[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1 , shows one of the structural schematic diagrams of an air conditioning water injection system provided in an embodiment of the present invention. The air conditioning water injection system comprises an air conditioning body 1, a water injection tank 4, a vertical rod 3, a pressure spring 10, a distance sensor 17 and a water adding mechanism. The air conditioning body 1 is provided with a water tray 2, an installation port 12 (refer to Figure 2 ) and the mounting plate 14 corresponding to the mounting opening 12 (refer to Figure 3 ), a stop plate 9 is provided at one end of the vertical rod 3 near the end surface, and at least one water leakage hole 16 is provided at the bottom of the water injection box 4 (refer to Figure 4 ).

[0033] Among them, the installation port 12 of the air-conditioning body 1 is connected to the inner cavity of the water tray 2, and one end of the vertical rod 3 is provided with a limit plate 9 connected to the center of the inner cavity of the water tray 2, that is, one end of the vertical rod 3 is provided with a limit plate 9 connected to the center of the bottom surface of the inner cavity of the water tray 2, and the vertical rod 3 is perpendicular to the bottom surface of the inner cavity of the water tray 2, a part of the water filling tank 4 is located in the installation port 12 of the air-conditioning body 1, and the other part is located in the inner cavity of the water tray 2, the pressure spring 10 is sleeved on the vertical rod 3, one end is connected to the limit plate 9, and the other end is connected to the bottom of the water filling tank 4, the distance measuring sensor 17 is provided at the top of the water filling tank 4, the distance measuring sensor 17 is used to measure the distance between the top of the water filling tank 4 and the mounting plate 14, the water adding mechanism is connected to the water filling tank 4, and the water adding mechanism is used to add water to the water filling tank 4 based on the distance between the top of the water filling tank 4 and the mounting plate 14.

[0034] Specifically, when the water filling box 4 is assembled in the mounting port 12 and the inner cavity of the water tray 2, the mounting port 12 is covered with the mounting plate 14, and an upward force is given to the water filling box 4 through the pressure spring 10 sleeved on the vertical rod 3 to support the water filling box 4, and the pressure spring 10 is always in a compressed state.

[0035] The bottom of the water filling tank 4 is located in the inner cavity of the water pan 2. When the air conditioner is running, the water in the inner cavity of the water pan 2 is consumed to a position lower than the leakage hole 16 of the water filling tank 4, and the water in the water filling tank 4 will flow into the inner cavity of the water pan 2 through the leakage hole 16. As the water in the water filling tank 4 decreases, the weight of the water filling tank 4 decreases, and the pressure spring 10 releases its elastic potential energy. The water filling tank 4 is raised by the force of the pressure spring 10. At this time, the distance between the top of the water filling tank 4 and the mounting plate 14 measured by the ranging sensor 17 gradually shortens. Therefore, the water adding mechanism can be controlled to work based on the distance between the top of the water filling tank 4 and the mounting plate 14 to add water to the water filling tank 4, thereby realizing automatic water filling of the water filling tank 4 and automatic water replenishment to the inner cavity of the water pan 2.

[0036] When the water filling tank 4 is being filled with water, the water level lines in the inner cavity of the water tray 2 and the water filling tank 4 will rise, the weight of the water filling tank 4 will increase, the pressure spring 10 will be compressed, and the position of the water filling tank 4 will continue to decrease until the water adding mechanism stops adding water.

[0037] In the embodiment of the present invention, during the operation of the air conditioner, when the water in the inner cavity of the water pan 2 is consumed to a position lower than the leakage hole 16 of the water filling tank 4, the water in the water filling tank 4 will flow into the inner cavity of the water pan 2 through the leakage hole 16, and as the water in the water filling tank 4 decreases, the weight of the water filling tank 4 decreases, the pressure spring 10 releases elastic potential energy, and the water filling tank 4 is raised by the force of the pressure spring 10. The distance between the top of the water filling tank 4 and the mounting plate 14 measured by the ranging sensor 17 gradually shortens. Therefore, the water adding mechanism can be controlled to work based on the distance between the top of the water filling tank 4 and the mounting plate 14 to add water to the water filling tank 4, thereby realizing automatic water filling of the water filling tank 4 to realize automatic water replenishment to the inner cavity of the water pan 2. There is no need to manually open the mounting plate 14 for water adding operation, which saves human resources, improves work efficiency, and solves the problem that the air conditioning water adding operation is cumbersome and it is easy to occur that the low water volume cannot be discovered in time, resulting in the occurrence of situations that affect the operation of the air conditioner.

