In the hot and humid season, the humidity in the data center room will be relatively high, and the dew point temperature will also be relatively high. If the evaporator surface temperature of the running air conditioning unit is lower than the dew point temperature in the room environment, more condensed water will be generated when the return air flows through the evaporator, and flow vertically along the evaporator fins to the bottom of the evaporator.

[0030] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0031] Additionally, in the following description, specific details are provided to provide a thorough understanding of the embodiments. However, one skilled in the art will appreciate that the aspects described may be practiced without these specific details.

[0032] Combined with reference Figure 1 and Figure 2 In the first embodiment of the present application, a double-layer water receiving tray is provided, including: a first water receiving tray body 1, an outer baffle 12 is arranged on the first water receiving tray body 1, and the first water receiving tray body 1 and the outer baffle 12 form a water holding cavity; a liquid level sensor 14 is arranged on the outer baffle 12; a second water receiving tray 2, the second water receiving tray 2 includes a water inlet 21 and a water outlet 22 that are connected to each other, the water inlet 21 is connected to the water holding cavity, and the water outlet 22 is located below the first water receiving tray body 1; a drain pipe 3, connected to the water outlet 22, and used to discharge the liquid in the second water receiving tray 2; a water pump is arranged on the drain pipe 3, and the water pump (not shown in the figure) is connected to the liquid level sensor 14, and is used to adjust the water pressure of the drain pipe 3.

[0033] Among them, the first water receiving tray body 1 serves as the bottom, and the outer baffle 12 serves as the outer wall, together forming a water holding cavity; the shape of the first water receiving tray body 1 can be set according to actual needs, and can be specifically circular, elliptical, square, trapezoidal, triangular, etc.

[0034] The second water receiving tray 2 is a hollow cavity structure. The top of the second water receiving tray 2 is provided with a water inlet 21 connected to the water holding cavity of the first water receiving tray main body 1, and the side or bottom of the second water receiving tray 2 is provided with a water outlet 22 connected to the drain pipe 3. Specifically, the second water receiving tray 2 can be a horizontally arranged hollow cylinder, hollow rectangular parallelepiped or other structure. The structure can be arranged according to actual needs. The horizontal arrangement can increase its water storage capacity at the same height, prevent the overall height of the double-layer water receiving tray from being too high, and facilitate it to be arranged at the bottom of the air-conditioning unit for use.

[0035] The water inlet 21 of the second water receiving tray 2 is located at one end of the first water receiving tray body 1 and is connected to the first water receiving tray body 1; the water outlet 22 is preferably arranged at the bottom of the second water receiving tray 2, so that the liquid can flow out from the water inlet 21 and the water outlet 22 under the action of gravity. The water pressure of the drain pipe 3 can be adjusted by opening and closing the water pump and adjusting the working power of the water pump, thereby adjusting the drainage efficiency of the drain pipe 3. The liquid level sensor 14 is arranged on the outer baffle 12, and can detect the change of the accumulated water level in the first water receiving tray body 1 and the second water receiving tray 2. Through the electrical connection with the water pump, the drainage efficiency is adjusted to drain the accumulated condensed water as soon as possible, and prevent the liquid from overflowing from the double-layer water receiving tray and leaking.

[0036] The bottom of the first water receiving pan body 1, the bottom of the second water receiving pan 2 and the outer side of the outer baffle 12 can be glued with thermal insulation cotton to prevent the double-layer water receiving pan from being too cold due to contact with low-temperature condensed water, and to prevent condensed water on the outside of the double-layer water receiving pan from dripping to the bottom of the air-conditioning unit, causing the risk of water leakage.

[0037] Combined with reference Figure 3 , a double-layer water receiving tray of the present embodiment includes a first water receiving tray body 1 and a second water receiving tray 2, and liquid can flow into the second water receiving tray 2 from the water holding cavity formed by the first water receiving tray body 1 and the outer baffle 12, and then be discharged through the drain pipe 3; the double-layer water receiving tray can be arranged at the bottom of the evaporator and the blower 5 of the air-conditioning unit, and is used to discharge the condensed water of the air-conditioning unit; the second water receiving tray 2 is located below the first water receiving tray body 1, and can be arranged by the height difference, so that the amount of water accumulated in the first water receiving tray body 1 is small and the liquid level is low, which can increase the water storage capacity of the double-layer water receiving tray, prevent the accumulated water from contacting with the air-conditioning components due to excessive water accumulation in the double-layer water receiving tray and thus causing damage to the components, and reduce the risk of water floating and leakage caused by the reduced height difference between the accumulated water surface and the blower 5; at the same time, the water level of the accumulated water in the double-layer water receiving tray can be measured by the liquid level sensor 14, and the working power of the water pump can be started or increased after the accumulated water height reaches a certain value, so that the accumulated water can be quickly discharged from the drain pipe 3, thereby improving the drainage efficiency.

