Description

Technical Field

[0001] This invention relates to the field of air conditioning, and more specifically, to a water tray structure and an air conditioner having the same. Background Technology

[0002] Currently, the drip tray of a cabinet air conditioner serves to collect condensate and protect electrical components. Existing air conditioner drip trays typically collect condensate and drain it through the drain hole.

[0003] During the drainage process, unfiltered lint, dust, and other dirt adhere to the drain pan along with the condensate. Some of this dirt is discharged from the air conditioner with the condensate, but most of it accumulates and cannot drain. Over time, this buildup will clog the drain hole. Furthermore, the inability to drain a large amount of condensate can cause water to enter electrical components, potentially leading to electrical safety hazards.

[0004] Traditional air conditioners have a filter screen in the drip tray to filter out dirt and prevent clogging. However, this method requires regular cleaning of the air conditioner's filter screen, which is time-consuming and laborious. Summary of the Invention

[0005] The main objective of this invention is to provide a water tray structure and an air conditioner having the same, so as to solve the problem that the water tray of the air conditioner in the prior art is prone to accumulating dirt.

[0006] To achieve the above objectives, according to one aspect of the present invention, a water receiving tray structure is provided, comprising: a first water receiving tray having a first receiving cavity for containing liquid and a drain outlet communicating with the first receiving cavity; and a second water receiving tray having a second receiving cavity for containing liquid, wherein at least a portion of the second water receiving tray is adjustablely disposed above the bottom wall of the first receiving cavity, such that when the liquid in the second receiving cavity reaches a predetermined amount, the second receiving cavity communicates with the first receiving cavity, so that the liquid in the second receiving cavity falls into the first receiving cavity under the action of gravity.

[0007] Furthermore, the second water receiving tray is installed on the first water receiving tray; and / or the second water receiving tray is installed inside the first receiving cavity.

[0008] Furthermore, a drainage cavity is provided on the bottom wall of the first receiving cavity. The drainage cavity has an installation section and a drainage section. The drain outlet is located at the bottom of the drainage section, and the second water receiving tray is installed in the installation section. The bottom wall of the drainage section is lower than the bottom wall of the installation section.

[0009] Furthermore, the bottom wall of the drainage cavity section has a drainage wall section for connection with the bottom wall of the installation cavity section, the drainage wall section being inclined to the horizontal plane.

[0010] Furthermore, the second water receiving tray is oscillatingly arranged so that when the liquid in the second receiving cavity reaches a predetermined amount, the liquid in the second receiving cavity is poured into the first receiving cavity by oscillating the second water receiving tray.

[0011] Furthermore, the first water receiving tray is provided with a first hinge portion, and the second water receiving tray is provided with a second hinge portion. The first hinge portion and the second hinge portion cooperate to allow the second water receiving tray to swing around a predetermined axis.

[0012] Furthermore, one of the first hinge portion and the second hinge portion is a hinge protrusion, and the other of the first hinge portion and the second hinge portion is a hinge groove, with the hinge protrusion inserted into the hinge groove; and / or there are multiple first hinge portions and multiple second hinge portions, with multiple first hinge portions and multiple second hinge portions arranged in a one-to-one correspondence; wherein, at least one second hinge portion is provided on each of the two opposite side walls of the second water receiving tray.

[0013] Furthermore, the second water receiving tray includes a water storage section and a pouring section. The second receiving cavity has a first cavity section disposed in the water storage section and a second cavity section disposed in the pouring section, with the first cavity section and the second cavity section communicating with each other. The bottom surface of the pouring section is inclined to the bottom surface of the water storage section so that when the liquid in the second receiving cavity reaches a predetermined amount, the liquid in both the first cavity section and the second cavity section is poured out by the pouring section through the flipping of the second water receiving tray.

[0014] Furthermore, along the distribution direction of the pouring section and the water storage section, the length of the pouring section is greater than the length of the water storage section, and the second water receiving tray is oscillatingly arranged around a predetermined axis, which is located at the connection between the pouring section and the water storage section.

[0015] Furthermore, the second water receiving tray is oscillatingly arranged about a predetermined axis, and the second water receiving tray has a center line perpendicular to its extension direction and passing through its center point, with the predetermined axis located on one side of the center line.

[0016] Furthermore, the second receiving cavity has a water outlet section; when the second water receiving tray is in the state of pouring liquid, the flow cross section of the water outlet section gradually decreases along the liquid flow direction in the second water receiving tray.

