Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning water pans, in particular to a central air-conditioning water pan device for efficiently collecting water. Background Art

[0002] The central air conditioning water pan device, commonly known as the water pan or water collection pan, is an important component in the central air conditioning system. Its main function is to collect and discharge the condensed water generated during the operation of the system. When the central air conditioner is running in cooling mode, the surface temperature of the evaporator of the indoor unit is lower than the dew point temperature of the indoor air, and the moisture in the air will condense into water droplets on the evaporator. These condensed water needs to be effectively collected to prevent dripping or causing humidity problems in the environment around the equipment.

[0003] The water tray is usually located at the bottom of the indoor unit and is designed with an appropriate inclination angle and drain outlet to ensure that the condensed water can flow smoothly to the drain outlet and be discharged to the outside or the designated drainage system through the connected drain pipe.

[0004] However, during use, the current water collection pan is prone to form a warm and humid environment due to frequent contact with water, which is an ideal condition for the growth of mold and algae. In addition, during the operation of the air conditioner, minerals in the water may be deposited on the inner wall of the pipe to form scale, providing attachment points for microorganisms, promoting the growth of mold and algae. Over time, it will cause the drain pipe and external hose of the water collection pan to be blocked, which will prevent the condensed water from being discharged smoothly, causing the water level in the water collection pan to rise until it overflows, which is very inconvenient.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] See also Figure 1-Figure 3 A central air-conditioning water pan device with high efficiency in water collection comprises a water pan body 1 and a water outlet pipe 2 installed on one side of the water pan body 1. A collecting chamber 101 is provided on the upper surface of the water pan body 1, and the collecting chamber 101 is inclined toward one end of the water outlet pipe 2. A movable plate 4 is fixedly connected to the side of the collecting chamber 101 close to the water outlet pipe 2. A slide groove 401 is penetrated through the upper surface of the movable plate 4. A movable mechanism is connected to the outer wall of the water pan body 1 close to one end of the water outlet pipe 2. The output end of the movable mechanism penetrates the water pan body 1 and the slide groove 401, and is connected to a supporting assembly. A water spraying mechanism is connected to the bottom surface of the side of the collecting chamber 101 close to the water outlet pipe 2. A universal pipe 7 is connected to the output end of the water spraying mechanism. A nozzle 9 is connected to the other end of the universal pipe 7. The other end of the nozzle 9 penetrates the supporting assembly and is aligned with the water outlet pipe 2. A stop water level sensor 12 is connected to the outer wall of the supporting assembly, and an opening water level sensor 13 is connected to the inner wall of the movable plate 4.

[0020] like Figures 1 to 3 As shown, when the central air-conditioning water pan device with high efficiency in water collection in the utility model receives water droplets under the central air-conditioning, if the inside of the water pan body 1 and the water outlet pipe 2 are blocked due to the presence of mold, algae and scale, the accumulated water in the collecting chamber 101 cannot be discharged, so the water level in the collecting chamber 101 will slowly rise. When the water level rises to contact with the opening water level sensor 13, the opening water level sensor 13 will quickly transmit an electrical signal to the internal processor of the central air-conditioning, and then start the moving mechanism and the water spraying mechanism through the internal controller of the central air-conditioning. After the moving mechanism is started, the supporting assembly will be carried to the water outlet pipe 2. , and during the movement, the nozzle 9 under the supporting assembly is inserted into the water outlet pipe 2. After the water spraying mechanism is started, the accumulated water in the collecting chamber 101 is drawn in from the input end and transported to the universal tube 7 from the output end, and then the outlet pipe 2 is flushed through the nozzle 9. At the same time, the accumulated water in the collecting chamber 101 can be discharged to the outside more quickly. When the accumulated water drops to the position where the water level sensor 12 stops, the electrical signal is also transmitted to the external processor, and then the moving mechanism and the water spraying mechanism are closed through the controller. At this time, the accumulated water in the collecting chamber 101 can be discharged to the outside from the water outlet pipe 2 by itself.

[0021] Special mention should be made here:

[0022] The central air conditioner internal processor and the central air conditioner internal controller are currently available technologies, so they are not described in detail.

[0023] The stop water level sensor 12 and the start water level sensor 13 are both existing common water level sensors, and the different names are only for the convenience of distinguishing functions.