[0038] Combined with reference Figure 4 and Figure 5 In some embodiments, an evaporator support 11 is provided on the first water receiving tray body 1. Specifically, the evaporator support 11 is located on the inner side of the outer baffle 12, and is used to support the evaporator. The height of the evaporator is raised by setting the height of the evaporator support 11, so that the condensed water in the evaporator can flow out under the action of gravity, and the condensed water of the evaporator can be collected. The top of the evaporator support 11 is horizontal, which is convenient for placing the evaporator.

[0039] The evaporator support 11 is preferably fitted with the outer baffle 12, and the evaporator support 11 and the condensed water on the evaporator support 11 can be limited by the outer baffle 12 to prevent leakage; at the same time, it is convenient for the condensed water to flow directly from the evaporator support 11 to the first water receiving pan body 1 without being blocked by the evaporator support 11, and then flow into the second water receiving pan 2 and be discharged through the drain pipe 3, shortening the flow path of the condensed water and improving the drainage efficiency. The evaporator support 11 can be a cavity structure, and the top of the evaporator support 11 can be provided with a plurality of through holes connected to the internal cavity thereof, so that the condensed water in the evaporator can flow into the internal cavity under the action of gravity, and then flow into the water holding cavity of the first water receiving pan body 1.

[0040] Furthermore, a plurality of second through holes 115 are provided on a side of the evaporator support 11 close to the water inlet 21, and a plurality of first through holes 114 are provided on a side of the evaporator support 11 away from the water inlet 21. Condensed water falling to the side of the evaporator support 11 away from the water inlet 21 can pass through the first through hole 114 and the second through hole 115, through the evaporator support 11, and thus enter the water inlet 21, which can reduce the increase in the amount of water accumulated on the first water receiving tray body 1 due to the obstruction of the evaporator support 11, and prevent water floating and water leakage. Specifically, the first through hole 114 and the second through hole 115 are staggered to avoid water floating under the action of airflow.

[0041] Furthermore, the diameter of the second through hole 115 increases gradually in the direction close to the water inlet 21; the diameter of the first through hole 114 increases gradually in the direction away from the water inlet 21. The setting of the diameter of the first through hole 114 facilitates the condensed water to flow into the evaporator support 11 in the direction close to the water inlet 21, and reduces the condensed water from the evaporator support 11 to flow in the opposite direction away from the water inlet 21; and the setting of the diameter of the second through hole 115 facilitates the condensed water to flow in the direction close to the water inlet 21, and reduces the condensed water from the direction away from the water inlet 21 to flow into the evaporator support 11; the combination of the two is conducive to further allowing the condensed water to pass through the evaporator support 11 to flow to the water inlet 21, or to further allowing the condensed water in the evaporator support 11 to flow to the water inlet 21.

[0042] In some embodiments, the evaporator support member 11 includes a first support member 111 and a second support member 112 connected to each other; the first support member 111 and the second support member 112 are both in contact with the outer baffle 12. The first support member 111 and the second support member 112 and the condensed water thereon can be limited by the outer baffle 12 to prevent leakage. The extension lines of the first support member 111 and the second support member 112 intersect to form an angle, which can facilitate the horizontal placement of the evaporator, improve the stability of the evaporator, and reduce the space occupied by the evaporator support member 11 for the water storage cavity, so that the water storage cavity has sufficient water storage capacity. The first support member 111 and the second support member 112 can both be cavity structures to provide sufficient liquid storage space for the water storage cavity.

[0043] The first support member 111 and the second support member 112 can both abut against the outer baffle plate 12 through the side wall away from the water inlet 21, thereby fixing the positions of the first support member 111 and the second support member 112. In addition, the first support member 111 can be provided with a first abutting portion 1111 at one end away from the second support member 112, and abut against the outer baffle plate 12 through the first abutting portion 1111; the second support member 112 can be provided with a second abutting portion 1121 at one end away from the first support member 111, and abut against the outer baffle plate 12 through the second abutting portion 1121. Specifically, the outer baffle plate 12 can be provided with a snap-fitting protrusion at the positions corresponding to the first abutting portion 1111 and the second abutting portion 1121, thereby fixing the positions of the first abutting portion 1111 and the second abutting portion 1121, thereby fixing the position of the evaporator support member 11.

