Description

Technical Field

[0001] The utility model belongs to the technical field of air energy water heaters, and particularly relates to a frequency conversion controller for air energy water heaters which is convenient for wiring. Background Art

[0002] An air-energy water heater uses a small amount of electricity to drive a compressor, which absorbs large amounts of heat from the air to heat the water. Its operating principle is similar to that of an air conditioner, but it primarily produces heat, saving significant amounts of electricity. The variable frequency controller used in air-energy water heaters primarily controls the operation of the compressor, achieving more energy-efficient, efficient, and stable heating. The variable frequency controller automatically adjusts the compressor speed based on factors such as water temperature, water pressure, and ambient temperature, thereby varying the heat output and stabilizing the water temperature while also reducing unnecessary energy consumption.

[0003] When installing the frequency conversion controller, it is necessary to connect it to the air-to-water heater through wiring to achieve control. However, in the existing practice, wiring is generally done through a terminal board. When connecting, the wire is inserted into the wiring slot, and then a tool such as a screwdriver is used to tighten the screw to complete the wiring operation.

[0004] However, this requires a screwdriver of a special size for installation. If you cannot find a special screwdriver, you cannot install it. At the same time, you still need to use a screwdriver to disassemble it during disassembly, which not only wastes time but also increases people's labor.

[0005] To this end, we have proposed a variable frequency controller for air-energy water heaters that is easy to wire. It not only does not require tools to install and remove the wires, saving time and effort, but also protects the connecting wires, making it easier for people to operate. Utility Model Content

[0006] The purpose of this utility model is to provide a lithium battery positive electrode functional dispersant homogenizing device, which can not only achieve the effect of quantity control, but also enable the material to form a standard particle size, thereby improving the quality of the lithium battery positive electrode slurry.

[0007] The technical solutions adopted in this application are as follows:

[0008] A frequency conversion controller for an air-energy water heater that is easy to connect, comprising a mounting plate, a frequency conversion controller body being arranged on the mounting plate, a protective housing being mounted on one side of the frequency conversion controller body, and a wiring assembly being arranged inside the protective housing;

[0009] The wiring assembly includes a wiring board, a rotating assembly is provided on the wiring board, a connecting block is provided on the rotating assembly, a plurality of wiring slots are provided on the wiring board, a conductive plate is fixedly provided on the inner wall of the wiring slot, and a wire pressing plate is movably provided, and one side of the wire pressing plate is connected to the connecting block;

[0010] A first semicircular protective plate is fixedly provided on one side of the conductive plate, and a second semicircular protective plate is fixedly provided on one side of the wire pressing plate.

[0011] Furthermore, a plurality of mounting holes are provided on the mounting plate.

[0012] Furthermore, the rotating assembly includes a first gear located at the top of the terminal block, a threaded rod is installed at the bottom of the first gear, the bottom of the threaded rod passes through the terminal block and is located inside the terminal slot, and the connecting block is sleeved on the threaded rod. A second gear is also rotatably set on the top of the terminal block, the second gear is engaged with the first gear, and a manual rotating rod is set on the top of the second gear.

[0013] Furthermore, a first through hole and a second through hole are formed on the protective shell, the first through hole corresponds to the second gear, and the second through hole corresponds to the positions of the first semicircular protective plate and the second semicircular protective plate.

[0014] Furthermore, the first semicircular protective plate and the second semicircular protective plate are both provided with a first anti-slip surface.

[0015] Furthermore, a second anti-slip surface is provided on the wire pressing plate.

[0016] The technical effects achieved by this utility model are:

[0017] First, the wire is put into the corresponding wiring slot, and then people only need to rotate the manual rotating rod, which drives the second gear to rotate the first gear, and the first gear drives the threaded rod to make the connecting block drive the wire pressing plate to move down, thereby pressing the wire to achieve the effect of quick wiring. At the same time, the first semicircular protective plate and the second semicircular protective plate can protect the wire when they are merged to prevent damage to the wire due to bending. When disassembling, no tools are needed. Only the manual rotating rod needs to be rotated in the opposite direction. The manual rotating rod drives the second gear to rotate the first gear, and the first gear drives the threaded rod to make the connecting block drive the wire pressing plate to move up, so that the wire can be taken out and quickly disassembled. This device not only does not require tools for installing and disassembling the wire, but also can protect the connecting wire, making it convenient for people to operate.
