damage the refrigerator. To this problem, adopt artifical mode to close the door mostly among the prior art, the reliability is poor. It often happens that the refrigerator is damaged by improper operation.

Disclosure of Invention

The present invention is directed to solving at least one of the problems of the prior art or the related art.

To this end, a first aspect of an embodiment of the present invention provides a door assembly.

According to a second aspect of the embodiment of the invention, a refrigeration device with the door body assembly is provided.

A third aspect of the embodiments of the present invention provides a door body control method.

A fourth aspect of the embodiments of the present invention provides a door body control device.

A fifth aspect of an embodiment of the present invention provides a computer-readable storage medium.

To achieve the above object, an embodiment of a first aspect of the present invention provides a door body assembly, including: at least two door bodies; the turnover beam is arranged on one side, close to the other door body, of one door body in the two adjacent door bodies, and can rotate relative to the door bodies; the sensor group is arranged on the door bodies and used for determining the unfolding and folding state of the turnover beam and the opening and closing states of the two door bodies corresponding to the turnover beam; and the controller is electrically connected with the sensor group and can control each door body to move according to the unfolding and folding state and the opening and closing state.

The door body assembly provided by the invention comprises at least two door bodies and the turnover beam arranged on one side of the two adjacent door bodies close to the other door body, and can be used for closing the interval between the two adjacent door bodies when the door bodies are closed so as to ensure the sealing property of the closed door bodies. In addition, a sensor group is additionally arranged on the door body to monitor the unfolding and folding state of the turnover beam and the opening and closing state of the door body, and the controller controls the movement of the door body according to the feedback state of the sensor, so that the door body can be normally opened and closed without interference.

The number of the door bodies can be flexibly determined according to actual use scenes, can be two or more, but understandably, at least two door bodies in the door bodies are adjacent, on the basis, the turnover beam can be arranged on one of the two adjacent door bodies, and particularly, the turnover beam is arranged on one side, close to the other door body, of one of the two adjacent door bodies.

It can be understood that in daily use, a multi-door design is often adopted for a box body with a large front area and a high requirement on sealing performance, and the purpose of the multi-door design is to reduce the area of a single door body and improve the flexibility of equipment use. In order to ensure the sealing performance between the door bodies, the turnover beam is required to be arranged between two adjacent door bodies. When the adjacent door is closed, the turnover beam is unfolded, is arranged on one door body and can be tightly attached to the edge of the other adjacent door body after being unfolded, so that the whole door body is sealed.

Further, when the turning beam is used for closing the space between two adjacent door bodies, the turning beam is in an unfolded state, and the edges of the door bodies without the turning beam press the turning beam from outside to inside at the moment and are mutually meshed so as to realize sealing. When the previous door body is in an opening state, the turnover beam is also in an unfolding state, and at the moment, the other door body is in a closing state.

In order to avoid collision caused by improper closing sequence after two adjacent door bodies are opened, the turning beam needs to be controlled to be in a folded state, namely, the turning beam and the door body section are at a certain angle, namely, the angle between the turning beam and the door body can be vertical or any non-zero angle. In this state, no matter how the previous door body rotates, the door body can avoid the adjacent door bodies, so that the possibility of collision is reduced.

The turnover beam should have two states of unfolding and folding, and the turnover beam can be switched between the two states by rotating through connecting the turnover beam with the door body in a rotating way.

Particularly, the door body assembly further comprises a sensor group and a controller, and the controller can control the door body to move through the states of the door body and the turnover beam monitored by the sensor group. The door body can be opened or closed according to the preface on the basis of effectively guaranteeing the leakproofness of the door body through setting up upset roof beam and controller to reduce the collision that takes place between the door body, improve the security in the product use, also reduce the possibility that the striking leads to the product to damage appearing.

