Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and more particularly to a refrigeration equipment with an anti-static device. Background Technology

[0002] During the use of refrigeration equipment, induced currents often accumulate on the door surface, causing users to experience an electric shock when touching the door. Furthermore, these induced currents pose a risk of electrostatic discharge (ESD) to the door's display panel. To address these issues, existing technology involves placing a wire inside the door housing and securing it to the housing with tape, with one end of the wire connected to the casing for conductivity. However, this method is complex, requiring assembly at multiple stations. Additionally, during the door foaming process, the foaming material can impact the wire, potentially causing grounding failure. Summary of the Invention

[0003] The purpose of this invention is to provide a refrigeration device that connects the door shell to the hinge shaft through an anti-static device and then uses the housing for electrical conduction, thus avoiding the problem in the prior art where the wires are impacted by the foam material, causing the door shell and housing to fail to connect and resulting in grounding failure.

[0004] To achieve one of the aforementioned objectives, one embodiment of the present invention provides a refrigeration device, comprising: a housing; a door, including a door shell and a decorative strip connected to the bottom of the door shell, the decorative strip extending into the door to form a shaft hole; a hinge assembly, including a hinge plate fixed to the housing and a hinge shaft disposed in the shaft hole, the housing and the door being rotatably connected by the hinge assembly; and an anti-static device, one end of which is fixed to the decorative strip, the anti-static device abutting against the door shell and the hinge shaft respectively, so that the induced current generated by the door is transmitted to the hinge shaft through the anti-static device, and then transmitted to the housing through the hinge shaft, thereby using the housing to conduct the induced current generated by the door to the ground.

[0005] As a further improvement of one embodiment of the present invention, the anti-static device includes a conductive element fixed to the trim strip and abutting against the door shell, and an elastic component abutting against one end of the conductive element, wherein the end of the elastic component away from the conductive element abuts against the hinge shaft.

[0006] As a further improvement of one embodiment of the present invention, the elastic component includes a connector and an elastic member that abut against each other, one end of the elastic member abutting against the conductive member, and the end of the connector away from the elastic member abutting against the hinge shaft.

[0007] As a further improvement of one embodiment of the present invention, the hinge assembly further includes a bushing, the bushing including a sleeve extending into the shaft hole, and the elastic element, the connecting element, and the hinge shaft are sequentially disposed inside the sleeve.

[0008] As a further improvement of one embodiment of the present invention, the connector extends outward to form a first protrusion, the bushing has a first through hole at one end near the conductive element, the connector passes through the first through hole and abuts against the hinge shaft, and the first protrusion abuts against the outer edge of the first through hole near the elastic element.

[0009] As a further improvement of one embodiment of the present invention, the conductive member includes a body fixedly connected to the trim strip, a first abutting portion extending from the body toward the door shell and abutting against the door shell, and a second abutting portion extending from the body toward the elastic member and abutting against the elastic member.

[0010] As a further improvement of one embodiment of the present invention, the first abutting part is Z-shaped. The Z-shaped first abutting part includes a first protruding surface connected to the main body, a connecting surface connected to the end of the first protruding surface away from the main body, and a first abutting surface connected to the end of the connecting surface away from the first protruding surface. The first abutting surface abuts against the door shell.

[0011] As a further improvement of one embodiment of the present invention, the second abutting part is L-shaped. The L-shaped second abutting part includes a second protruding surface connected to the body and a second abutting surface connected to the end of the second protruding surface away from the body. The second abutting surface abuts against the elastic member.

[0012] As a further improvement of one embodiment of the present invention, the bushing further includes a fixing part, which is connected to the end of the sleeve away from the elastic member, and the fixing part is fixedly connected to the trim strip.

[0013] As a further improvement of one embodiment of the present invention, the hinge plate is provided with a second through hole, the hinge axis extends outward to form a second protrusion, and the hinge axis passes through the second through hole so that the second protrusion abuts against the outer edge of the second through hole near the side of the power dissipation device.

[0014] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0015] This invention utilizes an anti-static device fixedly connected to the door body to connect the door shell to the hinge shaft. The anti-static device abuts against both the door shell and the hinge shaft, guiding the induced current on the door shell from the anti-static device to the hinge shaft, and further guiding the induced current to the hinge plate connected to the housing. The induced current generated on the door shell is then conducted to the ground using the housing's grounding wire. The fixed connection between the anti-static device and the door body prevents the foaming material from impacting the anti-static device during door foaming, thus avoiding grounding failure due to poor contact.

However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0023] The terms used herein, such as “above,” “over,” “below,” and “under,” indicating spatial relative position, are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. These terms may be intended to include different orientations of the device in use or operation other than those shown in the figures. For example, if the device in the figures is flipped, a unit described as being “below” or “under” another unit or feature would be “above” that unit or feature. Therefore, the exemplary term “below” can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or otherwise), and the spatially related descriptive terms used herein will be interpreted accordingly.

[0024] Furthermore, it should be understood that although the terms "first," "second," etc., may be used herein to describe various elements or structures, the objects being described should not be limited by these terms. These terms are only used to distinguish these objects from one another. For example, a first through hole may be referred to as a second through hole, and similarly, a second through hole may be referred to as a first through hole, without departing from the scope of protection of this application.

[0025] Embodiment 1 of the present invention provides a refrigeration device, such as Figure 1-4 As shown, the device includes a housing 1, a door 2, a hinge assembly 3 connecting the housing 1 and the door 2, and a current-eliminating device for eliminating induced current. The door 2 includes a door shell 21 and a decorative strip 22 connected to the bottom of the door shell 21. The decorative strip 22 extends into the door 2 to form a shaft hole 221. The hinge assembly 3 includes a hinge plate 31 fixed to the housing 1 and a hinge shaft 32 disposed within the shaft hole 221. The housing 1 and the door 2 are rotatably connected via the hinge assembly 3. One end of the current-eliminating device is fixed to the decorative strip 22. The current-eliminating device abuts against both the door shell 21 and the hinge shaft 32, so that the induced current generated by the door 2 is transmitted through the current-eliminating device to the hinge shaft 32, and then through the hinge shaft 32 to the housing 1. The housing 1 then conducts the induced current generated by the door 2 to the ground.

