Description

Technical Field

[0001] The present disclosure relates to the technical field of compressors, and in particular to a water receiving pan assembly, an air conditioner indoor unit and an air conditioner. Background Art

[0002] In most closed indoor units, if the indoor fan is in front of the heat exchanger, that is, the fan extracts indoor air and discharges it to the heat exchanger, the air pressure in the area where the heat exchanger is located is greater than the indoor ambient pressure, which is a positive pressure; if the indoor fan is behind the heat exchanger, that is, the fan extracts air in the air duct after the heat exchanger and discharges it to the indoor environment, the air pressure in the area where the heat exchanger is located is less than the indoor ambient pressure, which is a negative pressure. However, if the indoor fan is set in front of the heat exchanger, the problem of condensed water being blown into the room will occur. In order to avoid the problem of blowing water, the indoor fan is usually designed after the heat exchanger. At this time, the air duct in the indoor heat exchanger area is at a negative pressure relative to the indoor ambient pressure. However, in the case where a negative pressure is formed between the indoor unit chamber and the external atmospheric pressure, the water in the water receiving pan cannot be discharged. A commonly used method is to use a water trap on the outside, and utilize the height difference between the two water columns in the water trap to ensure that the inside of the water receiving pan is sealed from the outside and that the water in the water receiving pan is discharged through the water trap. However, the structure of this water trap has the problem that the water cannot be discharged outward from the water receiving pan after the water evaporates in the water trap, and water needs to be refilled, which occupies a large external space and is not aesthetically pleasing.

[0003] Since the closed indoor unit in the prior art uses a water trap to ensure that the negative pressure condition inside the indoor unit can still discharge condensed water, but there is a technical problem that after the water in the water trap evaporates, the water receiving pan is under negative pressure and the water cannot be discharged outward from the water receiving pan. Therefore, the present invention studies and designs a water receiving pan assembly, an air conditioner indoor unit and an air conditioner.

[0029] like Figure 1-4 As shown, the present disclosure provides a water receiving tray assembly, which includes:

[0030] The water receiving tray 1 and the first partition 2, wherein the first partition 2 is arranged at the upper end of the water receiving tray 1, and at least one first through hole 21 is vertically penetrated on the first partition 2, and water can pass through the first through hole 21 to form a water film and fall onto the water receiving tray 1.

[0031] The present invention uses a first partition plate provided at the upper end of the water receiving tray, especially a first through hole provided on the first partition plate, which runs through the upper and lower parts, so that condensed water first drips onto the first partition plate, enters the first through hole to form a liquid film, and finally reaches the water receiving tray. The liquid film formed at the first through hole can effectively form a sealing effect, effectively reduce the pressure difference effect caused by the negative pressure inside and outside the indoor unit, so that the water under the liquid film can be smoothly discharged from the water receiving tray to the outside; the technical problem that the condensed water on the water receiving tray cannot be discharged due to the negative pressure is effectively solved, and a water trap does not need to be provided, which effectively solves the technical problem that the condensed water in the water trap cannot be discharged after the water evaporates, and the water trap does not need to be refilled with water. The present invention occupies a small space and has a compact structure.

[0032] The method for draining condensed water under negative pressure of the water receiving tray component disclosed in the present invention is as follows: two partitions are installed on the water receiving tray, with a distance of about 5 mm between the partitions, and rows of drainage holes are opened on both partitions. Due to the surface tension of water, after the condensed water gathers on the upper partition, it will form the first water film in the rows of drainage holes, and the excess condensed water will form the second water film between the gap between the upper partition and the lower partition, and the third water film will be formed in the drainage holes of the lower partition. After the water film is formed, the negative pressure on the indoor side of the water surface of the water receiving tray will be significantly reduced, and the condensed water on the water receiving tray can be drained more easily; in addition, a hole is opened at the bottom of the water receiving tray, and a small recessed bracket is used as a water storage tank, and a drainage pipe is connected. The condensed water on the indoor side flows from the indoor side → upper partition → water film → lower partition → water film → water receiving tray, and after gathering at the bottom of the water receiving tray, it naturally flows out from the low-level drainage holes on both sides.