In addition, the door body assembly provided by the embodiment of the invention can also have the following additional technical characteristics:

in the above technical solution, the sensor group includes: the first sensor is arranged on at least one of the two adjacent door bodies corresponding to the turnover beam and can determine the unfolding and folding state of the turnover beam; the second sensor is arranged on the first door body of the two door bodies corresponding to the turnover beam and can determine the opening and closing state of the first door body; and the third sensor is arranged on the second door body of the two door bodies corresponding to the turnover beam, and can determine the opening and closing state of the second door body.

In this technical solution, the sensor group includes three sensors: the first sensor, the second sensor and the third sensor can effectively acquire the two door bodies with the turnover beams and the position states of the turnover beams under the action of the sensor group. Specifically, the first sensor can determine the folding state of the turnover beam and can be arranged on any one of the two door bodies. The second sensor is arranged on the first door body and used for determining the opening and closing state of the first door body. The third sensor is arranged on the second door body and used for determining the opening and closing state of the second door body. Therefore, the opening and closing states of the two door bodies are respectively detected according to the second sensor and the third sensor, and the whole door body assembly can be comprehensively judged to be normally closed through the unfolding and folding states of the turnover beam.

Further, the first sensor may be disposed only on the first door body, or may be disposed only on the second door body, or of course, the first sensor may be disposed on both the first door body and the second door body according to the requirement.

Among the above-mentioned technical scheme, be equipped with the magnetic part on the upset roof beam, first sensor can confirm the exhibition folding state of upset roof beam according to the magnetic part.

In the technical scheme, the magnetic part is arranged on the turnover beam, and when the folding state of the turnover beam changes, the position of the turnover beam relative to the door body also changes. Because the position of the first sensor on the door body is fixed, when the folding state of the turnover beam is changed, the magnetic field generated by the magnetic part has different effects on the first sensor, so that the intensity of the magnetic field received by the first sensor can be changed. Further, the first sensor is a magnetic field sensor capable of sensing a change in the peripheral magnetic field. Therefore, the first sensor can judge whether the overturning beam is in an unfolding state or a folding state at present by analyzing the change of the magnetic field intensity.

In the technical scheme, the turnover beam is arranged on the first door body, and the controller controls the first door body and the second door body to move according to the opening and closing state of each door body and the unfolding and folding state of the turnover beam.

In the technical scheme, the turnover beam is arranged on the first door body, and the turnover beam is unfolded and folded relative to the first door body. The two door bodies can be opened and closed independently. In order to ensure that the two door bodies are not collided when opened and closed, the controller controls the rotation of the first door body and the second door body according to the opening and closing states of the two door bodies and the folding state of the turnover beam, so that the occurrence of error collision conditions is reduced, and the damage to the door bodies is caused.

An embodiment of a second aspect of the invention provides a refrigeration apparatus comprising: the refrigerator comprises a refrigerator body, wherein an opening is formed in one side of the refrigerator body; the arbitrary door body assembly in the above-mentioned first aspect embodiment is connected with the box rotation, and the door body assembly can open and close the opening, and wherein, the door body in the door body assembly includes first door body and second door body, and the upset roof beam in the door body assembly is located on the first door body.

According to the embodiment of the refrigeration equipment, the refrigeration equipment comprises a box body and a door body assembly, and an opening is formed in one side of the box body. And at the opening position, the door body assembly is rotatably connected with the box body. The door body assembly comprises a first door body and a second door body, and the turnover beam is arranged on the first door body. When two door bodies are closed and the turnover beam is also unfolded, a closed space is formed in the box body and the door body assembly, so that leakage of cold air in the using process of the refrigeration equipment is reduced, the constant temperature environment inside the refrigeration equipment is guaranteed, and storage of food materials is facilitated.

Typically, in side by side combination refrigerators, there will often be such a design. The design structure can make the door not need to be designed to be very wide, and can save space when in use. The door body is relatively light and light, and the pressure generated on the door shaft is small.

In the technical scheme, the turning beam in the door body assembly is arranged on one side, facing the opening, of the first door body.

