Problems solved by technology

The traditional sensor electrical box has poor waterproof performance, and the moisture in the air can easily enter the electrical box, causing condensation to occur on the side of the electrical box close to the evaporator during cooling, and the moisture and condensation entering the electrical box will further damage the sensor installation circuit. The plate causes corrosion, which affects the inspection accuracy and service life of the sensor and the safe operation of the whole machine

Abstract

The invention discloses a sensor electric appliance box for accommodating a sensor circuit board. The sensor electric appliance box comprises a base, a top cover and a seal ring. A base support is arranged on the base, the sensor circuit board is fixed on the base through the base support, and a preset distance is reserved between the sensor circuit board and the base. The top cover is provided with an air through hole. The seal ring is matched with a sensor welded on the sensor circuit board in shape, tightly connected onto the sensor in a sleeved mode and wraps a welding position between the sensor and the sensor circuit board. When the top cover is buckled with the base, the seal ring tightly adheres to the periphery of the air through hole in the top cover. The sensor electric appliance box is good in waterproof performance, does not easily produce condensation, does not influence the sensor inspection accuracy, greatly prolongs the service life of the sensor and greatly improves the running safety performance of a whole machine.

Description

technical field [0001] The invention relates to the technical field of electrical component protection, in particular to a sensor electrical box. Background technique [0002] With the development of air-conditioning technology, people have higher and higher requirements on the indoor environment humidity control of household air-conditioners, and sensors are more and more widely used in the field of air-conditioning. The traditional sensor electrical box has poor waterproof performance, and the moisture in the air can easily enter the electrical box, causing condensation to occur on the side of the electrical box close to the evaporator during cooling, and the moisture and condensation entering the electrical box will further damage the sensor installation circuit. The plate causes corrosion, which affects the inspection accuracy and service life of the sensor and the safe operation of the whole machine. Contents of the invention [0003] Based on this, it is necessary t...
