Utility model content

The utility model provides a PLC control cabinet, which can automatically adjust the temperature and humidity inside the cabinet, has safe and reliable operation, and improves the service life of the PLC control cabinet.

The utility model provides a PLC control cabinet, comprising: a cabinet body and a cabinet door arranged on the cabinet body and movably connected with the opening side of the cabinet body; the upper side of the cabinet body is provided with an air outlet; There is an air inlet, a display screen and an electrical switch are installed on the cabinet door, and a temperature and humidity control module, a temperature sensor, a humidity sensor, an exhaust fan and a dehumidification module are installed inside the cabinet. At the tuyere, the temperature and humidity control module is connected to the power supply through an electrical switch, and the temperature sensor, humidity sensor, display screen, exhaust fan and dehumidification module are respectively electrically connected to the temperature and humidity control module.

Further, dust-proof gaskets are provided around the opening of the cabinet body, and the cabinet door is fastened with the cabinet body through the dust-proof gaskets.

Furthermore, the bottom of the cabinet body is provided with a plurality of rollers with positioning function, and the plurality of rollers with positioning function are detachably connected with the cabinet body.

Further, dust-proof filters are provided on the inner surfaces of the air inlet and the air outlet.

Compared with the prior art, the utility model has the beneficial effects of:

1) Use the temperature sensor to detect the temperature inside the cabinet. When the temperature is higher than the set temperature, the temperature and humidity control module controls the rotation of the exhaust fan to perform air circulation and cool down. When the humidity sensor detects that the humidity in the cabinet exceeds the set humidity , The temperature and humidity control module controls the dehumidification module to dehumidify to ensure that the temperature and humidity are within the controllable range, avoiding the damage of the high temperature and high humidity air in the PLC cabinet to the components of the PLC control cabinet, and prolonging the service life of the PLC control cabinet.

2) The dust-proof gasket prevents dust from entering the cabinet from the cabinet door, which affects the heat dissipation of components in the cabinet.

3) The roller with positioning function makes the PLC control cabinet easy to move and saves time and effort.

4) There are dust-proof filters at the air inlet and outlet to prevent dust from entering the cabinet due to air circulation and affecting the heat dissipation of components.

detailed description

A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

As shown in Fig. 1 and Fig. 2, a kind of PLC control cabinet provided by the embodiment of the utility model includes: a cabinet body 1 and a cabinet door 2 arranged on the cabinet body 1 and movably connected with the opening side of the cabinet body 1, The upper side of the cabinet 1 is provided with an air outlet 5, the lower side of the cabinet 1 is provided with an air inlet 4, the cabinet door 2 is provided with a display screen 3 and an electrical switch 6, and the inside of the cabinet 1 is provided with a temperature and humidity control module, Temperature sensor, humidity sensor, exhaust fan 7 and dehumidification module, the exhaust fan is arranged in the cabinet 1 facing the air outlet 5, the temperature and humidity control module is connected to the power supply through the electrical switch 6, the temperature sensor, humidity sensor, display screen 3. The exhaust fan 7 and the dehumidification module are respectively electrically connected to the temperature and humidity control module.

The temperature in the cabinet 1 is detected by the temperature sensor. When the temperature is higher than the set temperature, the temperature and humidity control module controls the rotation of the exhaust fan 7, the cold air enters from the air inlet 4, and the hot air is discharged from the air outlet 5 through the exhaust fan 7. Perform air circulation to achieve cooling. When the humidity sensor detects that the humidity in the cabinet 1 exceeds the set humidity, the temperature and humidity control module controls the dehumidification module to perform dehumidification to ensure that the temperature and humidity are within the controllable range and avoid high temperature and high humidity air from controlling the PLC. The components of the cabinet cause damage, prolonging the service life of the PLC control cabinet, and displaying the temperature and humidity in the cabinet 1 through the display screen 3 .