In the technical scheme, the turnover beam is positioned on one side, close to the box body, of the door body. When two adjacent door bodies in the door body assembly are closed, the unfolding state of the turnover beam is parallel to the two door bodies, and the folding state of the turnover beam is turned towards the direction in the box and forms a certain angle with the door body where the turnover beam is located, so that the turnover beam is prevented from interfering with the first door body when turned outwards.

It can be understood that the rotation angle of the turning beam can be between the angle of the unfolding state and the angle of the folding state, and when the turning beam is in the folding state, if the turning beam and the first door body form 90 degrees, the rotation angle range of the turning beam is 0-90 degrees.

An embodiment of a third aspect of the present invention provides a door body control method for a refrigeration apparatus, including: acquiring the unfolding and folding state of a turnover beam in refrigeration equipment and the opening and closing states of two door bodies corresponding to the turnover beam; and controlling the movement of the two door bodies according to the opening and closing state and the unfolding and folding state of each door body.

According to the embodiment of the door body control method provided by the invention, whether the door bodies are interfered or not can be judged according to the folding state of the turnover beam and the opening and closing state of each controlled door body, so that the door bodies are moved according to the preset door closing control steps, the door bodies are prevented from colliding with each other and being damaged when the door bodies are closed, and the door bodies can be ensured to be closed in a correct mode.

It needs to be emphasized that, because the unfolding and folding state of the turnover beam and the opening state of the door body in which the turnover beam is located have a certain corresponding relationship, whether the current door body fails or not can be accurately obtained by acquiring the unfolding and folding state, and whether interference occurs or not when the door is closed.

Among the above-mentioned technical scheme, according to the removal of the two door bodies of the open-close state of every door body and the state control of folding, specifically include: when the overturning beam is in an unfolding state, if the first door body is opened, a door closing control step is obtained, and the first door body and the second door body are controlled to be opened and closed according to the door closing control step; when the turning beam is in a folded state, if the first door body is closed, it is determined that the refrigeration equipment breaks down, wherein the turning beam is in an unfolded state when being parallel to the first door body, and the turning beam is in a folded state when being at a non-zero angle with the first door body.

In this technical scheme, when the control door body removes, whether mainly can confirm to break down according to the open and close state of the first door body that the exhibition of upset roof beam was put and is located, what need explain in advance, when being parallel with the first door body, the upset roof beam is the expansion state, and when being nonzero angle between with the first door body, the upset roof beam then is fold condition. When the door body is closed, the door body control method determines the corresponding door closing control step according to the turning beam and the current opening and closing state of each door body.

Specifically, the turnover beam is in an unfolded state, and the first door body is in an opened state. In this case, during the door closing process, the turnover beam may collide with the second door body to damage the door bodies, and a door closing control step must be taken to control the closing of the first door body and the second door body. Certainly, in the closing process, the second door body may have two states of opening and closing, so that the current state condition of the second door body needs to be processed when the door closing step is executed, and the correct closing of the first door body and the second door body is ensured.

And when the first door body is in a closed state, no matter the turnover beam is unfolded or folded, the turnover beam cannot be damaged due to collision with the second door body. But for tightness requirements the turndown beam should be in the unfolded state at this time. If the first door body is closed and the turnover beam is folded, no matter the second door body is opened or closed, the door body control method can judge that the current equipment has a fault, the detection of a sensor may be in a problem, or the turnover beam cannot be normally closed, and in any case, the turnover beam belongs to the refrigeration equipment and breaks down, and at the moment, fault information can be sent to a target terminal associated with the refrigeration equipment in advance or an alarm can be directly sent out to remind a user.

In addition to this, there are also situations that: the turnover beam is unfolded, and the first door body is closed. At the moment, the first door body is in a closed state, the overturning beam is arranged on one side of the upper box body of the first door body, and the situation that the overturning beam collides with the second door body when the door is closed does not exist, so that the door can be normally closed when the second door body is closed, and other auxiliary steps are not needed.

Certainly, when the turnover beam is folded and the first door body is opened, because the turnover beam is already in a folded state, when the first door body is closed, the first door body does not collide with the second door body, and therefore the control method does not need to be controlled no matter the second door body is opened or closed.