[0017] Furthermore, the second receiving cavity has a water outlet located on the side of the second water receiving tray near the drain outlet; and / or when the second water receiving tray is in the state of pouring liquid, the water outlet is disposed facing the bottom wall of the first receiving cavity.

[0018] Furthermore, the second water receiving tray has a water outlet hole communicating with the second receiving cavity. The water receiving tray structure also includes a water outlet valve, which is installed in the water outlet hole so that when the liquid in the second receiving cavity reaches a predetermined amount, the liquid in the second receiving cavity is controlled to flow out of the water outlet hole by opening the water outlet valve.

[0019] Furthermore, the water receiving tray structure also includes a water volume measuring component, which is disposed in the second receiving cavity to detect the water volume information in the second receiving cavity and control the opening or closing of the water outlet valve based on the water volume information.

[0020] Furthermore, the water volume measuring component is a weighing sensor, or a float-type water level gauge.

[0021] According to another aspect of the present invention, an air conditioner is provided, including a housing and a water tray structure disposed within the housing, wherein the water tray structure is the water tray structure described above.

[0022] According to another aspect of the invention, the air conditioner also includes an air inlet component, on which a water tray structure is mounted.

[0023] The water collection tray structure of this invention includes a first water collection tray and a second water collection tray. The first water collection tray has a first receiving cavity for containing liquid and a drain outlet communicating with the first receiving cavity. The second water collection tray has a second receiving cavity for containing liquid, and at least a portion of the second water collection tray is adjustablely positioned above the bottom wall of the first receiving cavity. Thus, when the liquid in the second receiving cavity reaches a predetermined amount, the second receiving cavity is connected to the first receiving cavity, allowing the liquid in the second receiving cavity to fall into the first receiving cavity under gravity. Therefore, by employing a combination of the first and second water collection trays, this invention enables the first water collection tray to collect condensate from the air conditioner. Furthermore, when the liquid in the second water collection tray reaches a predetermined amount, adjusting the position of the second water collection tray allows the liquid in the second receiving cavity to be poured into the first receiving cavity, flushing the inner wall of the first receiving cavity and cleaning it. This prevents blockage of the drain outlet and eliminates the need for cleaning the water collection tray itself. Furthermore, the second drip tray allows dirt to settle inside, reducing the amount of dirt entering the first drip tray and thus solving the problems of dirt accumulation in the drip tray and blockage of the drain in existing air conditioners.

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] This invention provides a water receiving tray structure, please refer to... Figures 1 to 6 The water receiving tray structure includes: a first water receiving tray 10, which has a first receiving cavity 11 for containing liquid and a drain outlet 12 communicating with the first receiving cavity 11; and a second water receiving tray 20, which has a second receiving cavity 21 for containing liquid. At least a portion of the second water receiving tray 20 is adjustablely disposed above the bottom wall of the first receiving cavity 11 so that when the liquid in the second receiving cavity 21 reaches a predetermined amount, the second receiving cavity 21 communicates with the first receiving cavity 11, so that the liquid in the second receiving cavity 21 falls into the first receiving cavity 11 under the action of gravity.

[0035] The water receiving tray structure of this invention includes a first water receiving tray 10 and a second water receiving tray 20. The first water receiving tray 10 has a first receiving cavity 11 for containing liquid and a drain outlet 12 communicating with the first receiving cavity 11. The second water receiving tray 20 has a second receiving cavity 21 for containing liquid, and at least a portion of the second water receiving tray 20 is adjustablely positioned above the bottom wall of the first receiving cavity 11. Thus, when the liquid in the second receiving cavity 21 reaches a predetermined amount, the second receiving cavity 21 communicates with the first receiving cavity 11, allowing the liquid in the second receiving cavity 21 to fall into the first receiving cavity 11 under the influence of gravity. As can be seen, by employing a combination of a first drip tray 10 and a second drip tray 20, the present invention enables the first drip tray 10 to collect condensate from the air conditioner. Furthermore, when the liquid in the second drip tray 20 reaches a predetermined level, adjusting the position of the second drip tray 20 allows the liquid in the second receiving cavity 21 to be poured into the first receiving cavity 11, flushing the inner wall of the first receiving cavity 11 and cleaning it. This prevents blockage of the drain outlet 12, eliminating the need for cleaning the drip tray itself. Moreover, the second drip tray 20 collects the condensate, causing dirt to settle within it and reducing the amount of dirt entering the first drip tray 10. This solves the problems of dirt accumulation in the drip trays and blockage of the drain outlet 12 in existing air conditioners.

