Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a drying heat recovery structure for a commercial dishwasher. Background Technology

[0002] Dishwashers are devices that automatically clean tableware such as bowls, plates, cutlery, and knives. There are many types of dishwashers, which are widely used in restaurants, hotels, canteens, and homes to reduce labor intensity, improve work efficiency, and enhance cleanliness and hygiene.

[0003] According to a dishwasher with a heat recovery device (publication number: CN219680539U3) disclosed in the above application, the steam in the dryer is forcibly discharged by the cooperation of the fan and the outer shell. By setting up a condenser, the impact of steam on the operating environment is reduced. Both the inlet and outlet of the condenser are connected to external water pipes, which can heat the cold water entering from the inlet and deliver it to the dishwasher, thereby reducing the energy consumed by the dishwasher in heating water.

[0004] However, in actual use, when the fan forces the steam in the dryer through the condenser to discharge, the steam often carries impurities such as oil stains produced by the dishwasher after cleaning. Over time, this will cause pollution to the surface of the condenser. In view of this, we propose a heat recovery structure for drying in commercial dishwashers. Utility Model Content

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a heat recovery structure for drying in a commercial dishwasher, including a dryer body 1, a support leg 11 fixedly connected to the bottom surface of the dryer body 1, a recovery box 12 fixedly connected to the upper surface of the dryer body 1, and a recovery mechanism 2 provided inside the recovery box 12. The recovery mechanism 2 includes: a collection chamber 21, a transport pipe 22, a condenser 23, a condenser pipe 24, a telescopic cylinder 25, a cleaning cylinder 26, a motor 27, a rotating gear 28, a connecting gear 29, a cleaning brush 210, a drain trough 211, and a drain pipe 212.

[0024] In one embodiment of this utility model, the bottom surface of the collection chamber 21 is fixedly connected to the exhaust gas output end of the dryer body 1. One end of the transport pipe 22 is fixedly connected to the top of the collection chamber 21, and the other end of the transport pipe 22 is fixedly connected to a condenser 23. A condenser pipe 24 is fixedly connected to the inner end of the condenser 23. A telescopic cylinder 25 is fixedly connected to the end of the recovery box 12 away from the transport pipe 22. A cleaning cylinder 26 is fixedly connected to the movable end of the telescopic cylinder 25. The bottom surface of the motor 27 is fixedly connected to the inner wall of the cleaning cylinder 26. The output end of the motor 27 is fixedly connected to the inner wall of a rotating gear 28, and the other end of the rotating gear 28 meshes with a connecting... A connecting gear 29 is rotatably connected to both ends of the interior of the cleaning cylinder 26. A cleaning brush 210 is fixedly connected to the inner wall of the connecting gear 29. A drain trough 211 is located on the outer surface of the condenser 23, and a drain pipe 212 is fixedly connected to the inner wall of the drain trough 211. The end of the cleaning brush 210 away from the connecting gear 29 abuts against the outer wall of the condenser pipe 24. A silicone gasket is provided on the outer wall of the cleaning cylinder 26. One end of a fixing frame is fixedly connected to the outer surface of the telescopic cylinder 25, and the other end of the fixing frame is fixedly connected to both ends of the interior of the recycling bin 12. The size of the connecting gear 29 matches the internal size of the cleaning cylinder 26, and the connecting gear 29... A circular groove is provided at the end of the 9. Limiting blocks matching the size of the groove are fixedly connected to both ends of the cleaning cylinder 26. The high-temperature exhaust gas produced by the dryer body 1 can be efficiently collected through the collection chamber 21. Furthermore, the transport pipe 22 can transport the exhaust gas into the condenser 23. The high-temperature exhaust gas undergoes efficient heat exchange with the condensate in the condenser pipe 24. Additionally, the oil contained in the exhaust gas adheres to the outer wall of the condenser pipe 24 and the inner wall of the condenser 23. At this time, the telescopic cylinder 25 pushes the cleaning cylinder 26 to move inside the cylindrical condenser 23. When the cleaning cylinder 26 moves, a... The motor 27, located inside the cleaning cylinder 26, rotates synchronously. Furthermore, the motor 27 drives the rotating gear 28 to rotate, which in turn drives the connecting gear 29 to rotate, causing the connecting gear 29 to rotate on the inner wall of the cleaning cylinder 26. When the connecting gear 29 rotates, the cleaning brush 210, located on the inner wall of the connecting gear 29, can brush the outer surface of the condenser tube 24. At the same time, the silicone pad can tightly adhere to the inner wall of the condenser 23, pushing the dirt adhering to the inner wall of the condenser 23 into the drain pipe 212 through the drain trough 211, and then discharging it out of the device through the drain pipe 212.

