Technical Field

[0003] This application relates to the field of refrigeration equipment technology, specifically to a refrigeration device and storage device with interchangeable left and right doors and equipped with a sound-emitting element. Background Technology

[0004] Single-door refrigeration devices, such as wine cabinets or refrigerators, are equipped with speakers or horns for voice interaction. With continuous development, for single-door wine cabinets, to meet users' needs for different door opening directions, users require the door to be interchangeable left or right. However, in the structure of wine cabinets with all-glass doors that allow for left-right interchangeability, it is impossible to install speakers. This is mainly because the wine cabinet door is made of a single piece of glass or other solid material; if a speaker needs to be installed, it is impossible to drill holes in the front surface of the door, making it impossible to install speakers or horns from the front, thus failing to meet the actual needs of users.

A notch is formed at the bottom of the connector mounting cover 310, and when the connector mounting cover 310 is snapped onto the mounting portion 221, a connector insertion space is formed between the bottom notch and the bottom of the mounting portion. Referring to Figure 6, a mounting position 2211 is provided at the bottom of the mounting portion 221, and the connector 121 can extend into the connector insertion space and be inserted into the mounting position 2211 via a connector shaft. Correspondingly, a connecting decorative cover 320 can be fitted at another mounting portion 221. The connecting decorative cover 320 is detachably fitted onto the mounting portion 221, and can also be snapped onto the mounting portion 221 for easy disassembly and installation. The connecting decorative cover 320 can cover the mounting portion 221 exposed on the outside.

[0132] When the refrigeration equipment opens to the right, the connector mounting cover 310 and the connector decorative cover 320 are respectively installed at the two mounting portions 221. The connector mounting cover 310 is installed on the right side and is called the right connector mounting cover, while the connector decorative cover 320 is installed on the left side and is called the left connector decorative cover. When the refrigeration equipment needs to open to the right, the connector 121 of the door body 200 needs to be replaced. If the refrigeration equipment is designed to open to the left at the factory, an assembly position, i.e., a connector assembly hole, is reserved on the right side of the cabinet 100. That is, assembly positions are provided on both the left and right sides of the cabinet 100, and the door body 200 can be connected to either of these assembly positions via the connector 121.

[0133] Mounting positions 2211 are also provided at the mounting portions 221 on the left and right sides of the door 200, so that the connector can be installed on the left or right side of the cabinet 100 during installation, realizing the interchangeability of left and right opening doors. When interchangeding the door 200, first disassemble the connector 121 on the left side of the refrigeration equipment to separate the door 200 from the cabinet 100. Then, remove the connector mounting cover 310 and the connecting decorative cover 320. Install the connector on the right side of the cabinet 100 to achieve right-opening door. After the connector is installed, reinstall the connector mounting cover 310 and the connecting decorative cover 320 to cover the mounting portion 221. Similarly, if a left-opening door is required again, the connector can be disassembled and connected to the left side of the cabinet 100, realizing the interchangeable installation of the left and right doors 200 of the refrigeration equipment. The refrigeration equipment has interchangeable left and right doors for the entire door 200 panel by setting assembly holes for connectors on both sides of the cabinet 100, setting an upper cover component 220 on the inside of the door panel 210, and setting mounting positions 2211 at the mounting parts 221 at both ends of the upper cover component 220. This satisfies the installation and use requirements of the door 200 being interchangeable between the left and right sides.

[0134] In some embodiments, when the connector 121 is a hinge, the assembly position 120 is a hinge assembly part, the mounting position 2211 is a hinge mounting part, the connector mounting cover 310 is a hinge mounting cover, the connector decorative cover 320 is a hinge decorative cover, the connector mounting cover 310 is a hinge mounting cover, and the connector assembly hole is a hinge assembly hole. In some embodiments, the connector can be a slide rail, a snap-fit ​​structure, a magnetic connector, an elastic snap, or a bolt fastener, etc. Accordingly, the assembly position 120 can be a slide rail assembly part, which is a groove or guide rail structure for installing the slide rail connector to facilitate the sliding opening and closing of the door; a magnetic assembly part, which embeds magnetic material or a magnetic adsorption groove for installing the magnetic connector; a bolt assembly part, which adds bolt mounting holes for the mating connection of the bolt fastener; or a snap-fit ​​assembly part, which reserves plastic or metal snap-fit ​​slots to ensure that the connector can be quickly snapped in.

The connector decorative cover 320 can be a slide rail decorative cover, concealing the slide rail interface and keeping the refrigeration equipment looking clean; a magnetic decorative cover, a smooth decorative piece that mates with the magnetic mounting part, preventing dust or foreign objects from entering; a flexible snap-on decorative cover, a bendable decorative cover that fits the snap-on area, enhancing protection; or a bolt decorative cover, a decorative component covering the bolt connection area, providing rust prevention. The connector mounting holes can be slide rail mounting holes, designed as elongated slots for slide rail positioning and installation; magnetic mounting holes, such as circular or rectangular holes, adapted for magnetic components or adsorption devices; snap-on mounting holes, pre-drilled fixing holes for snap-on connectors, providing a certain degree of flexibility; or bolt mounting holes, with standard bolt hole diameters, compatible with various bolt specifications, enhancing versatility.

