Optionally, the case includes:

and a housing case forming a housing chamber in which the resistive member and the conductive member are disposed.

The refrigerator is characterized in that one of the resistor piece and the conductive piece is fixed on the refrigerator body, and the other is connected with the door body. Therefore, one of the door bodies connected to the refrigerator moves together with the door body that is continuously opened during the opening process of the door body of the refrigerator. Whether the resistive element or the conductive element is connected to the door body, in particular, the conductive element moves relatively to the resistive element, which in turn changes the contact position of the conductive element on the resistive element. That is, the portion of the resistive member that is connected into the lamp circuit is reduced, that is, the resistance value of the resistive member that is connected into the lamp circuit is reduced. Since the resistance value in the lamp circuit decreases, the brightness of the lamp increases. In other words, the brightness of the illumination lamp of the refrigerator increases as the opening degree of the door body increases. Therefore, in the opening process of the door body of the refrigerator, the illumination lamp gradually reaches the maximum brightness from no illumination, and on one hand, the illumination lamp can be prevented from suddenly brightening and shaking eyes of a user. The resistance value in the resistor access line changes linearly along with the opening degree of the door body, so that the brightness of the illuminating lamp also changes gradually in the opening process of the door body, fault type changes can not occur, the user is more comfortable, and the use experience of the user is improved. On the other hand, when the user can take food without completely opening the door body, the illuminating lamp cannot reach the maximum brightness, so that the illuminating effect is ensured, and the consumption of electric energy is reduced.

Further, the refrigerator of the application is characterized in that the resistor piece is fixed on the refrigerator body, and the conductive piece is connected with the door body, so that the conductive piece moves along the resistor piece along with the opening of the door body, and the resistance value of the resistor piece connected into the lighting lamp circuit is reduced along with the increase of the opening degree of the door body. Because the resistance piece has certain length, so be fixed in the box with the great resistance piece of volume, make the less electrically conductive piece of volume follow the resistance piece activity, compare in the great resistance piece of volume, the activity of electrically conductive piece is easier, and skew is less easy to take place moreover, helps simplifying the structure, also is favorable to improving the stability of electrically conductive piece and resistance piece relative activity.

Furthermore, the refrigerator is connected with the door body by the flexible connecting rope, and compared with the refrigerator connected with the door body by the rigid traction piece, the refrigerator is easier to deform by the flexible connecting rope, that is, the connecting rope is not easy to interfere with other rigid structures in the opening process of the door body, so that the door body is prevented from being blocked by the opening process of the door body.

As shown in fig. 1 to 3, in one embodiment, a refrigerator 1 includes a cabinet 10 and a door 20. Wherein the case 10 defines a storage compartment 110. The door 20 is pivotally connected to the case 10 for opening and closing the storage compartment 110. The refrigerator 1 further comprises a resistor 30 and a conductive member 40, wherein the resistor 30 and the conductive member 40 are connected in series in the lighting lamp circuit of the refrigerator 1, one of the resistor 30 and the conductive member 40 is fixed on the refrigerator body 10, and the other is connected with the door body 20, so that the resistor 30 and the conductive member 40 relatively move along with the opening of the door body 20, and the resistance value of the lighting lamp circuit of the refrigerator 1, which is accessed by the resistor 30, is reduced along with the increase of the opening degree of the door body 20.

Referring to fig. 1 to 3, in detail, a lighting lamp 120 is provided at the top of the storage compartment 110. The resistive member 30 and the conductive member 40 are connected in series in the lamp circuit of the lamp 120. The resistor 30 has a certain length, and the longer the resistor 30 is connected to the lighting lamp circuit, the larger the resistance in the lighting lamp circuit, otherwise, the shorter the resistor 30 is connected to the lighting lamp circuit, the smaller the resistance in the lighting lamp circuit. The conductive member 40 contacts with the resistive member 30, and the resistance value of the resistive member 30 connected to the lighting lamp circuit is changed by the relative movement between the conductive member 40 and the resistive member 30.

