Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a water tray and an air conditioner. Background Technology

[0002] Air conditioners produce condensation during use, so a drip tray is usually installed inside the air conditioner to collect the condensation.

[0003] In existing air conditioners, square drip trays are limited in application due to structural space constraints. Single and dual cross-flow vertical air conditioners, to ensure the stability of the heat exchanger within the drip tray, often have insufficient clearance between the left and right ends of the heat exchanger and the perimeter of the lower drip tray, leading to insufficient water storage capacity and easy overflow. Therefore, they typically use a double-layer drip tray, with the lower tray catching water overflowing from the upper tray for drainage. For example, a single cross-flow vertical air conditioner uses a combination of a bottom water guide, a large drip tray, and two rubber drip bowls for water collection, while a dual cross-flow vertical air conditioner uses the same combination. Due to limitations in appearance and internal design, double-layer drip trays not only increase height and space requirements but also increase manufacturing costs and reduce production and assembly efficiency. Furthermore, double-layer drip trays are prone to dripping noise, affecting the user experience. Summary of the Invention

[0004] The main objective of this invention is to propose a water collection tray and an air conditioner, aiming to solve the problems of high manufacturing cost and large space occupation of the water collection tray.

[0005] To achieve the above objectives, the water receiving tray proposed in this invention includes a collection trough, two guide troughs, and multiple first support ribs. The two guide troughs are respectively connected to both ends of the collection trough. The multiple first support ribs are disposed in the guide troughs to support the heat exchanger. A water passage gap is formed between the first support ribs and the bottom and / or sidewall of the guide trough. The bottom of the guide trough extends inclined toward the collection trough to guide the water in the guide trough to the collection trough.

[0008] In one embodiment, the first support rib is inclined from one end near one sidewall of the guide channel toward the downstream of the guide channel.

[0009] In one embodiment, the first support rib is arranged in an angular shape.

[0010] In one embodiment, the first support rib is disposed at the bottom of the guide channel, and the first support rib forms the water passage gap with at least one side wall of the guide channel.

[0012] In one embodiment, the upper end of the first support rib is flush with the upper end of the guide groove.

[0013] In one embodiment, the height of the first support rib gradually increases from the upstream to the downstream direction of the guide channel.

[0014] In one embodiment, the guide channel and / or the collecting channel are formed with at least two ramps.

[0042] A typical air conditioner includes several components such as a heat exchanger 30, an air duct assembly, an air outlet frame 20, and a condensate tray 10. The air duct assembly is located in front of the heat exchanger 30, the air outlet frame 20 is located in front of the air duct assembly, and the condensate tray 10 is located below the heat exchanger 30, the air duct assembly, and the air outlet frame 20. During operation, the heat exchanger 30 and the air outlet frame 20 will produce condensate. Therefore, the condensate tray 10, which is usually installed inside the air conditioner, is used to collect this condensate and prevent it from flowing outside the air conditioner or onto other components, causing water damage indoors or affecting the user experience. Please refer to [link / reference]. Figure 1 In existing single and dual cross-flow vertical air conditioners, to ensure the installation stability of the heat exchanger 30, the gap between the left and right ends of the heat exchanger 30 and the periphery of its lower water tray 10 is too small, resulting in insufficient water storage capacity and easy overflow. Typically, a double-layer water tray 10' is used, with the lower layer of the double-layer water tray 10' collecting water from the upper layer for drainage. This increases the vertical space occupied by the air conditioner, increases mold manufacturing costs, and reduces assembly efficiency.

[0043] This invention proposes a novel water receiving tray 10. The water receiving tray 10 utilizes a bottom-guided flow system via a heat exchanger 30 mounted on it. Its single-layer structure design reduces mold manufacturing and assembly costs, improves production efficiency, and allows for miniaturization and compact layout of the entire unit's core components. This effectively reduces the overall height of the unit, minimizes its footprint in the user's room, and enhances aesthetic appeal. Furthermore, the water receiving tray 10 employs multi-layer, multi-stage flow guidance to prevent leaks at the water source, guides a smooth water flow, reduces dripping noise, and increases user satisfaction.

[0044] The water tray 10 proposed in this invention can be installed on either a cabinet-type air conditioner or a wall-mounted type air conditioner. The shape of the air conditioner can be cylindrical or rectangular, and the shape of the water tray 10 can be square, circular, U-shaped, M-shaped, etc., without specific limitations. (See also...) Figures 1 to 3 For ease of description, it will be referred to as a water receiving tray 10 with a shape similar to that shown in the figure.