In the above technical solution, the door closing control step specifically includes: controlling the second door body to close; controlling the second door body to be opened within the opening time; controlling the first door body to close; and controlling the second door body to close.

In the technical scheme, under the condition that the door needs to be closed by adopting a door closing control step, the second door body without the turnover beam is closed firstly in the process, and because the motion track of the second door body is not influenced by the turnover beam if the second door body does not exist, the second door body is closed firstly and then opened, so that the second door body is opened firstly no matter the initial state of the second door body is a closed state or an opened state, the first door body provided with the turnover beam is controlled to be closed after the second door body is opened, the first door body is ensured to be closed in the state that the second door body is opened, the possibility of interference between the turnover beam and the second door body is reduced, the door closing control of the second door body is realized after the first door body is closed, and the whole automatic door closing process is completed.

In the above technical solution, the door body control method, after determining that the refrigeration equipment has a fault, further includes: and sending fault information to a target terminal associated with the refrigeration equipment.

In the technical scheme, after the door body control method determines that the refrigeration equipment has a fault, fault information is sent out to remind a user and inform related equipment maintenance personnel. Specifically, a digital tube code display can be additionally arranged on the refrigeration equipment to display fault information and send out sound alarm to prompt equipment maintenance personnel to maintain in time. And after the equipment maintenance personnel see the fault information, corresponding treatment measures are taken. This method is more applicable to industrial environment equipment and requires specialized equipment maintenance personnel. Due to the popularization of the LED screen, the fault information can be sent in a mode of displaying characters, images and the like on the LED screen.

In addition, along with the popularization of thing networking and smart machine, can pass through the long-range propelling movement fault information of thing networking or directly upload the server through the APP, in time remind maintainer to carry out equipment maintenance.

In the above technical solution, further comprising: and when the turning beam is in an unfolding state, if the first door body is opened, displaying prompt information corresponding to the door closing control step.

In the technical scheme, when the turnover beam is in an unfolded state, if the first door body is opened, the door body control method can adopt the door body control step to close the door. When the door body control step is automatically carried out, the equipment simultaneously shows the current step of door closing control to the user, so that the user can clearly know the current process of the door closing control step, and the progress can be conveniently known in real time. Under specific conditions, if mechanical equipment for automatically controlling the door to be opened and closed fails and needs to be manually closed, the door body control method can guide a user to correctly close the door according to the door closing step by displaying prompt information.

The presentation of the prompt message can be realized in an audio or video mode.

An embodiment of a fourth aspect of the present invention provides a door body control device, including a processor and a memory, where the processor is configured to implement the steps of any one of the door body control methods in the third aspect of the present invention when executing a computer program stored in the memory.

According to an embodiment of the door control device of the present invention, the door control device includes a processor and a memory, and since the processor can execute a computer program or an instruction stored in the memory and implement any one of the door control methods of the first aspect when executing the computer program or the instruction, the door control device of the present invention has all the beneficial effects of the door control method in any one of the above technical solutions, and details are not repeated herein.

Detailed Description

In order that the above objects, features and advantages of the embodiments of the present invention can be more clearly understood, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, embodiments of the present invention may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.

Door assemblies, refrigeration equipment, door control methods, devices, and storage media provided according to some embodiments of the present invention are described below with reference to fig. 1 to 16.

The first embodiment is as follows:

an embodiment of the present invention provides a door assembly, as shown in fig. 1, comprising: at least two door bodies 10; a turnover beam 106, a sensor group 70 and a controller 20. When the door body 10 with the turnover beam 106 is closed, the turnover beam 106 may collide with the door body 10. The controller 20 of the invention collects the folding state information of the turnover beam 106 and the opening and closing state of the door bodies 10 through the sensor group 70, controls each door body 10 to move, and realizes the collision-free automatic closing of a plurality of door bodies.

