Description

Technical Field

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

[0002] At present, due to users' demand for multi-functional display of refrigeration equipment, a display screen is generally installed on the door body, and the main control unit for controlling the display screen is generally installed on the box body. Therefore, it is necessary to install cables at the hinges where the box body and the door body cooperate. The more functions the refrigeration equipment has, the more wiring harnesses there are, and the larger the door body space required to accommodate the wiring harnesses. It has been proposed to use a contactless connection between the display screen and the main control unit to achieve an ultra-thin door body, but there is a possibility of connection failure in contactless connection.

[0003] In view of this, it is necessary to design a new control method for refrigeration equipment to solve one of the above problems. Summary of the invention

[0004] The present invention provides a control method for refrigeration equipment to solve one of the above problems.

[0005] In order to achieve the above object, the technical solution provided by the present invention is as follows:

[0006] A control method for a refrigeration device, wherein the refrigeration device comprises: a box body, a door body, and a signal transmission component, wherein the signal transmission component comprises a light-emitting element and a photoresistor, wherein one of the light-emitting element and the photoresistor is arranged on the box body, and the other is arranged on the door body; the refrigeration device further comprises a self-test device, and a main control device connecting the signal transmission component and the self-test device, wherein the self-test device comprises a photovoltaic panel, a power storage module electrically connected to the photovoltaic panel, and a current detection unit electrically connected to the photovoltaic panel, wherein the photovoltaic panel and the light-emitting element are arranged at intervals; and the main control device comprises a power supply unit for supplying power to the light-emitting element;

[0007] The control method comprises:

[0008] Determine whether the refrigeration equipment needs self-inspection;

[0009] If self-test is required, a self-test procedure is started, the self-test procedure comprising: using the power storage module to supply power to the light-emitting element for a first preset time period;

[0010] Whether the signal transmission of the refrigeration equipment is normal is determined according to the display result of the current detection unit.

[0011] Further, determining whether the refrigeration equipment needs self-inspection includes:

[0012] The brightness of the light emitting element is adjusted to a first preset brightness L1, and the current of the current detection unit is obtained as I1, and the difference between I1 and the first preset current I1' is Δ1;

[0013] Then, the brightness of the light-emitting element is adjusted to a second preset brightness L2, the current of the current detection unit is obtained as I2, and a difference Δ2 between I2 and the second preset current I2' is calculated;

[0014] If the ratio of the absolute value of Δ1 to I1' is not less than 30% or the ratio of the absolute value of Δ2 to I2' is not less than 30%, it is determined that the refrigeration equipment needs self-inspection.

[0015] Further, determining whether the refrigeration equipment needs self-inspection includes:

[0016] Adjust the brightness of the light-emitting element to a first preset brightness L1, and obtain the current of the current detection unit as I1;

[0017] Then, the brightness of the light-emitting element is adjusted to a second preset brightness L2, and the current of the current detection unit is obtained as I2;

[0018] The difference Δ3 between I1 and I2 is compared with the third preset current I3. If the ratio of the absolute value of Δ3 to I3 is not less than 30%, it is determined that the refrigeration equipment needs self-inspection.

[0019] Furthermore, before adjusting the brightness of the light-emitting component, it is determined whether the refrigeration equipment needs a pre-self-test. If so, the pre-self-test program is started for the refrigeration equipment. If not, the brightness of the light-emitting component is controlled and adjusted.

[0020] Further, determining whether the refrigeration equipment needs a pre-self-test includes:

[0021] Obtaining the output current I4 of the photovoltaic panel when the refrigeration equipment is working normally, and comparing I4 with a fourth preset current I4';

[0022] If I4 is less than I4', the pre-self-test procedure of the refrigeration equipment is started;

[0023] If I4 is not less than I4', the brightness of the light-emitting element is directly adjusted.

[0024] Furthermore, the pre-self-test procedure of the refrigeration equipment includes:

[0025] controlling the power supply unit to increase the brightness of the light emitting element for a second preset time period,

[0026] If the current of the current detection unit increases accordingly, it is pre-determined that the light-emitting element is normal, and then the self-test procedure is entered;

[0027] If the current of the current detection unit does not change, it is determined that the performance of the light-emitting panel is weakened, and the photovoltaic panel is replaced.

[0028] Furthermore, the self-check procedure of the refrigeration equipment also includes:

[0029] After the power storage module is used to supply power to the light-emitting element, the current I5 of the current detection unit and the fifth preset current I5' are measured. If I5 is not greater than I5', it is determined that the performance of the light-emitting element is weakened.

[0030] Furthermore, if the output current of the photovoltaic panel is not obtained, it is determined that the refrigeration equipment needs self-inspection.

