Description

Technical Field

[0001] The utility model belongs to the technical field of water heaters, and in particular relates to an air energy water heater which is easy to assemble, disassemble and carry. Background Art

[0002] Air-energy water heaters, also known as air source heat pump water heaters, are highly efficient and energy-saving and are widely used in household, industrial, construction, food and pharmaceutical manufacturing and other fields. At present, air-energy water heaters at construction sites are generally installed directly on the ground with multiple bolts, but the construction site is dusty and the ground is relatively humid, which can easily cause the bolts to rust, making it difficult to remove the bolts and inconvenient to install and disassemble the water heater. In addition, when installing and disassembling the water heater, it is necessary to manually install and disassemble the bolts one by one, which is cumbersome, time-consuming and labor-intensive.

[0003] The Chinese patent with the publication number CN219550832U discloses an air-energy water heater that is easy to install. The water heater body is inserted and positioned on the base by setting mutually plug-in matching mounting blocks and mounting grooves. The threaded rod in the base is rotated to drive the moving block threaded thereon to reciprocate along the axial direction of the threaded rod. The moving block drives the clamping block into the clamping groove so that the clamping block and the clamping groove are clamped to complete the positioning and installation of the air-energy water heater body. Although this patent simplifies the assembly and disassembly of the water heater body to a certain extent, the operation steps are relatively cumbersome. During the transportation process of the water heater body, it still needs to be manually lifted up for transportation. The labor intensity of manual transportation is large and wastes manpower.

[0031] When the water heater body 1 is fixedly placed on the installation table, the base 2 is in direct contact with the installation table, and the caster 5 is completely located in the installation space 21. When transporting the water heater body 1, the active shaft 4 is rotated, and the active shaft 4 drives the rotating plate 41 to rotate synchronously, and the rotating plate 41 drives the connecting rod 33 to move downward, and the connecting rod 33 drives the two connecting rods 32 to swing downward synchronously around the hinge shafts connected to the frame 31 at their upper ends, and the connecting rod 32 drives the caster 5 connected thereto to swing downward until the caster 5 swings downward from the installation space 21 to protrude from the bottom surface of the base 2 to support the base 2 in the air, and the positioning mechanism 6 is adjusted to fasten the active shaft 4 to the base 2, and the active shaft 4 cannot rotate at this time.
