Abstract
Description
Technical Field
[0001] The invention relates to the technical field of air-conditioning condensed water discharge, in particular to a condensed water discharge device for an indoor unit of an air-conditioning unit. Background Art
[0002] The compressor compresses the gaseous Freon into high-temperature, high-pressure gaseous Freon, which is then sent to the condenser (outdoor unit) where it dissipates heat and becomes liquid Freon at room temperature and high pressure. The liquid Freon then flows through the capillary tube into the evaporator (indoor unit). The sudden increase in volume and decrease in pressure cause the liquid Freon to vaporize, turning into a low-temperature gaseous Freon. This absorbs a significant amount of heat, cooling the evaporator. The indoor unit's fan blows the indoor air through the evaporator, resulting in cool air. Water vapor in the air condenses into water droplets upon encountering the cold evaporator, which then flows out through the pipes.
[0003] In some poor air environments, such as kitchens, the oil smoke and dust in the air are difficult to be filtered by the filter of the air conditioner's indoor unit, causing the oil smoke and dust in the air to come into contact with the evaporator and enter the drain pipe with the condensed water to form dirt, causing the condensed water drain pipe to be frequently blocked. Users generally choose to clear the drain pipe only when condensed water overflows from the air conditioner outlet. In this case, the dirt in the drain pipe is relatively stubborn, making it difficult to clean the drain pipe.
[0004] In view of this, in order to overcome the above technical problems, the present invention proposes a condensed water discharge device for an indoor unit of an air conditioner, which solves the above technical problems. Summary of the Invention

DETAILED DESCRIPTION
[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0021] like Figures 1 to 5 As shown, the present invention includes the following embodiments: Example 1: A condensate discharge device for an indoor unit of an air conditioner comprises a shell 1 and a circulation groove 11 inside the shell 1; a first joint 2 communicating with the circulation groove 11 is provided on the top of the shell 1; a second joint 3 communicating with the circulation groove 11 is provided on the bottom of the shell 1; a dredging groove 12 is provided on the wall of the circulation groove 11; a dredging plate 4 is connected to the dredging groove 12 in a sliding seal; the dredging plate 4 is fixedly connected to a connecting strip 41 on the side facing away from the circulation groove 11; one end of the connecting strip 41 extends through the shell 1 to the outside; the connecting strip 41 is movably connected to the shell 1; the end of the connecting strip 41 away from the dredging plate 4 is fixedly connected to a holding block 42; the notch of the dredging groove 12 is fixedly connected to a limit block 13; the shell 1 is made of transparent material; the discharge device is connected in series to the condensate drain pipe.
[0022] In this embodiment, the outer walls of the first joint 2 and the second joint 3 are provided with external threads; the outer wall of the first joint 2 is sleeved with a first internal threaded sleeve 21; the outer wall of the second joint 3 is sleeved with a second internal threaded sleeve 31; the outer diameters of the first joint 2 and the second joint 3 are adapted to the inner diameter of the drain pipe; the shell 1 is made of transparent material.
[0023] When working, after the air conditioner indoor unit is installed in place, the shell body 1 is kept in a vertical state so that the first joint 2 is located above the second joint 3, and then the tail end of the drain pipe (not shown in the figure) connected to the air conditioner indoor unit is sleeved on the outer wall of the first joint 2, and then the first internal threaded sleeve 21 is controlled to move away from the shell body 1. The first internal threaded sleeve 21 will be sleeved on the outer wall of the drain pipe. The internal thread of the first internal threaded sleeve 21 cooperates with the external thread of the first joint 2. Therefore, in the process of twisting the first internal threaded sleeve 21, the end of the drain pipe is tightened between the first joint 2 and the first internal threaded sleeve 21, completing the connection between the end of the drain pipe and the first joint 2. Then the staff will sleeve one end of an extension pipe (not shown in the figure) of the same material and shape as the drain pipe on the outer wall of the second joint 3, and use the second internal threaded sleeve 31 to twist so that one end of the extension pipe is connected to the second joint 3. In order to make the first joint 2 and the drain pipe, and the second joint 3 and the extension pipe connected more tightly, raw tape can be wrapped around the outer walls of the first joint 2 and the second joint 3 to improve the sealing; After completing the connection of the first joint 2 and the second joint 3, the air conditioner can be put into use. During the operation of the air conditioner indoor unit, the indoor air will pass through the filter on the upper part of the air conditioner indoor unit and enter the interior of the air conditioner indoor unit. The indoor air will come into contact with the evaporator. Since the air environment of the