[0045] In the embodiments of the invention, please refer to Figures 2 to 12 The water receiving tray 10 includes a collection channel 10a, two guide channels 10b, and a plurality of first support ribs 10e. The two guide channels 10b are respectively connected to the two ends of the collection channel 10a. The plurality of first support ribs 10e are disposed in the guide channels 10b for supporting the heat exchanger 30. A water passage gap is formed between the first support ribs 10e and the bottom and / or sidewall of the guide channels 10b. The bottom of the guide channels 10b extends inclined toward the collection channel 10a to guide the water in the guide channels 10b to the collection channel 10a.

[0046] Specifically, the bottom of the guide channel 10b extends inclinedly towards the collection channel 10a, which can be a ramp 111, a step, or other regular or irregular water guiding channels. No specific limitation is made here, as long as it allows the flow in the guide channel 10b to be directed to the collection channel 10a. After assembly, both ends of the heat exchanger 30 are located above the two guide channels 10b. When the heat exchanger 30 operates at high speed, it generates a large amount of condensate. Most of the condensate flows into the collection channel 10a, while a small portion of the condensate generated on both sides of the heat exchanger 30 flows into the guide channels 10b on both sides of the water receiving tray 10, and then into the collection channel 10a for centralized drainage. The number of first support ribs 10e can be 2, 3, 4, 5, 6, etc., without specific limitation. Only one first support rib 10e should be provided on each of the two guide channels 10b to support the heat exchanger 30. The multiple first support ribs 10e can be in the shape of bosses, rectangles, strips, sharp corners, raised strips, squares, regular shapes, irregular shapes, etc., as long as they are used to support the two ends of the heat exchanger 30 away from the upper surface of the water receiving tray 10, so that the condensate of the heat exchanger 30 can flow smoothly into the guide groove 10b. There is no specific limitation here. The two ends of the heat exchanger 30 are supported by multiple first support ribs 10e. The multiple first support ribs 10e can raise the distance between the heat exchanger 30 and the guide groove 10b in the water receiving tray 10, so that the water flow is not blocked by the two ends of the heat exchanger 30 and flows smoothly into the guide groove 10b for drainage, thereby realizing drainage with a single layer of water receiving tray 10.

[0047] In this embodiment, a water-passing gap is formed between the first support rib 10e and the bottom and / or sidewall of the guide channel 10b. It is understood that when a water-passing gap is formed between the first support rib 10e and the bottom of the guide channel 10b, the first support rib 10e connects to the upper part of both sidewalls of the guide channel 10b, forming a water-passing gap with the bottom of the channel. When a water-passing gap is formed between the first support rib 10e and the sidewall of the guide channel 10b, the first support rib 10e is located at the bottom of the channel, and it can form a water-passing gap with one sidewall of the guide channel 10b, or it can form water-passing gaps with both sidewalls of the guide channel 10b. When a water-passing gap is formed between the first support rib 10e and both the bottom and sidewall of the guide channel 10b, the first support rib 10e is located on one sidewall of the guide channel 10b and suspended thereon, forming water-passing gaps with both the bottom and sidewall. The choice can be made according to requirements and is not specifically limited here.

[0048] Multiple first support ribs 10e not only support the heat exchanger 30 but also slow down water flow and reduce water noise. Understandably, when condensate from the heat exchanger 30 flows into the guide channel 10b, it possesses kinetic energy due to gravity. This kinetic energy increases as the flow proceeds, producing a gurgling sound. When the water encounters a first support rib 10e, it impacts the rib, instantly reducing its kinetic energy. By installing multiple first support ribs 10e in the guide channel 10b, the water impacts each rib, reducing its kinetic energy with each impact. This design allows the water to flow smoothly in the guide channel 10b, effectively reducing noise and improving the user experience.

[0049] Because the condensate on both sides of the heat exchanger 30 can be guided to the collection tank 10a through the water passage gap, the time that the condensate stays in the guide tank 10b is reduced, the drainage speed is accelerated, and thus ensures that even when the heat exchanger 30 operates at high speed and generates a large amount of condensate, it can still effectively drain the condensate, preventing the condensate from overflowing the edges of the water receiving pan 10. This solves the problem of existing double-layer water receiving pans 10' draining water from the upper edge openings to the lower layer of the double-layer water receiving pan 10'. This single-layer water receiving pan 10 can achieve drainage, which, compared with the existing double-layer water receiving pan 10', not only reduces the space occupied in the vertical direction, but also reduces the manufacturing cost of one layer of water receiving pan 10, reduces mold manufacturing costs and production and assembly costs, and improves the assembly efficiency of workers.