As shown in fig. 2, the door body assembly includes two door bodies: a first door body 102 and a second door body 104. As shown in fig. 3, in practical application, the door assembly may include three doors: the first door body 102, the second door body 104 and the third door body 208. According to actual needs, the door body assembly can even contain more door bodies. The multiple door bodies can improve the performance of the box body equipment with larger frontal area. However, because of the problem of closeness of the door bodies that are split, a turndown beam 106 is typically added between the two door bodies. The turning beam 106 is a column with the same height as the door, is arranged on a door body and can rotate within a certain angle range. After the adjacent door bodies are closed, the turnover beam 106 is unfolded and then closely attached to the edge of the other adjacent door body, as shown in fig. 4, so as to seal the whole door body.

The turning beam 106 has two normal working states of unfolding and folding, wherein the unfolded state is shown in fig. 5, the turning beam 106 is parallel to the door body, and the folded state is shown in fig. 6, the turning beam 106 is perpendicular to the door body.

In another embodiment, the folded state may be set to other angles as long as it is achieved that the door does not collide with the adjacent door body when the door is closed.

In the actual use process, as shown in fig. 7, the turnover beam 106 and the adjacent door body often collide with each other to damage the equipment, so that in this embodiment, a method is provided in which the states of the turnover beam 106 and the door body are measured by setting a sensor group, and the controller controls the door body to be closed according to the setting steps, so as to avoid the collision between the door body and the turnover beam 106 when the door is closed.

The sensor for measuring the opening and closing state of the door body is arranged on the door body. The sensor can adopt various modes, such as judge the state of door through measuring circuit break-make, judge laminating distance etc. of door and door frame through the magnetic induction mode. The sensor for measuring the state of the turnover beam 106 is also arranged on the door body, and various and common modes can be adopted in a magnetic induction mode.

The sensor digitizes the measured specific signal, the door body only has two states of opening and closing, the turnover beam 106 only has two states of unfolding and folding, and no intermediate state exists.

After the sensor group measures the states of the door body and the turnover beam 106, the state information is sent to the controller. And the controller sends corresponding actions to the actuating mechanism according to a preset program to control the movement of the door body. And after the door body is closed, the door closing action is finished.

Example two:

as shown in fig. 8, the present embodiment provides a sensor group mounted to a door assembly. The door body assembly in this embodiment includes two door bodies that are split, that is, a first door body 102 and a second door body 104, and a turning beam 106 is mounted on the first door body 102. The sensor suite enables measurement of the condition of the door body assembly and the tilt beam 106. The first sensor 702 measures the folding state of the turnover beam 106, the second sensor 704 measures the opening/closing state of the first door 102, and the third sensor 706 measures the opening/closing state of the second door 104.

In a particular embodiment, the overturning beam 106 can rotate within a certain range, but typically only two angles are normal in operation, i.e. a minimum angle and a maximum angle of rotation. The first sensor 702 is used to measure the unfolding and folding state of the turning beam 106, and it can be determined that the turning beam 106 is definitely not in one of the working states as long as the turning beam 106 is detected to be in the other working state. Thus, the first sensor 702 is normally disposed at a position near a certain normal position of operation from the overturning beam 106. This embodiment selects a position close to the folded state of the flipping beam 106, such as the position of the first sensor 702 in fig. 8. In practical applications, if the first sensor 702 adopts other measurement methods, it is a feasible method as long as the two working states of the turning beam 106 can be clearly distinguished, and details are not described herein.

In this embodiment, the second sensor 704 is used for measuring the open/close state of the first door 102, and the third sensor 706 is used for measuring the open/close state of the second door 104. The opening and closing states of the two door bodies are the same in design, the second sensor 704 and the third sensor 706 can be realized by adopting sensors with the same principle, and of course, the sensors with different principles can be selected according to the actual use environment and the structural limitation of the product.