[0026] In this embodiment, a current-eliminating device fixedly connected to the door body 2 connects the door shell 21 to the hinge shaft 32. The current-eliminating device abuts against both the door shell 21 and the hinge shaft 32, guiding the induced current on the door shell 21 from the current-eliminating device to the hinge shaft 32, and further guiding the induced current to the hinge plate 31 connected to the housing 1. The grounding wire of the housing 1 then conducts the induced current generated on the door shell 21 into the ground. The fixed connection between the current-eliminating device and the door body 2 in this invention can prevent the foaming material from impacting the current-eliminating device during the foaming of the door body 2, and avoid grounding failure caused by poor contact.

[0027] Specifically, the anti-static device includes a conductive element 4 fixed to the trim strip 22 and abutting against the door shell 21, and an elastic component abutting against one end of the conductive element 4. The elastic component includes an elastic element 5 and a connecting element 6 that abut against each other and respectively abut against the conductive element 4 and the hinge shaft 32.

[0028] like Figure 5 As shown, the conductive component 4 includes a body 41, a first abutting part 42, and a second abutting part 43. The body 41 is fixedly connected to the trim strip 22 by screws to ensure the stability of the conductive component 4. This can prevent the foaming material from impacting the conductive component 4 during the foaming of the door body 2, which would prevent the conductive component 4 from having a conductive effect and thus cause grounding failure.

[0029] In this embodiment, the first abutting portion 42 is Z-shaped and extends from the body 41 toward the door shell 21. The Z-shaped first abutting portion 42 includes a first protruding surface 421 connected to the body 41, a connecting surface 422 connected to the end of the first protruding surface 421 away from the body 41, and a first abutting surface 423 connected to the end of the connecting surface 422 away from the first protruding surface 421. The first abutting surface 423 abuts against the door shell 21 with its larger surface area. The first protruding surface 421 is perpendicular to the body 41, the connecting surface 422 is perpendicular to the first protruding surface 421, and the first abutting surface 423 is perpendicular to the connecting surface 422. Thus, the first abutting surface 423 can abut against the door shell 21 with its larger surface area, making it easier for current to flow from the door shell 21 to the conductive element 4. Of course, the present invention is not limited to the first abutting portion 42 being Z-shaped; the first abutting portion 42 can also extend from the body 41 to abut against the door shell 21 in any other form.

[0030] The second abutment portion 43 is L-shaped and extends from the body 41 toward the elastic member 5. The L-shaped second abutment portion 43 includes a second protruding surface 431 connected to the body 41 and a second abutment surface 432 connected to the end of the second protruding surface 431 away from the body 41. The second abutment surface 432 abuts against the elastic member 5. The second protruding surface 431 is perpendicular to the body 41, and the second abutment surface 432 is perpendicular to the second protruding surface 431. Thus, the second abutment surface 432 is horizontally arranged, which can prevent poor contact between the second abutment surface 432 and the elastic member 5 when the second abutment surface 432 is tilted, and the elastic member 5 slips off the second abutment surface 432 due to the elastic force of the elastic member 5, resulting in poor grounding effect of the door body 2. Of course, the present invention is not limited to the second abutment portion 43 being L-shaped; the second abutment portion 43 can also extend from the body 41 to abut against the elastic member 5 in any other form.

[0031] The hinge assembly 3 also includes a bushing 33, which includes a sleeve 331 extending into the shaft hole 221 and a fixing part 332 connected to the end of the sleeve 331 away from the elastic member 5. The elastic member 5, the connecting member 6, and the hinge shaft 32 are sequentially arranged inside the sleeve 331. The fixing part 332 is fixedly connected to the trim strip 22 to fix the bushing 33, and the positions of the elastic member 5, the connecting member 6, and the hinge shaft 32 inside the bushing 33 are fixed. Preferably, the bushing 33 is made of plastic, so the sleeve 331 can reduce the friction between the hinge shaft 32 and the hinge plate 31.

[0032] Furthermore, the connector 6 extends outward to form a first protrusion 61, and a first through hole 3311 is formed at the end of the sleeve 331 near the conductive member 4. The connector 6 passes through the first through hole 3311 from the end of the sleeve 331 near the conductive member 4 and abuts against the hinge shaft 32. The first protrusion 61 abuts against the outer edge of the first through hole 3311 near the elastic member 5. The cooperation of the first protrusion 61, the first through hole 3311 and the elastic member 5 can fix the connector 6 and the elastic member 5 in the sleeve 331. This can prevent the poor stability of the connector 6 and the elastic member 5 in the sleeve 331 from causing no contact between the conductive member 4 and the hinge shaft 32. As a result, the induced current generated on the door shell 21 cannot be transmitted to the hinge shaft 32 through the conductive member 4 and thus to the hinge plate 31. Instead, it is led to the ground by the grounding wire of the housing 1.

[0033] Furthermore, the hinge plate 31 is provided with a second through hole 311, and the hinge shaft 32 extends outward to form a second protrusion 321. The hinge shaft 32 passes through the second through hole 311 from the side of the hinge plate 31 near the power elimination device. The second protrusion 321 abuts against the outer edge of the second through hole 311 near the power elimination device to prevent the hinge shaft 32 from slipping out of the second through hole 311.

[0034] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
