Refrigerator freezer leak detection room

Abstract

The invention discloses a refrigerator freezer leak detection room, and relates to the technical field of household appliance leak detection. The leak detection room comprises a leak detection room body and a controller; the leak detection room body comprises four stand columns, side plates, a bottom plate and a top plate; an electric sliding block is arranged on the top plate; an air supply fan is arranged on the top plate; a bearing mechanism is arranged on the bottom plate; a pressure sensor is arranged on the bearing mechanism; moving mechanisms are arranged at the bottom ends of the fourstand columns; an illuminating lamp, a leak detection device and a human body induction module is further arranged on the leak detection room body; the signal receiving end of the controller is connected with the human body induction module and the pressure sensor; the signal output end of the controller is connected with the illumination lamp and the air supply fan; and a speed change control module is arranged between the controller and the air supply fan. The moving mechanisms and a moving system of the electric sliding block are arranged on the leak detection room body; the leak detectionroom is movable; and meanwhile, air supply pipelines are arranged on the stand columns for supplying air, so that the three-dimensional air supply is achieved, and the air supply effect is good.

Description

technical field [0001] The invention belongs to the technical field of leak detection of home appliances, in particular to a leak detection room for refrigerators and freezers. Background technique [0002] Household appliances are an indispensable part of daily life. Refrigerators and freezers have penetrated into thousands of households. Leak detection is an important process in the process of producing refrigerators and freezers, which is directly related to the quality and quality of products. Therefore, the leak detection room is of considerable importance in the manufacturing process of refrigerator freezers. However, the current leak detection room generally does not have an air supply system or a fixed-speed flat air supply system. If there is no air supply system, it will affect the sensitivity of the detection probe, thereby affecting the accuracy of the detection. The air supply effect of the fixed-speed planar air supply system is not ideal at first, and the ene...

Problems solved by technology

However, the current leak detection room generally does not have an air supply system or a fixed-speed plane air supply system. If there is no air supply system, it will affect the sensitivity of the detection probe, thereby affecting the accuracy of detection.

The air supply effect of the fixed-speed planar air supply system is not ideal at first, and the energy consumption is relatively large

At the same time, the detection conditions of the leak detection probe are not ideal, and the gas environment at the detection probe is not cleaned, which will reduce the detection accuracy and detection accuracy of the detection probe

In addition, the leak detection rooms currently used are all fixed and cannot be moved after the construction is completed. When the production line is rebuilt or part of the production line is renovated, there is a risk that the normal production will be affected because the leak detection room cannot be moved.

In addition, the leak detection room uses opaque walls, and inspection personnel or other inspection personnel cannot observe the internal conditions of the leak detection room in real time, which is not conducive to quality control