[0036] As can be seen, the water tray structure of the present invention is a combination of the first water tray 10 and the second water tray 20. The water tray structures in the prior art are mainly traditional water tray structures and cleaning systems. Self-cleaning mainly refers to independent cleaning devices or prevention of dirt accumulation. The water tray structure of the present invention mainly relies on the periodic flushing of the accumulated dirt by the water tray structure to achieve self-cleaning.

[0037] like Figures 1 to 3 As shown, the combination of the first water receiving tray 10 and the second water receiving tray 20 is as follows: the second water receiving tray 20 is installed on the first water receiving tray 10; and / or the second water receiving tray 20 is installed inside the first receiving cavity 11. In this way, the installation and water receiving cooperation between the first water receiving tray 10 and the second water receiving tray 20 can be achieved relatively easily.

[0038] To achieve the installation of the second water receiving tray 20, such as Figure 1 and Figure 2 As shown, a drainage recess 13 is provided on the bottom wall of the first receiving cavity 11. The drainage recess 13 has an installation section 131 and a drainage section 132. The drain outlet 12 is located at the bottom of the drainage section 132, and the second water receiving tray 20 is installed inside the installation section 131. The bottom wall of the drainage section 132 is lower than the bottom wall of the installation section 131. This facilitates the flow of liquid from the second receiving cavity 21 to the drainage section 132.

[0039] In this embodiment, as Figure 1 As shown, the bottom wall of the drainage chamber section 132 has a drainage wall section 1321 for connection with the bottom wall of the mounting chamber section 131, and the drainage wall section 1321 is inclined to the horizontal plane. By providing the drainage wall section 1321, liquid can be conveniently drained into the drainage chamber section 132.

[0040] To facilitate the flushing of the inner wall of the first receiving cavity 11 of the first water receiving tray 10 by the liquid in the second water receiving tray 20, there are various implementation methods, which are described in detail below:

[0041] Example 1:

[0042] like Figure 1 and Figure 2 As shown, the second water receiving tray 20 is oscillatingly arranged so that when the liquid in the second receiving cavity 21 reaches a predetermined amount, the liquid in the second receiving cavity 21 is poured into the first receiving cavity 11 by oscillating the second water receiving tray 20.

[0043] in, Figure 1 The second water receiving tray 20 is in its initial state. Figure 2 The second water receiving tray 20 is tilted.

[0044] In addition, in order to achieve the return of the liquid in the second water tray 20, the water receiving structure also includes a reset member. The reset member is connected to both the first water tray 10 and the second water tray 20, so that after the liquid in the second water tray 20 is poured out, it will automatically return to its initial state under the action of the reset member.

[0045] To achieve a rotatable connection between the second water receiving tray 20 and the first water receiving tray 10, such as Figure 4 and Figure 6 As shown, the first water receiving tray 10 is provided with a first hinge portion 14, and the second water receiving tray 20 is provided with a second hinge portion 22. The first hinge portion 14 and the second hinge portion 22 cooperate to make the second water receiving tray 20 swing around a predetermined axis.

[0046] Specifically, one of the first hinge portion 14 and the second hinge portion 22 is a hinge protrusion, and the other of the first hinge portion 14 and the second hinge portion 22 is a hinge groove, with the hinge protrusion inserted into the hinge groove; and / or there are multiple first hinge portions 14 and multiple second hinge portions 22, with multiple first hinge portions 14 and multiple second hinge portions 22 arranged in a one-to-one correspondence; wherein, at least one second hinge portion 22 is provided on each of the two opposite side walls of the second water receiving tray 20.

[0047] To facilitate the pouring of the second water receiving tray 20, such as Figure 1 , Figure 2 and Figure 5As shown, the second water receiving tray 20 includes a water storage section 23 and a pouring section 24. The second receiving cavity 21 has a first cavity section 211 disposed in the water storage section 23 and a second cavity section 212 disposed in the pouring section 24. The first cavity section 211 and the second cavity section 212 are in communication. The bottom surface of the pouring section 24 is inclined to the bottom surface of the water storage section 23 so that when the liquid in the second receiving cavity 21 reaches a predetermined amount, the liquid in the first cavity section 211 and the second cavity section 212 are poured out by the pouring section 24 through the flipping of the second water receiving tray 20.