[0050] To reduce water noise, please refer to Figures 3 to 4 In this embodiment, the first support rib 10e is elongated. The first support rib 10e occupies less width, and more first support ribs 10e can be arranged on the guide channel 10b, resulting in more water impacts and a smoother water flow, thus reducing noise. Further, in this embodiment, the first support rib 10e is located at the bottom of the guide channel 10b, and the first support rib 10e forms a water passage gap with at least one side wall of the guide channel 10b. The first support rib 10e can form a water passage gap with one side wall of the guide channel 10b, or it can form water passage gaps with both side walls of the guide channel 10b; no specific limitation is made here. Continuing with the above embodiment, the first support rib 10e slopes downstream of the guide channel 10b from one end near one side wall. With this arrangement, water flows along the support ribs, and while the impact slows down, it also guides the flow, making the water flow smoother and reducing noise.

[0051] Please see Figure 2In this embodiment, the first support rib 10e is angled. Further, the first support rib 10e is disposed at the bottom of the guide channel 10b, and the first support rib 10e forms the water passage gap with at least one side wall of the guide channel 10b. The first support rib 10e may form a water passage gap with one side wall of the guide channel 10b, or it may form water passage gaps with both side walls of the guide channel 10b; no specific limitation is made here. To ensure that the sharp corner of the first support rib 10e faces the water flow direction for diversion, referring to the above embodiment, as follows... Figure 13 As shown, the first support rib 10e includes a first rib and a second rib. One end of the first rib is connected to one end of the second rib, and the distance between the first rib and the second rib gradually increases from the upstream to the downstream direction of the guide channel 10b. It can be understood that the first rib and the second rib combine to form the sharp corner of the first support rib 10e. This sharp corner receives the flowing condensate, reducing the weight and velocity of the condensate and lessening its impact on the first support rib 10e. Simultaneously, each time the condensate impacts the first support rib 10e, it reduces kinetic energy, slows the water flow, and diverts and guides the flow, ensuring the water flows smoothly into the collection channel 10a. This avoids generating water noise, thereby reducing the noise of the air conditioner during operation and resulting in a better user experience.

[0052] To ensure the heat exchanger 30 stands stably on the first support rib 10e and to guarantee the stability of the overall structure, please refer to [link to relevant documentation]. Figures 2 to 4 In this embodiment, the upper end of the first support rib 10e is flush with the upper end of the guide channel 10b. It is understood that the heat exchanger 30 is located at the upper end of the two guide channels 10b in the water receiving tray 10. The first support rib 10e detaches the heat exchanger 30 from the bottom of the guide channel 10b, making the heat exchanger 30 flush with the upper end of the guide channel 10b, which is beneficial for the stable installation of the heat exchanger 30. However, the two ends of the heat exchanger 30 should not block the upper end of the guide channel 10b, preventing some condensate from flowing into the guide channel 10b. Furthermore, the height of the first support rib 10e gradually increases from the upstream to the downstream direction of the guide channel 10b. The height of the first support rib 10e from the bottom of the channel to the upper end of the guide channel 10b gradually increases from upstream to downstream, ensuring the strength of the first support rib 10e in supporting the heat exchanger 30 and preventing the first support rib 10e from being broken because it is only located on the side wall of the guide channel 10b and is insufficient to support the weight of the heat exchanger 30.

[0053] To reduce water flow noise and provide users with a quiet and comfortable air conditioning experience, please refer to [link / reference]. Figures 2 to 4In this embodiment, the guide channel 10b and / or the collecting channel 10a form at least two ramps 111. It is understood that the number of ramps 111 can be two, three, four, etc., as long as the water has sufficient kinetic energy to flow along the ramps 111 to the collecting channel 10a for centralized drainage; no specific limitation is made here. When water flows on the guide channel 10b, it is guided along the multi-level ramps 111 into the drain outlet 101 of the collecting channel 10a for drainage. The multiple ramps 111 effectively prevent excessive kinetic energy of the water in the guide channel 10b, reducing noise. The condensate from the heat exchanger 30 flows into the collecting channel 10a through the support plate 102. To reduce water noise, please refer to [link to relevant documentation]. Figure 2 or Figure 4 The ramp 111 can also be set on the side wall of the collection tank 10a to transition the height of the collection tank 10a, dividing the original height into multiple layers. The water flows layer by layer along the upper surface of the support plate 102 to the collection tank 10a. This structure divides the original vertical height into layers, reducing the height of the water due to its own gravity and acceleration. By guiding the water through multiple layers, the height of the water flow is reduced, the water flow speed is slowed down, and the dripping noise is reduced.

[0054] A guide bar can be installed downstream of the slope 111. After the water in the upstream is accelerated by the slope 111, its kinetic energy is relatively large. The guide bar can effectively decelerate the water by impact. At the same time, the guide bar can guide the water flow, making the water flow smoother, thereby reducing water flow resistance and noise.