[0031] Furthermore, during the execution of the self-test procedure, if the current detection unit detects current, it is determined that the power supply unit of the light-emitting element cannot work normally; if the current detection unit does not detect current, it is determined that the light-emitting element cannot work normally.

[0032] Furthermore, the self-test procedure of the refrigeration equipment also includes controlling the power supply unit to supply power to the light-emitting component for a second time before using the power storage module to supply power to the light-emitting component. If the current detection unit does not detect the output current of the photovoltaic panel, the power storage module is used to supply power to the light-emitting component.

[0033] Compared with the prior art, the beneficial effect of the present invention is that the control method of the refrigeration equipment of the present invention detects potential fault hazards of the signal transmission component by executing a self-check program, avoids the photoresistor receiving an erroneous signal and issuing an erroneous instruction, and improves the user experience.

DETAILED DESCRIPTION

[0040] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present invention.

[0041] It should be noted that the terms "upper" and "lower" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the auxiliary figures, and are only for the convenience of simplifying the description of the present invention, rather than indicating or implying that the device referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention. Specifically, in the present invention, the user's operating surface is the front, the direction toward the ground is the bottom, and conversely, the direction away from the ground is the upper, and other descriptions indicating directions are defined based on "upper" and "lower".

[0042] In various drawings of the present invention, for the convenience of illustration, some sizes of structures or parts are exaggerated relative to other structural parts, and therefore, they are only used to illustrate the basic structure of the subject matter of the present invention.

[0043] The control method of the refrigeration equipment of the present invention is implemented based on the structure of the refrigeration equipment. Figures 1 to 3 As shown, the refrigeration equipment includes: a box body 10, a door body 20, and a signal transmission component, wherein the signal transmission component includes a light-emitting component 31 and a photoresistor 32, wherein one of the light-emitting component 31 and the photoresistor 32 is arranged on the box body 10, and the other is arranged on the door body 20; the refrigeration equipment also includes a self-test device 40, and a main control device (not shown) connecting the signal transmission component and the self-test device 41, wherein the self-test device 40 includes a photovoltaic panel 41, a power storage module 42 electrically connected to the photovoltaic panel 41, and a current detection unit (not shown) electrically connected to the photovoltaic panel 41, wherein the photovoltaic panel 41 is spaced apart from the light-emitting component 31; and the main control device includes a power supply unit (not shown) for supplying power to the light-emitting component 31. The present invention is described in detail by taking the light-emitting component 31 being arranged on the door body 20 and the photoresistor 31 being arranged on the box body 10 as an example.

[0044] Specifically, a hinge plate 11 and a hinge box 12 matched with the hinge plate 11 are provided on the top wall of the box body 10, and the photoresistor 32 is located in the hinge box 12. The hinge plate 11 is provided with a through hole 111 penetrating along its thickness.

[0045] The upper end of the door body 20 is provided with a hinge shaft 21, and the hinge shaft 21 is pivotally connected with the hinge plate to open or close the door body. The hinge shaft 21 passes through the through hole 111 and its upper end extends into the hinge box 12.

[0046] The hinge shaft 21 has an upwardly open receiving cavity 211 , the light emitting member 31 is located in the receiving cavity 211 , and the photoresistor 32 is located above the hinge shaft 21 in the hinge box 12 , that is, the photoresistor 32 is located directly above the light emitting member 31 .

[0047] The hinge shaft 21 is made of a VC liquid cooling plate, which dissipates heat quickly, and the light-emitting element 31 provides a working space with a relatively safe temperature.

[0048] The signal transmission component also includes a condenser 36 located between the light-emitting component 31 and the photoresistor 32. The condenser 36 is located in the receiving cavity 211 to focus the light emitted by the light-emitting component 31 and then irradiate it onto the photoresistor 32, thereby improving the degree to which the photoresistor 32 senses light, thereby improving the sensitivity of the photoresistor 32 to sensing light.

[0049] The main control device is electrically and communicatively connected to the light-emitting component 31 and the photoresistor 32 respectively. The refrigeration device also includes a first cable group 33 arranged in the hinge box to connect the photoresistor 32 and the main control device, and a second cable group 34 arranged in the receiving cavity 211 to connect the light-emitting component 31 and the display unit.