indoor air in this embodiment is poor, some impurities such as oil smoke or dust will come into contact with the evaporator along with the air. The impurities will condense with the condensed water and drip into the water receiving pan. The water receiving pan is connected to the drain pipe, and the sewage in the water receiving pan will flow along the drain pipe. The sewage will flow into the first joint 2 along the drain pipe and flow into the flow along the first joint 2. The sewage in the flow groove 11 flows into the extension pipe along the second joint 3 and is finally discharged along the extension pipe. Since the shell 1 is made of transparent material, the user can observe the flow of sewage in the flow groove 11 and the flow color through the shell 1. During the cooling process, it is observed that the dripping of sewage in the flow groove 11 is significantly higher than that at the same temperature, and the color of the sewage is darker, indicating that there is a blockage at the position where the drain pipe is connected to the water receiving tray, or at one or more places inside the drain pipe and the extension pipe. Then, when the user holds the grip block 42, the user can hold the grip block 42 to remove the sewage. Drive the connecting strip 41 and the dredging plate 4 to move, and the dredging plate 4 divides the internal space of the dredging groove 12 into a stripless cavity and a striped cavity. The striped cavity is located on the side of the dredging plate 4 away from the flow groove 11, the striped cavity is connected to the external gas, and the stripless cavity is connected to the flow groove 11. In this way, the holding block 42 controls the dredging plate 4 to move away from the flow groove 11 in the dredging groove 12. The space of the stripless cavity expands and the space of the striped cavity decreases. In the process of the expansion of the stripless cavity to form a negative pressure, the extension tube can be artificially pinched continuously without pinching the drainage pipe, so that the extension tube is temporarily closed and the drainage pipe is opened, so that the fluid or dirt in the drainage pan can be discharged. Under the action of negative pressure, the fluid flows along the drain pipe into the circulation groove 11, and then the dredging plate 4 is controlled to move close to the circulation groove 11, so that the space without the strip cavity becomes smaller and the space with the strip cavity becomes larger. In the process of the space without the strip cavity becoming smaller, the drain pipe can be manually squeezed and the extension pipe is loosened, so that the drain pipe is temporarily closed and the extension pipe is opened. The fluid in the circulation groove 11 will be discharged along the extension pipe. The above action is repeated again until the staff feels that the resistance of the dredging plate 4 to move back and forth is small, indicating that the drain pipe and the extension pipe are dredged. Finally, after loosening the drain pipe and the extension pipe, the air conditioner indoor unit is enabled to operate again. In this embodiment, the surface of the dredging plate 4 in contact with the inner wall of the dredging groove 12 is provided with a sealing groove (not numbered in the figure), and an annular sealing strip (not numbered in the figure) is provided in the sealing groove to ensure the sealing of the dredging plate 4 after sliding back and forth in the dredging groove 12; This embodiment can control the movement of the dredging plate 4 in the dredging groove 12 according to the drainage demand of the condensed water, thereby changing the fluid pressure in the circulation groove 11, so that the drain pipe and the extension pipe can be dredged and drained with the assistance of the discharge device. Compared with the existing dredging tools that dredge the drain pipe separately, the present invention has the characteristics of high efficiency, timeliness and convenience, so that the condensed water can be smoothly discharged under harsh surrounding environments. In addition, the present invention dredges the drain pipe and the extension pipe before they are completely blocked. Compared with the existing dredging timing, the dirt in the drain pipe and the extension pipe will not be too stubborn, the dredging difficulty is low, and the dredging efficiency is high.
[0024] Example 2: The shell 1 is laterally penetrated by an upper slide groove 14 and a lower slide groove 15; the upper slide groove 14 is arranged near the top of the shell 1 and is connected to the interior of the first joint 2; the upper slide groove 14 is slidingly and sealedly connected to the upper slide bar 5; the upper slide bar 5 is penetrated by a one-way air inlet hole 51 and a first through hole 52; the one-way air inlet hole 51 and the first through hole 52 are spaced apart; the one-way air inlet hole 51 and the first through hole 52 are connected to the interior of the first joint 2 after the upper slide bar 5 slides; the lower slide groove 15 is slidingly and sealedly connected to the lower slide bar 6; the lower slide bar 6 is penetrated by a one-way air outlet hole 61 and a second through hole 62; the one-way air outlet hole 61 and the second through hole 62 are spaced apart; the one-way air outlet hole 61 and the second through hole 62 are connected to the interior of the second joint 3 after the lower slide bar 6 slides.
