Detailed Description

Hereinafter, a refrigerator according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

It should be mentioned that, the refrigerator refrigerating chamber door body of the present invention is provided with a power supply terminal inside, the power supply terminal is used for supplying power to the parts to be connected (for example, an ice maker arranged on the refrigerating chamber door body), and an all-pole disconnecting switch electrically connected with the power supply terminal is additionally provided for controlling the power-off and power-supply of the power supply terminal. The all-pole off switch is fixed by a protective case fixed inside a door body of a refrigerating chamber of the refrigerator, and the all-pole off switch is accommodated in the protective case. According to a preferred embodiment of the invention, which will be described below, the protective casing comprises in particular a frame 3, a first structural element 4, and a second structural element 5. Specific structures of the frame, the first structural member, and the second structural member according to preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Fig. 1 schematically shows a portion of a refrigerating compartment door liner of a refrigerator according to a preferred embodiment of the present invention, and an all-pole disconnecting switch 1 and a power supply terminal 2 are received in a frame member 3 formed of the refrigerating compartment door liner. As can be seen from fig. 1, in this preferred embodiment of the present invention, the all-pole disconnecting switch 1 and the power supply terminal 2, which are electrically connected to each other, are provided along the top side (direction in the normal use state of the refrigerator) 33 of the frame member 3, and are separated from each other by a partition plate 31, which is formed integrally with the frame member 3. The power supply terminal 2 is used for supplying power to a part to be connected (such as an ice maker arranged on a refrigerating chamber door body), and the all-pole disconnecting switch is used for controlling the power-off and the power-on of the power supply terminal. It should be mentioned that in the present preferred embodiment, the omnipole disconnection switch is arranged horizontally (i.e. with its switching section 11 vertically downwards in the normal use condition of the refrigerator), in which case, in order to guarantee the safety of the operator to the maximum extent, the present embodiment adopts the design concept of isolating the omnipole disconnection switch and the power supply terminal from each other, and thus provides the partition, which, depending on the actual situation, may also be formed as part of the first structural member 4 described below, or as a separate component connected to the frame member 3 or the first structural member 4, or in some arrangements the partition 31 may be removed.

In order to eliminate the risk of electric shock due to carelessness in operation. According to the preferred embodiment, the omnipole disconnect switch needs to be securely fixed within the frame member and the switching portion of the omnipole disconnect switch is not accessible to an operator during the process of disconnecting the parts to be connected. Thus, as shown in fig. 2A and 2B, in the present preferred embodiment, there is provided a first structural member 4 for fixing and covering the all-pole disconnecting switch, which includes a first engaging portion 41, a covering portion 42, and a fixing portion 44. Wherein the first engaging portion 41 is substantially L-shaped, is snap-fitted to a portion of the frame member, and is fixedly coupled to the opening portion 35 of the frame member 3 by means of screws (as indicated by

reference numerals

71 and 72 in fig. 4). The cover portion 42 extends from the first engaging portion 41, faces the inside of the frame member 3 in a state where the first structural member is mounted in place, and shields the switch side 12 of the all-pole disconnecting switch 1, and an opening 43 is provided at a position corresponding to the switch portion 11 of the all-pole disconnecting switch. The fixing portion 44 extends from the first engaging portion 41, faces the inside of the frame member 3 in a state where the first structural member is mounted in place, and abuts on the switch side 12 of the omnipole disconnecting switch to fix the omnipole disconnecting switch 1 against the top side 33 of the frame member. Here, other structures for fixing the all-pole off switch may be employed. As can be seen in fig. 4, when the first structural part 4 is mounted in place, the omnipole disconnector 1 is accommodated completely inside the space which is jointly defined by the first structural part 4 and the frame part 3. Therefore, the all-pole disconnecting switch 1 is completely isolated from the power supply terminal 2, and therefore, in the disconnecting operation of the part to be connected and the power supply terminal, the all-pole disconnecting switch cannot be touched by hands, and the personal safety of operators is ensured. As shown in fig. 5, after the first structural member 4 is mounted in place, the all-pole off switch is in an off state because of this time. Therefore, the connection end of the member to be connected (indicated by reference numeral 6 in fig. 5) can be securely engaged with the power supply terminal, and this operation does not pose any danger to the operator. Meanwhile, in the present embodiment, when the first structural member 4 is mounted in place, it covers only a part of the upper portion of the power supply terminal 2 to facilitate the operation of attaching and detaching the terminal of the member to be connected to the power supply terminal. In addition, a mating surface of the first structural member that is engaged with a second structural member (described in detail below) is provided with a mating groove 45 for mating with a mating protrusion on the second structural member.