[0025] In addition, a cooling mechanism 3 is installed inside the recycling bin 12. The cooling mechanism 3 includes a connecting pipe 31. One end of the connecting pipe 31 is fixedly connected to the end of the condenser pipe 24, and the other end of the connecting pipe 31 is fixedly connected to the input end of the pump 32. The output end of the pump 32 is fixedly connected to the water tank 33. The side wall of the water tank 33 is fixedly connected to the heat dissipation fins 34. The output end of the water tank 33 is fixedly connected to the end of the condenser pipe 24 near the telescopic cylinder 25 through the connecting pipe 31. There are two sets of cooling mechanisms 3, and the cooling mechanisms 3 are distributed in a mirror symmetrical manner on both sides of the outer surface of the condenser 23. The pump 32 can drive the coolant to circulate continuously between the water tank 33 and the condenser pipe 24 to achieve the highest heat exchange efficiency for the exhaust gas. The heat dissipation fins 34 can increase the heat dissipation area between the condensate and the external environment to achieve a better heat dissipation effect. Furthermore, there are two sets of cooling mechanisms 3. The two independent cooling mechanisms 3 can increase the cooling effect while improving the safety redundancy of the equipment.

[0026] In this embodiment of the present invention, one end of a ventilation pipe 4 is fixedly connected to the outer surface of the condenser 23, and the other end of the ventilation pipe 4 is fixedly connected to a fan 41. The output end of the fan 41 is fixedly connected to an exhaust pipe 42. The transport pipe 22 and the ventilation pipe 4 are connected to the upper part of the outer surface of the condenser 23. The drain trough 211 is opened on the bottom side of the condenser 23. The condenser 23 is cylindrical in shape. The fan 41 can extract the cooled exhaust gas through the ventilation pipe 4. Further exhaust gas is discharged through the exhaust pipe 42. The transport pipe 22 and the ventilation pipe 4 are connected to the upper part of the outer surface of the condenser 23. The drain trough 211 is opened on the bottom side of the condenser 23 to prevent the distilled water generated between the exhaust gas and the condenser pipe 24 from flowing out from the transport pipe 22 and the ventilation pipe 4. The drain trough 211 is set on the bottom surface to discharge distilled water in a timely manner.

[0027] In this invention, during use, the exhaust gas generated by the dryer body 1 first enters the collection chamber 21, and then is transported to the cylindrical condenser 23 through the transport pipe 22. The heat in the exhaust gas is exchanged and recovered by the internal condenser pipe 24, while the cooling mechanism 3 drives the coolant in the water tank 33 to circulate in the connecting pipe 31 and the condenser pipe 24 through the pump 32, and dissipates heat through the heat dissipation fins 34, thereby cooling the exhaust gas. The cooled exhaust gas is then discharged through the ventilation pipe 4 by the fan 41 and the exhaust pipe 42. At the same time, the telescopic cylinder 25 of the recovery mechanism 2 can push the cleaning cylinder 26 to move, so that it wraps around the condenser pipe 24. Then, the motor 27 drives the rotating gear 28 and the connecting gear 29 to rotate, driving the cleaning brush 210 to clean the outer wall of the condenser pipe 24. The removed dirt is finally discharged through the drain trough 211 and the drain pipe 212 at the bottom.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
