Description

Technical Field

[0001] The utility model relates to the technical field of commercial inspection of air source heat pump water heaters, in particular to a waterless commercial inspection device for an integral air source heat pump water heater. Background Art

[0002] With the growing awareness of energy conservation and emission reduction and technological advancements, air-source heat pump water heaters are gaining widespread adoption worldwide as an efficient, green water heating solution. In China, in particular, with the government's strong push for new energy applications, market demand for these products continues to grow, leading to a continuous expansion in production. However, this presents a new challenge: ensuring that these mass-produced water heaters meet high standards for performance and safety. This is especially true given the increasing urgency of precise testing within the complex internal environment of these water heaters.

[0003] Traditional water injection testing requires a large production line layout space for the water heater to be inspected to accommodate hardware equipment such as water tanks, cooling systems, connecting pipes, drainage systems, and electronic control valves. This not only increases the floor space of the production workshop, but also limits the flexibility of the production line layout, making it difficult to improve overall production efficiency. Secondly, the time it takes to heat water is significantly extended because the specific heat capacity of water is much higher than that of air, which increases the inspection cycle and greatly affects the inspection efficiency. In addition, during the inspection process of water heaters heated by water, a large water temperature increase range needs to be achieved to fully evaluate its performance. However, within the limited inspection time, we can only capture the operating parameters of the water temperature within a relatively narrow range of variation. This limitation cannot fully reflect the true operating conditions of the equipment. Utility Model Content

The commercial inspection barcode identifier 5 is electrically connected to the control unit to automatically identify and enter the basic information of the water heater to be inspected 8 into the control unit.

[0027] As a preferred implementation scheme of this embodiment, the ports to be tested are respectively an air inlet 9, an air outlet 10 and a water outlet 11. The air inlet 9 and the air outlet 10 are respectively arranged on the top of the water heater to be tested 8, and the water outlet 11 is arranged on the side of the water heater to be tested 8 and faces the side of the stand; each of the ports to be tested matches one of the temperature measuring components 4 and the telescopic rod 3.

[0032] The working process of this embodiment:

[0033] During operation, the water heater 8 to be inspected is first fixedly mounted on the mobile workbench 2, connected to the power interface 7, and the air inlet 9, air outlet 10, and water outlet 11 on the workbench are ensured to be in positions that are easily accessible for inspection.
