Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to a contact switch assembly for a refrigerator. Background Art

[0002] In modern home appliance technology, electronically controlled refrigerators have become an indispensable part of family life. At present, the control panel of electronically controlled refrigerators is usually cleverly set on the refrigerator body, and the specific location may be on the top or back of the refrigerator. This design not only facilitates the overall control of the internal system of the refrigerator, but also ensures that the control panel can operate in a relatively safe environment that is not easily disturbed by the outside world. The temperature display and operation control functions of the refrigerator are mostly realized by the display panel installed on the refrigerator door. These display panels, as part of the refrigerator door, provide users with intuitive temperature information and a convenient operation interface.

[0003] It is worth noting that the refrigerator body and door are two independent parts, which are tightly and firmly connected together through hinges, ensuring the overall stability and durability of the refrigerator. However, this structure also brings certain challenges to the internal communication of the electronically controlled refrigerator. In order to connect the control panel on the cabinet and the display panel on the door to realize information exchange between the two, it is usually necessary to pass the relevant communication harness through the shaft hole of the door hinge shaft.

[0004] However, this traditional wiring harness connection method has exposed many problems in practical applications. First, due to the relatively complicated process of crossing and docking the wiring harness, it often takes a lot of time and manpower, which reduces the installation efficiency of the production line. Secondly, in order to ensure that the wiring harness can smoothly pass through the shaft hole and successfully dock, it is usually necessary to reserve too long a wiring harness. This not only increases the material cost, but also may cause the wiring harness to be messy inside the refrigerator, increasing the difficulty of maintenance. What's more serious is that with the continuous complexity of the functions of refrigerator products, the number of wiring harnesses required is also increasing. This causes the wiring harness assembly to become too thick, or the size of the wiring harness terminal to become too large, so that it cannot pass through the shaft hole smoothly. Since the aperture of the shaft hole generally has a limited value and cannot be increased indefinitely, this wiring harness connection method is greatly restricted in use. This not only affects the overall performance and user experience of the refrigerator, but may also bring unnecessary troubles to the production and maintenance of the refrigerator.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 this field without creative work are within the scope of protection of the present invention.

[0050] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0051] It should be noted that, in this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0052] Figure 1 The present invention is a front view of a refrigerator having a refrigerator contact switch assembly.

[0053] Figure 2 for Figure 1 A longitudinal partial cross-sectional view of .

[0054] Figure 4 The present invention provides a top view of a refrigerator having a refrigerator contact switch assembly.

[0055] See also Figure 1 , Figure 2 as well as Figure 4 It can be seen that this embodiment provides a refrigerator contact switch assembly, which is composed of Figure 2 and Figure 4 It can be seen that the switch assembly provided in this embodiment is respectively arranged on the refrigerator door and the refrigerator body, and the switch assembly includes:

[0056] The base body 100 is arranged on the refrigerator body, and the base body 100 is connected to the control panel of the refrigerator by a wiring harness.

[0057] Specifically, in the present embodiment, the base body 100 is disposed in a refrigerator body of the refrigerator. When the refrigerator is assembled, the base body 100 is connected to the control board of the refrigerator through a wiring harness.

[0058] It should be noted that the conventional wiring harness setting method is to connect the refrigerator body and the refrigerator door through the refrigerator hinges and related components, while the refrigerator wiring harness in this embodiment does not have a physical wiring harness connection between the refrigerator body and the refrigerator door, that is, the base body 100 is only connected to the control panel wiring harness located on the refrigerator body, and has no wiring harness connection with the related components located on the refrigerator door.

[0059] In order to facilitate understanding of the role of the wiring harness in the refrigerator, the following introduces the specific situation of the wiring harness between the door and the cabinet of a conventional refrigerator:

[0060] The wiring harness between the refrigerator door and the cabinet plays a vital role. These wiring harnesses serve as an important bridge connecting various sensors, controllers, lighting equipment on the door and the power supply and control system inside the cabinet, ensuring the normal operation of various functions of the refrigerator.

[0061] Specifically, the refrigerator door is usually equipped with devices such as temperature sensors, defrost heaters, door switch sensors, and LED lights. These devices need to communicate and transmit data with the control system inside the box through the wiring harness. The wiring harness contains multiple finely arranged wires, each of which has a specific signal transmission or power supply task. For example, the temperature sensor transmits the temperature information inside the door to the control system in real time through the wiring harness, and the control system adjusts the operating status of the refrigeration system based on this information to keep the temperature inside the refrigerator constant.

[0062] When designing the wiring harness, several technical factors need to be considered to ensure its reliability and durability. First, the wiring harness needs to have good flexibility to adapt to the bending and stretching caused by the frequent opening and closing of the refrigerator door. Secondly, the outer sheath material of the wiring harness needs to have excellent wear resistance, oil resistance and chemical corrosion resistance to prevent the insulation layer from being damaged or the wires from aging due to environmental factors during long-term use. In addition, the layout and fixing method of the wiring harness also need to be carefully designed to avoid vibration or noise during the operation of the refrigerator.

[0063] With the continuous development of smart home technology, modern refrigerators tend to integrate more intelligent functions. This requires the wiring harness between the refrigerator door and the cabinet to not only meet the basic signal transmission and power supply requirements, but also support high-speed data transmission and complex communication protocols. Therefore, in the design and manufacturing process of the wiring harness, more advanced technologies and materials need to be adopted to meet the needs of the intelligent development of refrigerators.

[0064] The switch assembly further comprises:

[0065] The extension body 200 is arranged on the refrigerator door body, and the extension body 200 is connected to the display panel of the refrigerator by a wiring harness.

[0066] Specifically, in the present embodiment, the protrusion 200 is disposed in the door of the refrigerator, and when the refrigerator is assembled, the protrusion 200 is connected to the display panel of the refrigerator via a wiring harness.

