Description

Technical Field

[0001] This utility model relates to the field of drinking water heating technology, specifically a campus drinking water heating device. Background Technology

[0002] In campus public drinking water settings, to meet the immediate needs of teachers and students for different water temperatures, existing drinking water heating devices typically integrate cold water supply and hot water heating functions. They output room temperature water and heated hot water through independent pipelines to accommodate diverse needs such as direct drinking, tea brewing, and beverage preparation. These devices generally use electric heating elements to heat the water. Their core design logic lies in ensuring a stable hot water output temperature through temperature control components and achieving room temperature water supply through physically isolated cold water channels. They have become standard equipment in campus corridors, classrooms, and other similar locations. In actual use, the large amount of water vapor generated during the hot water heating process is usually directly discharged into the environment through the exhaust structure. The latent heat of vaporization contained in this vapor is not effectively recovered. This waste heat loss leads to a decrease in overall energy utilization efficiency, and this energy waste is even more prominent during peak periods of centralized water supply on campus. At the same time, the unorganized emission of water vapor not only causes energy loss, but may also form condensation on the equipment surface, increasing the risk of pipeline corrosion and reducing the service life of the equipment.

[0003] In order to recover and utilize the water vapor generated by hot water heating, fully extract its latent heat of vaporization, and improve energy utilization efficiency, we propose a campus drinking water heating device. Utility Model Content

The condenser tube 20 exchanges heat with the cold water in the preheating tank 14 to achieve the effect of preheating. The condenser tube 20 is set as a spiral tube, which increases the contact area and contact time, and improves the heat energy recovery and utilization rate. After the water vapor releases heat, it condenses into liquid and flows back to the water storage tank 7 through the return pipe 16.

The end of the third conveying pipe 19 away from the third liquid pump 37 is fixedly connected to a heating box 11.

[0026] Start the first liquid pump 36 to draw water from the water storage tank 7 through the first water pumping pipe 34, and then transport it to the preheating tank 14 for preheating through the first delivery pipe 9. Then start the third liquid pump 37 to transport water to the heating box 11 with the cooperation of the third water pumping pipe 38 and the third delivery pipe 19.

A moving mechanism that drives the mounting plate 28 to move is installed on the sliding frame 23. A collection mechanism that collects debris after cleaning is installed on the housing 1.

[0028] The lifting mechanism drives the sliding frame 23 to rise, which in turn drives the mounting plate 28 to rise, allowing the cleaning brush to clean the surface of the placement plate 2.

The cleaned impurities are collected by the collection mechanism.

[0029] The lifting mechanism includes an electric push rod 21, which is fixedly installed on the top of the water storage tank 7.

Controlling the electric push rod 21 drives the connecting frame 22 to rise, which in turn drives the sliding frame 23 to rise.

[0030] The moving mechanism includes a mounting cover 27, which is fixedly connected to the rear side of the sliding frame 23. A screw 29 is rotatably mounted on the inner wall of the mounting cover 27. A moving block 30 is slidably connected to the inner wall of the mounting cover 27. The screw 29 is threaded through the moving block 30. A connecting block 33 is fixedly connected to the top of the moving block 30. A second sliding opening that matches the connecting block 33 is provided on the mounting cover 27. The connecting block 33 is slidably connected to the second sliding opening.

[0031] The drive mechanism includes a motor 26, which is fixedly installed on the rear side of the mounting cover 27.

The drive bevel gear 31 meshes with the rotating bevel gear 32.

[0032] The start motor 26 drives the drive bevel gear 31 to rotate, which in turn drives the screw 29 to rotate, thus moving the moving block 30 and causing the connecting block 33 and the mounting plate 28 to move.

[0033] The recycling mechanism includes a recycling cover 12, which is fixedly installed on the inner wall of the housing 1. A collection box 5 is slidably installed on the inner wall of the recycling cover 12, and the collection box 5 slides out of the housing 1.

A lifting plate 25 is fixedly connected to the top of the sliding frame 23. The side of the lifting plate 25 closest to the housing 1 abuts against the housing 1. This prevents water or other impurities from entering the housing 1.

[0035] Working principle: During use, drinking water is injected into the water storage tank 7 through the inlet pipe 6. The second liquid pump 17 is started, and water is drawn from the water storage tank 7 through the second pumping pipe 35 and delivered to the ambient temperature water pipe 4 through the second delivery pipe 10, allowing users to directly collect ambient temperature water from the ambient temperature water pipe 4. The first liquid pump 36 is started, and water is drawn from the water storage tank 7 through the first pumping pipe 34 and delivered to the preheating tank 14 through the first delivery pipe 9 for preheating. Then, the third liquid pump 37 is started, and with the cooperation of the third pumping pipe 38 and the third delivery pipe 19, water is delivered to the heating box 11, which is equipped with several sets of electric heating rods. By heating the water, users can access hot water at the hot water pipe 3, thus meeting their different water needs. During this process, the water vapor generated when the hot water in the heating box 11 is heated enters the condenser pipe 20 through the steam pipe 13. The condenser pipe 20 exchanges heat with the cold water in the preheating tank 14 to achieve the effect of preheating. The condenser pipe 20 is set as a spiral pipe, which increases the contact area and contact time, and improves the heat recovery and utilization rate. Thus, the latent heat of vaporization in the water vapor can be fully recovered and utilized, improving energy utilization efficiency. After releasing heat, the water vapor condenses into liquid and flows back to the water storage tank 7 through the return pipe 16. In addition, during the process of users collecting drinking water, water that is accidentally spilled or overflows will fall onto the placement plate 2, enter the water tank 8 through the through holes on the placement plate 2, and finally be discharged through the drain pipe 18. Solid debris such as tea leaves and petals that fall onto the placement plate 2 along with the water can be cleaned by the cleaning component: the electric push rod 21 is controlled to drive the connecting frame 22 to rise, drive the sliding frame 23 to rise, and drive the mounting plate 28 to rise, so that the cleaning brush can clean the surface of the placement plate 2. Then the motor 26 is started to drive the drive bevel gear 31 to rotate. By rotating the bevel gear 32, the screw 29 is driven to rotate, and the moving block 30 moves, driving the connecting block 33 and the mounting plate 28 to move. The moving cleaning brush cleans the impurities on the surface of the placement plate 2. The cleaned impurities fall into the collection box 5 on the recycling cover 12. After a period of use, the collection box 5 can be removed for cleaning to ensure the cleanliness and hygiene of the equipment.
