[0033] With the development of technology, refrigeration equipment such as refrigerators and freezers have become indispensable appliances in modern homes, and their stable operation is crucial for food preservation and user experience. However, during long-term use, the water vapor generated by the evaporator during periodic defrosting condenses on the terminal components 500 of the equipment, causing oxidation and corrosion of metal parts. This problem increases contact resistance and may even cause abnormal signal transmission or circuit breaks, thus affecting the normal operation of the refrigeration system, such as temperature control failure or unexpected shutdown, reducing equipment reliability and increasing maintenance costs.

[0034] Related technologies employ simple sealing methods such as rubber sleeves or plastic caps, application of rust-preventive oil or ordinary plating, and passive drainage via drainage channels. However, these methods have significant limitations: sealing materials are prone to aging and failure, rust-preventive coatings lack durability in high-temperature and high-humidity environments, and passive drainage cannot completely prevent moisture retention. Therefore, this application proposes a refrigeration device that addresses the defect of moisture generated during the periodic defrosting of the evaporator entering the interior of the terminal assembly 500.

[0035] The following is combined with Figures 1 to 10 Describe the refrigeration equipment of this application.

[0036] Please refer to the refrigeration equipment proposed in the embodiments of this application. Figures 1 to 3 The refrigeration equipment includes a housing 100, an air duct assembly 200, an air supply assembly 300, a first liner 400, and a terminal assembly 500. The housing 100 has an internal cavity 101. The air duct assembly 200 is vertically installed in the cavity 101 and has an air supply channel 201. The air supply assembly 300 is installed in the air duct assembly 200, and at least partially located within the air supply channel 201. The first liner 400 is installed in the cavity 101 and has a first refrigeration compartment 410 and a second refrigeration compartment 420. The first refrigeration compartment 410 is located on the first side of the air duct assembly 200, and the second refrigeration compartment 420 is located on the second side of the air duct assembly 200. The air supply duct 201 connects the first refrigeration compartment 410 and the second refrigeration compartment 420. The air duct assembly 200 is provided with a connecting part 220, which extends vertically and protrudes from the top of the first box liner 400. The terminal assembly 500 is installed on the outside of the connecting part 220. The terminal assembly 500 is spatially isolated from the air supply duct 201 and is not connected. The terminal assembly 500 is used to connect to the bus harness.

[0037] According to the refrigeration equipment of the present application embodiment, the terminal assembly 500 is spatially isolated from and not connected to the air supply channel 201, which can effectively prevent water vapor generated by the periodic defrosting of the evaporator from entering the interior of the terminal assembly 500, thereby improving the service life of the refrigeration equipment.

[0038] It is understood that the housing 100 is the outer shell structure of the refrigeration equipment, with an internal cavity 101 for accommodating other components. The air duct assembly 200 is vertically installed within the cavity 101, and the first inner liner 400 is installed within the cavity 101. The cavity is internally divided into a first refrigeration compartment 410 and a second refrigeration compartment 420, located on either side of the air duct assembly 200. The air supply duct 201 connects the first refrigeration compartment 410 and the second refrigeration compartment 420 to achieve cold air distribution. The first refrigeration compartment 410 can be either a refrigerator compartment or a freezer compartment, and the second refrigeration compartment 420 can also be either a refrigerator compartment or a freezer compartment. The air supply assembly 300 is installed within the air supply duct 201 to drive the circulation of cold air within the refrigeration compartments.

[0039] The air duct assembly 200 is provided with a connecting part 220, which extends vertically and protrudes from the top of the first housing 400 to form an independent installation area. The terminal assembly 500 is installed on the outside of the connecting part 220 of the air duct assembly 200 for plugging into an external bus bundle (power line or signal line collection) and for supplying power or transmitting control signals to the air supply assembly 300.

