Description

Technical Field

[0001] This utility model relates to the technical field of condensate drainage equipment, specifically an evaporator condensate drainage device. Background Technology

[0002] In modern air conditioning systems, the evaporator, as the core component of the refrigeration cycle, continuously condenses moisture from the air on its surface due to the low-temperature effect during the cooling process, forming condensate. If this condensate is not drained in a timely and effective manner, it will not only accumulate inside the equipment, breeding mold and bacteria and affecting air quality, but may also overflow into the indoor environment. Therefore, the smooth drainage of condensate is an important guarantee for the stable operation of the air conditioning system.

[0003] The shortcomings of existing technology:

[0004] Currently, the condensate drainage system commonly used in the air conditioning industry relies primarily on gravity-fed drainage structures. This involves collecting condensate in a tilted drip tray and then naturally draining it outdoors through a drain pipe. Some mid-to-high-end models are equipped with filters or dust covers at the drain outlet to reduce the entry of dust, fibers, and other impurities into the drainage channel. However, existing technologies still have certain shortcomings. Over time, the drain holes inevitably become clogged with dust and other contaminants. Traditional drainage systems lack an active unclogging mechanism, relying solely on reactive measures after blockage occurs. This typically requires manual disassembly of the casing for cleaning, which is not only complex but can also damage the equipment or reduce its sealing performance due to improper disassembly.

[0035] Please refer to Figures 1-5 As shown in the drawings, the utility model provides a kind of evaporator condensate water drainage device technical scheme: a kind of evaporator condensate water drainage device, including shell 1, evaporator 2 is installed in one side of the inside of shell 1, fan barrel 3 is installed in the side of the inside of shell 1 away from evaporator 2, the inside of shell 1 is located below evaporator 2 and fan barrel 3 and is equipped with isolating cover 4, drainage assembly 5 is installed in the lower side of isolating cover 4 below evaporator 2, drainage assembly 5 is installed for dredging the blocking mechanism 6 of drainage assembly 5 below shell 1, controller 7 is also installed on the lower end surface of the inside of shell 1;

[0036] The unblocking mechanism 6 comprises a negative pressure pipe 601, a dust collecting box 604, an extendable pipe 606 and a horizontal driving mechanism 608. The negative pressure pipe 601 is movably installed above the drain hole of the drain assembly 5, and a permanent magnet 602 is installed at the end of the negative pressure pipe 601. An electromagnet 603 matching the permanent magnet 602 is installed on the lower inner wall of the shell 1, and the horizontal movement of the negative pressure pipe 601 is controlled by the attraction and repulsion of the electromagnet 603 to the permanent magnet 602. The dust collecting box 604 is installed on the lower end surface of the shell 1, and a hose 605 is connected between the connecting pipe of the air inlet end of the dust collecting box 604 and the negative pressure pipe 601. The extendable pipe 606 is slidably connected to the connecting pipe of the air outlet end of the dust collecting box 604, and a fan cover 607 is formed at the end of the extendable pipe 606. The fan cover 607 is slidably connected to the air inlet at the lower end of the shell 1. The horizontal driving mechanism 608 is installed at the lower end of the shell 1 to drive the horizontal movement of the extendable pipe 606.

[0037] When the air conditioner is working, the fan cylinder 3 is started, and the air flow enters from the air inlet below the fan cylinder 3 of the shell 1 to the evaporator 2, and the condensate water generated by the evaporator 2 falls and gathers into the drain assembly 5. When the drain hole of the drain assembly 5 is blocked, the controller 7 controls the electromagnet 603 to be powered to generate repulsion to the permanent magnet 602, thereby pushing the input end of the negative pressure pipe 601 to move above the drain hole. Then the horizontal driving mechanism 608 is started to control the horizontal movement of the extendable pipe 606, and the fan cover 607 at the end of the extendable pipe 606 is moved below the air inlet at the lower end of the shell 1. At this time, under the working pressure of the fan cylinder 3, negative pressure is generated in the extendable pipe 606, the dust collecting box 604, the hose 605 and the negative pressure pipe 601. The blockage on the drain hole is sucked into the dust collecting box 604 by the negative pressure pipe 601. Then the controller 7 controls the negative pressure pipe 601 and the extendable pipe 606 to reset, at this time the unblocking of the drain hole is completed, and the drain function is restored.

[0038] Through the unblocking mechanism 6, the rapid unblocking effect of actively using the negative pressure to extract the blockage when the drain hole of the air conditioner indoor unit is blocked is realized, without opening the shell for cleaning.

The bellows 504 is connected between the drainage hole of the drainage groove 501 and the drainage pipe on the shell 1, and the expansion of the bellows 504 can ensure the stable connection between the drainage hole of the drainage groove 501 and the drainage pipe on the shell 1 when the drainage groove 501 rotates.

[0040] Under normal circumstances, the condensed water is collected in the drainage groove 501 and discharged through the drainage hole. When the drainage hole is blocked, with the accumulation of condensed water, one end of the drainage groove 501 will rotate downward to overcome the elastic force of the expansion spring 502 under the action of gravity until it contacts the touch switch 503, and the touch switch 503 sends an electrical signal to the controller 7, and the controller 7 executes the unblocking instruction.

[0041] Through the drainage assembly 5, the self-weight of the condensed water accumulated after the blockage is used to increase the inclination of the drainage groove 501 to trigger the touch switch 503, so as to realize the effect of actively starting the unblocking mechanism 6 to unblock in time when the drainage hole is blocked. The control structure is simple and efficient, and the timeliness of unblocking is guaranteed.

[0042] The horizontal driving mechanism 608 comprises a lead screw 6081 and a motor 6082. The lead screw 6081 is horizontally installed on the lower end surface of the shell 1 above the expansion tube 606 through a suspension bracket, and one end of the expansion tube 606 is threadedly connected with the lead screw 6081 through a mounting connector. The motor 6082 is installed on the lower end surface inside the shell 1, and a gear set 6083 is connected between the motor 6082 and the lead screw 6081, the gear set 6083 is composed of a plurality of gears for connecting the output end of the motor 6082 with the end of the lead screw 6081 to ensure the power output of the motor 6082 to the lead screw 6081.

[0043] When it is necessary to drive the expansion tube 606 to move horizontally, the motor 6082 is started, and the lead screw 6081 is rotated by the motor 6082, and the moving direction of the expansion tube 606 can be changed by changing the rotating direction of the motor 6082.