[0044] Furthermore, a first opening 1112 is provided at one end of the first support member 111 away from the second support member 112, and a second opening 1122 is provided at one end of the second support member 112 away from the first support member 111, so that the liquid in the first support member 111 and the second support member 112 can be conveniently discharged through the provision of the openings. Specifically, the first opening 1112 and the second opening 1122 are respectively located on the inner side of the first support member 111 and the second support member 112, i.e., on the side close to the water inlet 21, so that the liquid in the first support member 111 and the second support member 112 can be conveniently discharged into the water inlet 21; and the first abutting portion 1111 and the second abutting portion 1121 are respectively located on the outer side of the first support member 111 and the second support member 112, i.e., on the side away from the water inlet 21, so that the liquid in the first support member 111 and the second support member 112 can flow toward the water inlet 21 through the first opening 1112 and the second opening 1122 while performing abutment limiting.

[0045] The second through hole 115 may be located at a side of the first support member 111 and the second support member 112 close to the water inlet 21 , and the first through hole 114 may be located at a side of the first support member 111 and the second support member 112 away from the water inlet 21 .

[0046] The evaporator support member 11 may further include a connector 113, which is disposed on the first water receiving tray body 1 and is used to connect the first support member 111 and the second support member 112. Specifically, the connector 113 is located on the first water receiving tray body 1 at a position away from the water inlet 21, and is used to connect one end of the first support member 111 away from the water inlet 21 and one end of the second support member 112 away from the water inlet 21; the connector 113 may also be a cavity structure to provide sufficient liquid storage space for the water storage cavity.

[0047] Combined with reference Figure 2 and Figure 6 In some embodiments, the double-layer water tray further includes a water tray support 4, the water tray support 4 is located below the first water tray body 1, and the water tray support 4 includes a first support leg 41 and a second support leg 42, the second support leg 42 is arranged on the side of the first water tray body 1 close to the water inlet 21, and the first support leg 41 is arranged on the side of the first water tray body 1 away from the water inlet 21. The water tray support 4 (including the first support leg 41 and the second support leg 42) is used to support the water tray, and the angle between the first water tray body 1 and the horizontal plane can be adjusted by the height difference between the first support leg 41 and the second support leg 42, so as to facilitate the flow of liquid into the water inlet 21. Preferably, the angle between the first water tray body 1 and the horizontal plane is 0 degrees to prevent the evaporator from tipping over and being damaged due to long-term tilting.

[0048] Specifically, the water receiving tray support 4 also includes a third supporting foot 43, and the third supporting foot 43 is arranged on the side of the first water receiving tray body 1 close to the water inlet 21, and the second supporting foot 42 and the third supporting foot 43 are respectively located at the two ends of the side of the first water receiving tray body 1 close to the water inlet 21, so as to form a three-legged stable structure with the first supporting foot 41, thereby improving the stability of the first water receiving tray body 1 and the double-layer water receiving tray.

[0049] Combined with reference Figure 7, further, the water receiving tray support 4 also includes a lifter 6, the lifter 6 connects the first support leg 41 and the first water receiving tray body 1, and the lifter 6 is electrically connected to the liquid level sensor 14. When the liquid level sensor 14 senses that the water level on the first water receiving tray body 1 or the water level in the second water receiving tray 2 reaches a certain height value, the lifter 6 can be used to lift one side of the first water receiving tray body 1, so that the height of the first water receiving tray body 1 away from the water inlet 21 is greater than the height of the side close to the water inlet 21, so that the liquid flows into the water inlet 21 and flows out through the water outlet 22 and the drain pipe 3; and when the water level on the first water receiving tray body 1 or the water level in the second water receiving tray 2 drops, the lifter 6 returns to its original state, so that the first water receiving tray body 1 is level with the horizontal plane, preventing the evaporator from tipping over and being damaged due to long-term tilting. Specifically, the lifter 6 includes a driving member for driving its lifting movement, and the driving member of the lifter 6 is electrically connected to the liquid level sensor 14.

[0050] In some embodiments, the double-layer water receiving tray further includes a drainer 23, which is disposed in the second water receiving tray 2 and fits the bottom of the second water receiving tray 2. By moving the drainer 23, liquids such as condensed water can be pushed into the water outlet 22 to improve drainage efficiency; at the same time, solid impurities can also be regularly pushed into the water outlet 22 through the drainer 23 for discharge and cleaning, thereby preventing solid impurities from clogging the water outlet 22 and affecting subsequent drainage operations.