[0033] In a structure with a water trap, if the water in the water trap has completely evaporated, the newly generated condensed water is not easy to flow into the water trap to form water accumulation, resulting in a large amount of water accumulation in the water receiving tray. However, the water film of the present disclosure is formed at the beginning stage of the condensed water flow path, so as long as there is a small amount of condensed water, the condensed water can be discharged smoothly.

[0034] In some embodiments, a water receiving groove 11 is formed on the water receiving tray 1, and the bottom of the water receiving groove 11 is at a first preset height H1 from the lower end surface of the first partition 2, and the water falling from the first through hole 21 falls into the water receiving groove 11. The present disclosure can accommodate condensed water falling from the first partition by setting the water receiving groove on the water receiving tray, and play a role in effectively storing water.

[0035] In some embodiments, the water receiving tray 1 further comprises a water guide pipe 12, one end of which is connected to the water receiving groove 11 and the other end of which can guide water out. The present disclosure can effectively guide water out of the water receiving groove through the water guide pipe.

[0036] In some embodiments, the upper end surface of the water-containing groove 11 is spaced from the lower end surface of the first partition 2 by a second preset height H2, and the water receiving tray 1 further comprises at least one inclined surface 13, the inclined surface 13 is located below the first partition 2 and above the water-containing groove 11, and the water flowing down from the first through hole 21 of the first partition 2 can be guided into the water-containing groove 11 via the inclined surface 13. The present disclosure can guide the water falling from the first through hole in the first partition through the setting of the inclined surface, so that it can fall into the water-containing groove to complete the water collection function.

[0037] In some embodiments, a first threaded fastener 41 is further included, and the first threaded fastener 41 fixes the first baffle 2 to the water receiving tray 1, and the first threaded fastener 41 defines the second preset height H2 between the upper end surface of the water containing groove 11 and the first baffle 2. The present disclosure can fix the first baffle to the water receiving tray by providing the first threaded fastener, and define the second preset height between the first baffle and the water containing groove by the first threaded fastener, so as to ensure that there is a certain height space between the two, which can be effectively used for storing and draining water.

[0038] In some embodiments, there are multiple first through holes 21, and the multiple first through holes 21 are arranged in multiple rows and columns on the first partition plate 2. This is a preferred structural form of the first through holes disclosed in the present invention. Multiple liquid films can be formed on the first partition plate through the multiple first through holes, which effectively improves the sealing effect. In particular, the multiple rows and columns of first through holes can increase the flow area while effectively improving the sealing effect, thereby enhancing the effect of smooth discharge of condensed water.

[0039] In some embodiments, a second partition plate 3 is further included, the second partition plate 3 is located above the first partition plate 2, and at least one second through hole 31 is vertically penetrated on the second partition plate 3, and water can pass through the second through hole 31 to form a water film and further fall onto the first partition plate 2. The present disclosure adopts a second partition plate further disposed above the first partition plate, and the second through hole that penetrates up and down on the second partition plate can further form a liquid film structure on the second partition plate, which can further enhance the sealing effect, further improve the effect of condensed water being discharged outward, and further solve the problem that condensed water cannot be discharged due to negative pressure.

[0040] The improvement disclosed in the present invention lies in that a negative pressure drainage component is added on the basis of a general water receiving tray, and the component realizes negative pressure drainage in the following manner: two partitions are installed on the drainage tray, with a distance of about 5 mm between the partitions, and rows of drainage holes are opened on the two partitions. Due to the existence of surface tension of water, layers of water film will be formed between the holes of the partitions. After the water film is formed, the negative pressure of the indoor water receiving tray will be reduced to prevent the condensed water on the water receiving tray from being unable to be discharged due to negative pressure; in addition, a hole is opened at the bottom of the water receiving tray, a small recessed bracket is used as a water storage tank, and a drainage pipe is connected to drain the condensed water.

[0041] (1) Solve the problem that the existing negative pressure drain pan has difficulty in draining water without using a water trap, and even blows water;

[0042] (2) Solve the problem that when a water trap is set, the unit will not be operated for a long time, and the water in the water trap will evaporate, resulting in difficulty in drainage;

[0043] (3) Solve the problem of drainage difficulties in narrow spaces or other situations where it is not suitable to install a trap;

[0044] (4) Solve the problem that in some cases the unit installation location can be directly drained, and the use of a water trap will damage the overall aesthetics;

[0045] (4) The present disclosure can comprehensively solve various problems of the water receiving tray structure without obvious disadvantages.