[0135] In some embodiments of this application, referring to FIG7, the door frame component includes:

[0136] The left door frame 230 is vertically fitted to the left side of the door panel 210 and is formed by direct extrusion of profiles.

[0137] The right door frame is 240mm, vertically aligned with the right side of the proportional door panel, and is also directly formed by profile extrusion.

[0138] The lower end cover, positioned opposite the upper end cover, is fixedly connected at its two ends to the bottom of the left door frame 230 and the right door frame 240, respectively, while fitting snugly against the bottom of the door panel 210. The upper end cover component 220 is inserted between the left door frame 230 and the right door frame 240, and its two ends are fixedly connected to the top of the left door frame 230 and the right door frame 240 by reinforcing members. To achieve a tight fit between the upper end cover component 220 and the left door frame 230 and the right door frame 240, the cross-sectional shape of its two sides is designed to match the cross-sectional shape of the left door frame 230 and the right door frame 240, ensuring a tight fit among the three components.

[0139] In some embodiments of this application, a frame is formed between the left door frame 230, the right door frame 240, the upper end cover component 220, and the lower end cover, forming a hollow space inside. A first folded edge 231 extending into the hollow space is formed on the left door frame 230, a second folded edge 232 extending into the hollow space is formed on the right door frame 240, and a third folded edge is formed on the upper end cover component 220.

[0140] In some embodiments of this application, referring to Figures 7 and 10, the door 200 further includes an inner panel 270, which is fitted to the first folded edge, the second folded edge, and the third folded edge. A support frame is provided above the inner panel, surrounding the hollow space, and the outer side of the support frame is flush with the outer sides of the left door frame 230, the right door frame 240, and the upper end cover component 220.

[0141] Referring to Figures 2 and 8, the upper end cover component 220 forms a speaker mounting area 260 between the two mounting portions 221. The speaker mounting area 260 can be used to assemble the speaker 400 and the corresponding connecting wire 500. In some embodiments, a speaker mounting space 261 and a wire receiving channel 262 are formed in the speaker mounting area 260; the speaker 400 is mounted in the speaker mounting space 261, and the speaker 400 is accommodated and assembled by the speaker mounting space 261 formed in the speaker mounting area 260.

[0142] In some embodiments of this application, the sound-producing element 400 is a loudspeaker or horn. Referring to Figures 2 and 15, a wire 500 is connected to the sound-producing element 400. When the wire 500 is connected, one end is connected to the sound-producing element 400, and the other end is connected to the main control board inside the housing 100, so that the sound-producing element 400 can be controlled through the main control board.

[0143] The wire 500 is at least partially disposed within the wire receiving channel 262 and can extend along the width direction of the upper end cover toward the mounting portion 221 at either end. The wire 500 is partially positioned within the guide receiving space, and the wire receiving channel 262 accommodates and supports the wire 500, ensuring its positioning and preventing it from falling out or moving within the channel. The portion of the wire 500 within the wire receiving channel 262 will not move. The wire 500 has a free section that can extend along the width direction of the upper end cover component 220 toward the mounting portion 221 at either end, allowing it to adapt to left-opening or right-opening door configurations.

[0144] If the refrigeration device has a left-opening door, the free section of the wire 500 can extend to the left side of the enclosure 100 to connect with the main control board in the enclosure 100; if the refrigeration device has a right-opening door, the free section of the wire 500 can be bent and extended to the right side of the enclosure 100 to connect with the main control board in the enclosure 100. The refrigeration device arranges the sound-emitting element mounting area 260 between the mounting portions 221 at both ends of the upper cover component 220, so that the sound-emitting element mounting area 260 is located in the middle area of ​​the upper cover component 220.

[0145] When the door body 200 is interchanged, it is only necessary to use the mounting position 2211 at the corresponding connection end of the connector. In this way, regardless of whether the door body 200 is a left-opening or right-opening door, the speaker mounting area 260 is always kept in the middle position, the speaker 400 is also always in the middle position, and the wire 500 is also basically in the middle position. After the door body 200 is interchanged, there is no need to disassemble the speaker 400. It is only necessary to adjust the bending extension direction of the free section of the wire 500. There is no need to completely disassemble and reconnect the wire 500. While ensuring that the left and right doors can be interchanged, the speaker 400 can be used without disassembly, which is convenient for users to interchange the left and right doors and to interact with the voice, thus meeting the user's needs.

[0146] In some embodiments of this application, referring to Figures 3 and 6, two sound-emitting element mounting spaces 261 are formed, respectively arranged near the two mounting portions 221, that is, both sound-emitting element mounting spaces 261 are arranged adjacent to the two mounting portions 221. Two sound-emitting elements 400 are provided, respectively assembled within the sound-emitting element mounting spaces 261; by providing two sound-emitting elements 400 and arranging them respectively within the two sound-emitting element mounting spaces 261 near both ends of the upper cover, clear sound production and improved sound quality are ensured. Furthermore, by simultaneously providing two sound-emitting elements 400, sound can be emitted to both sides, resulting in a wide sound range. The wire receiving channel 262 includes a first wire channel 2621 arranged between the two sound-emitting elements 400; the first wire channel 2621 is a transverse space, arranged between the two sound-emitting element mounting spaces 261. And a vertically arranged second conductor channel 2622, which is connected to the first conductor channel 2621 and is located at the middle position of the first conductor channel 2621, is used to reverse the direction of the conductor 500.