[0055] Please see Figure 4 In this embodiment, the water receiving tray 10 further includes a water receiving trough 10d, which is located between the two guide channels 10b. A partition plate 10c is provided between the water receiving trough 10d and the collecting channel 10a, and the partition plate 10c has a water passage hole 121. The collecting channel 10a and the water receiving trough 10d are connected through the water passage hole 121. It can be understood that the partition plate 10c divides the water receiving trough 10d and the collecting channel 10a. During the operation of the air conditioner, the air outlet frame 20 will generate condensate, which the water receiving trough 10d can collect. Simultaneously, the water in the water receiving trough 10d flows into the collecting channel 10a through the water passage hole 121, and the collecting channel 10a then discharges the water. This effectively prevents the air conditioner from overflowing and affecting the user experience.

[0056] The heat exchanger 30 is located on the outer periphery of the water receiving pan 10. To ensure the stability of the heat exchanger 30 support, please refer to [reference needed]. Figures 2 to 4In this embodiment, the collecting tank 10a has a rear enclosure facing away from the water receiving tank 10d. A support plate 102 protrudes from the inner side of the rear enclosure, and a second support rib 10f is provided on the upper surface of the support plate 102. The second support rib 10f supports the rear part of the heat exchanger 30, while the first support rib 10e supports the left and right parts of the heat exchanger 30. The second support rib 10f not only provides support but also guides the flow, allowing condensate generated in the rear part of the heat exchanger 30 to flow along the second support rib 10f to the collecting tank 10a for drainage. Figure 4 and Figure 7 As shown, the support plate 102 is provided with a PTC mounting groove 103. The PTC mounting groove 103 supplies power to the heater for fixed installation, ensuring the stability of the installation structure.

[0057] Please see Figures 2 to 4 In this embodiment, the collection tank 10a is provided with a drain outlet 101. The drain outlet 101 is used to discharge water from the collection tank 10a, effectively controlling the water level in the receiving pan 10 and preventing condensate from flowing out of the receiving pan 10. However, the collection tank 10a has a limited volume and can only hold a limited amount of water. Although the collection tank 10a is provided with a drain outlet 101, the maximum drainage capacity of the drain outlet 101 per unit time is limited. For example, in the special case where too much condensate flows into the collection tank 10a, the amount of water entering the second receiving pan 10d per unit time is too large, and the amount of water discharged by the drain outlet 101 per unit time is less than the amount of water entering the collection tank 10a per unit time, at which point the water level will continuously increase. To prevent water from flowing out of the receiving pan 10, an overflow outlet can be considered to increase the drainage speed of the collection tank 10a. The height of the overflow outlet should be higher than the drain outlet 101, but should not exceed the overall height of the receiving pan 10.

[0058] The present invention also proposes an air conditioner, which includes a water receiving tray 10 and a heat exchanger 30. The heat exchanger 30 is U-shaped or V-shaped, and its two sides are respectively disposed on the two guide grooves 10b. The specific structure of the water receiving tray 10 is as described in the above embodiments. Figure 4 These will not be elaborated upon here. Please refer to [link / reference]. Figures 4 to 12 To accommodate the U-shape or V-shape of the heat exchanger 30 and reduce its space requirement, the water receiving tray 10 can be configured in a U-shape or V-shape. Condensate generated on both sides of the heat exchanger 30 flows into the two guide channels 10b and is simultaneously drained into the collection channel 10a. The water receiving tray 10 is located below the heat exchanger 30 and the air outlet frame 20, which is located in front of the heat exchanger 30. Above the two guide channels 10b, the air outlet frame 20 has a drainage section 20a, which consists of two interconnected drainage channels to drain water from the air outlet frame 20 into the guide channels 10b.

[0059] Specifically, the condensate from the air outlet frame 20 flows into the water collection tank 10d, and the condensate from the heat exchanger 30 flows into the collection tank 10a via the guide channel 10b or the support plate 102. The drainage sections 20a on both sides of the bottom of the air outlet frame 20 serve two purposes: firstly, they collect the condensate from the refrigerant pipes, directing it into the guide channel 10b, and then into the collection tank 10a for drainage; secondly, they make the entire unit more compact, avoiding the need for a separate water collection and drainage device under the air outlet frame 20, which would increase the overall height and occupy space. This structure effectively drains condensate from multiple components while reducing the space occupied by the entire unit and minimizing water noise, providing users with an excellent user experience.

[0060] To ensure that the condensate in the air outlet frame 20 flows smoothly to the water collection tank 10d, thereby reducing the amount of condensate stagnating in the air outlet frame 20, the bottom plate of the air outlet frame 20 can be designed as a guide slope. The condensate can flow to the water collection tank 10d due to its own gravity. This structure is simple, easy to implement, and effectively prevents water droplets from stagnating on the air outlet frame 20, thus preventing insufficient drainage and helping to maintain the drainage stability of the entire drainage system.

[0061] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
