Detailed Description

The following describes in detail specific embodiments of the present invention. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

As shown in fig. 1, the present invention provides an electrical cabinet with a self-adjusting function, which includes a cabinet body 1, an environment monitoring device and an adjusting device disposed in the cabinet body 1, and a control unit; wherein the content of the first and second substances,

at least two monitoring intervals are formed inside the cabinet body 1 from inside to outside, and the environment monitoring equipment is arranged in each monitoring interval;

The cabinet body 1 is divided into two monitoring sections in a targeted mode by the whole electrical cabinet, so that the sections with more electrical elements and the relatively empty sections are divided in a differentiated mode, the internal environment of the electrical cabinet is monitored on the basis, the adjusting equipment is controlled in a targeted mode according to the monitoring result to adjust, and the overall environment adjusting effect can be effectively improved.

The monitoring interval here can be a plurality of, certainly, in order to reach effectual regulation and control effect under the prerequisite of cost reduction as far as possible, in a preferred embodiment, the monitoring interval includes from inside to outside first monitoring area 2 and the second monitoring area 3 that sets up in order, just drying mechanism is including the first heater that is arranged in first monitoring area 2 and the second heater that is arranged in second monitoring area 3, just the first heater with be formed with separation blade 4 between the second heater, be formed with louvre 5 on the separation blade 4.

Here, the first heater and the second heater may be disposed around the inside of the first monitoring section 2 and the second monitoring section 3, respectively. For example, a second heater in the second monitoring zone 3 may be provided around the inner wall of the cabinet 1.

In a further preferred embodiment, in order to effectively discharge the water vapor formed after drying and heating, the drying mechanism further comprises a dehumidifying fan 6 located on the cabinet 1.

In a more preferred embodiment, the cooling mechanism comprises heat dissipating fins 7 extending from the first monitoring zone 2 towards the second monitoring zone 3, and a blowing assembly 8 located in the second monitoring zone 3. Through the heat conduction and transmission of the heat radiating fins 7, the heat is effectively radiated based on the mode that the external blowing assembly 8 blows air. It should be noted that the blowing assembly 8 herein may form a plurality of blowing openings, so as to better meet the requirement of multi-directional blowing heat dissipation.

Here, the threshold value is set in a targeted manner and entered into the control unit as a function of the external environment, so that a better control and adjustment can be made as a function of the external environment.

Further, in order to adjust the inside of the device in a targeted manner, avoid the adjustment rationality problem caused by the difference between the first monitoring area and the second monitoring area, and avoid the asynchronism between the inside and the outside after adjustment caused by one threshold, in a preferred embodiment, in the adjustment process, in step S200, a plurality of temperature and humidity thresholds are set, for example, at least including a priority temperature value, a stable temperature value, a priority humidity value, and a stable humidity value; and the number of the first and second electrodes,

the value of the priority humidity value is higher than that of the stability humidity value.

In the targeted adjustment of the temperature, when at least one of the temperatures in the two monitoring intervals is greater than the priority temperature value, the air blowing assembly is started to complete the whole air blowing circulation heat dissipation, so that the temperature is reduced integrally;

when the temperature in the internal monitoring interval is greater than the stable temperature value and less than the priority temperature value, the second heater is started to a first preset time, and then the blowing assembly is started. This way, the second monitoring zone 3 can be preheated in priority, avoiding a sharp increase in humidity during a sharp decrease in temperature.

Normally, the temperature of the inner monitoring zone is higher than that of the outer monitoring zone, and the inner monitoring zone is also the working position of the electrical component. Through the adjustment, the targeted stepwise adjustment can be performed, and the problems that electrical components are easy to damage and the like due to sudden change in a rapid adjustment state are avoided.

In a specific manner, in the humidity adjusting process, when the humidity in the two monitoring areas is greater than the priority humidity value or the humidity in the first monitoring area is greater than the priority humidity value, the first heater and the second heater are synchronously started.

When the humidity of the first monitoring area is between the priority humidity value and the stable humidity value and the humidity of the second monitoring area is greater than the stable humidity value, the first heater is started for a second preset time, and then the second heater is started. Similarly, the heating mode is to evaporate the internal moisture to the outside in advance and then perform the overall evaporation, so as to avoid the problems that the evaporation of the internal moisture is slow and the overall temperature is very high during the synchronous opening. Of course, the dehumidifying fan may be turned on synchronously to perform the dehumidifying operation, and the turning on time of the dehumidifying fan may not be limited.

Furthermore, when the humidity of the first monitoring area is lower than the stable humidity value and the humidity of the second monitoring area is higher than the stable humidity value, the dehumidifying fan is started for a third preset time, and then the second heater is started. By the mode, the internal electrical components can be prevented from being heated additionally while the whole body can be effectively dehumidified.

In the temperature and humidity regulation, the two paths can be two parallel paths and are synchronously carried out, and certainly, in order to avoid further increasing the burden on the temperature regulation in the dehumidification process, the humidity regulation is carried out at least after the temperatures in the first monitoring area and the second monitoring area are respectively not higher than the priority temperature value.

The preferred embodiments of the present invention have been described in detail, however, the present invention is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present invention within the technical idea of the present invention, and these simple modifications are within the protective scope of the present invention.

It should be noted that the various technical features described in the above embodiments can be combined in any suitable manner without contradiction, and the invention is not described in any way for the possible combinations in order to avoid unnecessary repetition.

In addition, any combination of the various embodiments of the present invention is also possible, and the same should be considered as the disclosure of the present invention as long as it does not depart from the spirit of the present invention.
