DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0025] See also Figure 1-5 As shown, an exhaust device for a refrigerator includes an exhaust assembly 10 installed near the refrigerator, a retractable air supply duct 20 is arranged on the upper side of the exhaust assembly 10, and the upper end of the air supply duct 20 extends outward to the outside of the workshop, and a trigger assembly 40 is arranged on the exhaust assembly 10. When the temperature is high, the trigger assembly 40 triggers the exhaust assembly 10 to start, and the exhaust assembly 10 can discharge the heat near the refrigerator to the outside of the workshop through the air supply duct 20, thereby reducing the temperature in the workshop and creating a comfortable working environment for the operators.

[0026] The air supply duct 20 includes a first duct 21 and a second duct 22, wherein the second duct 22 is connected to the wall of the workshop so that the wall of the workshop can provide stable support for the second duct 22. The first duct 21 and the second duct 22 are plug-in connected so that the first duct 21 can move along the surface of the second duct 22. Specifically, the second duct 22 is plugged into the inside of the first duct 21. A first fixing column 31 is provided on the surface of the first duct 21, and a second fixing column 33 is provided on the surface of the second duct 22. A spring 32 is connected between the first fixing column 31 and the second fixing column 33. One end of the spring 32 is connected to the first fixing column 31, and the other end of the spring 32 is connected to the second fixing column 33.

[0027] In the natural state, the spring 32 pulls the first fixing column 31, so that the first pipe 21 and the exhaust assembly 10 are in a separated state, so that the heat generated by the refrigerator can be dissipated into the workshop, increasing the temperature in the workshop, which is suitable for the need of heating the workshop in winter; then the first pipe 21 is moved downward, so that the first pipe 21 contacts the exhaust assembly 10, which is convenient for discharging the heat generated by the refrigerator through the exhaust assembly 10, which is suitable for the environment with higher workshop temperature. It should be noted here that the exhaust assembly 10 and the first pipe 21 are connected by a buckle, and the buckle is used to fix the first pipe 21 and the exhaust assembly 10, and the use process is relatively convenient.

[0028] The exhaust assembly 10 includes a support frame 11 and a fan 12. The fan 12 is arranged inside the support frame 11. The support frame 11 is mounted on the upper side of the refrigerator so that the air intake end of the fan 12 faces the heat dissipation end of the refrigerator, so that the heat emitted by the refrigerator is discharged to the outside of the workshop through the fan 12 and the air supply duct 20. The trigger assembly 40 is arranged inside the support frame 11, so that the trigger assembly 40 can monitor the temperature near the heat dissipation port of the refrigerator. When the temperature near the heat dissipation port is high, the trigger assembly 40 triggers the fan 12 to start.

[0029] The trigger assembly 40 includes a sphere 41, and the sphere 41 has a receiving cavity inside. The receiving cavity contains an expansion medium, which is one of alcohol, kerosene or air. The expansion medium expands in volume when heated. A conduit 42 is provided at the upper end of the sphere 41, and the lower end of the conduit 42 is connected to the receiving cavity inside the sphere 41. A piston rod 43 is inserted into the conduit 42, so that the piston rod 43 can move along the axial direction inside the conduit 42. Specifically, a slide groove 45 is provided inside the conduit 42 in the vertical direction, and a slider is provided at the lower end of the piston rod 43. The slider can move along the slide groove 45. An air outlet 44 is provided at the top of the slide groove 45, so that the slide groove 45 is connected to the outside world, so that the gas inside the slide groove 45 can be discharged in time, the air pressure stability in the slide groove can be ensured, and the piston rod 43 can move up and down. The trigger assembly 40 also includes a contact switch (not shown) mounted on the support frame 11. The contact switch is electrically connected to the fan 12. The contact switch is located on the upper side of the piston rod 43. When the piston rod 43 moves upward, the contact switch is in a connected state, and the fan 12 is powered on and started to discharge the hot air.

[0030] When the temperature of the heat dissipation outlet of the refrigerator is high, the expansion medium expands due to the heat, and lifts the piston rod 43. The piston rod 43 acts on the contact switch, and the fan 12 is energized to discharge the hot air through the air supply duct 20 (at this time, the first duct 21 is in contact with the exhaust assembly 10); when the temperature of the heat dissipation outlet of the refrigerator is low, the expansion medium contracts, the piston rod 43 moves downward and retracts, the piston rod 43 separates from the contact switch, the fan 12 is powered off, and the device does not discharge the hot air.

[0031] In this specific embodiment, when used in summer, the first pipe 21 is moved downward so that the first pipe 21 contacts the exhaust assembly 10. When the temperature of the heat dissipation port of the refrigerator is high, the expansion medium expands due to the heat, and the piston rod 43 is lifted. The piston rod 43 acts on the contact switch, and the fan 12 is energized to discharge the hot air through the air supply duct 20. During winter use, the first pipe 21 is moved upward so that the first pipe 21 is separated from the exhaust assembly 10, and the heat generated by the refrigerator is discharged into the workshop to meet the heating needs of the workshop.
