Description

Technical Field

[0001] The utility model relates to the technical field of integrated control panels, in particular to an electric control device for a chiller with an integrated control panel. Background Art

[0002] The chiller's electronic control unit is a key component of the chiller. It primarily consists of a controller, various sensors and actuators, and a human-machine interface. The controller receives signals from sensors such as temperature, pressure, and water flow to precisely control actuators like the compressor, pump, and fan to achieve stable cooling. It also features fault diagnosis capabilities, providing timely alerts and protective measures when anomalies occur. The human-machine interface allows users to easily set parameters and view operating status and fault information. The chiller's electronic control unit ensures efficient, stable, and safe operation of the chiller.

[0003] In the prior art, the device lacks protection for the main control board. No protective device is provided for the components of the main control board inside the device. Under human influence, the components are easily damaged, thereby reducing the service life of the main control board. Utility Model Content

[0004] The purpose of the utility model is to provide an electric control device for a chiller with an integrated control panel. By adopting the device to work, the problem that the device lacks protection for the main control panel and the parts of the main control panel are not provided with protective devices inside the device, which can easily cause damage under human influence, thereby reducing the service life of the main control panel.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a chiller electric control device with an integrated control panel, comprising a main control box, a housing 1 being rotatably mounted on one side of the main control box, a main control panel being mounted inside the housing 1, a protective shell assembly being rotatably mounted on the side of the main control panel close to the main control box, the protective shell assembly being sleeved on the outside of the main control panel, the protective shell assembly comprising a protective shell, four groups of connecting blocks 1 being fixedly mounted on the upper end of the protective shell, a rotating shaft being fixedly mounted between two adjacent groups of connecting blocks 1, a rotating tube being rotatably mounted on the outer side of the rotating shaft, the lower end of the rotating tube being connected to the main control panel Fixed connection, the lower end of the protective shell is fixedly installed with a connecting block 2, and a card block is fixedly installed on the side of the connecting block 2 close to the main control board. A buckle 1 is fixedly installed on the outside of the card block, and one end of the buckle 1 is fixedly connected to the main control board. Since personnel need to open the shell 1 many times for operation, it is easy to cause damage to the parts inside the main control board, so we protect it through a protective shell assembly. When we need to inspect the parts of the main control board, we open the protective shell by pushing away the card block and inspect it. After the inspection is completed, the card block and buckle 1 are fixed to complete the protection.

[0006] Preferably, the main control box includes a shell two, two groups of cable tubes one are installed inside the shell two, two groups of cable tubes two are installed inside the shell two, the two adjacent groups of cable tubes one are vertically distributed with the cable tubes two, the cable tube one is fixedly installed with the wire one, and the ends of the cable tube one and the cable tube two away from the shell one are fixedly installed with partitions, and different wires are arranged through the cable tube one to prevent accidents caused by entanglement of various wires, and the main control box is protected from moisture and humidity by the partitions.

[0007] Preferably, an integrated board is fixedly installed inside the second shell, a switch is installed on one side of the integrated board, the switch is fixedly connected to the partition, and a hole is opened at the lower end of the second shell.

[0008] Preferably, a fuse is slidably installed inside the integrated board, and an elastic guide is fixedly installed at the lower end of the fuse. The device will automatically protect itself when encountering excessive current or voltage. When replacing the fuse, it is only necessary to pull out the fuse and replace it. Traditionally, it takes more than ten minutes to replace a thermal protector, which greatly increases the convenience of the device.

[0009] Preferably, a baffle is installed at the upper end of the shell one, and the baffle matches the shell two. A clip two is fixedly installed on the inner side of the shell one, and a wire two is installed on the inner side of the clip two.

The main control board is connected to the integrated board through the wire two, and the wire two is fixed inside the device through the clip two.

[0010] Preferably, the shell one includes two groups of connecting blocks three, which are fixedly connected to the shell one, and a rotating column is fixedly installed between the two groups of connecting blocks three. Two groups of connecting rings are rotatably installed on the outer side of the rotating column, and the outer side of the connecting ring is fixedly connected to the shell two.

On the side of the connecting block two close to the main control board, a clamping block is fixedly installed. Outside the clamping block, a buckle one is fixedly installed. One end of the buckle one is fixedly connected to the main control board. Since it is necessary to open the housing one multiple times during personnel operation, it is easy to damage the parts inside the main control board.