Fig. 3A and 3B are perspective views illustrating different angles of the second structural member 5 according to a preferred embodiment of the present invention, and it can be seen that the second structural member 5 includes a second coupling portion 52 formed to correspond to the shape of the first coupling portion 41 of the first structural member, an intermediate coupling member 53 extended from the second coupling portion 52, and a projection 51 formed on the intermediate coupling member. The second engaging portion 52 is a substantially L-shaped structure (matching with the L-shape of the first structural member), and a side thereof combined with the first structural member is provided with a plug protrusion 55 for matching with the plug groove 45 of the first structural member to detachably connect the second structural member with the first structural member. In the state where the second structural member is mounted in place, the intermediate connecting member extends toward the inside of the frame member, and the projection 51 extends from the intermediate connecting member toward the opening 43 of the first structural member, and the projection 51 is shaped and long to be able to project into the opening 43 of the first structural member 4 to press the switch portion 11 of the all-pole disconnecting switch 1 to close the all-pole disconnecting switch, and when the projection is out of contact with the switch portion of the all-pole disconnecting switch, the all-pole disconnecting switch is opened. Here, the second structural element is detachably joined to the first structural element 4 by means of a plug-in connection, for the purpose of disassembly, but other connections are possible depending on the circumstances. The second joint portion 52 is also formed with a fastening portion 54 for fastening to the frame member 3. When the second structural member 5 is mounted in place (as shown in fig. 6), it forms a space accommodating the power supply terminal 2 together with the first structural member and the frame member 3, and the projection 51 projects into the opening 43 to press the switch portion 11 so that the all-pole opening switch 1 is closed. Since the power supply terminal 2 needs to be connected with the member to be connected to supply power to the member to be connected, a lead port 34 for guiding a lead (shown as 61 in fig. 5) of a terminal of the member to be connected is also formed on the frame member 3.

In the present preferred embodiment, since the member to be connected is detachable, the second structural member 5 is also configured to be detachably connected with the first structural member 4 and the frame member 3 for convenience. Therefore, when the second structural member 5 is mounted in place, the projection 51 presses the switch portion 11 of the all-pole disconnecting switch 1, so that the all-pole disconnecting switch is in a closed state, and at this time, the power supply terminal 2 is shielded by the second structural member 5 and thus cannot be reached by a human hand, so that even if the power supply terminal is not connected to any component, the danger of electric shock can be avoided. When the connecting component needs to be disassembled or connected with the component to be connected, the buckling part 54 on the second structural component 5 is only needed to be opened, and the second structural component 5 is only needed to be detached from the first structural component 4. Since the projection 51 on the second structural member 5 is out of contact with the switch portion 11 of the all-pole disconnecting switch 1, the all-pole disconnecting switch is disconnected to disconnect the power supply terminal 2, and thus, it is possible to safely detach the connecting member or connect the member to be connected to the power supply terminal.

In various practical applications, the above-described respective components may be replaced, deleted, or structurally modified, for example, the partition plate may be eliminated, and the first structural member may be configured to cover the switching portion of the all-pole disconnecting switch and maintain the fixed structure of the all-pole disconnecting switch. Alternatively, the all-pole disconnecting switch may be fixedly provided along the side wall 32 of the frame member 3 with the switch portion 11 of the all-pole disconnecting switch facing the side wall 32 and spaced from the side wall by a distance (the spaced distance may be secured by forming spacers on the side wall 32 on both sides of the switch portion) only for inserting a finger or other auxiliary tool (structure) to press the switch portion 11 (in this case, only the first structural member may be provided and the second structural member may be omitted), which also makes it possible to avoid the risk of electric shock due to the erroneous operation of the operator.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications, changes and omissions may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