When the door body assembly is used for a household refrigerator, when the door body and the door frame are close to a certain angle, the door body can be completely closed by the aid of magnetic attraction. If the door body is not closed at the moment, the door body can be bounced to a certain angle by the device so as to remind a user to close the door body again. Therefore, in practice, the door body can be determined to be in the closed state as long as the angle between the door body and the door frame is determined to be smaller than a certain angle. In addition, the open state is assumed. For the sensor, the door body has only two working states. There is no transition state or third state.

A plurality of sensors capable of achieving the functions are provided, for example, a common household refrigerator is provided, the light in the refrigerator body is on when the door body is opened through one key on the door edge, and the light is turned off after the door body is closed. In industrial equipment or scientific research equipment, the performance requirement on the equipment is high, and various modes such as a magnetic induction sensor, an electronic switch and the like can be adopted.

The second sensor 704 and the third sensor 706 in this embodiment have a common feature that both are disposed on the door body, as shown in fig. 8.

Example three:

as shown in fig. 8, a magnetic member 708 is provided on the rocker beam 106, and a first sensor 702 is provided on the first door body 102. The first sensor 702 in this embodiment is a magnetic induction sensor, such as a hall sensor. As shown in fig. 8, when the turning beam 106 is folded to an angle close to perpendicular to the first door body 102, the first sensor 702 is close to the magnetic member 708 of the turning beam 106, and the magnetic field around the first sensor 702 is increased, so that it can be determined that the turning beam 106 is in the folded state. When the flipping beam 106 is at a distance from the first sensor 702, the apparatus will automatically adjust the flipping beam 106 to the unfolded state, at which time the magnetic field strength is reduced and the first sensor 702 assumes that the flipping beam 106 is in the unfolded state. Therefore, the first sensor 702 can determine that the turnover beam 106 is in the folded state as long as it detects a strong magnetic field signal; otherwise the flip beam 106 is in the unfolded state.

Example four

As shown in fig. 9, the present embodiment provides a housing 108. An opening is formed in one side of the box body 108, a door body assembly is mounted on the opening, and the door body assembly is rotatably connected with the box body 108. The door body assembly in this embodiment has two doors, including a first door body 102 and a second door body 104. The first door body 102 is provided with a turnover beam 106. The design structure of the box body 108 has good sealing performance, and can well isolate the environment inside and outside the box body 108 when the door body assembly is closed, so that the design structure is particularly suitable for the design of large-scale constant temperature equipment, especially large-scale refrigeration equipment.

EXAMPLE five

As shown in fig. 9, the present embodiment provides a housing 108. The turning beam 106 of the box 108 is arranged on the door body, and one side in the box 108 can rotate inwards. The function of the turnover beam 106 is to close the gap between two door bodies when the door bodies are closed. Generally, the shape of the turnover beam 106 is a flat column, the height of the turnover beam is the same as the inner height of the door bodies, and the width of the turnover beam is slightly wider than the width of the interval between the two door bodies when the door bodies are closed. In a normal operating state, the turnover beam 106 should be in an unfolded state, parallel to the two door bodies, and closely attached to the two door bodies to close the gap between the two door bodies. When the first door body 102 is opened, the turnover beam 106 can rotate. As shown in fig. 10, it is apparent that the tilt beam 106 is rotated inward to effectively avoid collision with the second door body 104.

EXAMPLE six

In an embodiment of the present invention, as shown in fig. 11, a door body control method includes: step S1002, the controller acquires the unfolding and folding state of a turnover beam and the opening and closing state of a door body in the door body assembly through a sensor group; in step S1004, the controller controls the movement of the door body according to the obtained status information.

In this embodiment, the controller acquires the unfolding and folding state of the turnover beam and the opening and closing states of the two door bodies through the sensor group as control input signals of the controller. The controller generates a control command according to a preset control method and sends the control command to the executing mechanism. The actuating mechanism moves the door body, and finally the door body reaches a preset state. And finishing the door closing process of the door body.

EXAMPLE seven

In one embodiment of the invention, the door body control method generates corresponding control commands according to a preset control method according to the state of the turnover beam and the states of the two door bodies as input signals. As shown in fig. 12.