[0040] Understandably, the terminal assembly 500 is structurally completely isolated from and not connected to the air supply duct 201, preventing defrosting moisture from directly contacting the terminals through the air duct. In traditional designs, the terminal assembly 500 is often located inside the air supply duct 201, where water vapor generated during evaporator defrosting easily condenses on the metal surface of the terminals, leading to corrosion. In this application, the terminal assembly 500 is installed outside the connection portion 220, avoiding communication with the air supply duct 201. Through physical isolation, the path for moisture intrusion is fundamentally blocked.

[0041] In one embodiment, the evaporator is located within the first air duct assembly 210 below the connection portion 220. It is understood that the terminal assembly 500 is located outside the connection portion 220, away from the defrost water concentration area (such as the bottom of the evaporator). The high-mounted terminal assembly 500 further reduces the probability of water vapor adhesion and facilitates the wiring arrangement of the bus harness.

[0042] It should be noted that the first liner 400 of this application is internally divided into a first refrigeration compartment 410 and a second refrigeration compartment 420, which can be implemented in two ways. The first way is to use a one-piece molded box structure, with the liner divided into the first refrigeration compartment 410 and the second refrigeration compartment 420 by an internal air duct assembly 200. The second way is to use a split design, where the first liner consists of two independent smaller liners. One smaller liner is located on the first side of the air duct assembly 200 and forms the first refrigeration compartment 410, while the other smaller liner is located on the second side of the air duct assembly and forms the second refrigeration compartment 420. These two structural designs can be flexibly selected according to actual needs to meet different refrigeration space layout requirements.

[0043] According to one embodiment of this application, the front side of the housing 100 is provided with an opening for storing and retrieving items, and the terminal assembly 500 is installed on the side of the connection portion 220 away from the opening.

[0044] Understandably, the front of the cabinet 100 has an opening for storing and retrieving items (i.e., the door opening of the refrigerator / freezer for users to store or retrieve items). The terminal assembly 500 is located on the side away from the storage and retrieval opening to prevent users from accidentally touching or pulling the bus harness when frequently opening and closing the door or storing items, thus reducing the risk of human-caused damage. Furthermore, the front side of the refrigerator / freezer (near the door) is prone to temperature differences due to frequent opening and closing, leading to condensation buildup. Placing the terminal assembly 500 at the rear reduces this moisture contact, further preventing corrosion.

[0045] In one embodiment, the terminal assembly 500 is located on the rear sidewall of the connection portion 220, with a distance of ≥5mm from the back plate of the housing 100 (not shown in the figure), thereby ensuring heat dissipation.

[0046] According to one embodiment of this application, please refer to Figures 3 to 7 The air supply assembly 300 includes a volute 310, which is mounted on the air duct assembly 200. The volute 310 is at least partially located in the air supply duct 201. The air duct assembly 200 includes a rear baffle 270, a first air duct plate 250, and a second air duct plate 260. The first air duct plate 250 and the second air duct plate 260 are respectively connected to opposite sides of the volute 310. The rear baffle 270 is connected to the first air duct plate 250 and the second air duct plate 260. An independent wiring cavity 202 is formed between the first air duct plate 250, the rear baffle 270, and the volute 310. The terminal assembly 500 is at least partially located in the wiring cavity 202. The wire harness connecting the air supply assembly 300 passes through the wiring cavity 202 and connects to the terminal assembly 500.

[0047] The volute 310 is the mounting housing of the air supply assembly 300, and has a spiral structure to guide the efficient flow of air. The first air duct plate 250 and the second air duct plate 260 are respectively connected to opposite sides of the volute 310 (i.e., arranged on the left and right sides), and together with the volute 310, they enclose the air supply channel 201.

[0048] The wiring cavity 202 is formed by the additional enclosure of the first air duct plate 250, the rear baffle plate 270, and the volute 310, and the wiring cavity 202 is physically isolated from the air supply channel 201. The separation of the air supply channel 201 from the wiring cavity 202 can prevent defrosting moisture from entering the terminal area through the air duct.