[0048] Among them, such as Figure 1 As shown, when the second water receiving tray 20 is in its initial state, the second water receiving tray 20 is tilted to the horizontal plane and its free end faces the orientation; as Figure 2 As shown, when the second water receiving tray 20 is in a tilted state, the second water receiving tray 20 is tilted to the horizontal plane and the free end is facing downward.

[0049] Preferably, the inner wall surface of the first receiving cavity 11 has a sloping surface, such as... Figure 2 As shown, when the second water receiving tray 20 is in a tilted state, the bottom wall of the tilting part 24 is in contact with the tilting slope.

[0050] To facilitate the automatic emptying of the second water receiving tray 20 once the liquid level reaches a predetermined amount, such as... Figure 3 and Figure 4 As shown, along the distribution direction of the pouring section 24 and the water storage section 23, the length of the pouring section 24 is greater than the length of the water storage section 23. The second water receiving tray 20 is oscillatingly arranged around a predetermined axis, which is located at the connection between the pouring section 24 and the water storage section 23. This arrangement allows the center of gravity of the second water receiving tray 20 to be eccentrically positioned with respect to the predetermined axis. Consequently, when the liquid level in the second water receiving tray 20 reaches a predetermined value, the liquid pressure in the second water receiving tray 20 causes the second water receiving tray 20 to rotate automatically.

[0051] In this embodiment, the rotation axis of the second water receiving tray 20 is set eccentrically as follows: Figure 4 As shown, the second water receiving tray 20 is oscillatingly arranged around a predetermined axis. The second water receiving tray 20 has a center line perpendicular to its extension direction and passing through its center point, and the predetermined axis is located on one side of the center line.

[0052] In this embodiment, as Figure 4 As shown, the second receiving cavity 21 has a water outlet section 25; when the second water receiving tray 20 is in the state of pouring liquid, the flow cross section of the water outlet section 25 gradually decreases along the liquid flow direction in the second water receiving tray 20. In this way, it is convenient for the liquid in the second receiving cavity 21 to be discharged in a concentrated manner.

[0053] To maximize the flushing of drain outlet 12, such as Figure 1 and Figure 2As shown, the second receiving cavity 21 has a water outlet 26, which is located on the side of the second water receiving tray 20 near the drain outlet 12; and / or when the second water receiving tray 20 is in the state of pouring liquid, the water outlet 26 is disposed towards the bottom wall of the first receiving cavity 11.

[0054] Example 2:

[0055] This embodiment adopts a different embodiment from Embodiment 1. The second water receiving tray 20 has a water outlet hole communicating with the second receiving cavity 21. The water receiving tray structure also includes a water outlet valve, which is installed in the water outlet hole so that when the liquid in the second receiving cavity 21 reaches a predetermined amount, the liquid in the second receiving cavity 21 is controlled to flow out of the water outlet hole by opening the water outlet valve.

[0056] In order to measure the water volume in the second water receiving tray 20, the water receiving tray structure also includes a water volume measuring component, which is set in the second receiving cavity 21 to detect the water volume information in the second receiving cavity 21 and control the opening or closing of the water outlet valve based on the water volume information.

[0057] The water measurement component in this embodiment can be implemented in different ways, as follows:

[0058] In one implementation, the water measurement component is a weighing sensor.

[0059] In another implementation, the water volume measuring component is a float-type water level gauge.

[0060] The present invention also provides an air conditioner, such as Figure 6 As shown, the air conditioner includes a housing 30 and a water tray structure disposed within the housing 30, the water tray structure being the aforementioned water tray structure.

[0061] To facilitate the installation of the water tray structure, such as Figure 6 As shown, the air conditioner also includes an air intake component, and a water tray structure is installed on the air intake component.

[0062] The water receiving tray structure in this invention solves the following technical problems:

[0063] 1. To prevent the drain outlet of the first water receiving tray 10 from becoming clogged;

[0064] 2. Protect the electrical components of the air conditioner;

[0065] 3. By adopting a combination of the first water receiving tray 10 and the second water receiving tray 20, the second water receiving tray 20 is used for automatic flushing and cleaning, saving the process of cleaning the filter screen in the existing water receiving tray structure.

