The refrigeration equipment in the embodiment of the utility model is a refrigerator, the refrigerator comprises a refrigerator body 300 and a door body for opening and closing the refrigerator body 300, and a hinge assembly is arranged on the refrigerator body 300. In an embodiment of the present utility model, the hinge box 100 includes a top wall 130, and a plurality of side walls 140 extending from the periphery of the top wall 130. And, the inside of the hinge box 100 is disposed toward the top surface of the refrigerator case 300, and the hinge receiving cavity 110 extends from the case 300 toward the door so that the hinge is engaged with the hinge shaft to rotatably connect the door to the case 300.

In the embodiment of the present utility model, the main control board 200 refers to a weak current control board in the refrigerator, and the weak current control board generally controls devices such as a fan damper, a door switch, an illumination lamp, a sensor and/or a display panel of the refrigerator. The weak current control board is connected with the power supply control board to realize power supply. In other embodiments, the main control board 200 may also refer to a power control board, or a sum of a weak current control board and a power control board.

As shown in fig. 2, the wall of the main control board accommodating cavity 120 is provided with an access opening 160 communicated with the outside, and the access opening 160 is disposed at a position close to the main control board 200. The main control board 200 is placed in the hinge box 100, and since the hinge box 100 is fastened at the top of the box body, the main control board 200 cannot be seen or contacted after normal installation, in order to facilitate maintenance work such as reading and writing programs and electrical detection on the main control board 200, an access hole 160 is arranged at a position of the hinge box 100 close to the main control board 200, and an extendable interface is arranged on the main control board 200, so that maintenance operation can be performed on the main control board 200 without disassembling the hinge box 100. Specifically, the hinge box 100 has four corners, and the access opening 160 is provided at one of the corners near the main control panel 200. In other embodiments, the access opening 160 may be provided not at one of the four corners of the hinge box 100, but on the side wall 140 or the top wall 130 of the hinge box 100.

In the embodiment of the present utility model, the access opening 160 is disposed on a side of the cavity wall of the main control board accommodating cavity 120 away from the hinge accommodating cavity 110. The access opening 160 is disposed away from the hinge accommodating cavity 110, so as to further prevent the water vapor in the hinge accommodating cavity 110 from adversely affecting the main control board 200 in the main control board accommodating cavity 120.

The access opening 160 is provided with a cover plate 170 for closing the access opening 160, and the cover plate 170 is detachably connected with the access opening 160. In order to prevent moisture from entering the hinge box 100, a cover plate 170 is added to the access opening 160, and the cover plate 170 is movably connected to the access opening 160. In an embodiment of the present utility model, the cover plate 170 is detachably coupled to the edge of the access opening 160 by a snap. In this way, in a daily state, the access port 160 is closed by the cover plate 170, so that water vapor is prevented from entering the main control board accommodating cavity 120 from the access port 160. When the main control board 200 needs to be overhauled, the cover plate 170 can be detached, so that operations such as electric detection and the like are performed on the main control board 200 through the overhauling port 160 and the extensible interface on the main control board 200. In other embodiments, the cover plate can also be rotatably connected with the access opening through the rotating shaft, and when the maintenance is needed, the cover plate is rotated by a certain angle to enable the access opening to leak, so that the main control panel can be electrically detected through the extendable interface.

The edge of the access opening 160 is formed with a guide groove 161. As shown in fig. 2, the access opening 160 edges extend along the side wall 140 to the top wall 130 to the side wall 140 of the hinge box 100 in that order. If water enters the access opening 160, water can flow out to the side walls 140 on both sides preferentially along the guide grooves 161 on the edge, so that water is prevented from flowing into the hinge accommodating cavity 110.

The cover plate 170 is provided with a flange 171 disposed toward the guide groove 161, and the flange 171 is shaped to fit the guide groove 161. When the flange 171 facing the guide groove 161 is formed on the periphery of the cover 170, if water enters along the connection between the cover 170 and the access hole 160, the water flows out to the side walls 140 on both sides preferentially along the gap between the flange 171 and the guide groove 161, so that the water is prevented from flowing into the hinge accommodating cavity 110, and the water can be drained while preventing water from flowing out.

