Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an explosion-proof intelligent variable frequency water-cooled air conditioner. Background Art

[0002] Common air conditioners can achieve a good cooling effect under the action of refrigerants and refrigerators. With the increasing requirements for environmental protection and energy conservation, water-cooled air conditioners have gradually become popular. The working principle of water-cooled air conditioners is mainly based on the cooling effect of water evaporation. In places containing explosive gas mixtures, such as production workshops, control rooms, laboratories, warehouses, gas stations and other places, there are certain requirements for the explosion-proof performance of water-cooled air conditioners.

[0003] At present, explosion-proof water-cooled air conditioners commonly used in factories, workshops and other places will take certain explosion-proof measures on the internal fan motor to ensure the normal operation of the water-cooled air conditioner. However, when the place of use is large, the air outlet of the water-cooled air conditioner needs to swing so that the cooled air can be blown to a larger range. The realization of this function is based on another motor dedicated to controlling the swing of the air outlet. Because of the limited space of the installation location, this motor often lacks explosion-proof treatment. Using it in a place containing explosive gas mixtures may cause damage to the motor and affect the overall use of the water-cooled air conditioner. For this reason, it is necessary to design an explosion-proof water-cooled air conditioner that is more suitable for use in the working environment of explosion-proof equipment, has stable performance, and has a long product life, so as to solve the problem that the motor of the explosion-proof water-cooled air conditioner is easily damaged due to the working environment when adjusting the direction of the air outlet.

After the swing motor 2 is started, the swing motor 2 drives the blades of the louver assembly to swing and deflect through the transmission assembly.

[0028] The transmission assembly includes a motor transmission shaft 6, a gear transmission mechanism 8, and an eccentric transmission member 17. The bottom end of the motor transmission shaft 6 passes through the explosion-proof housing of the explosion-proof motor group and is connected to the swing motor 2.

The output end of the gear transmission mechanism 8 is connected to the eccentric transmission member 17 through an output shaft 7. The gear transmission mechanism 8 is composed of multiple gears. The gear transmission mechanism 8 includes an input gear, a transmission gear, and an output gear. The motor transmission shaft drives the input gear to rotate, and the multiple gears mesh with each other. The input gear drives the output gear to rotate through the transmission gear, and drives one end of the output shaft 7 and the eccentric transmission member 17 to rotate. Specifically, the input gear is provided with an input end, and the motor transmission shaft 6 is fixedly connected to the input end of the input gear (refer to the appendix Figure 7 ), or the motor transmission shaft is connected to the input end of the input gear through an input shaft (refer to the appendix Figure 8 ). The output gear has an output end, and the eccentric transmission member 17 is connected to the output end of the output gear through the output shaft 7. Among them, the output shaft and the eccentric transmission member can be an integral eccentric transmission shaft, or the output shaft and the eccentric transmission member are of a split structure. A groove 18 is provided at the top of the eccentric transmission member 17, and one end of the output shaft 7 is fixedly connected to the transmission member 17 through the groove 18, and the other end of the output shaft is connected to the output end of the output gear.

[0029] The louver assembly includes a connecting rod and a plurality of blades sequentially connected to the connecting rod. The blades are respectively connected to the connecting rod 15 through a rotating shaft 9. A transmission groove 16 is provided on the connecting rod 15. The bottom of the eccentric transmission member 17 is placed in the transmission groove 16. When the motor transmission shaft 6 rotates, it is transmitted to the gear transmission mechanism 8, and is transmitted by the gear transmission mechanism 8 to the output shaft 7 to drive the eccentric transmission member 17 to rotate in the transmission groove 16, so that the connecting rod 15 makes a reciprocating linear motion, thereby driving the swing of the blades.

[0030] An opening is provided at the upper end of the position of the swing motor 2 in the explosion-proof housing. The opening is connected to a threaded flameproof joint surface 13. The motor transmission shaft 6 passes through the threaded flameproof joint surface 13 and is connected to the swing motor 2.

[0031] The air conditioner body includes an air conditioner box 12 and a base 11. The air outlet assembly is installed inside the air conditioner box 12, and the explosion-proof motor set is fixed inside the air conditioner box 12 through a motor base 10. The motor base 10 is arranged on one side of the air conditioner box 12 near the air outlet.

[0032] The explosion-proof housing consists of a front cover, a housing, and a rear cover 5. A motor mounting bracket is provided inside the rear cover 5.

The driving motor 3 drives the fan 1 to rotate, absorbs the hot air into the water-cooled air conditioner, and after being cooled by the cooling system of the water-cooled air conditioner, blows out from the other end. According to the indoor air circulation situation, adjust the air volume of the water-cooled air conditioner, and turn on the swing function of the louvers according to the working environment requirements. At this time, the swing motor 2 at the rear cover of the housing starts, the swing motor 2 drives the motor transmission shaft 6 to rotate, the motor transmission shaft 6 drives the gear transmission mechanism 8 to operate. After being transmitted through the input gear, the transmission gear, and the output gear in sequence, the output shaft 7 rotates. The output shaft 7 is fixedly connected to the eccentric transmission member 17, driving the eccentric transmission member 17 to rotate around the output shaft 7 as the axis. The lower part of the eccentric transmission member 17 begins to rotate around the center of the circle. When the eccentric transmission member 17 turns to one side, the transmission slot 16 on the louver connecting rod 15 also offsets to the same side as the eccentric transmission member 17. The elliptical design of the transmission slot 16 gives the eccentric transmission member 17 space to move in the up and down directions when rotating, enabling the connecting rod 15 of the louver to reciprocate only in the left and right directions, driving the louver blades to swing left and right around the louver rotating shaft 9, thereby realizing the swing function of the air outlet of the water-cooled air conditioner. In this solution, the originally externally placed motor and the driving motor separately used to drive the louver swing are assembled into one motor, and the combined motor is explosion-proof treated to meet the standard GB / T3836, so that the explosion-proof intelligent variable-frequency water-cooled air conditioner can ensure the normal operation of the two groups of motors in a workplace containing explosive gas mixtures and improve the service life of the product.