Therefore, by fixing one of the resistive member 30 and the conductive member 40 to the case 10, the other is connected to the door 20. During the opening of the door 20 of the refrigerator 1, one connected to the door 20 of the refrigerator 1 moves together with the door 20 which is continuously opened. Whether the resistive element 30 or the conductive element 40 is connected to the door 20, the conductive element 40 is relatively movable with respect to the resistive element 30, which in turn changes the contact position of the conductive element 40 on the resistive element 30.

That is, as the door body 20 is continuously opened, the portion of the resistive member 30 connected to the lamp circuit is reduced, i.e., the resistance value of the resistive member 30 connected to the lamp circuit is reduced. Since the resistance value in the lamp circuit decreases, the brightness of the lamp 120 increases. In other words, the brightness of the illumination lamp 120 of the refrigerator 1 increases as the opening degree of the door 20 increases.

Therefore, in the solution of the present embodiment, during the opening process of the door body 20 of the refrigerator 1, the illumination lamp 120 gradually reaches the maximum brightness from no illumination, so that on one hand, the illumination lamp 120 can be prevented from suddenly brightening and shaking the eyes of the user. Moreover, the resistance value in the access line of the resistor 30 is linearly changed along with the opening degree of the door body 20, so that the brightness of the illuminating lamp 120 is gradually changed in the opening process of the door body 20, and no fault type change occurs, so that the user is more comfortable, and the use experience of the user is improved.

On the other hand, when the user can take food without completely opening the door body 20, the illumination lamp 120 does not reach the maximum brightness, which is advantageous to reduce the consumption of electric energy while ensuring the illumination effect.

It should be noted that, in the embodiment of the present application, the refrigerator 1 may be provided with a single or a plurality of storage compartments 110.

In addition, in other embodiments of the present application, the illumination lamp 120 may be disposed in the storage compartment 110 at various positions such as a side wall, a rear wall, and the like.

As shown in fig. 2 to 4, in one embodiment, the resistive member 30 is fixed to the case 10. The conductive member 40 is connected to the door body 20 to move along the resistive member 30 as the door body 20 is opened, so that the length of the resistive member 30 connected to the illumination lamp circuit is reduced.

Referring to fig. 2 to 5, in particular, the resistive member 30 includes a first resistive member 310 and a second resistive member 320. One end of the first resistor 310 is connected to the lighting lamp circuit. One end of the second resistor 320 is connected to the lighting lamp circuit. The movable channel 50 is formed between the first resistive member 310 and the second resistive member 320, the conductive member 40 moves along the movable channel 50, the conductive member 40 contacting the first resistive member 310 and the second resistive member 320 simultaneously turns on the lighting lamp circuit, and the length of the first resistive member 310 and the second resistive member 320 connected to the lighting lamp circuit is reduced along with the opening of the door body 20.

With continued reference to fig. 2-5, in particular, the first resistive member 310 and the second resistive member 320 are the same length. The first and second resistive members 310 and 320 are fixed to the case 10 in the front-rear direction of the refrigerator 1 and aligned in the front-rear direction of the refrigerator 1. One ends of the first and second resistive members 310 and 320 near the front side of the refrigerator 1 are connected to the illumination lamp circuit. The first resistive member 310 and the second resistive member 320 have a space therebetween, i.e., the movable channel 50 is formed.

In addition, an insulating member is connected to the ends of the first and second resistive members 310 and 320, which are remote from the front side of the refrigerator 1. The conductive member 40 is connected to the door body 20 by a traction member. As shown in fig. 2, in the state that the door 20 is closed, the conductive member 40 is located at a position where the insulating member is located without contacting the first resistive member 310 and the second resistive member 320, and the lighting lamp circuit cannot be turned on at this time because there is a space between the first resistive member 310 and the second resistive member 320, and the lighting lamp 120 is not lighted.