[0046] In some embodiments, there are multiple second through holes 31, and the multiple second through holes 31 are arranged in multiple rows and columns on the second partition plate 3. This is a preferred structural form of the second through holes disclosed in the present invention. Multiple liquid films can be formed on the second partition plate through the multiple second through holes, which effectively improves the sealing effect. In particular, the multiple rows and columns of second through holes can increase the flow area while effectively improving the sealing effect, thereby enhancing the effect of smooth discharge of condensed water.

[0047] In some embodiments, the second through hole 31 is staggered with the first through hole 21, that is, the second through hole 31 is not directly opposite to the first through hole 21 (interpreted as: any two through holes that are not directly opposite are staggered). The staggered first through holes and the first through holes can prevent the condensed water from flowing directly out of the first through holes when flowing downward through the second through holes, thereby ensuring the effective duration of the liquid film, improving the sealing performance, and enhancing the effect of smoothly discharging the condensed water.

[0048] In some embodiments, there is a third preset height H3 between the lower end surface of the second partition 3 and the upper end surface of the first partition 2, and a liquid film can also be formed between the lower end surface of the second partition 3 and the upper end surface of the first partition 2. The third preset height H3 formed between the first partition and the second partition can further form a liquid film in this space, further improving the sealing effect, improving the effect of condensed water discharge to the outside, and further solving the problem that condensed water cannot be discharged due to negative pressure.

[0049] In some embodiments, a second threaded fastener 42 is further included, and the second threaded fastener 42 fixes the second partition 3 to the first partition 2, and the second threaded fastener 42 defines the third preset height H3 between the lower end surface of the second partition 3 and the upper end surface of the first partition 2. The second threaded fastener provided in the present disclosure can fix the second partition to the first partition, and the third preset height is defined between the second partition and the first partition by the second threaded fastener, so that a certain height space can be ensured between the two, which can be effectively used to form a liquid film space, improve the sealing performance, and enhance the effect of smoothly discharging condensed water.

[0050] The present disclosure also provides an air-conditioning indoor unit, which includes the water receiving tray assembly described in any of the preceding items.

[0051] The present disclosure also provides an air conditioner, which includes the water receiving tray assembly described in any of the preceding items or includes the aforementioned air conditioner indoor unit.

[0052] The present invention adds a negative pressure drainage component on the basis of a general water receiving tray. The installation method of this component is as follows:

[0053] Install the lower baffle on the water tray, and fix the two with a simple bolt assembly;

[0054] Install the upper partition about 5mm above the lower partition and fix them with a simple bolt assembly;

[0055] The gap between the upper partition and the lower partition can be achieved by a bracket or a welded nut.

[0056] The method for draining condensed water under negative pressure of the water receiving tray component disclosed in the present invention is as follows: two partitions are installed on the water receiving tray, with a distance of about 5 mm between the partitions, and rows of drainage holes are opened on both partitions. Due to the surface tension of water, after the condensed water gathers on the upper partition, it will form the first water film in the rows of drainage holes, and the excess condensed water will form the second water film between the gap between the upper partition and the lower partition, and the third water film will be formed in the drainage holes of the lower partition. After the water film is formed, the negative pressure on the indoor side of the water surface of the water receiving tray will be significantly reduced, and the condensed water on the water receiving tray can be drained more easily; in addition, a hole is opened at the bottom of the water receiving tray, and a small recessed bracket is used as a water storage tank, and a drainage pipe is connected. The condensed water on the indoor side flows from the indoor side → upper partition → water film → lower partition → water film → water receiving tray, and after gathering at the bottom of the water receiving tray, it naturally flows out from the low-level drainage holes on both sides.

[0057] In a structure with a water trap, if the water in the water trap has completely evaporated, the newly generated condensed water is not easy to flow into the water trap to form water accumulation, resulting in a large amount of water accumulation in the water receiving tray. However, the water film of the present disclosure is formed at the beginning stage of the condensed water flow path, so as long as there is a small amount of condensed water, the condensed water can be discharged smoothly.

[0058] The above is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure. The above is only a preferred implementation of the present disclosure. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present disclosure, and these improvements and variations should also be regarded as the protection scope of the present disclosure.