The door body control method comprises the following steps: step S1102, a controller acquires the current working state of the turnover beam; and step S1104, determining whether the overturning beam is in an unfolded state. If the current state of the turnover beam is unfolding, the controller jumps to step S1106, and the controller acquires the working state of the first door body. In step S1108, the controller determines whether the first door is in an open state. If the first door body is in an open state, the controller skips to step S1110 to send a door closing command to the executing mechanism to execute a door closing action; if the first door body is in the closed state in step S1108, the controller determines that the current door body assembly does not collide with the second door body, and skips to step S1114 without performing door closing control.

Returning to the step S1104, if the controller determines that the turning beam is in the folded state, that is, not in the unfolded state, the controller skips to the step S1118, and the controller obtains the working state of the first door body. Step S1120, the controller determines whether the first door body is in an open state, and if the first door body is determined to be in the open state, the controller jumps to step S1122 without performing door closing control; if the first door body is judged to be in the closed state at present in step S1120, the controller considers that the equipment is in the fault state at present, and then the step S1126 is skipped to for fault alarm processing.

Similarly, the controller can also acquire the states of the turnover beam and the first door body at the same time to control the closing of the door body. As shown in fig. 13. Step S1202, the controller obtains the working states of the turnover beam and the first door body, and judges the states of the turnover beam and the first door body according to the step S1206, wherein the states are as follows: unfolding the turnover beam, opening the first door body, and jumping to step S1110 by the controller to control the first door body and the second door body to be closed; the state is as follows: the overturning beam is unfolded, the first door body is closed, the controller jumps to step S1114, and the opening and closing of the door body are not controlled; the state is as follows: the turning beam is folded, the first door body is opened, the controller jumps to the step S1122, and the opening and the closing of the door body are not controlled; the state is as follows: the overturning beam is folded, the first door body is closed, the controller skips to the step S1126, and the controller gives a fault alarm.

Example eight

In one embodiment of the invention, the controller invokes the door closing control step of the controller when determining that the door body assembly is in the deployed state in accordance with the tilt beam and that the first door body is in the open state and is ready to be closed. As shown in fig. 14, the door closing control step includes: step S1302, controlling the second door body to close; step S1304, controlling the second door body to open within a preset opening time; step 1306, controlling the first door body to close; step S1308, the second door body is controlled to close.

It can be understood that, in the door closing control step, a door closing operation is performed first no matter whether the second door body is in a closed state or not, so as to ensure that the second door body is closed. After the closing action of the second door body is completed, the door closing control step opens the second door body within the opening time. In the present embodiment, the on time is set to 2 seconds. In practical application, the opening time is set according to the size of the equipment and the size of the door body. After the second door body is opened, the controller controls the first door body to close the door. And after the first door body is closed, closing the second door body. It is clear that by such an operation it is ensured that the tilting beam does not collide with the second door body. Thus, this operation can be done automatically.

Further, in certain cases, the door closing operation needs to be performed manually. At the moment, the door body control method can timely give out reminding or operation guidance to a person who closes the door, so that misoperation of the person is avoided, the person is guided to correctly complete door closing action, and the door body is prevented from being damaged by misoperation of a person unfamiliar with equipment.

Example nine

On the basis of the seventh embodiment, step S1126 issues failure information to the target terminal associated with the refrigeration apparatus. Generally speaking, the sent fault information should be sent to the user in time to remind the user that the equipment has failed, and the equipment failure needs to be eliminated as soon as possible. At the same time, the user should also be notified of what failure has occurred at all times, and the reason for the possible failure. If the equipment is industrial equipment, professional equipment maintenance personnel are usually provided, and the function can be realized by adopting sound alarm, nixie tubes or LED screen prompt for equipment notification. If the equipment is connected with the network, fault information can be sent through the network, and related equipment maintenance personnel can be informed in time. For a family user, such as a household refrigerator, due to the popularization of the wireless Internet of things, a message can be pushed to a user mobile phone APP through a wireless network, so that the user can timely handle faults.