Referring to fig. 3, during the opening process of the door 20, the door 20 gradually moves away from the case 10, and then the conductive member 40 is driven by the traction member to move along the movable channel 50. After the conductive member 40 comes into contact with the first resistive member 310 and the second resistive member 320, the lamp circuit is turned on, and the lamp 120 is turned on. Along with the gradual opening of the door 20, the conductive member 40 gradually approaches to one end of the first resistive member 310 and the second resistive member 320 connected to the lighting lamp circuit along the movable channel 50, so that the length of the first resistive member 310 and the second resistive member 320 connected to the lighting lamp circuit is reduced, that is, the resistance value in the lighting lamp circuit is reduced, and the brightness of the lighting lamp 120 is gradually increased. Waiting until the door body 20 is completely opened, the brightness of the illumination lamp 120 reaches the maximum.

In the solution of this embodiment, the resistor 30 is fixed on the case 10, and the conductive member 40 is connected to the door 20, so that the conductive member 40 moves along the resistor 30 along with the opening of the door 10, and the resistance of the resistor 30 connected to the lighting lamp circuit decreases with the increase of the opening degree of the door 20.

Because the resistor 30 has a certain length, the resistor 30 with a larger volume is fixed on the box 10, so that the conductive element 40 with a smaller volume moves along the resistor 30, and compared with the resistor 30 with a larger volume, the conductive element 40 moves more easily and is less prone to deflection, thereby being beneficial to simplifying the structure and improving the stability of the relative movement of the conductive element 40 and the resistor 30.

Further, by providing the first resistive member 310 and the second resistive member 320, the movable channel 50 is formed between the first resistive member 310 and the second resistive member 320. During the movement of the conductive member 40, the conductive member 40 can be clamped by the first resistive member 310 and the second resistive member 320, that is, the movement path 50 functions to define the movement path of the conductive member 40, thereby making the movement of the conductive member 40 more stable.

In the solution of the present embodiment, the insulating member may not be connected to one end of the first resistor 310 and the second resistor 320, but the lighting lamp 120 may not be turned on by making the resistance of the first resistor 310 and the second resistor 320 connected to the lighting lamp circuit particularly large when the door 20 is closed.

In addition, the first resistive member 310 and the second resistive member 320 may both be materials having resistance values that vary with the length of the access. One may be a material whose resistance varies with the length of access and the other may be a good conductor (i.e., the resistance does not substantially vary with the length of access).

It should be noted that, in other embodiments of the present application, the resistor 30 may include only one resistor, and one end thereof is connected to the lighting circuit. The conductive member 40 is also connected to the lighting circuit, and at this time, the conductive member 40 moves along the resistive member 30 to also play a role in changing the resistance of the lighting circuit.

Note that, the brightness of the illumination lamp 120 may be maximized when the door 20 is opened to a degree close to full opening.

Further, as shown in fig. 6, a positioning structure is provided between the conductive member 40 and the resistive member 30 to limit the movement of the conductive member 40. Specifically, the positioning structure is a limiting groove 410 disposed in the conductive member 40, and the conductive member 40 contacting the resistive member 30 makes the resistive member 30 embedded in the limiting groove 410.

Referring to fig. 6, specifically, the conductive member 40 is provided with two limiting grooves 410, and the sizes of the two limiting grooves 410 are equal to those of the first resistive member 310 and the second resistive member 320, respectively. Therefore, when the first and second resistive members 310 and 320 are inserted into the limiting groove 410, good contact with the conductive member 40 can be ensured without obstructing the movement of the conductive member 40.

It will be appreciated by those skilled in the art that by providing a locating structure between the conductive member 40 and the resistive member 30, the movement of the conductive member 40 can be limited, preventing deflection of the conductive member 40 and thus helping to ensure contact between the conductive member 40 and the resistive member 30.

In addition, by arranging the limiting groove 410 on the conductive member 40, the contact area between the conductive member 40 and the resistive member 30 is larger while the conductive member 40 is limited, which is beneficial to improving the contact effect between the conductive member 40 and the resistive member 30.

