Description

Technical Field

[0001] This utility model relates to the field of air cooling, and in particular to an air-cooled refrigerator that avoids corrosion of the connection terminals. Background Technology

[0002] In the refrigerator industry, refrigerators with a capacity of 150 liters or less are generally referred to as small refrigerators. Some small refrigerators now feature a frost-free cooling system, which controls the flow of cold air by arranging an integrated air duct within the refrigerator's interior. To detect the internal temperature, a temperature sensor is typically placed at the air return vent of the air duct. To connect the temperature sensor, a female connector is installed on the back of the refrigerator's interior, which connects to the refrigerator's control circuit board. A male connector is then connected to the temperature sensor via a wire. The mating of the male and female connectors facilitates installation. However, a problem exists: in current methods, a channel is typically created within the air duct to route the wires. This results in the male and female connectors being directly connected to the refrigerator's air duct through this channel. Since the air in the air duct is low-temperature and high-humidity, it easily corrodes the male and female connectors, leading to moisture absorption, corrosion, and damage over time. Meanwhile, the female terminal is installed by opening an installation port directly on the vertical back of the enclosure, which results in the female terminal being arranged horizontally. This requires the male terminal to also be connected horizontally, thus occupying too much horizontal space. As a result, it affects the air duct layout of the main body of the air duct, resulting in a larger size of the main body of the air duct. Utility Model Content

[0003] To solve the above problems, the purpose of this utility model is to provide an air-cooled refrigerator that facilitates the connection between male and female terminals and prevents the male and female terminals from being damaged by moisture.

[0004] The technical solution adopted by this utility model to solve the problem is: a wind-cooled refrigerator that avoids corrosion of connection terminals, comprising: The box body has a box liner inside, which forms a box cavity. The rear side of the box liner bulges outward to form a bulge so that the inner sidewall of the box cavity forms a sub-cavity. The top of the bulge slopes downward toward the rear side of the box liner, and the top of the bulge is provided with a mounting hole that communicates with the sub-cavity. The air duct body is fixedly installed in the box cavity. The back of the air duct body covers the sub-cavity. The air duct body is provided with an air duct. The box liner is provided with a mating hole for the air duct port. A temperature sensor is provided in the air duct. The back of the air duct body is provided with a connection channel that communicates with the air duct. A wire is connected to the temperature sensor, passing through the connection channel and extending into the sub-cavity. The end of the wire is provided with a male terminal. A sealing element is arranged in the connecting channel and pressed against the outer periphery of the wire. The main body of the air duct isolates the sub-cavity into a sealed space through the sealing element and its cooperation with the inner wall of the box. The female terminal is fixed to the mounting hole and extends into the female cavity, where it is detachably connected to the male terminal.

[0005] As a further improvement to the above technical solution, the end of the connecting channel near the back of the air duct body is square.

[0006] As a further improvement to the above technical solution, a reinforcing plate is provided at the bottom of one end of the connecting channel near the back of the air duct body. The reinforcing plate includes an inclined section at the front end and a horizontal section at the rear end, and the inclined section is triangular in shape.

[0007] As a further improvement to the above technical solution, the inner sidewall of the box cavity is provided with an installation groove extending to the top of the box cavity, the sub-cavity is provided on the bottom surface of the installation groove, and the main body of the air duct is arranged on the installation groove.

[0008] As a further improvement to the above technical solution, the mounting groove is provided with at least two downwardly extending slots on the lower end face below the sub-cavity, the bottom of the air duct body is provided with a pin that can be inserted into the slot, the air duct body is provided with bolt holes, and the outer periphery of the box liner is provided with bolts that pass through the box liner and are screwed to the bolt holes.

[0009] As a further improvement to the above technical solution, the bolt holes are arranged at the top of the air duct body, and the bolts are set at the top of the box liner and screwed into the bolt holes.

[0010] As a further improvement to the above technical solution, a sealing gasket is arranged between the air duct body and the inner wall of the box cavity, surrounding the outside of the connecting channel.

[0011] As a further improvement to the above technical solution, the sealing gasket is a sponge.

[0012] As a further improvement to the above technical solution, the connection channel includes a first section disposed on the back of the air duct body, a second section connected to the rear side of the first section, and a third section connected to the rear side of the second section. The size of the first section is larger than that of the second section, and the sealing element is sealed into the second section.

[0013] As a further improvement to the above technical solution, the air duct includes an outlet air duct and a return air duct. One end of the outlet air duct is located at the top of the air duct body and the other end is located at the front end of the air duct body. The return air duct includes a return air groove located at the rear side of the top of the air duct body and a connecting channel connected to the return air groove and extending to both sides of the top of the air duct body.

[0014] The beneficial effects of this utility model are as follows: By setting an outwardly bulging bulge on the rear side of the box liner and forming a sub-cavity on the inner wall of the box cavity, the top of the bulge is inclined and has mounting holes for female terminals, so that the female terminals are inserted into the sub-cavity at an angle. A connecting channel connected to the air duct body is provided on the air duct body to arrange the wires. The end of the wire is provided with a male terminal located in the sub-cavity to connect with the female terminal. After connection, the male and female terminals are in an inclined state, so the size occupied in the lateral space is small. At the same time, by setting a sealing element to close the connecting channel and press it on the outer periphery of the wires, the air duct body isolates the sub-cavity into a sealed space through the sealing element and the cooperation with the inner wall of the box liner. Therefore, the cold air in the air duct will not be conducted into the sub-cavity, thus making it less likely to corrode the male and female terminals, and improving safety.

