Description

Technical Field

[0001] This utility model relates to the field of variable frequency compressor technology, specifically to a variable frequency compressor controller with dustproof function. Background Technology

[0002] A variable frequency compressor can be divided into two parts: a variable frequency controller, commonly known as a frequency converter, and the compressor itself. The variable frequency controller works by converting alternating current (AC) from the power grid into square wave pulses. By adjusting the frequency of these square wave pulses (i.e., adjusting the duty cycle), the speed of the motor driving the compressor can be controlled. Higher frequencies result in higher speeds.

[0003] Variable frequency compressors require a controller during operation. For example, a Chinese patent discloses a DC variable frequency compressor controller mounting box and refrigeration equipment (Publication No.: CN207439000U). The DC variable frequency compressor controller mounting box includes a main body and a cover. The mounting box has a receiving cavity for mounting the main control board. The cover is detachably mounted on the opening end of the mounting box. The main body of the mounting box has a heat dissipation part and a connection port, which are positioned opposite each other on the side wall of the main body. This invention aims to alleviate the technical problem of poor heat dissipation in the mounting box, leading to a reduced lifespan of the circuit board inside. While this patent alleviates the problem of poor heat dissipation in the mounting box, it does not prevent dust accumulation on the controller. This means that the controller surface is easily contaminated with dust during use, failing to protect it and allowing external dust to easily settle on the controller surface. Utility Model Content

[0028] As a technical optimization of this utility model, by setting up controller 1, the variable frequency compressor can be controlled. The user controls the chassis 101 to issue commands according to button 103, so that the chassis 101 issues specific commands to the variable frequency compressor, and then the status of the variable frequency compressor is displayed on the display screen 102 on the chassis 101.

[0029] refer to Figure 1 The dustproof mechanism 2 includes a casing 21. Both sides of the top of the casing 21 are hinged to a top protective casing 22. The front of the top protective casing 22 is hinged to a front protective casing 23. The interior of the casing 21 is fixedly connected to the chassis 101. The bottom of the top protective casing 22 contacts the top of the chassis 101. The front of the front protective casing 23 is fixedly connected to a transparent glass 24.

[0030] As a technical optimization of this utility model, by setting up a dustproof mechanism 2, the chassis 101 can be protected. The user installs the chassis 101 inside the protective shell 21, which protects the sides, bottom and back of the chassis 101. Then, the top of the chassis 101 is protected by the top protective shell 22, and the front of the chassis 101 is protected by the front protective shell 23.

[0037] The working principle and usage process of this utility model are as follows: In use, the user installs the chassis 101 inside the protective shell 21, which covers and protects the sides, bottom, and back of the chassis 101. Then, the user pushes down the push rod 31. The push rod 31 drives the transmission shaft 33 downwards via the lifting plate 32. Simultaneously, the lifting plate 32 compresses the return spring 5. The transmission shaft 33 causes the top of the transmission plate 34 to move downwards in a circular motion around the connecting block 4. The transmission plate 34 drives the lifting frame 36 downwards via the transmission rod 35. The lifting frame 36 drives the connecting bearing 37 downwards. The connecting bearing 37 drives the rotating shaft 38 downwards. The rotating shaft 38 drives the clamping plate 39 downwards to contact the top of the chassis 101. Finally, the top protective shell 22 is placed over the top of the chassis 101, so that the mating hole 6 fits onto the clamping plate 39. The surface is then released, and the push rod 31 is released. The lifting plate 32 is reset by the reset spring 5. The lifting plate 32 is reset by the transmission shaft 33, which drives the top of the transmission plate 34 to move upward in a circular motion around the connecting block 4. The transmission plate 34 is reset by the transmission rod 35 and the lifting frame 36. The connecting bearing 37 is reset by the rotating shaft 38, which drives the clamping plate 39 to reset, so that the clamping plate 39 passes through the mating hole 6 and moves to the top of the mating hole 6. Then the clamping plate 39 is rotated ninety degrees so that the clamping plate 39 contacts the top of the top protective shell 22 and fixes the top protective shell 22. The top protective shell 22 wraps and protects the top of the chassis 101 to prevent the top of the chassis 101 from getting dusty. The front protective shell 23 wraps and protects the front of the chassis 101 to prevent the front of the chassis 101 from getting dusty.

[0038] In summary, this variable frequency compressor controller with dustproof function, by setting the connecting mechanism 3, can fix the dustproof mechanism 2 on the top of the controller 1, and protect the controller 1 by preventing the controller 1 from getting contaminated with external dust. When the user uses it, the surface of the controller will not be contaminated with various dusts, thus protecting the controller and preventing external dust from easily falling onto the surface of the controller.