[0025] In this embodiment, the openings of the one-way air inlet 51 and the first through hole 52 are both provided with an upper positioning ring 53; the outer diameter of the upper positioning ring 53 is adapted to the inner diameter of the first joint 2; the openings of the one-way air outlet 61 and the second through hole 62 are both provided with a lower positioning ring 63; the outer diameter of the lower positioning ring 63 is adapted to the inner diameter of the second joint 3; the upper positioning ring 53 and the lower positioning ring 63 are both made of elastic material.
[0026] During operation, when the user observes that the flow rate or color of the condensed water droplets in the shell 1 is abnormal, the user starts to control the discharge device to work, specifically, first push the upper slide bar 5, which will slide along the upper slide groove 14 under the push. During the sliding process of the upper slide bar 5, the one-way air inlet hole 51 and the first through hole 52 will move accordingly, so that the first through hole 52 originally connected to the inside of the first joint 2 is staggered, and the upper positioning ring 53 on the inner side of the orifice of the first through hole 52 is compressed. At the same time, the one-way air inlet hole 51 is aligned with and connected to the inside of the first joint 2 after the upper slide bar 5 moves, and the upper positioning ring 53 on the inner side of the orifice of the one-way air inlet hole 51 is compressed. After being aligned with the inside of the first joint 2, the one-way air inlet 51 is positioned; then the staff will push the sliding strip 6 to slide along the sliding groove 15, and the second through hole 62 will be offset from the inside of the second joint 3 after the sliding of the sliding strip 6, and the lower positioning ring 63 on the inner side of the second through hole 62 orifice will be compressed as the second through hole 62 is offset from the inside of the second joint 3, and the one-way air outlet 61 will be aligned with the inside of the second joint 3 and connected after the sliding of the sliding strip 6, and the lower positioning ring 63 on the inner side of the orifice of the one-way air outlet 61 will be elastically reset and stuck into the inside of the second joint 3, thereby positioning the one-way air outlet 61; then the staff will hold the gripping block In the case of 42, the dredging plate 4 is controlled to move back and forth in the dredging groove 12, so that the space in the stripless cavity circulates back and forth, so that the fluid or dirt in the drain pipe passes through the first joint 2 and the one-way air inlet 51 into the circulation groove 11, and the fluid in the circulation groove 11 will be discharged into the extension pipe along the one-way air outlet 61 and the second joint 3, thereby achieving auxiliary drainage of the drain pipe and the extension pipe and timely dredging; after completing the drainage and dredging, the staff controls the upper slide bar 5 and the lower slide bar 6 to slide in reverse, and the one-way air inlet 51 is staggered with the inside of the first joint 2 after the upper slide bar 5 is pushed, and the one-way air inlet 51 is holed. The upper positioning ring 53 on the inner side of the opening is compressed under pressure, and the first through hole 52 is aligned with the inside of the first joint 2 and communicated with after the upper slide bar 5 is pushed. The upper positioning ring 53 on the inner side of the opening of the first through hole 52 is restored and snapped into the inside of the second joint 3, thereby achieving the positioning of the first through hole 52; similarly, the one-way air outlet 61 is staggered with the second joint 3 after the sliding bar 6 slides, and the second through hole 62 is aligned with the second joint 3 and communicated with after the sliding bar 6 slides. In this way, during normal circulation of the drain pipe and the extension pipe, there will be no resistance from the one-way air inlet 51 and the one-way air outlet 61, so that the condensed water in the drain pipe and the extension pipe can flow out smoothly; This embodiment uses the one-way air inlet 51 and the one-way air outlet 61 to avoid the need to alternately pinch the drain pipe and the extension pipe during the auxiliary drainage and dredging process, thereby avoiding the drain pipe and the extension pipe from being compressed and deformed, which may affect the subsequent flow of condensed water, thereby ensuring the stability of condensed water discharge.