[0066] As can be seen, the water tray structure in this invention combines the first water tray 10 and the second water tray 20 to achieve the function of the first water tray 10 receiving the condensate inside the air conditioner, while the second water tray 20 relies on the shift of the center of gravity to flush the first water tray 10, thereby achieving the effect of automatically cleaning the first water tray 10 and preventing the drain outlet from being blocked, saving customers and maintenance personnel the process of cleaning the water tray filter.

[0067] The water collection tray structure in this invention utilizes condensate water for self-cleaning to prevent dirt accumulation, and relies on potential energy to increase the water flow velocity to prevent dirt buildup; the second water collection tray 20 achieves rotation and return to its original position by storing condensate water and shifting its own center of gravity, thereby preventing blockage at the drain outlet. Furthermore, it can also flush and clean the drainage pipes to a certain extent.

[0068] This invention achieves all the functions of the overall component through a novel water collection tray structure that combines a first water collection tray 10 and a second water collection tray 20. This water collection tray structure is assembled in a cabinet air conditioner. The first water collection tray 10 is fixed to the air inlet component of the air conditioner, and the second water collection tray 20 is installed behind the drain outlet inside the first water collection tray 10. The second water collection tray 20 is engaged in the pivot groove (hinge groove) of the first water collection tray 10 via a pivot (hinged protrusion), allowing the second water collection tray 20 to rotate freely around the pivot.

[0069] The main function of the first water receiving pan 10 is to collect the condensate inside the air conditioner. The condensate flows into the first water receiving pan 10 through the evaporator component of the air conditioner. In addition, some water that enters the air conditioner from the outside due to human factors reaches the first water receiving pan 10 through the internal drainage structure of the air conditioner. The main function of the second drip tray 20 is to collect the water from the first drip tray 10. It has a water storage function. By storing the water in the first drip tray 10 in the second drip tray 20, lint, dust, and other contaminants that flow into the drip tray along with the condensate will accumulate in the second drip tray 20. When the water level in the second drip tray 20 reaches a certain position, the second drip tray 20 will "tilt" forward due to its center of gravity shifting forward. At this time, the water accumulated in the second drip tray 20 will pour towards the drain outlet of the first drip tray. During this process, lint, dust, and other dirt will flow with the water to the drain outlet and be discharged from the air conditioner. Because the water flow rate is relatively high during the pouring process, it will have a flushing effect on the drain outlet of the first drip tray 10. Even if some dirt is not discharged and adheres to the vicinity of the drain outlet, this flushing process can clean and discharge the dirt that has not been discharged, thereby achieving a self-cleaning function.

[0070] After the second water tray 20 "empties" and drains the water, it automatically "returns" to its original position to continue storing water due to its center of gravity being closer to the rear. This water storage and drainage cycle repeats continuously, achieving self-cleaning of the air conditioner's water tray. Because dirt is promptly discharged, there is no accumulation of dirt at the drain outlet, thus preventing blockages. This method is effective and stable over a long period, further enhancing the safety performance of electrical components. The self-cleaning function also eliminates the need for a filter screen in the water tray component, saving the tedious work of cleaning filters.

[0071] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0072] The water receiving tray structure of this invention includes a first water receiving tray 10 and a second water receiving tray 20. The first water receiving tray 10 has a first receiving cavity 11 for containing liquid and a drain outlet 12 communicating with the first receiving cavity 11. The second water receiving tray 20 has a second receiving cavity 21 for containing liquid, and at least a portion of the second water receiving tray 20 is adjustablely positioned above the bottom wall of the first receiving cavity 11. Thus, when the liquid in the second receiving cavity 21 reaches a predetermined amount, the second receiving cavity 21 communicates with the first receiving cavity 11, allowing the liquid in the second receiving cavity 21 to fall into the first receiving cavity 11 under the influence of gravity. As can be seen, by employing a combination of a first drip tray 10 and a second drip tray 20, the present invention enables the first drip tray 10 to collect condensate from the air conditioner. Furthermore, when the liquid in the second drip tray 20 reaches a predetermined level, adjusting the position of the second drip tray 20 allows the liquid in the second receiving cavity 21 to be poured into the first receiving cavity 11, flushing the inner wall of the first receiving cavity 11 and cleaning it. This prevents blockage of the drain outlet 12, eliminating the need for cleaning the drip tray itself. Moreover, the second drip tray 20 collects the condensate, causing dirt to settle within it and reducing the amount of dirt entering the first drip tray 10. This solves the problems of dirt accumulation in the drip trays and blockage of the drain outlet 12 in existing air conditioners.

[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