[0051] Further, the drainer 23 includes a drain plate 231, a connecting protrusion 232 and a driving member. The drain plate 231 is fitted with the bottom of the second water receiving tray 2. The connecting protrusion 232 connects the drain plate 231 and the outer baffle 12. The outer baffle 12 is provided with a sliding guide rail 121 corresponding to the connecting protrusion 232. The driving member (not shown in the figure) is connected to the connecting protrusion 232 and is used to drive the connecting protrusion 232 to move in the sliding guide rail 121. The driving member is electrically connected to the liquid level sensor 14. When the liquid level sensor 14 senses that the water level in the second water receiving tray 2 reaches a certain value, it can be electrically connected to the driving member to drive the connecting protrusion 232 to move along the sliding guide rail 121, thereby driving the drain plate 231 to move along the sliding guide rail 121, and pushing the liquid and solid impurities in the second water receiving tray 2 to move. The setting of the connecting protrusion 232 and the sliding guide rail 121 facilitates the movement of the drain plate 231 along the sliding guide rail 121. Specifically, the drain plate 231 and the connection protrusion 232 are connected via a fixing member 2321 , and the fixing member 2321 may be a bolt, a screw, or the like.

[0052] In some embodiments, the double-layer water receiving tray also includes a high liquid level float switch 15, which is disposed in the second water receiving tray 2 and is connected to the water pump; or, the double-layer water receiving tray also includes a low liquid level float switch 16, which is disposed in the second water receiving tray 2 and is connected to the water pump.

[0053] Specifically, the high liquid level float switch 15 and the low liquid level float switch 16 are fixedly connected to the outer baffle 12, and are located in the second water receiving tray 2. They can be set close to the water outlet 22 to facilitate the monitoring and control of the water level; there is a height difference between the high liquid level float switch 15 and the low liquid level float switch 16, and there is a gap between the side and bottom of the second water receiving tray 2, so as to achieve accurate reading of the water level; the high liquid level float switch 15 and the low liquid level float switch 16 can send a switch signal to control the opening and closing of the water pump, thereby achieving the purpose of adjusting the liquid level.

[0054] The drainer 23 is preferably arranged between the high liquid level float switch 15 and the water outlet 22, and between the low liquid level float switch 16 and the water outlet 22, so as to prevent the drainer 23 from contacting or colliding with the high liquid level float switch 15 and the low liquid level float switch 16 during movement, thereby causing damage to the high liquid level float switch 15 and the low liquid level float switch 16; preferably, the height of the drain plate 231 is lower than the height of the high liquid level float switch 15 and the low liquid level float switch 16, so that the movement path of the high liquid level float switch 15 and the low liquid level float switch 16 does not overlap with the drain plate 231, thereby preventing the drain plate 231 from contacting or colliding with the high liquid level float switch 15 and the low liquid level float switch 16.

[0055] The double-layer water receiving tray may also include an external controller, which is electrically connected to the liquid level sensor 14, the high liquid level float switch 15, the low liquid level float switch 16, and the driving parts of the water pump, the lifter 6, and the drainer 23. The external controller can integrate the electrical signals transmitted by the liquid level sensor 14, the high liquid level float switch 15, and the low liquid level float switch 16, thereby controlling the movement of the driving parts of the water pump, the lifter 6, and the drainer 23, so as to understand the overall state of the double-layer water receiving tray and adjust the liquid level of the double-layer water receiving tray. Among them, the driving mode of the driving part can be common pneumatic drive, motor drive, etc.

[0056] Specifically, an evaporator is placed on the double-layer water receiving tray to receive condensed water and other liquids left by the evaporator; the liquid flows into the water outlet 22 of the second water receiving tray 2 through the evaporator support 11 and the first water receiving tray body 1 from the water inlet 21, and then flows out through the drain pipe 3. During this process, if the discharge efficiency of the drain pipe 3 is low, the liquid will accumulate in the second water receiving tray 2, causing the water level of the second water receiving tray 2 to rise, and the liquid level sensor 14 will sense the water level change of the second water receiving tray 2 and send it to the external controller. The external controller can adjust the opening and closing of the water pump and the power change according to the switch signal, thereby adjusting the discharge efficiency of the drain pipe 3; when the water level rises to the liquid level line of the low liquid level float switch 16, the low liquid level float switch 16 will send a switch signal to the external controller, and the external controller can adjust the opening and closing of the water pump and the power change according to the switch signal; when the water level rises to the liquid level line of the high liquid level float switch 15, the high liquid level float switch 15 will send a switch signal to the external controller, and the external controller can adjust the opening and closing of the water pump and the power change according to the switch signal.