[0027] Example 3: The lower wall of the circulation groove 11 is lower than the lower wall of the dredging groove 12 in the vertical direction; an inclined slope 16 is provided at the corner of the lower wall of the circulation groove 11; the second joint 3 is located directly below the inclined slope 16; a slope hole 17 connected to the interior of the second joint 3 is provided at the upper position of the inclined slope 16; a discharge groove 18 is provided at the lower position of the lateral inner wall of the circulation groove 11; the sliding seal in the discharge groove 18 cooperates with the discharge box 7; the discharge box 7 contacts the inclined slope 16 after entering the circulation groove 11; the upper port of the discharge box 7 is flush with the slope hole 17 in the vertical direction; the first joint 2 is located directly above the discharge box 7 and is staggered with the second joint 3.
[0028] In this embodiment, a locking groove 181 is provided on the upper groove wall of the discharge trough 18; a rotating groove 71 is provided on the upper surface of the discharge box 7 at a position corresponding to the locking groove 181; the rotating groove 71 penetrates the outer side of the discharge box 7 and is rotatably connected to a connecting rod 72; the connecting rod 72 is located on the outer side of the discharge box 7 and is eccentrically fixed to the first rotating block 73; the connecting rod 72 is located inside the rotating groove 71 and is eccentrically fixed to the second rotating block 74 at one end; the gravity of the first rotating block 73 is greater than the gravity of the second rotating block 74; the second rotating block 74 is stuck in the locking groove 181 under the action of the gravity of the first rotating block 73.
[0029] During operation, after the condensed water enters the circulation groove 11 along the drainage pipe and the first joint 2, the condensed water and dirt will fall into the discharge box 7, and the dirt will settle at the inner bottom of the discharge box 7. The condensed water at the upper port of the discharge box 7 is relatively clear, and the condensed water at the upper port of the discharge box 7 will overflow along the upper port and enter the slope hole 17. The condensed water will enter the extension pipe along the slope hole 17 and the second joint 3 to be discharged; in the process of using the discharge device to assist in drainage and dredging, the dirt in the drain pipe flows into the first joint 2 with the condensed water and falls into the flow The discharge box 7 is at the bottom of the through groove 11, and the condensed water overflowing from the discharge box 7 and the gas in the circulation groove 11 will enter the slope hole 17 and the second joint 3 for discharge. The discharge box 7 collects the dirt to prevent the dirt from entering the extension pipe and being blocked again. During the dirt collection process of the discharge box 7, since the gravity of the first rotating block 73 is greater than the gravity of the second rotating block 74, the first rotating block 73 is positioned lower than the second rotating block 74, and the second rotating block 74 is locked in the locking groove 181, thereby locking the discharge box 7, so that the discharge box 7 can stably collect dirt; When the hopper 71 is in the unlocking position, the locking cam 76 will be turned to the unlocking position, and the lock cam 78 will be turned to the unlocking position, and the lock cam 76 will be turned to the unlocking position, and the lock cam 76 will be turned to the unlocking position, and the lock cam 76 will be turned to the unlocking position, and the lock cam 76 will be turned to the unlocking position, and the lock cam 76 will be turned to the unlocking position, and the lock cam 76 will be turned to the unlocking position, and the lock cam 76 will be turned to the unlocking position, and the lock cam 76 will be turned to the unlocking position, and the lock cam 76 will be turned to the unlocking position, and the lock cam 76 will be turned to the unlocking position

Then, the shell 1 drives the L-shaped block 19 to be inserted into the L-shaped groove 82 to realize the connection between the shell 1 and the mounting plate 8. During the subsequent observation and replacement process, the shell 1 can be directly controlled to slide upward to realize the separation of the shell 1 and the mounting plate 8, thereby facilitating the staff to replace and install the discharge device to meet the use requirements.
[0032] Example 5: The dredging plate 4 and the limiting block 13 are embedded in the magnetic block 43 at corresponding positions; the magnetic block 43 and the limiting block 13 are both made of magnetic materials and can attract each other.
[0033] During operation, when the dredging plate 4 is not activated, the magnetic attraction between the magnetic block 43 and the limit block 13 causes the dredging plate 4 to be located close to the limit block 13, so that the holding block 42 is driven by the dredging plate 4 to be located close to the shell 1, thereby reducing the space occupied by the discharge device in the surrounding area during normal use, so that when the holding block 42 is close to the shell 1, it is not easy for surrounding objects to collide with the discharge device.