[0067] It should be noted that the protruding body 200 in this embodiment is only connected to the display panel wiring harness located on the refrigerator door, and is not connected to the related components located on the refrigerator body by wiring harness.

[0068] Based on the above description of the base body 100 and the extension body 200, it can be known that there is no physical wiring harness connection between the base body 100 and the extension body 200, but when the refrigerator is closed, the contact parts in the base body 100 and the extension body 200 must be in contact, so as to achieve a contact switch effect, that is, when the refrigerator door body is in contact with the refrigerator body, the base body 100 is in contact with the extension body 200, and a passage is formed between the control panel and the display panel.

[0069] By independently arranging the base body 100 and the extension body 200, the problem of arranging a wiring harness in a refrigerator hinge, which results in the wiring harness being limited by the size of the installation hole, is avoided.

[0076] The base 130 is disposed in the base box 120 , the base 130 can be contact-connected to the extension 200 , and the base 130 is connected to the control board harness.

[0077] Specifically, in the present embodiment, the base 130 is used to form a passage with the protruding body 200, so the base 130 can be understood as a "switch" in the base body 100. If such a "switch" structure is directly set in the refrigerator body, the circuit may be affected by unnecessary factors. Therefore, the present embodiment also provides the base box 120, and the base 130 is set in the base box 120 to complete the storage of the base box 120, and the base box 120 is clamped on the box beam 110, thereby realizing the placement of the base body 100 on the refrigerator body.

[0082] A fixing box 220, wherein the fixing box 220 is connected to the door trim 210;

[0083] A spring tongue piece 230, wherein the spring tongue piece 230 is connected to the fixed box 220, the spring tongue piece 230 is connected to the display panel wiring harness, a part of the structure of the spring tongue piece 230 is arranged in the fixed box 220, and the spring tongue piece 230 extends out of the fixed box 220; the spring tongue piece 230 corresponds to the base 130 one by one, and when the refrigerator door is in contact with the refrigerator body, the extended part of the spring tongue piece 230 is in contact with the base 130, and a passage is formed between the display panel and the control panel.

[0084] Specifically, in the present embodiment, the spring tongue piece 230 is used to form a passage with the base body 100, so the spring tongue piece 230 can be understood as a "switch" in the protruding body 200. If the spring tongue piece 230 is directly set in the refrigerator door body, the wiring harness will also be affected by unnecessary factors. Therefore, the present embodiment also provides the fixing box 220, and the fixing box 220 plays a similar role to the base box 120. The spring tongue piece 230 is set in the fixing box 220 to complete the storage of the spring tongue piece 230, and the fixing box 220 is snapped onto the refrigerator door body, thereby realizing the placement of the protruding body on the refrigerator door body.

[0090] Specifically, in this embodiment, the claw 121 is used to clamp with the box beam 110, and the base body 100 is fixed to the refrigerator body through the claw 121; the first wire threading hole 122 is used to provide a wire harness passage space for the wire harness connected to the base body 100, and the wire harness extends out of the base body 100 through the first wire threading hole 122 and is connected to the control board.

[0091] Furthermore, in some embodiments, the base box 120 further includes:

[0092] Elastic claws 123 and clamping bodies 124 are provided on opposite sides of the base box 120 connected to the box beam 110 .

[0093] Specifically, in this embodiment, the elastic claws 123 and the clamping body 124 are provided on both sides of the base box 120, and the elastic claws 123 and the clamping body 124 on each side form a group. The box beam 110 is clamped by such a group of structures, thereby further improving the fixed relationship between the base body 100 and the refrigerator body.

[0094] Furthermore, in some embodiments, the box beam 110 includes:

[0095] An L-shaped bending portion 111, wherein a first mounting hole 1110 is provided on the L-shaped bending portion 111, and the clamping claw 121 is clamped with the first mounting hole 1110;

[0098] The base mounting hole 112 is used to provide a clamping point for the elastic claw 123 and the clamping body 124. Through the elastic deformation property of the elastic claw 123, the base mounting hole 112 is clamped between the elastic claw 123 and the clamping body 124, thereby completing the clamping of the entire structure between the box beam 110 and the base box 120.

[0099] Furthermore, in some embodiments, the base 130 includes:

[0100] A contact portion 131, the contact portion 131 extends out of the base box 120; when the refrigerator door is in contact with the refrigerator body, the contact portion 131 is in contact with the elastic tongue piece 230;

[0101] The first connecting portion 132 is connected to the control board wiring harness; the contact portion 131 and the first connecting portion 132 are both made of good conductor material.

[0102] Specifically, in this embodiment, the contact portion 131 is used to directly contact the spring tongue piece 230 and form a passage. It can be understood that the contact portion 131 is the "switch connector" in the base body 100, that is, the "switch connector". The contact portion 131 needs to extend out of the base box 120 so that it can contact the spring tongue piece 230 more effectively.

[0103] The first connection portion 132 is the rear half of the base 130 . The first connection portion 132 is mainly used to connect with the wiring harness, and thereby achieve connection with the control board.

[0104] Since the contact portion 131 and the first connecting portion 132 are necessary structures for forming a passage, the materials used to make the contact portion 131 and the first connecting portion 132 are both good conductor materials that are moisture-proof and corrosion-resistant.

[0105] Furthermore, in some embodiments, the fixing box 220 includes:

[0106] A second mounting hole 221, wherein the second mounting hole 221 is disposed at the bottom of the fixing box 220;

[0107] A plurality of openings 222, wherein the openings 222 correspond to the elastic tongue pieces 230 one by one, and the elastic tongue pieces 230 extend out of the fixing box 220 through the openings 222;

[0108] A plurality of groups of fixing ribs 223 are disposed inside the fixing box 220 .