[0038] In addition, in the embodiment of the present invention, only one distance measuring sensor 17 is used to realize automatic water filling of the water filling box 4 to realize automatic water replenishment into the inner cavity of the water tray 2. The overall components are less and the corresponding volume is also reduced, which can effectively save costs.

[0039] Based on the above embodiment, a variant embodiment of the above embodiment is proposed. It should be noted that in order to make the description concise, only the differences from the above embodiment are described in the variant embodiment.

[0040] In an exemplary embodiment, when the water filling tank 4 is raised to the point where the distance between the top of the water filling tank 4 and the mounting plate 14 is less than a first preset distance, it indicates that the amount of water in the water filling tank 4 is insufficient. Therefore, when the distance sensor detects that the distance between the top of the water filling tank 4 and the mounting plate 14 is less than the first preset distance, the water adding mechanism is triggered to work, and water is added to the water filling tank 4 through the water adding mechanism.

[0041] During the process of the water adding mechanism adding water to the water filling tank 4, the weight of the water filling tank 4 increases, the pressure spring 10 begins to compress, and the position of the water filling tank 4 rises until the distance between the top of the water filling tank 4 and the mounting plate 14 is greater than the second preset distance, indicating that the water in the water filling tank 4 and the water tray 2 is sufficient at this time. Therefore, when the distance sensor detects that the distance between the top of the water filling tank 4 and the mounting plate 14 is greater than the second preset distance, the water adding mechanism is triggered to stop working and stop adding water to the water filling tank 4. Among them, the first preset distance is less than the second preset distance, and the values ​​of the first preset distance and the second preset distance can be specifically set according to actual conditions, and the embodiment of the present invention is not limited to this.

[0042] It should be noted that after the water adding mechanism is triggered to work, water is added to the water filling tank 4 through the water adding mechanism. Since the position of the water filling tank 4 will immediately drop a part, the distance between the top of the water filling tank 4 and the mounting plate 14 will be greater than the first preset distance. Therefore, setting the distance between the top of the water filling tank 4 and the mounting plate 14 to be greater than the first preset distance will not trigger the water adding mechanism to stop working, so as to avoid the water adding mechanism from frequently starting and stopping work.

[0043] In the above embodiment, when the distance between the top of the water filling tank 4 and the mounting plate 14 is less than the first preset distance, the water adding mechanism adds water to the water filling tank 4, and when the distance between the top of the water filling tank 4 and the mounting plate 14 is greater than the second preset distance, the water adding mechanism stops adding water to the water filling tank 4, thereby realizing automatic water filling of the water filling tank 4 to realize automatic water replenishment into the inner cavity of the water tray 2, without the need to manually open the mounting plate 14 to perform water adding operations, saving human resources, improving work efficiency, and solving the problem that the air conditioning water adding operation is cumbersome and it is easy to have problems such as failure to timely detect low water volume, which affects the operation of the air conditioner.

[0044] In an exemplary embodiment, the water adding mechanism may include a control unit, a water pipe 18 and a water pump 19 disposed on the water pipe 18; the tops of the mounting plate 14 and the water filling tank 4 are both provided with water pipe holes.

[0045] Among them, the control unit is electrically connected to the water pump 19 and the ranging sensor 17 respectively, one end of the water pipe 18 is connected to a water source, which can be a water tank, a pool, etc., the other end of the water pipe 18 passes through the water pipe hole on the top of the mounting plate 14 and the water filling tank 4 and is located in the water filling tank 4, and the other end of the water pipe 18 slides with the water pipe hole on the top of the water filling tank 4.

[0046] Specifically, as the amount of water in the water injection tank 4 increases or decreases, the water injection tank 4 will float up and down along the water pipe 18. When the distance between the top of the water injection tank 4 and the mounting plate 14 is less than the first preset distance, the control unit will receive the first signal sent by the distance measuring sensor 17, and the control unit will control the water pump 19 to start working based on the first signal, and transport the water in the water storage tank and the pool to the water injection tank 4 through the water pipe 18, thereby realizing automatic water filling of the water injection tank 4, and then realizing automatic water replenishment of the water tray 2 by the water injection tank 4.

[0047] After the water adding mechanism adds water to the water filling tank 4, when the distance between the top of the water filling tank 4 and the mounting plate 14 is greater than the second preset distance, the control unit will receive a second signal sent by the distance measuring sensor 17, and the control unit will control the water pump 19 to stop working based on the second signal and stop adding water to the water filling tank 4.