[0049] According to one embodiment of this application, the volute 310 is provided with a front shield 311 and a side shield 312. The side shield 312 is opposite to the first air duct plate 250. The front shield 311 is connected to the side shield 312 and the first air duct plate 250. The front shield 311 is opposite to the rear shield plate 270. The side shield 312 is connected to the rear shield plate 270. The front shield 311 and the side shield 312 are located between the air supply channel 201 and the wiring cavity 202.

[0050] Understandably, the front shield 311 connects to the side shield 312 and the first air duct plate 250, and is opposite to the rear shield 270, forming a continuous sealed boundary. The front shield 311 and the side shield 312 are located between the air supply duct 201 and the wiring cavity 202, which can prevent moisture and dust in the airflow from entering the wiring cavity, thus avoiding electrical components from getting damp or short-circuiting.

[0051] According to one embodiment of this application, at least one of the rear shield 270 and the front shield 311 is provided with a recessed structure, which forms part of the cavity wall of the wiring cavity 202. The recessed structure can increase the effective volume of the wiring cavity 202 without increasing the external dimensions.

[0052] Specifically, the embodiments include providing a recessed structure only on the side wall of the volute 310 facing the rear baffle 270; providing a recessed structure only on the surface of the rear baffle 270 facing the volute 310; and providing recessed structures on both the volute 310 and the rear baffle 270.

[0053] According to one embodiment of this application, please refer to Figure 8 The angle between the mounting axis of the terminal assembly 500 and the normal to the mounting surface of the connecting part 220 is 60° to 90°.

[0054] Understandably, when the bus harness is connected from the rear or side of the device, a tilt angle of 60° to 90° allows the cable to bend naturally, reducing bending stress and preventing fatigue breakage of the cable due to long-term use. At the same time, it makes it easier for users to directly plug and unplug the cable from the back of the refrigeration equipment, reducing the difficulty of operation.

[0055] In addition, the side space of the protruding part of the connecting part 220 can be effectively utilized to reduce the occupation of other positions of the air duct assembly 200.

[0056] According to one embodiment of this application, the refrigeration equipment includes a second liner 600, which is installed in the cavity 101 and above the first liner 400. The second liner 600 is provided with a third refrigeration chamber 610 and a fourth refrigeration chamber 620. The third refrigeration chamber 610 is located on the first side of the air duct assembly 200, and the fourth refrigeration chamber 620 is located on the second side of the air duct assembly 200. The air duct assembly 200 includes a first air duct assembly 210, a connecting part 220, and a second air duct assembly 230 arranged sequentially along the height direction. The first air duct assembly 210 connects to the connecting part 220 and the second air duct assembly 230. The first air duct assembly 210 is connected to the first box liner 400, and the second air duct assembly 230 is connected to the second box liner 600. The connecting part 220 is located between the first box liner 400 and the second box liner 600.

[0057] Understandably, the second refrigeration chamber 600 is installed above the first refrigeration chamber 400, together forming an upper and lower partitioned refrigeration space. The third refrigeration chamber 610 is located on the first side of the air duct assembly 200, and the fourth refrigeration chamber 620 (such as an ice-making chamber) is located on the second side of the air duct assembly 200. The third refrigeration chamber 610 and the fourth refrigeration chamber 620 form a vertical correspondence with the first refrigeration chamber 410 and the second refrigeration chamber 420 on the lower level. The upper and lower layout maximizes the use of the equipment height space.

[0058] The air duct assembly 200 includes a first air duct assembly 210, a connecting portion 220, and a second air duct assembly 230 arranged sequentially along the height direction. The first air duct assembly 210 and the second air duct assembly 230 are respectively connected to the first liner 400 and the second liner 600, realizing air circulation and temperature regulation in the two cooling spaces. The connecting portion 220 is located between the first liner 400 and the second liner 600, serving both as a connection and transition, and providing space for the installation of the terminal assembly 500.

