Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5This embodiment provides a technical solution: a heat exchange device for heat recovery of a catering kitchen air conditioner, comprising a housing 1, a heat conducting plate 12 provided at the front end of the interior of the housing 1, a control switch 13 provided on the right side of the housing 1, an input end of the control switch 13 electrically connected to an external power supply, a mounting ring 5 provided inside the housing 1, a water pipe 4 provided at the lower end of the mounting ring 5, the lower end of the water pipe 4 passing through the lower side wall of the housing 1, a threaded pipe 3 provided at the lower end of the water pipe 4 for connecting to an external water pipe, a water tank 6 rotatably connected to the interior of the mounting ring 5, and a protective shell 7 provided on the rear side of the housing 1. A motor 8 is installed inside the protective shell 7. The output shaft of the motor 8 is fixedly connected to the center of the rear side of the water tank 6. The input end of the motor 8 is electrically connected to the output end of the control switch 13. The front side of the water tank 6 is in contact with the rear side of the heat conducting plate 12. The interior of the water tank 6 is provided with evenly distributed partitions 10. The outer arc surface of the water tank 6 is provided with evenly distributed water inlet / outlet holes 11. The right end of the outer arc surface of the mounting ring 5 is provided with a water inlet pipe 9. The water inlet pipe 9 is installed in conjunction with the water inlet / outlet hole 11. The worker contacts the heat exchange device with the condenser heat dissipation component of the kitchen air conditioner. During the operation of the condenser The heat energy generated is transferred to the heat conducting plate 12. At this time, the worker pours the external water into the water tank 6 through the water inlet pipe 9 (before the heat exchange device performs heat exchange, one of the water inlet / outlet holes 11 on the arc surface of the water tank 6 fits with the left end of the water inlet pipe 9, so the external water can enter the water tank 6 through the water inlet pipe 9). At this time, the water inside the water tank 6 exchanges heat with the heat conducting plate 12 through the water tank 6. Then, in order to ensure the high efficiency of heat recovery and prevent the water inside the water tank 6 from not being able to fully contact the heat conducting plate 12, the worker controls the switch 13 to operate the motor 8. The output shaft of 8 drives the water tank 6 to rotate. The water inside the water tank 6 can contact a larger area of ​​the water tank 6 during the rotation. During the rotation of the water tank 6, the various water inlet / outlet holes 11 on its external surface are successively fitted with the left end of the water inlet pipe 9. At this time, the external water enters the space formed by every two partitions 10 inside the water tank 6 through the water inlet pipe 9. When the water first stored in the water tank 6 rotates to the bottom, it is discharged into the external water pipe through the water pipe 4 and the threaded pipe 3. It is collected by workers and recovers the heat energy generated by the condenser of the kitchen air conditioner through heat exchange. It also includes a connecting mechanism 2;

[0024] Connecting mechanism 2: It includes a rotating disk 21, a rotating seat 22 and an L-shaped splint 24. The rotating disk 21 is threadedly connected to the middle of the threaded tube 3. The outer arc surface of the rotating disk 21 is provided with evenly distributed rotating seats 22. The interior of the rotating seat 22 is rotatably connected to an L-shaped splint 24 for connecting to an external water pipe. The connecting mechanism 2 also includes a pin 23. The L-shaped splint 24 is rotatably connected to the interior of the rotating seat 22 through the pin 23. The connecting mechanism 2 also includes a connecting seat 25, a connecting disk 26 and a connecting rod 27. The connecting disk 26 is rotatably connected to the lower end of the threaded tube 3. The middle part of the connecting disk 26 is provided with a The outer arc surface of the connecting plate 26 is provided with evenly distributed connecting seats 25, and the interior of the connecting seats 25 is rotatably connected with connecting rods 27. The outer ends of the connecting rods 27 are rotatably connected to the interior of the longitudinally adjacent connecting seats 25. The worker first contacts the upper end of the external water pipe with the lower end of the connecting plate 26, and then rotates the rotating disk 21. The rotating disk 21 drives the rotating seat 22 to rotate, and then drives the L-shaped splint 24 to rotate through the pin shaft 23. At this time, the connecting rod 27 rotates synchronously. At this time, the connecting rod 27 drives the connecting plate 26 to rotate through the connecting seat 25. In this process, the thread on the threaded pipe 3 is screwed in cooperation. The turntable 21 moves downward while rotating. At this time, the rotating disk 21 and the connecting disk 26 do not rotate relatively, but the rotating disk 21 continues to approach the direction of the connecting disk 26. At this time, the rotating disk 21 drives the rotating seat 22 to move downward, and the rotating seat 22 drives the L-shaped clamping plate 24 to move downward through the pin 23. At this time, the upper end of the L-shaped clamping plate 24 drives the outer end of the connecting rod 27 to move downward. At this time, the connecting rod 27 is restricted by the connecting seat 25, and the horizontal position of the inner end of the connecting rod 27 remains unchanged and rotates (the central axis of the connecting rod 27 and the connecting disk 26 is not always perpendicular and the connecting rod 27 is not perpendicular to the connecting disk 26, the angle formed by the upper part of the central axis is less than 90 degrees), at this time, the outer end of the connecting rod 27 rotates with the adjacent connecting seat 25 as the center toward the direction away from the adjacent connecting seat 25, and the outer end of the connecting rod 27 begins to push the adjacent L-shaped clamping plate 24 outward (in the initial state, the middle part of the L-shaped clamping plate 24 is perpendicular to the ground, and the angle formed between the upper end of the L-shaped clamping plate 24 and its own middle part is greater than 90 degrees), and the L-shaped clamping plate 24 rotates with the adjacent pin shaft 23 as the center until the lower end of the L-shaped clamping plate 24 is clamped on the surface of the external water pipe, so as to facilitate the connection of the external water pipe to the heat exchanger.