The partition is a partition 150 extending inside the hinge box 100 in a direction perpendicular to the length of the hinge box 100. The cavity of the hinge box 100 can be divided into two by providing the partition 150, thereby protecting the main control board 200 from moisture. Specifically, the hinge box 100 is generally rectangular and has an extended portion at one of its corners that extends out of the box and adjacent to the door when the hinge box is snapped onto the refrigerator cabinet. The partition 150 extends along a length direction perpendicular to the hinge box 100, so that the hinge box 100 can be divided into two cavities in the length direction, a hinge is placed in a cavity adjacent to the extending portion, and the main control board 200 is placed in the other cavity, and the separation is reasonable.

Specifically, the spacer 150 extends downwardly from the top wall 130 of the hinge box 100 to be flush with the bottom surface of the side wall 140, or may be slightly below the bottom surface of the side wall 140. The partition 150 may be provided with a notch 151 for the connection line extending from the main control board 200 to pass through. Specifically, the connection line extends from the main control board 200 to the notch 151 on the partition 150 and extends out through the hinge receiving chamber 110 into the cabinet of the refrigerator to connect devices in the cabinet that need to be controlled by the main control board 200, such as an illumination lamp, a temperature sensor, and/or a humidity sensor, etc. disposed in the cabinet of the refrigerator.

As shown in fig. 1, a temperature and humidity sensor 111 is further disposed in the hinge accommodating cavity 110, and the temperature and humidity sensor 111 is in communication connection with the main control board 200. The temperature and humidity sensor 111 is used for detecting the temperature and humidity of the surrounding environment of the refrigerator, the temperature and humidity sensor 111 sends the detected ambient temperature and humidity data to the main control board 200, and the main control board 200 executes preset control instructions according to the data. The sensor for detecting the ambient temperature and humidity is arranged in the hinge box, so that the sensor can be waterproof and dustproof under the condition of accurately detecting the temperature and humidity, and the problems of unattractive appearance and easy damage caused by exposing the sensor are avoided.

In order that the temperature and humidity sensor 111 can more precisely detect the ambient temperature and humidity, a plurality of ventilation holes 112 are formed in the top wall 130 or the side wall 140 of the hinge box 100. Specifically, the vent 112 is located in the hinge receiving cavity 110 and is located away from the main control board receiving cavity 120. And the vent holes are arranged close to the temperature and humidity sensor.

In addition, since the vent 112 is provided with a risk of water inflow, the partition 150 can prevent the main control panel 200 from being damaged by short-circuit caused by water entering from the vent 112. Meanwhile, the partition board 150 and the hinge box 100 are made of the same plastic material, so that the heat dissipation performance is good, and the heat of the main control board 200 can be transferred to the hinge accommodating cavity 110 through the partition board 150 and then transferred to the external environment through the vent 112. That is, the inside of the hinge box 100 can be ventilated and radiated through the partition 150 and the vent 112.

As shown in fig. 1, the main control board 200 is disposed near the top wall 130 of the hinge box 100, and when the hinge box 100 is fastened to the top of the box, if water is present at the top of the box, the water does not flow onto the main control board 200. And because the hinge box 100 is plastic, the top wall 130 immediately adjacent to the hinge cover can also help the main control board 200 dissipate heat to the environment. Thus, the main control board 200 is disposed close to the top wall 130 of the hinge box 100 to achieve both waterproof and heat dissipation effects.

As shown in fig. 1, the main control board 200 includes an interactive display unit 210 and a control unit 220, wherein the interactive display unit 210 receives control of the control unit 220 and outputs a display signal, and the control unit 220 receives an instruction signal from the interactive display unit 210.

The interactive display portion 210 is disposed at an angle to the control portion 220, and in particular, the interactive display portion 210 is parallel to the side wall 140 of the hinge box 100, and the control portion 220 is disposed on the top wall 130 of the hinge box 100, that is, both are disposed perpendicular to each other. Specifically, the interactive display portion 210 and the control portion 220 are formed by bending a single main control board 200, limited to the structure of the hinge box 100. In the embodiment of the present utility model, the interactive display unit 210 and the control unit 220 may be physically separated into two plates and connected by an internal connection line, and disposed perpendicular to each other. In other embodiments, the interactive display portion and the control portion may be implemented to be perpendicular to each other using a flexible circuit board.