[0021] Reference Figures 1 to 7 A type of air-cooled refrigerator that avoids corrosion of connection terminals, comprising: The box body has a box liner 10 inside, and a box cavity 11 is formed inside the box liner 10. The rear side of the box liner 10 bulges outward to form a bulge 12 so that the inner side wall of the box cavity 11 forms a sub-cavity 121. The top of the bulge 12 slopes downward toward the rear side of the box liner 10, and the top of the bulge 12 is provided with a mounting hole 122 that communicates with the sub-cavity 121. The air duct body 20 is fixedly installed in the box cavity 11. The back of the air duct body 20 covers the sub-cavity 121. The air duct body 20 is provided with an air duct. The box liner 10 is provided with a mating hole for the air duct port. A temperature sensor is provided in the air duct. The back of the air duct body 20 is provided with a connecting channel 30 that communicates with the air duct. A wire 22 is connected to the temperature sensor, passing through the connecting channel 30 and extending into the sub-cavity 121. The end of the wire 22 is provided with a male terminal 23. A sealing element 40 is arranged in the connecting channel 30 and pressed against the outer periphery of the wire 22. The air duct body 20 isolates the sub-cavity 121 into a sealed space through the sealing element 40 and its cooperation with the inner wall of the box liner 10. The female terminal 60 is fixed to the mounting hole 122 and extends into the female cavity 121, where it is detachably connected to the male terminal 23.

[0022] By setting an outwardly bulging 12 on the rear side of the box liner 10 and forming a sub-cavity 121 on the inner wall of the box cavity 11, the top of the bulge 12 is inclined and a mounting hole 122 is arranged to set the female plug terminal 60, so that the female plug terminal 60 is inserted into the sub-cavity 121 at an angle. A connecting channel 30 connected to the air duct body 20 is provided on the air duct body 20 to arrange the wire 22. The end of the wire 22 is provided with a male plug terminal 23 located in the sub-cavity 121 to connect with the female plug terminal 60. After the connection, the male plug terminal 23 and the female plug terminal 60 are in an inclined state, so the size occupied in the lateral space is small. At the same time, a sealing element 40 is set to seal the connecting channel 30 and press it on the outer periphery of the wire 22, so that the air duct body 20 isolates the sub-cavity 121 into a sealed space through the sealing element 40 and the cooperation with the inner wall of the box liner 10. Therefore, the cold air in the air duct will not be conducted into the sub-cavity 121, and thus it is not easy to corrode the male plug terminal 23 and the female plug terminal 60, resulting in better safety.

[0023] In this embodiment, the preferred connection channel 30 includes a first section 31 disposed on the back of the air duct body 20, a second section 32 connected to the rear side of the first section 31, and a third section 33 connected to the rear side of the second section 32. The first section 31 is larger than the second section 32. The sealing member 40 seals the second section 32. Thus, the first section 31 is used to cooperate with the sub-cavity 121 to form a larger sealing space, thereby better accommodating the male terminal 23 and the female terminal 60. The sealing member 40 is used to seal the second section 32, while the third section 33 is used to normally arrange the wires 22, giving the wires 22 more free space to adjust their orientation.

[0024] In this design, to facilitate the insertion of the sealing element 40 into the connecting channel 30 to form a seal, it is preferable that the end of the connecting channel 30 near the back of the air duct body 20 is square.

[0025] To further optimize the design and facilitate the insertion of the seal 40, a reinforcing plate 34 is preferably provided at the bottom of one end of the connecting channel 30 near the back of the air duct body 20. The reinforcing plate 34 includes an inclined section 341 at the front end and a horizontal section 342 at the rear end, with the inclined section 341 being triangular in shape. The reinforcing plate 34 serves two purposes: firstly, it strengthens the bottom of the connecting channel 30, preventing deformation; secondly, when the seal 40 is inserted into the connecting channel 30, the reinforcing plate 34 provides a guiding effect on the bottom of the seal 40, ensuring a tight fit of the seal 40 within the connecting channel 30.

[0026] Further optimization is preferred, with an installation groove 111 extending to the top of the box cavity 11 on the inner side wall, the sub-cavity 121 being disposed on the bottom surface of the installation groove 111, and the air duct body 20 being arranged on the installation groove 111, thereby facilitating the fixing of the air duct body 20.

[0027] In traditional methods, the duct body 20 is typically fixed using multiple bolts. To reduce the number of bolts used, it is preferable that the mounting groove 111, located below the sub-cavity 121, has at least two downwardly extending slots 1111 on its lower end surface. The bottom of the duct body 20 has a pin 201 that can be inserted into the slots 1111. The duct body 20 has bolt holes 24, and the outer periphery of the housing liner 10 has bolts that pass through the housing liner 10 and are screwed into the bolt holes 24. During installation, the duct body 20 is first tilted and placed into the housing 11, allowing the pin 201 at the bottom of the duct body 20 to insert into the slots 1111. Then, the duct body 20 is pushed until it is fully positioned in the mounting groove 111, and finally, a bolt is used for fixation. Preferably, the bolt holes 24 are located at the top of the duct body 20, and the bolts are located at the top of the housing liner 10 and screwed into the bolt holes 24.

[0028] In this design, to ensure the airtightness between the duct body 20 and the inner wall of the cavity 11, a sealing gasket 50 is preferably arranged around the outside of the connecting channel 30 between the duct body 20 and the inner wall of the cavity 11. The sealing gasket 50 is preferably a sponge, but can be made of soft rubber or other materials.

[0029] In this scheme, the arrangement of the air duct is varied. In this scheme, the preferred air duct includes an outlet air duct 211 and a return air duct. One end of the outlet air duct 211 is located at the top of the air duct body 20 and the other end is located at the front end of the air duct body 20. The return air duct includes a return air groove 212 located at the rear of the top of the air duct body 20 and a connecting channel 213 connected to the return air groove 212 and extending to both sides of the top of the air duct body 20.

[0030] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