[0059] According to one embodiment of this application, please refer to Figures 8 to 10 The terminal assembly 500 includes an insulating terminal box 510 and a plurality of conductive terminals (not shown in the figure). The insulating terminal box 510 is mounted on the outside of the first connecting part 221, and the conductive terminals are mounted on the insulating terminal box 510.

[0060] Understandably, the insulating terminal box 510 is made of insulating material, possessing excellent electrical insulation properties and mechanical strength. It is installed on the outside of the first connection portion 221, providing protection and support for the internal conductive terminals. The conductive terminals are installed inside the insulating terminal box 510. The number and layout of the conductive terminals are customized according to the electrical requirements of the refrigeration equipment to ensure the reliability and stability of the electrical connection.

[0061] According to one embodiment of this application, the insulating terminal box 510 includes a box body 511, a first mounting part 512 and a second mounting part 513. The first mounting part 512 is connected to the top of the first connecting part 221, and the second mounting part 513 is connected to the side wall of the first connecting part 221.

[0062] The main body 511 is the main part of the insulated terminal box 510. Made of insulating material, the main body 511 possesses excellent electrical insulation properties and mechanical strength. The interior of the main body 511 provides space and structure for installing conductive terminals, offering a stable environment for electrical connections.

[0063] The first mounting portion 512 is located on the first side of the box body 511. The first mounting portion 512 is tightly connected to the top of the first connecting portion 221, ensuring a stable connection between the insulating terminal box 510 and the air duct assembly 200. At the same time, the first mounting portion 512 also serves to support and fix the box body 511.

[0064] The second mounting portion 513 is located on the second side of the box body 511, with the first and second sides facing each other. The second mounting portion 513 is tightly connected to the side wall of the first connecting portion 221, further enhancing the stability of the insulating terminal box 510. Through the combined action of the first mounting portion 512 and the second mounting portion 513, the insulating terminal box 510 can be firmly installed on the outside of the first connecting portion 221, ensuring the safety and reliability of the electrical connection.

[0065] According to one embodiment of this application, a sealing gasket 700 is provided between the terminal assembly 500 and the connecting portion 220, and the sealing gasket 700 is disposed around the mounting surface of the terminal assembly 500. The sealing gasket 700 improves the sealing performance between the terminal assembly 500 and the connecting portion 220.

[0066] According to one embodiment of this application, please refer to Figure 10 The connecting part 220 includes an air duct part 222, a first connecting part 221 and a second connecting part 223 arranged along the height direction. The first connecting part 221 is connected to the first air duct assembly 210 and the second connecting part 223 is connected to the second air duct assembly 230. Along the thickness direction of the housing 100, the lateral dimensions of the first connecting part 221 and the second connecting part 223 are both larger than those of the air duct part 222. The terminal assembly 500 is installed on the outside of the first connecting part 221.

[0067] Understandably, the air duct section 222 is arranged along the height direction to connect the first air duct assembly 210 and the second air duct assembly 230, ensuring smooth airflow between the two refrigeration chambers. The first connecting section 221 is located below the air duct section 222 and is tightly connected to the first air duct assembly 210, serving as a transition and connection. Its lateral dimension is larger than that of the air duct section 222, providing more stable support for the air duct section 222 and enhancing the connection strength with the first air duct assembly 210. The second connecting section 223 is located above the air duct section 222 and is tightly connected to the second air duct assembly 230, also serving as a transition and connection. Its lateral dimension is also larger than that of the air duct section 222, further enhancing the overall stability and connectivity of the connecting section 220.

[0068] In this embodiment, the terminal assembly 500 is installed on the outside of the first connecting part 221. Since the lateral dimension of the first connecting part 221 is larger than that of the air duct part 222, the terminal assembly 500 is not restricted by the air duct part 222 during installation, thus allowing for more flexible layout and connection.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
