Fresh food express ark for smart community

Abstract

The invention discloses a fresh food express ark for a smart community. The fresh food express ark comprises a transformer and a control board independent of the outside of the transformer, wherein the control board is connected with a power supply source; and the control board is connected with the transformer and is used for providing the transformer with a power supply. According to the fresh food express ark, after-sales maintenance facilitation is achieved through separating the control board from the transformer, the transformer is provided with the electricity through the control board, power supply for a whole machine through a single power line is achieved, and the defect of relatively large volume of an existing integrated transformer is changed.

Description

technical field [0001] The invention relates to circuit technology, in particular to a fresh express cabinet for an intelligent community. Background technique [0002] Figure 1 to Figure 3 The schematic diagrams of the fresh express cabinets in the smart community in the prior art are respectively shown, wherein, figure 1 The fresh express cabinet shown includes two transformers, each of which is connected to its own power supply, and control boards are integrated in the two transformers to realize the power supply to the compressor, the main engine and other electrical loads. However, the above-mentioned transformer is very large in size, takes up a large space, and has very high requirements on the installation environment. It needs two sockets to take power, and it is very inconvenient to connect the power supply outside. [0003] For this reason, people in the industry improve the above-mentioned fresh express cabinet, such as figure 2 As shown, the transformer 1 i...

Problems solved by technology

Should figure 2 The structure shown simplifies the circuit of the power connection part, but due to the integration of the transformer and the control board, its volume is very large and takes up space

[0004] In addition, the industry also provides a image 3 The fresh express cabinet shown uses a large transformer integrated with a control board and transformer to realize the working power supply for the compressor, host and other electrical loads. The above-mentioned transformer is very large and takes up space

[0005] the above Figure 1 to Figure 3 The transformer of the fresh express cabinet shown uses the transformer integrated control board. When the transformer integrated control board fails, the maintenance is more complicated.
