DETAILED DESCRIPTION

[0027] 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.

[0028] 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".

[0029] 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.

[0030] The present invention provides a refrigeration device, such as Figures 1 to 5 As shown, the refrigeration device includes a box body 10, a door body 20 for closing and opening the box body 10, and the refrigeration device also includes a signal transmission component (not shown) and a main control device (not shown) connected to the signal transmission component. The signal transmission component includes a signal sending unit and a signal receiving unit. One of the signal sending unit and the signal receiving unit is located on the door body 20 and connected to the display unit, and the other is located on the box body 10 and connected to the main control device. The display unit on the door body 20 is also connected to the main control device. The refrigeration device of the present invention realizes a contactless communication connection between the main control device located in the box body 10 and the display unit located on the door body 20 through the signal transmission component. There is no need to install wires in the hinge shaft of the door body 20, which can effectively reduce the thickness of the door body 20 and meet the user's demand for an ultra-thin door body 20.

[0031] Among them, Figure 2 and Figure 5 As shown, 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 a through hole 111 penetrating along the thickness of the hinge plate 11 is provided on the hinge plate 11.

[0032] like Figure 3 As shown, a hinge shaft 21 is provided at the upper end of the door body 20, and the hinge shaft 21 is pivotally connected to 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, and the signal receiving unit or the signal sending unit is located in the hinge box 12.

[0033] like Figure 5 As shown, the hinge shaft 21 has a receiving cavity 211 which is open upwards, and the signal sending unit or the signal receiving unit is located in the receiving cavity 211 .

[0034] Preferably, the hinge shaft 21 is made of a VC liquid cooling plate, which dissipates heat quickly and can provide a working space with a relatively safe temperature for the signal sending unit or the signal receiving unit.

[0035] As a preferred embodiment of the present invention, the signal sending unit is arranged in the accommodating cavity 211, and the signal receiving unit is located in the hinge box 12 above the hinge axis 21. Preferably, the signal sending unit and the signal receiving unit are arranged at an axial interval along the hinge axis 21, and the signal receiving unit is not disturbed when receiving the signal.

[0036] Preferably, if Figure 4 and Figure 5 As shown, the signal sending unit is a light emitting element 31 , and the signal receiving unit is a photoresistor 32 . The photoresistor 32 is located directly above the light emitting element 31 .

[0037] Of course, the signal transmission component may also transmit a signal by sending an acoustic signal through the signal sending unit and receiving the acoustic signal through the signal receiving unit, which is also within the protection scope of the present invention.

[0038] The main control device is electrically and communicatively connected to the signal sending unit and the signal receiving unit respectively. The refrigeration equipment also includes a first cable group 33 arranged in the hinge box to connect the signal receiving unit, and a second cable group 34 arranged in the receiving cavity 211 to connect the signal transmitting unit. Specifically, the first cable group 33 connects the main control device and the photoresistor 32, and the second cable group 34 connects the light-emitting component 31 and the display unit on the door body 20.

[0039] As another preferred embodiment of the present invention, Figure 5 As shown, 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 on the photoresistor 32, thereby improving the degree to which the photoresistor 32 senses light, and further improving the sensitivity of the photoresistor 32 to sense light.

[0040] As another preferred embodiment of the present invention, the refrigeration device further comprises an auxiliary power supply system 40 for auxiliary power supply to the light emitting element 31, and is used to power the light emitting element 31 when performing self-check on the signal transmission condition of the signal transmission component.

[0041] Furthermore, if Figure 5 As shown, the auxiliary power supply system 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 main control device disconnects the power supply to the light-emitting component 31, and controls the power storage module 42 to power the light-emitting component 31, so as to determine whether the signal transmission component fails.

[0042] 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.

[0043] In this embodiment, 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 both can receive the light signal of the light-emitting element 31 at the same time.

[0044] Preferably, the photovoltaic panel 41 and the photoresistor 32 are adjacent to and arranged side by side.

[0045] 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.

[0046] In this embodiment, the power storage module 42 is located above the photovoltaic panel 41 and the photoresistor 32. Preferably, the power storage module 42 is located in the hinge box 12. The refrigeration device 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.

[0047] 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.

[0048] 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.

[0049] The refrigeration device also includes a storage room located in the box body 10, and the refrigeration device also includes a temperature sensing unit (not shown) for sensing the indoor temperature of the storage room, and / or a humidity sensing unit (not shown) for sensing the humidity of the storage room, and / or a door detection unit (not shown) for detecting the number of times the door is opened, and the temperature sensing unit and / or the humidity sensing unit and / or the door detection unit are communicatively connected to the main control unit.

[0050] Under normal working conditions, the main control unit detects that the temperature of the storage compartment is too high and displays it on the display screen of the door body 20. The user adjusts the temperature through the buttons of the door body 20. The main control unit receives the command to adjust the temperature, supplies power to the light-emitting component 31, controls the light-emitting component 31 to emit light and flash a preset number of times, the photoresistor 32 receives the signal and transmits it to the damper of the refrigerator. At this time, the damper opens, and the cold air in the refrigeration compartment blows into the storage compartment. The temperature sensing unit detects that the temperature reaches the set temperature, and the main control unit controls the light-emitting component 31 to be powered and flash a preset number of times. The photoresistor 32 receives the signal and transmits it to the main control unit, and the main control unit controls the damper of the cabinet to be closed.

[0051] When the user's refrigerator door 20 is not closed, the main control device supplies power to the light-emitting component 31 and controls the light-emitting component 31 to flash continuously for multiple times. The photoresistor 32 receives the signal, issues a work instruction to the main control device, and controls the alarm of the refrigeration equipment to sound an alarm, reminding the user to close the door 20.

[0052] When the signal transmission component needs to be self-checked, the power storage module 42 is controlled to supply power to the light-emitting component 31 to determine whether the light-emitting component 31 or the power supply unit of the main control device fails.

[0053] To summarize, the refrigeration equipment of the present invention realizes a contactless communication connection between the main control device located in the box and the display unit located on the door body 20 through a signal transmission component. There is no need to install wires in the hinge shaft 21 of the door body 20, which can effectively reduce the thickness of the door body 20 and meet the user's demand for an ultra-thin door body 20.