[0024] The water spray mechanism may also be always turned on, but considering that the water outlet pipe 2 will not be always in a blocked state and it can also be more energy-efficient, it can be turned on and off by two water level sensors.

[0025] The nozzle 9 is inserted into the water outlet pipe 2 by a moving mechanism. This is because if the nozzle 9 directly sprays water outward, the sprayed water may not completely enter the water outlet pipe 2, thereby reducing efficiency.

[0026] The stop water level sensor 12 is located above the water spraying mechanism, which can prevent the water level from dropping too low and causing damage to the water spraying mechanism; and the start water level sensor 13 can be located below the opening above the collecting chamber 101, so that the moving mechanism and the water spraying mechanism can be started before the accumulated water overflows from the collecting chamber 101.

[0027] The universal tube 7 is a hose, which has certain expansion and contraction and bending functions.

[0028] Please refer to Figure 2and Figure 3 The moving mechanism includes a motor 3 and a threaded rod 14. The outer wall of the motor 3 is fixedly connected to the outer wall of the water receiving tray body 1. The output shaft of the motor 3 is fixedly connected to one end of the threaded rod 14. The other end of the threaded rod 14 penetrates the water receiving tray body 1, the supporting assembly and the slide groove 401, and is rotatably connected to the inner wall of the moving plate 4.

[0029] More specifically, when the nozzle 9 needs to be inserted into the water outlet pipe 2, the internal controller turns on the switch of the motor 3. After the motor 3 is started, the output shaft can drive the threaded rod 14 to rotate, thereby driving the support assembly located in the slide groove 401 to move.

[0030] Please refer to Figure 2 and Figure 3 The supporting assembly includes a slider 11 and a supporting plate 10. The slider 11 is sleeved and threadedly connected to the outer wall of the threaded rod 14. The outer wall of the slider 11 is slidably connected to the inner wall of the slide groove 401. The bottom surface of the slider 11 is connected to the upper surface of the supporting plate 10. The lower end of the supporting plate 10 is sleeved and fixedly connected to the outer wall of the nozzle 9. The stop water level sensor 12 is fixedly connected to the outer wall of the slider 11.

[0031] More specifically, when the threaded rod 14 rotates, the slider 11 threadedly connected to the surface of the threaded rod 14 will move in the slide groove 401, thereby driving the support plate 10 and the nozzle 9 located at the lower end of the support plate 10 to move horizontally, so that the nozzle 9 can be inserted into the water outlet pipe 2.

[0032] Please refer to Figure 2 and Figure 3 The water spraying mechanism includes a base 6 and a small pump 5. The bottom surface of the base 6 is fixedly connected to the inner wall of the collecting chamber 101, the upper surface of the base 6 is fixedly connected to the outer wall of the small pump 5, and the output end of the small pump 5 is connected to the end of the universal tube 7 away from the nozzle 9.

[0033] More specifically, when it is necessary to flush the inside of the water outlet pipe 2, the internal controller starts the small pump 5. After the small pump 5 is started, the input end draws the accumulated water from the collection chamber 101, and then discharges it from the output end into the universal tube 7, and then sprays it out through the front end of the nozzle 9 at the other end of the universal tube 7, so that the inside of the water outlet pipe 2 can be flushed.

[0034] Please refer to Figure 2 and Figure 3 The universal tube 7 is threadedly connected to the nozzle 9 and the output end of the small pump 5.

[0035] More specifically, it is arranged as a threaded connection, which can be convenient during installation and removal.

[0036] Please refer to Figure 2 and Figure 3A sealing plug 8 is sleeved and fixedly connected to the outer wall of the nozzle 9. The outer wall diameter of the sealing plug 8 is the same as the inner wall diameter of the water outlet pipe 2, and the outer wall of the sealing plug 8 is slidably connected to the inner wall of the water outlet pipe 2.

[0037] More specifically, by providing the sealing plug 8, firstly, when the nozzle 9 flushes the inside of the water outlet pipe 2, no water will flow back into the collecting chamber 101 again; secondly, when the sealing plug 8 is inserted into the inside of the water receiving tray body 1 and the water outlet pipe 2, the inner wall can also be scraped to further improve the flushing efficiency and avoid the situation where mold, algae or scale still exists behind the nozzle 9.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