[0048] In the above embodiment, the water filling tank 4 can be automatically filled with water through the distance sensor 17, the control unit, the water pipe 18 and the distance sensor 17, so that the inner cavity of the water tray 2 is automatically replenished with water without manually opening the mounting plate 14 to add water, thereby saving human resources and improving work efficiency.

[0049] In an exemplary embodiment, the water adding mechanism may further include a control unit, a water pipe 18 and a solenoid valve disposed on the water pipe 18 , and water pipe holes are disposed on the top of the mounting plate 14 and the water filling box 4 .

[0050] Among them, the control unit is electrically connected to the solenoid valve and the distance measuring sensor 17 respectively, one end of the water pipe 18 is connected to the tap water, and the other end passes through the mounting plate 14 and the water pipe hole at the top of the water filling box 4 and is located in the water filling box 4, and the other end of the water pipe 18 slides with the water pipe hole at the top of the water filling box 4.

[0051] Specifically, as the amount of water in the water injection tank 4 increases or decreases, the water injection tank 4 will float up and down along the water pipe 18. When the distance between the top of the water injection tank 4 and the mounting plate 14 is less than the first preset distance, the control unit will receive the first signal sent by the distance measuring sensor 17, and the control unit will control the solenoid valve to open based on the first signal, and the water in the tap water will be transported to the water injection tank 4 through the water pipe 18, thereby realizing automatic water injection to the water injection tank 4, and then realizing automatic water replenishment of the water tray 2 by the water injection tank 4.

[0052] After the water adding mechanism adds water to the water filling tank 4, when the distance between the top of the water filling tank 4 and the mounting plate 14 is greater than the second preset distance, the control unit will receive a second signal sent by the distance measuring sensor 17, and the control unit will open the solenoid valve based on the second signal to stop adding water to the water filling tank 4.

[0053] In the above embodiment, the water filling tank 4 can be automatically filled with water through the distance sensor 17, the solenoid valve, the water pipe 18 and the distance sensor 17, thereby realizing automatic water replenishment into the inner cavity of the water tray 2, without the need to manually open the mounting plate 14 to perform water adding operations, thereby saving human resources and improving work efficiency.

[0054] In an exemplary embodiment, a filter screen 13 is provided in the water filling tank 4, and the filter screen 13 is used to filter the water added to the water filling tank 4 by the water adding mechanism. For example, the filter screen 13 can be arranged below the water outlet of the water pipe 18, so as to filter the water added to the water filling tank 4 by the water adding mechanism and ensure the cleanliness of the water in the water filling tank 4.

[0055] In an exemplary embodiment, a filter screen 13 or a filter may be directly provided in the water pipe 18 to filter the water added to the water filling tank 4 by the water adding mechanism, thereby ensuring the cleanliness of the water in the water filling tank 4.

[0056] Reference Figure 5 , shows a schematic diagram of the internal structure of a water injection box provided by an embodiment of the present invention. The bottom of the water injection box 4 is provided with a limit tube 11 which is convex upward to form a hollow and bottom open, and the top of the limit tube 11 is provided with a vertical rod hole.

[0057] Among them, the vertical rod 3 and at least a part of the pressure spring 10 are accommodated in the limiting cylinder 11, one end of the pressure spring 10 is connected to the limiting plate 9 on the vertical rod 3, and the other end is connected to the top of the limiting cylinder 11, and the end of the vertical rod 3 away from the limiting plate 9 passes through the vertical rod hole and is located in the water filling tank 4, and the end of the vertical rod 3 away from the limiting plate 9 is slidably matched with the vertical rod hole, and the connection between the end of the vertical rod 3 away from the limiting plate 9 and the vertical rod hole is in a sealed state, thereby preventing water in the water filling tank 4 from flowing into the inner cavity of the water tray 2 from the vertical rod hole.

[0058] Specifically, when the water level in the water pan 2 is lower than the water leakage hole 16 in the water filling tank 4, the water in the water filling tank 4 will flow into the inner cavity of the water pan 2 through the water leakage hole 16, the amount of water in the water filling tank 4 will decrease, the weight of the water filling tank 4 will decrease, and the force of the pressure spring 10 will cause the water filling tank 4 to slide upward along the vertical rod 3. When the water adding mechanism adds water to the water filling tank 4, the amount of water in the water filling tank 4 will increase, the weight of the water filling tank 4 will increase, the pressure spring 10 will be compressed, and the water filling tank 4 will slide downward along the vertical rod 3.