[0050] The self-checking device 40 is used to power the light-emitting component 31 when performing a self-check on the signal transmission of the light-emitting component 31. Specifically, the self-checking device 40 includes a photovoltaic panel 41, a power storage module 42 electrically connected to the photovoltaic panel 41, and a cable 43 electrically connecting the power storage module 42 and the light-emitting component 31. When the refrigeration equipment is working normally, the photovoltaic panel 41 receives the light from the light-emitting component 31, converts the light energy into electrical energy, and then the electrical energy is stored in the power storage module 42. When the power storage module 42 is needed to power the light-emitting component 31, the power supply unit of the main control device to the light-emitting component 31 is disconnected, and the power storage module 42 is controlled to power the light-emitting component 31, so as to determine whether the signal transmission component fails.

[0051] The photovoltaic panel 41 is located above the hinge shaft 21, and the front of the photovoltaic panel 41 is arranged toward the light-emitting component 31. The photovoltaic panel 41 of the present invention does not limit the specific type of the photovoltaic panel 41, including but not limited to conventional silicon-based photovoltaic panels and flexible thin-film photovoltaic panels. Preferably, the photovoltaic panel 41 and the light-emitting component 31 are arranged at intervals along the axial direction of the hinge shaft 21. When the photovoltaic panel 41 is a flexible thin-film photovoltaic panel, the photovoltaic panel 41 can also be located on the inner wall of the receiving cavity 211 along the radial direction of the hinge shaft 21, so that the photovoltaic panel 41 can also receive the light energy of the light-emitting component 31 and convert it into electrical energy.

[0052] The photovoltaic panel 41 and the photoresistor 32 are arranged side by side along the radial direction of the hinge shaft 21, so that the photoresistor 32 and the photovoltaic panel 41 do not block each other and can simultaneously receive the light signal of the light emitting element 31. Preferably, the photovoltaic panel 41 and the photoresistor 32 are adjacent and arranged side by side.

[0053] The power storage module 42 is located on the side of the photovoltaic panel 41 away from the light-emitting component 31. On the one hand, it will not block the light of the light-emitting component 31. On the other hand, it is arranged adjacent to the photovoltaic panel 41 to reduce the use of cables 43 and reduce the power loss caused by the current transmitted by the cables 43.

[0054] In this embodiment, the power storage module 42 is located above the photovoltaic panel 41 and the photoresistor 32, that is, the power storage module 42 is located in the hinge box 12, and the refrigeration equipment also includes a third cable group 35 connecting the power storage module 42 and the main control device to realize the control operation of the main control device on the power storage module 42.

[0055] Furthermore, since the light-emitting element 31 is inside the door body 20, the brightness of the light-emitting element 31 cannot be observed during normal operation, and the self-test device 40 further includes a current detection module (not shown) electrically connected to the photovoltaic panel 41 to detect the current of the photovoltaic panel 41. The photoelectric conversion of the photovoltaic panel 41 is characterized by observing the reading of the current detection module, that is, to characterize the brightness of the light-emitting element 31. The current detection module is communicatively connected to the main control device, and can monitor the current converted by the photovoltaic panel 41 in real time.

[0056] Furthermore, if Figure 5 As shown, the inner wall of the hinge shaft 21 is provided with a groove 211 extending along its axial direction, and the cable 43 is located in the groove 211. Preferably, the groove 211 is connected to the accommodating cavity 211 to fix the cable 43. At the same time, it reduces the radial space occupied by the hinge shaft 21, thereby reducing the space occupied by the hinge shaft 21 in the door body 20, which can effectively reduce the thickness of the door body 20.

[0057] The control method of the refrigeration equipment includes: determining whether the refrigeration equipment needs self-inspection, and if so, starting the self-inspection program; if not, the refrigeration equipment continues to work normally; wherein the self-inspection program includes: using the power storage module 42 to power the light-emitting element 31 and continuing for a first preset time; and determining whether the signal transmission of the refrigeration equipment is normal according to the display result of the current detection unit.

[0058] Among them, one way to determine whether the refrigeration equipment needs self-inspection includes: adjusting the brightness of the light-emitting element 31 to the first preset brightness L1, obtaining the current of the current detection unit as I1, and the difference Δ1 between I1 and the first preset current I1'; then adjusting the brightness of the light-emitting element 31 to the second preset brightness L2, obtaining the current of the current detection unit as I2, and calculating the difference Δ2 between I2 and the second preset current I2'; if the ratio of the absolute value of Δ1 to I1' is not less than 30% or the ratio of the absolute value of Δ2 to I2' is not less than 30%, it is determined that the refrigeration equipment needs self-inspection. This embodiment is to determine whether the refrigeration equipment needs self-inspection at a fixed time.