[0057] At the same time, the external controller can also adjust the angle between the first water receiving tray main body 1 and the horizontal plane by driving the driving member of the lifter 6, thereby adjusting the drainage efficiency, or drive the driving member of the drainer 23 to promote the movement of liquid in the second water receiving tray 2, thereby adjusting the drainage efficiency; in addition, the external controller can also set parameters to control the driving frequency of the driving member of the drainer 23, thereby ensuring that solid impurities in the second water receiving tray 2 can be discharged in time to prevent the water outlet 22 from being blocked.

[0058] Combined with reference Figure 8 In the second embodiment of the present application, an air-conditioning device is provided, and the double-layer water receiving tray described in the first embodiment and its implementation method is used to receive condensed water, leaked liquid, etc. in other air-conditioning components.

[0059] The air conditioning device may further include a blower 5, and the double-layer water receiving tray is located below the blower 5. The height difference between the double-layer water receiving tray and the blower 5 can be set according to actual needs, and is set below the blower 5, that is, there is a height difference between the first water receiving tray body 1 and the second water receiving tray 2 and the blower 5, to prevent the airflow caused by the blower 5 from blowing up the liquid in the double-layer water receiving tray and causing liquid floating when the blower 5 is working. The second water receiving tray 2 is arranged close to the air supply port of the blower 5, which is conducive to the condensed water in the first water receiving tray body 1 flowing smoothly to the second water receiving tray 2 under the action of the airflow caused by the blower 5.

[0060] The first water receiving tray body 1 of the double-layer water receiving tray also includes an abutment 13 for abutting against the blower 5. The double-layer water receiving tray is connected to the blower 5 through the abutment 13 to improve the connection stability between the two. Specifically, one end of the abutment 13 is connected to the outer baffle 12, and the other end is connected to the blower 5. The connection method between the abutment 13 and the blower 5 can be a snap connection, a magnetic connection or a bolt connection.

[0061] Among them, in order to fix the position of the air supply fan 5, the air conditioning equipment also includes a fan mounting plate 51, and the air supply fan 5 is arranged on the fan mounting plate 51; the air supply fan 5 includes an air guide port, and the fan mounting plate 51 is provided with a fan air guide ring 52 corresponding to the air guide port of the air supply fan 5, so as to guide the airflow from the air guide port into the air supply fan 5, thereby improving the working efficiency of the air supply fan 5.

[0062] The air conditioning device also includes an evaporator (not shown in the figure), and the evaporator is arranged corresponding to the air guide port of the blower 5, so that the cold air treated by the evaporator is introduced into the blower 5 through the air guide port, and then sent into the room or the machine room by the blower 5, so as to achieve the effect of reducing the temperature in the room or the machine room. Specifically, the double-layer water receiving tray is located below the evaporator, and the evaporator is placed on the evaporator support 11; the evaporator support 11 can be provided with a protrusion that engages with the evaporator limit, and the connection stability between the evaporator support 11 and the evaporator can also be improved by bolt connection, magnetic connection, etc.

[0063] In summary, the present application provides a double-layer water receiving pan and air-conditioning equipment, wherein the double-layer water receiving pan comprises a first water receiving pan body and a second water receiving pan, and liquid can flow into the second water receiving pan from a water holding cavity formed by the first water receiving pan body and an outer baffle, and then be discharged through a drain pipe; the double-layer water receiving pan can be arranged at the bottom of the evaporator and the blower of the air-conditioning unit, and is used to discharge condensed water of the air-conditioning unit; the second water receiving pan is located below the first water receiving pan body and can be arranged with a height difference so that the amount of water accumulated in the first water receiving pan body is small and the liquid level is low, so that the water storage capacity of the double-layer water receiving pan can be increased, and the damage to the components caused by the contact of the accumulated water with the air-conditioning components due to excessive water accumulation in the double-layer water receiving pan is prevented, and the risk of floating and leakage caused by the reduction of the height difference between the accumulated water surface and the blower is reduced; at the same time, the water level of the accumulated water in the double-layer water receiving pan can be measured by a liquid level sensor, and the working power of the water pump can be started or increased after the accumulated water height reaches a certain value, so that the accumulated water can be quickly discharged from the drain pipe, the drainage efficiency is improved, and leakage is prevented.

[0064] The air conditioning equipment of the present application includes a double-layer water receiving pan, which can receive condensed water and leaked liquid from other air conditioning components through the double-layer water receiving pan and discharge it in time, thereby reducing the corrosion of condensed water and leaked liquid to the materials of other air conditioning components and reducing the risk of floating liquid and leaking liquid.