It should be noted that, in other embodiments of the present application, the conductive element 40 and the resistive element 30 may also have a protrusion disposed between one of them, and a recess disposed between the other one of them to limit the conductive element 40. For example, a groove extending along the moving track of the conductive member 40 is provided on the side of the resistive member 30 facing the conductive member 40, and a protrusion embedded in the groove is provided on the conductive member 40.

In addition, in the case where the resistor 30 includes only one, it is preferable that the conductive member 40 is sleeved outside the resistor 30, that is, the positioning structure is a through hole provided on the conductive member 40.

Referring back to fig. 3-4, in one embodiment, the conductive element 40 is connected to the door body 20 by a flexible connecting cord 60. An elastic member 70 is disposed between the conductive member 40 and the case 10, so that the conductive member 40 returns to the original position along with the closing of the door 20 under the traction of the elastic member 70.

Specifically, one end of the connection cord 60 is connected to the conductive member 40, and the other end is connected to the door body 20. During the opening process of the door body 20, the door body 20 pulls the conductive member 40 through the connection rope 60, so that the conductive member 40 moves along the resistive member 30.

In addition, the elastic member 70 is a spring, one end of the elastic member 70 is connected to the conductive member 40, and the other end is fixed to the case 10. During the movement of the conductive member 20 along with the gradually opened door body 20, the conductive member 20 continuously stretches the elastic member 70, so that the elastic member 70 accumulates elastic force. In the process of gradually closing the door 20, the tension of the connecting rope 60 on the conductive member 40 is firstly lost, and at this time, the conductive member 40 receives the tension of the elastic member 70, so that the conductive member 40 gradually returns to the original position under the action of the tension of the elastic member 70.

In the solution of this embodiment, by connecting the conductive element 40 with the door body 20 by using the flexible connection rope 60, the flexible connection rope 60 is easier to deform compared with connecting the conductive element 40 with the door body 20 by using a rigid traction element, that is, the connection rope 60 is not easy to interfere with other rigid structures during the opening process of the door body 20, so as to avoid blocking the opening of the door body 20. Moreover, the connecting rope 60 requires less space for movement, which is advantageous in reducing the occupied space.

It should be noted that, in other embodiments of the present application, the conductive member 40 and the door body 20 may be connected by a rigid traction member, such as a connecting rod. For example, both ends of the connection rod are connected to the conductive member 40 and the door body 20 in a universal rotation manner, respectively.

The elastic member 70 may be an elastic structure such as an elastic string. In addition, when the elastic member 70 is a member that is compressed to generate elastic force, such as a spring, it may be disposed on a side of the conductive member 40 near the door body 20, that is, the elastic member 70 may be pressed when the conductive member 40 moves along with the door body 20, so that the elastic member 70 accumulates elastic force that can restore the conductive member 40.

Referring to fig. 2 to 3, further, the door body 20 is provided with a fixing member 210 and a pulley 220, and one end of the connection rope 60 remote from the conductive member 40 is fixed to the fixing member 210 by passing around the pulley 220

Specifically, the fixing member 210 and the pulley 220 are distributed in the door body 20 in a direction away from the pivot axis of the door body 20, i.e., the fixing member 210 is closer to the pivot axis than the pulley 220. One end of the connection string 60 is connected to the conductive member 40, and the other end is connected to the fixing member 210. The portion of the connection cord 60 between the conductive member 40 and the fixing member 210 can be in contact with the pulley 220.

Those skilled in the art will appreciate that by providing the pulley 220 on the door body 20, the movement of the conductive member 40 can be made easier.

It should be noted that, in other embodiments of the present application, the pulley 220 may not be provided.

As shown in fig. 4, in one embodiment, the case 10 includes a receiving box 130. The accommodating case 130 forms an accommodating chamber 131, and the resistive member 30 and the conductive member 40 are disposed in the accommodating chamber 131.

Specifically, the housing case 130 has a cylindrical shape, and a cylindrical housing chamber 131 is hollowed out. The first resistive member 310 and the second resistive member 320 are disposed within the accommodating chamber 131 and are disposed opposite to each other against the inner wall of the accommodating case 130. The conductive member 40 is also attached to the inner wall of the housing case 130 except for the portion provided with the stopper groove 410. The elastic member 70 has one end connected to the conductive member 40 and the other end connected to the bottom wall of the accommodating case 130.