[0059] Under normal circumstances, the power supply unit of the refrigeration equipment controls the brightness of the light-emitting element 31 differently under different instructions. The above method of determining whether self-test is needed is to check whether the light-emitting element 31 changes its brightness according to the instruction after receiving the instruction to adjust the brightness from the power supply unit. Since the light emitted by the light-emitting element 31 under different light intensities is absorbed by the photovoltaic panel 41 and the converted electric energy corresponds to the preset current value, the refrigeration equipment also needs to perform self-test when any of the brightness adjustment instructions do not correspond.

[0060] In the above process of determining whether self-test is needed, the difference Δ3 between I1 and I2 can also be compared with the third preset current I3. If the ratio of the absolute value of Δ3 to I3 is not less than 30%, it is determined that the refrigeration equipment needs self-test. It can also be checked whether the brightness of the light-emitting component 31 corresponds to the preset situation under the instructions of different brightness of the power supply unit.

[0061] In order to check whether the self-test device 40 is normal, that is, whether the photovoltaic panel 41 and the power storage unit 41 are normal, before adjusting the brightness of the above-mentioned light-emitting component 31, it is determined whether the refrigeration equipment needs a pre-self-test. If a pre-self-test is required, the pre-self-test program is started for the refrigeration equipment. If a pre-self-test is not required, the brightness of the light-emitting component 31 is controlled and adjusted.

[0062] Among them, judging whether the refrigeration equipment needs a pre-self-test includes: obtaining the output current I4 of the photovoltaic panel when the refrigeration equipment is working normally, and comparing I4 with a fourth preset current I4'; if I4 is less than I4', starting the pre-self-test program of the refrigeration equipment; if I4 is not less than I4', directly adjusting the brightness of the light-emitting component 31 to judge whether the refrigeration equipment needs a self-test.

[0063] Specifically, the pre-self-test procedure of the refrigeration equipment includes: controlling the power supply unit to increase the brightness of the light-emitting component 31 and continuing it for a second preset time period. If the current of the current detection unit increases accordingly, it is pre-determined that the light-emitting component 31 is normal, and then the self-test procedure is entered; if the current of the current detection unit does not change, it is determined that the performance of the photovoltaic panel 41 is weakened, and the refrigeration equipment issues an alarm instruction based on the result of the determination, reminding the user to repair or replace the photovoltaic panel 41.

[0064] In this embodiment, the self-test procedure of the refrigeration equipment also includes: after the power storage module 42 is used to power the light-emitting component 31, the current I5 of the current detection unit and the fifth preset current I5' are measured. If I5 is not greater than I5', it is determined that the performance of the light-emitting component 31 is weakened, and the refrigeration equipment issues an alarm according to the instruction to remind the user to replace or repair it.

[0065] Another way to determine whether the refrigeration equipment needs self-inspection is: if the output current of the photovoltaic panel 41 is not obtained, it is determined that the refrigeration equipment needs self-inspection, and then the self-inspection program is started, that is, the refrigeration equipment fails and the self-inspection program is passively started.

[0066] During the execution of the self-test procedure, the power storage unit 42 is used to power the light-emitting component for a first preset time period. If the current detection unit detects current, it is determined that the power supply unit of the light-emitting component 31 cannot work normally. If the current detection unit does not detect current, it is determined that the light-emitting component 31 cannot work normally, and the refrigeration equipment issues a corresponding command alarm to remind the user to perform maintenance.

[0067] In the above two self-checking procedures, the self-checking procedure of the refrigeration equipment also includes, before the power storage module 42 is used to power the light-emitting element 31, controlling the power supply unit to supply power to the light-emitting element 31 for a second time, and if the current detection unit does not detect the output current of the photovoltaic panel 41, using the power storage module 42 to supply power to the light-emitting element 31. That is, it is used to eliminate the contact problem between the light-emitting element 31 and the power supply unit.

[0068] Furthermore, in the self-test procedure and pre-self-test procedure, the power supply unit supplies power to the light emitting element 31 for a first preset time period, so that the light emitting panel 41 can stably absorb light and convert it into electrical energy, thereby improving the accuracy of the current detection unit.

[0069] It is understandable that each time the light emitting element 31 is controlled to emit light, the current may be repeatedly obtained multiple times, and the current obtained multiple times may be compared with the preset current to eliminate errors.

[0070] In summary, the control method of the refrigeration equipment of the present invention detects potential fault hazards of the signal transmission component by executing a self-check program, thereby preventing the photoresistor from receiving an erroneous signal and issuing an erroneous instruction, thereby improving the user experience.

[0071] It should be understood that although the present specification is described according to embodiments, not every embodiment contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0072] The series of detailed descriptions listed above are only specific descriptions of feasible embodiments of the present invention and are not intended to limit the protection scope of the present invention. All equivalent embodiments or changes that do not deviate from the technical spirit of the present invention should be included in the protection scope of the present invention.
