Description

Technical Field

[0001] This invention relates to the field of air handling equipment technology, and more specifically, to a water tray assembly and an air conditioning unit. Background Technology

[0002] During the cooling process of an air conditioning unit, the surface temperature of some components may be lower than the dew point temperature of the outdoor fresh air (or mixed return air). When the outdoor air quality is poor, the air carries some dust and particulate matter, which, upon entering the unit, encounters components and some pipe surfaces with temperatures lower than their dew point, condensing into dirty condensate that flows into the drip tray.

[0003] The drip tray has drain holes. Dirt and other debris will move and accumulate in the drain holes under the influence of water flow, clogging the drain holes and preventing condensate from being discharged reliably. Furthermore, dirt remaining in the drip tray will cause pollution and odor to related structures. In the existing technology, in order to remove dirt from the drip tray, the entire components of the drip tray need to be removed from the air conditioner and cleaned manually, which is time-consuming and labor-intensive, seriously affecting the user experience and increasing additional maintenance costs. Summary of the Invention

[0004] This invention discloses a water tray assembly and an air conditioning unit, which solves the problem of inconvenient cleaning of dirt inside the water tray in the prior art.

[0005] This invention discloses a water receiving tray assembly, comprising:

[0006] A water receiving tray, wherein a drainage trough is provided on the water receiving tray;

[0007] A filter structure is movably disposed at the drainage trough.

[0008] The filter structure includes a filter screen, and a drain outlet is provided on the bottom surface of the drainage trough. The filter screen is located between the opening of the drainage trough and the drain outlet.

[0009] The cross-section of the drainage trough is trapezoidal, and the relationship between the width a of the opening of the drainage trough, the width b of the bottom surface of the drainage trough, and the width c of the filter screen is a > c > b.

[0010] The filter structure also includes a side plate, which is disposed on the filter screen and fits snugly against the side wall of the drainage trough.

[0011] The side plate and the filter screen together form a sludge collection trough, and the opening of the sludge collection trough is connected to the opening of the drainage trough.

[0012] Both the drainage trough and the filter structure are elongated, and the filter structure can slide along the length of the drainage trough.

[0013] The drainage channel has a first end face, and a mounting hole is provided on the first end face. The filter structure slides into or out of the drainage channel through the mounting hole.

[0014] The water receiving tray assembly also includes a scraper, which is detachably disposed at the mounting hole and abuts against the side of the filter screen facing the opening of the drain channel.

[0015] The scraper is provided with an observation window; or, the scraper is made of a transparent material.

[0016] The filter structure is equipped with a pull ring.

[0017] The water receiving tray includes a base plate on which the drainage groove is formed, and the filter screen structure is movably disposed on the base plate.

[0018] The bottom plate has an arc-shaped cross-section, and the drainage trough is located at the lowest point of the arc.

[0019] Another aspect of the present invention provides an air conditioning unit including the above-described water tray assembly.

[0020] The water tray assembly and air conditioning unit of the present invention have a movable filter structure installed at the drain groove of the water tray. The water flow in the water tray carries the dirt to the filter structure for collection, avoiding the situation where dirty condensate water stays in certain parts of the water tray for a long time and causes dirt accumulation. When cleaning the water tray, the dirt can be collected and transferred out of the water tray by moving the filter structure, so that the water tray does not need to be disassembled, saving time and effort, effectively improving the user experience and saving maintenance costs.

[0027] The present invention will be further described below with reference to embodiments, but is not limited to the contents of the specification.

[0028] like Figures 1 to 5 As shown, this invention discloses a water receiving tray assembly, including: a water receiving tray 1, on which a drainage groove 11 is provided; and a filter structure, which is movably disposed at the drainage groove 11. The movable filter structure at the drainage groove 11 of the water receiving tray 1 utilizes the water flow within the water receiving tray 1 and its arc-shaped bottom surface to carry dirt to the filter structure for collection. This prevents dirt and condensate from accumulating in certain parts of the water receiving tray 1 for extended periods. When cleaning the water receiving tray 1, the movement of the filter structure easily transfers the dirt out of the water receiving tray 1, eliminating the need for complete disassembly and reassembly of the entire water receiving tray 1. This saves time and effort, effectively improves user experience, and reduces maintenance costs.