The interactive display 210 is fixedly connected to the sidewall 140. The interactive display 210 is disposed parallel to the side walls 140 of the hinge box 100. The interactive display portion 210 includes a fixing portion 213 for connecting with the side wall 140 of the hinge box 100. The interactive display portion 210 includes a first end 214 and a second end 215 opposite to each other in a width direction, and the first end 214 is far from the top wall 130 of the hinge box 100. The fixing portion 213 is disposed at the first end 214.

Specifically, the interactive display 210 is disposed on the hinge box 100 near the side wall 140 of the refrigerator door. Thus, the user can see the contents displayed by the interactive display portion 210 while facing the door body, and perform an operation of controlling the refrigerator with respect to the interactive display portion 210.

The top wall 130 of the hinge box 100 is provided with a limiting portion 180 extending inwards, and the second end 215 of the interactive display portion 210 is connected with the limiting portion 180 to limit the displacement of the second end 215. Specifically, the interactive display portion 210 is plate-shaped, and when it is fixed to the side wall 140, it is generally preferable to provide the fixing portion 213 in the middle of its width (for example, a through hole through which a screw passes), but since the hinge box 100 is enclosed by the top wall 130 and the side wall 140, a cavity is formed after enclosing, and it is very inconvenient to fix the interactive display portion 210 from the inside of the cavity, the fixing portion 213 is provided at the first end 214 of the interactive display portion 210, that is, a position far from the top wall 130. However, when the second end 215 of the plate-shaped interactive display portion 210 is fixed (for example, when the screw is mounted), the second end 215 of the interactive display portion 210 may be offset, so that the interactive display portion 210 is not parallel to the side wall 140 any more, and therefore, in order to avoid the position of the second end 215, the inwardly extending stopper 180 is provided on the top wall 130, the second end 215 of the interactive display portion 210 is first mounted on the stopper 180, so that the displacement of the second end 215 is limited, and finally, when the interactive display portion 210 is fixed (for example, when the screw is mounted on the fixing portion 213 and the side wall 140), the interactive display portion 210 may not be offset, and may always remain parallel to the side wall 140. Specifically, the second end 215 of the interactive display portion 210 is also provided with a stop portion, and the stop portion is engaged with the limit portion 180 on the hinge box 100, so as to limit the movement of the interactive display portion 210 on the plane on which the top wall 130 of the hinge box 100 is located.

As shown in fig. 3, a display through hole 141 is formed in the side wall 140 of the hinge box 100, and the display through hole 141 is disposed corresponding to the interactive display portion 210. The interactive display portion 210 includes a display panel and touch keys disposed on the display panel, and the number and shape of the display through holes 141 are adapted to the touch keys. Therefore, each touch key can be displayed from the through hole, and the control of a user is facilitated. In addition, a display film 216 is provided on the outer side of the side wall 140 of the hinge box 100, and the display film 216 is transparent at the position corresponding to the touch key, so that various data and touch keys can be displayed.

As shown in fig. 1, the main control board 200 is fixed to the top wall 130 of the hinge box 100 by screws. Meanwhile, the opposite sides of the main control board 200 are also provided with fastening structures 230, the main control board 200 is firstly fixed on the top wall 130 of the hinge box 100 through fastening, and in order to further avoid the shaking of the main control board 200, screws are fixed on the main control board 200 and the top wall 130.

In another embodiment, as shown in fig. 4, the box 300 is further provided with a second hinge box 400, and a display module is disposed in the second hinge box 400, and the display module receives control of a main control board and outputs a display signal, and the main control board receives an indication signal from the display module. Specifically, for the two-door refrigerator, two hinge boxes are symmetrically disposed at the top of the case 300, the main control panel may be disposed in one of the hinge boxes 100 (the main control panel herein includes only the control portion and does not include the interactive display portion), and the display module may be disposed in the other hinge box 400. The display module receives the control of the main control board 200 and outputs a display signal, and the main control board 200 receives an indication signal from the display module, so that interaction can be performed between the main control board arranged in one of the hinge boxes and the display module arranged in the other hinge box. Therefore, the complex step of arranging the display module inside the refrigerator door body can be omitted, the process is simple, and the cost can be reduced as well.

It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.