[0059] In the above embodiment, when the amount of water in the water filling tank 4 changes, the water filling tank 4 can float up and down along the vertical rod 3 by the force of the spring, thereby realizing automatic water filling of the water filling tank 4, and then realizing automatic water replenishment into the inner cavity of the water tray 2. There is no need to manually open the mounting plate 14 to add water, thereby saving human resources and improving work efficiency.

[0060] It should be noted that the setting method of the limiting cylinder 11 and the vertical rod 3 can adopt other methods besides the above-mentioned method, and the invention is not limited to this. For example, the bottom of the water filling tank 4 can be provided with a limiting cylinder 11 that is convex upward to form a hollow and bottom-open. The vertical rod 3 and at least a part of the pressure spring 10 are accommodated in the limiting cylinder 11, one end of the pressure spring 10 is connected to the limiting plate 9 on the vertical rod 3, and the other end is connected to the top of the limiting cylinder 11. When the water filling tank 4 is filled with water, the compressed length of the pressure spring 10 is greater than or equal to the length between the end face of the end of the vertical rod 3 that is away from the limiting plate 9 and the limiting plate 9. When the water filling tank 4 floats up and down due to the increase or decrease of the internal water volume, the top of the limiting cylinder 11 will not touch the end of the vertical rod 3 that is away from the limiting plate 9.

[0061] Reference Figure 6 , showing a method provided in an embodiment of the present invention Figure 2 The inner side of the installation opening 12 is provided with a movable slot 6, and the bottom of the movable slot 6 is provided with a spring hole 7, which is used to install an auxiliary spring 8. The outer side of the water filling box 4 is provided with a strap 5 adapted to the movable slot 6 (refer to Figure 4 ).

[0062] The number of the straps 5 , the movable slots 6 and the auxiliary springs 8 of the water filling box 4 is at least two, and the straps 5 , the movable slots 6 and the auxiliary springs 8 of the water filling box 4 are evenly distributed along the circumference of the water filling box 4 .

[0063] When the water filling tank 4 is located in the installation port 12 and the inner cavity of the water tray 2, at least a portion of the bridge plate 5 of the water filling tank 4 is located in the movable slot 6 and above the auxiliary spring 8. When the amount of water in the water filling tank 4 increases or decreases, the weight of the water filling tank 4 will also increase or decrease accordingly. At this time, the auxiliary spring 8 will lift the water filling tank 4 together with the pressure spring 10, and compress or expand together, so that the water filling tank 4 floats up and down with the amount of water inside.

[0064] In the above embodiment, the water filling box 4 can be lifted up by the auxiliary spring 8 together with the pressure spring 10, and compressed or expanded based on the water amount inside the water filling box 4, so that the water filling box 4 floats up and down with the water amount inside, and at least two auxiliary springs 8 evenly distributed along the circumference of the water filling box 4 make the water filling box 4 move up more smoothly.

[0065] Refer again Figure 3A limit block 15 protruding toward the movable slot 6 is provided at a position corresponding to the mounting plate 14 and the movable slot 6. The limit block 15 is used to limit the upward movement of the bridge plate 5 of the water filling box 4, and the limit block 15 maintains a certain distance from the bottom of the movable slot 6.

[0066] When the water filling box 4 moves upward, the bridge plate 5 of the water filling box 4 will contact the limit block 15, so that the water filling box 4 is restricted from continuing to rise by the limit block 15, so as to avoid the bridge plate 5 driving the water filling box 4 to move upward too much and causing the water filling box 4 to be unstable.

[0067] It should be noted that the mounting plate 14 and the limit block 15 can be integrated or can be two separate structures. When needed, the mounting plate 14 and the limit block 15 can be assembled together for use. Therefore, the embodiment of the present invention does not limit the structure of the mounting plate 14 and the limit block 15.

[0068] In an exemplary embodiment, the top of the water filling box 4 may be a detachably mounted cover plate 20 to facilitate the installation of the water pipe 18 and the filter screen 13 and the cleaning of the filter screen 13 .

When the water filling tank 4 moves toward the mounting plate 14 and the detection value of the distance sensor 17 is less than the first preset distance, the control unit can control the water pump 19 to inject water into the water filling tank 4 until the detection value of the distance sensor 17 is greater than the second preset distance, and the water injection is stopped; the water pump 19 is started by controlling the distance sensor 17, and the water pump 19 is connected to the water tank storing water, which can facilitate the water pump 19 to absorb water.

[0071] The width of the movable slot 6 matches the width of the strap 5. One end of the strap 5 is located inside the movable slot 6. The strap 5 can press the auxiliary spring 8 inside the movable slot 6 to contract. When the amount of water inside the water filling box 4 is large, the auxiliary spring 8 contracts more. Similarly, when the amount of water is small, the auxiliary spring 8 can gradually lift the water filling box 4.