[0025] The working principle of the heat exchange device for heat recovery of the catering kitchen air conditioner provided by the present invention is as follows: the worker brings the heat exchange device into contact with the condenser heat dissipation component of the kitchen air conditioner. During the operation of the condenser, the heat energy generated is transferred to the heat conducting plate 12. At this time, the worker pours external water into the water tank 6 through the water inlet pipe 9 (before the heat exchange device performs heat exchange, one of the water inlet / outlet holes 11 on the arc surface of the water tank 6 fits with the left end of the water inlet pipe 9, so the external water can enter the water tank 6 through the water inlet pipe 9). At this time, the water inside the water tank 6 undergoes heat exchange with the heat conducting plate 12 through the water tank 6. Then, in order to ensure the high efficiency of heat recovery, the water inside the water tank 6 is prevented from being unable to fill The water in the water tank 6 is in contact with the heat conducting plate 12, and the worker controls the switch 13 to operate the motor 8. The output shaft of the motor 8 drives the water tank 6 to rotate. The water inside the water tank 6 is in contact with more area of ​​the water tank 6. In the process of the rotation of the water tank 6, the various water inlet / outlet holes 11 on its external surface are fitted with the left end of the water inlet pipe 9 in turn. At this time, the external water enters the space formed by every two partitions 10 inside the water tank 6 through the water inlet pipe 9. When the water first stored in the water tank 6 rotates to the lower end, it is discharged into the external water pipe through the water pipe 4 and the threaded pipe 3 and collected by the worker. The worker first contacts the upper end of the external water pipe with the lower end of the connecting disk 26, and then rotates the rotating disk 21 to drive the rotating seat 22 to rotate. The L-shaped clamping plate 24 is rotated by the pin shaft 23, and the connecting rod 27 rotates synchronously. At this time, the connecting rod 27 drives the connecting plate 26 to rotate through the connecting seat 25. In this process, the rotating disk 21 rotates and moves downward at the same time under the cooperation of the threads on the threaded tube 3. At this time, the rotating disk 21 and the connecting plate 26 do not rotate relatively, but the rotating disk 21 continues to approach the direction of the connecting plate 26. At this time, the rotating disk 21 drives the rotating seat 22 to move downward, and the rotating seat 22 drives the L-shaped clamping plate 24 to move downward through the pin shaft 23. At this time, the upper end of the L-shaped clamping plate 24 drives the outer end of the connecting rod 27 to move downward. At this time, the connecting rod 27 is restricted by the connecting seat 25 and the inner end of the connecting rod 27 The horizontal position of the connecting rod 27 remains unchanged and the connecting rod 27 rotates (the central axis of the connecting plate 26 is not always perpendicular and the angle formed by the connecting rod 27 and the upper part of the central axis of the connecting plate 26 is less than 90 degrees). At this time, the outer end of the connecting rod 27 rotates with the adjacent connecting seat 25 as the center toward the direction away from the adjacent connecting seat 25, and the outer end of the connecting rod 27 begins to push the adjacent L-shaped clamping plate 24 outward (in the initial state, the middle part of the L-shaped clamping plate 24 is perpendicular to the ground, and the angle formed between the upper end of the L-shaped clamping plate 24 and its own middle part is greater than 90 degrees). The L-shaped clamping plate 24 rotates with the adjacent pin shaft 23 as the center until the lower end of the L-shaped clamping plate 24 is clamped on the surface of the external water pipe.

[0026] It is worth noting that the motor 8 disclosed in the above embodiment can be of model Y90L-4, and the control switch 13 is provided with a control button corresponding to the motor 8 and used to control its switch.