In the solution of the present embodiment, by providing the housing case 130 in the case 10, the resistive member 30 and the conductive member 40 can be provided in the housing chamber 131 of the housing case 130. Therefore, the components such as the resistive member 30 and the conductive member 40 may be uniformly installed in the case 10 after being installed in the accommodating case 130, so that the installation process is more convenient. Moreover, the accommodating case 130 is advantageous in further securing the moving trace of the conductive member 40.

For connection of the resistor 30 and the lighting lamp circuit, a connector extending from the housing case 130 may be provided to the resistor 30, and the connector may be connected to an external power line.

As shown in fig. 7, in one embodiment, the conductive member 40 is fixed to the case 10. The resistive member 30 is connected to the door body 20 to move relative to the conductive member 40 as the door body 20 is opened, so that the length of the resistive member 30 connected to the illumination lamp circuit is reduced.

Specifically, the resistor 30 includes a first portion 330 and a second portion 340, a space is provided between the first portion 330 and the second portion 340, and the first portion 330 and the second portion 340 are fixedly connected by a conductive structure. The conductive member 40 includes a first conductive member 420 and a second conductive member 430, and the first conductive member 420 and the second conductive member 430 are respectively connected to the illumination lamp circuit. And, the first and second portions 330 and 340 can be respectively contacted with the first and second conductive members 420 and 430 and moved relative to the first and second conductive members 420 and 430 so that the length of the resistive member 30 connected between the first and second conductive members 420 and 430 is reduced as the door body 20 is opened.

Referring to fig. 7, specifically, the first portion 330 and the second portion 340 of the resistive member 30 are identical in length, and both extend in the front-rear direction of the refrigerator 1. One end of the first portion 330 and the second portion 340 are connected to an insulating member, and the other ends thereof are fixedly connected by a conductive structure, i.e., the first portion 330, the second portion and the conductive structure form a substantially "U" shaped structure.

It should be noted that, the resistor 30 may be an integrally formed "U" structure, that is, a portion of the resistor 30 itself is a conductive structure. The first portion 330, the second portion 340 and the conductive structure may also be formed separately and then secured together to form a "U" shaped structure.

In the state that the door 20 is closed, the first conductive member 420 and the second conductive member 430 are respectively in contact with the insulating members at the ends of the first portion 330 and the second portion 340, so that the illumination lamp circuit cannot be turned on at this time, and the illumination lamp 120 is not turned on.

During the opening process of the door 20, the door 20 gradually moves away from the case 10, and then the resistor 30 is driven to move by the traction element. The first portion 330 and the second portion 340 of the resistive member 30 come into contact with the first conductive member 420 and the second conductive member 430, respectively, such that the lamp circuit is turned on and the lamp 120 is lighted. As the door 20 is gradually opened, the contact position of the first conductive member 420 and the first portion 330 is gradually close to the end of the conductive structure, and the contact position of the second conductive member 430 and the second portion 340 is also gradually close to the end of the conductive structure. Thereby reducing the length of the resistive member 30 connected to the lamp circuit, that is, the resistance value in the lamp circuit is reduced and the brightness of the lamp 120 is increased.

It should be noted that, in some other embodiments of the present application, the resistor 30 may be a linear resistor rod, and one end of the resistor rod is connected to the door body, and the other end of the resistor rod is connected to the lighting circuit. When it moves relative to the conductive member 40 as the door 20 is opened, the length of itself that is connected to the lamp circuit is reduced.

In addition, the connection structure between the resistor 30 and the door 20 may be set with reference to the connection manner in the foregoing embodiment, which is not described herein.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the application have been shown and described herein in detail, many other variations or modifications of the application consistent with the principles of the application may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the application. Accordingly, the scope of the present application should be understood and deemed to cover all such other variations or modifications.