[0072] A limiting cylinder 11 is arranged inside the water filling box 4, the vertical rod 3 passes through the limiting cylinder 11, the pressure spring 10 is located inside the limiting cylinder 11, and one end of the pressure spring 10 is fixedly connected to the inner upper part of the limiting cylinder 11. The water filling box 4 can drive the pressure spring 10 to contract through the limiting cylinder 11.

[0073] A mounting plate 14 is provided on the upper part of the mounting opening 12, and a limit block 15 is fixedly installed on the side of the mounting plate 14. When the water filling box 4 rises, it can drive the strap plate 5 to rise. When the strap plate 5 reaches the lower part of the limit block 15, the water filling box 4 cannot continue to rise. At this time, the amount of water inside the water filling box 4 is small and water needs to be added in time. A water pump 19 is fixedly installed on the mounting plate 14, and a water pipe 18 is provided on the water pump 19. The water pipe 18 passes through the mounting plate 14 and the sealing plate 20 and extends to the inside of the water filling box 4. The water pipe 18 slides with the water pipe hole on the mounting plate 14; the water pump 19 is connected to the water tank for storing water, which can facilitate the water pump 19 to absorb water. This structure is a prior art and will not be described in detail here. Then the water pump 19 injects water into the water filling box 4 through the water pipe 18.

[0074] The size of the limit block 15 matches the size of the movable slot 6. The limit block 15 is located at the upper part of the movable slot 6, and can limit the take-up plate 5. When the take-up plate 5 rises to the lower part of the limit block 15, the water filling tank 4 cannot continue to rise. At this time, the amount of water inside the water filling tank 4 is relatively small. The limit block 15 can prevent the take-up plate 5 from driving the water filling tank 4 to move up too much, causing the water filling tank 4 to be unstable.

[0075] A filter screen 13 is provided inside the water injection tank 4 to filter the water injected by the water pump 19 to ensure the cleanliness of the water in the water injection tank 4 .

[0076] Among them, the number of the bridge plate 5 and the auxiliary spring 8 is two, and the auxiliary spring 8 can shrink according to the amount of water inside the water filling box 4. When the water amount is small, the auxiliary spring 8 will cooperate with the pressure spring 10 to lift the water filling box 4. They are respectively located on both sides of the water filling box 4, which can make the water filling box 4 move up more smoothly.

[0077] The bottom surface of the water filling box 4 is lower than the upper end surface of the water tray 2.

[0078] Working principle: When this type of evaporative cooling air conditioning system for data centers is in use, water is first injected into the water tank 4 through the water pump 19 and the water pipe 18, and the injection of water is stopped until the detection value of the distance sensor 17 is greater than the second preset distance. The water flows into the water pan 2 through the leaking hole 16 at the bottom of the water tank 4. When the water level in the water pan 2 submerges the leaking hole 16, the water gradually accumulates inside the water tank 4, so that the water pan 2 and the water tank 4 maintain a high water level. The water tank 4 can press the auxiliary spring 8 and the pressure spring 10 to contract due to the large amount of water inside. When this type of evaporative cooling air conditioning system for data centers is in operation, when the amount of water in the water pan 2 gradually decreases and the water level is lower than the height of the leaking hole 16, the water flow inside the water tank 4 will enter the water pan 2 through the leaking hole 16. At this time, the water tank 4 has less water inside and its weight is reduced. The force of the auxiliary spring 8 and the pressure spring 10 can lift the water tank 4. The higher the water tank 4 rises, the tighter the sealing plate 2 of the water tank 4 will be. 0 moves in the direction close to the mounting plate 14, the distance sensor 17 detects the distance between the sealing plate 20 and the mounting plate 14, when the water filling box 4 moves in the direction close to the mounting plate 14 and the detection value of the distance sensor 17 is less than the first preset distance, the control unit can control the water pump 19 to fill water into the water filling box 4, and stop filling water when the detection value of the distance sensor 17 is greater than the second preset distance, which not only realizes the automation of water filling, but also reduces the starting frequency of the water pump 19. When the amount of water in the water pan 2 is small, water can be filled into the water pan 2 through the water filling box 4, so that the air conditioner body 1 can continue to cool, thereby avoiding the problem that there is no water in the water pan 2 affecting the operation of the air conditioner; when adding water, water can be automatically filled from the upper part of the water filling box 4 without opening the mounting plate 14.