[0029] The filter structure moves by sliding, meaning it is installed or removed by pulling it out.

[0030] The filter structure includes a filter screen 21, and a drain outlet 12 is provided on the bottom surface of the drainage trough 11. The filter screen 21 is located between the opening of the drainage trough 11 and the drain outlet 12. The water in the water receiving tray 1 can carry dirt to the opening of the drainage trough 11 and flow to the filter screen 21 under the action of gravity. The mixture of water and dirt flowing into the dirt accumulation tank is separated by the filtration action of the filter screen 21. The condensate can continue to flow through the filter screen 21 and is finally discharged from the drain outlet 12. The dirt is collected by the filter screen 21, and the dirt can be directly removed when the filter structure is moved.

[0031] The drainage channel 11 has a trapezoidal cross-section. The width a at the opening of the drainage channel 11, the width b at the bottom of the drainage channel 11, and the width c of the filter screen 21 are related as a > c > b. The filter screen 21 will be held in place at the middle of the height direction of the drainage channel 11 by the limiting effect of the width, thereby creating a gap between the filter screen 21 and the drain outlet 12, which facilitates drainage and also facilitates the fixation of the filter structure.

[0032] The filter structure also includes a side plate 22, which is disposed on the filter screen 21 and fits snugly against the side wall of the drainage trough 11. The side plate 22 increases the fit between the filter screen 21 and the side wall of the drainage trough 11, and this fit prevents water and dirt from leaking between them, ensuring the reliability of the filter structure.

[0033] The side plate 22 and the filter screen 21 together form a dirt accumulation tank. The opening of the dirt accumulation tank is connected to the opening of the drainage tank 11, so that dirt can be accumulated in the dirt accumulation tank. When the filter screen structure is moved, the dirt can reliably leave the water receiving tray 1 with the filter screen structure, thereby ensuring the cleaning effect of the water receiving tray 1.

[0034] Both the drainage trough 11 and the filter structure are elongated, and the filter structure can slide along the length of the drainage trough 11. The drainage trough 11 of a certain length is formed on the water receiving tray 1 to increase the drainage effect of the water receiving tray 1, while also providing space for the movement of the filter structure, ensuring reliable movement of the filter structure.

[0035] The drainage channel 11 has a first end face, and a mounting hole is provided on the first end face. The filter structure slides into or out of the drainage channel 11 through the mounting hole.

[0036] The water receiving tray assembly also includes a scraper 13, which is detachably disposed at the mounting hole and abuts against the side of the filter screen facing the opening of the drainage channel. Along the moving direction of the filter screen structure, the filter screen structure has opposing front and rear faces. When the filter screen structure is fixed on the water receiving tray 1, the front face is located at the first end face, effectively sealing the mounting hole and ensuring the water receiving effect of the water receiving tray 1. As the filter screen structure moves on the water receiving tray 1, the rear face gradually approaches the scraper 13. At this time, the scraper 13 scrapes away the dirt inside the filter screen structure. Under the squeezing action of the scraper 13 and the rear face, the dirt further releases water. Then, the scraper 13 is removed, and the filter screen structure is pulled out. The user can directly clean the dirt on the rear side, further improving the cleaning effect.

[0037] The scraper 13 is equipped with an observation window. Users can directly observe the amount of dirt in the dirt accumulation tank through the observation window, and choose to clean it when there is too much dirt.

[0038] Preferably, the scraper 13 is made of a transparent material.

[0039] The filter structure is equipped with a pull ring 23. Users can move the filter structure using the pull ring 23 for convenient operation.

[0040] The water receiving tray 1 includes a base plate 14, on which the drainage groove 11 is formed, and the filter screen structure is movably disposed on the base plate 14.

[0041] The base plate 14 has an arc-shaped cross-section, and the drainage channel 11 is located at the lowest point of the arc. The opening of the drainage channel 11 is tangentially positioned at the connection point with the base plate 14. The arc shape allows water and dirt to flow towards the drainage channel 11 as much as possible.

[0042] Another aspect of the present invention provides an air conditioning unit including the above-described water tray assembly.

[0043] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all embodiments here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