[0147] Referring to Figures 14 and 15, the wire 500 includes a branch wire 510 disposed within a first wire channel 2621, with both ends connected to two sound-producing elements 400 respectively; and a main wire 520 connected to the branch wire 510 disposed within a second wire channel 2622, having a free end that extends optionally to one end of the upper end cap after exiting the second wire channel 2622.

[0148] The two sound-emitting elements 400 located at both ends are connected by a horizontally arranged branch wire 510. The main wire 520 is connected to the branch wire 510 and extends downward along the second wire channel 2622. After exiting the second wire channel 2622, the main wire 520 can extend to the left or right depending on the actual structure of the left-opening or right-opening door. Since the two sound-emitting elements 400 are located in the middle area between the two mounting parts 221, even if the door body 200 is interchanged, the two sound-emitting elements 400 do not need to be reinstalled; only the bending direction of the main wire 520 needs to be adjusted.

[0149] In some embodiments of this application, a single sound-emitting element mounting space 261 is formed and arranged adjacent to one of the mounting portions 221; a single sound-emitting element 400 is provided and assembled within the sound-emitting element mounting space 261; a wire receiving channel 262 includes a horizontally arranged first wire channel 2621 and a vertically arranged second wire channel 2622; one end of a wire 500 is connected to the sound-emitting element 400, and the other end extends from the first wire channel 2621 into the second wire channel 2622 and extends from the second wire channel 2622 to one end of the upper end cover. In other words, during setup, only one speaker 400 can be set up, forming a speaker installation space 261 at the upper cover component 220. It can be set near either installation part 221, and the speaker 400 can still make sounds. The speaker 400 is also located in the area between the two installation parts 221. After the door body 200 is interchanged, there is no need to change the installation and assembly position of the speaker 400, ensuring the normal use of the speaker 400 after the door body 200 is interchanged.

[0150] In some embodiments, the speaker mounting space 261 can be designed as a detachable module, allowing for the replacement of different specifications or types of speakers (such as tweeters and woofers) according to user needs. The module employs a snap-fit ​​or sliding rail structure for easy and quick installation, removal, and maintenance. Flexible brackets or telescopic components can be added within the speaker mounting space 261 to accommodate speakers of different sizes. The brackets have shock-absorbing capabilities, reducing vibration noise during device operation. Adding sound-absorbing material to the inner wall or a sound wave guiding design improves sound propagation quality. The design features a horn-shaped expansion cavity to enhance the volume and clarity of the speaker output. Temperature and humidity sensors or ambient light sensors can be integrated within the speaker mounting space 261 to provide intelligent feedback in conjunction with the voice system. Adding ventilation holes extends the lifespan of the speaker. In addition to the top mounting, additional mounting spaces can be added to the side or bottom areas to achieve multi-dimensional sound effects. In large-size doors, multiple mounting spaces can form an array layout to enhance sound field coverage. The speaker 400 housing can be equipped with RGB lighting, supporting scene modes (such as voice interaction and music rhythm lighting effects). Lights can be used to indicate device status (such as switch status or fault indication). The wire accommodating channel 262 can be designed as a multi-zone system to support the placement of additional wires or functional components (such as sensor wiring), improving compatibility. Zones are equipped with quick connectors for easy wiring replacement or upgrades.

[0190] To further optimize the functional design and user experience of refrigeration equipment, and in conjunction with the technical features described in the preceding embodiments, the following embodiments improve the speaker installation and sound output methods. By providing mounting slots and sound transmission holes on the back of the cabinet door, not only is concealed installation of the speaker and efficient sound output achieved, but the structural strength reduction that might result from opening holes in the door panel is also avoided. This allows the storage device to maintain a clean and integrated appearance while also meeting the requirements for high-quality sound output. The following will describe in detail some embodiments of this optimized design in storage devices such as wine cabinets and refrigerators.

[0191] With the rapid development of home furnishing, storage devices such as wine cabinets and refrigerators require speakers installed on the doors to enable voice interaction or prompts. Some wine cabinets and refrigerators use interchangeable left and right doors with hinges that allow for left- or right-opening. Therefore, a storage device with a speaker is needed to meet the diverse usage needs of left- or right-opening doors. Additionally, the doors of wine cabinets and other storage devices in related technologies are typically made of glass, providing visibility, but the glass surface is not suitable for opening holes. Therefore, a storage device with a speaker is needed to meet the sound output requirements. The following describes in detail some embodiments of the storage device using a wine cabinet as an example. For ease of description, unless otherwise specified, the directions of up, down, left, right, front, and back are based on the state of the wine cabinet in use. The front of the wine cabinet door is considered the front, the opposite direction is the back, the vertical direction is up-down, and the horizontal direction is left-right.
