Description

Technical Field

[0001] This utility model relates to the field of water tank technology, specifically a refrigeration water tank for refrigeration and air conditioning equipment. Background Technology

[0002] The building envelope of a refrigeration and air conditioning unit also transmits heat during use. Therefore, in order to maintain the low temperature conditions in the refrigeration and air conditioning unit, a refrigeration unit must be installed to continuously remove this heat. When the cooling water tank of the refrigeration and air conditioning unit cools the circulating water, an exhaust vent is needed to expel air in order to speed up the filling of water into the tank.

[0003] Chinese patent document CN218296175U discloses a cooling water tank for refrigeration and air conditioning equipment, including a water tank body. A water inlet pipe is fixedly installed on the left side of the water tank body and communicates with the interior of the water tank body. A water outlet pipe is fixedly installed on the lower end of the water tank body and communicates with the interior of the water tank body. A pressure cap is sealed and fixedly installed on the upper end of the water tank body. A fixing sleeve is fixedly installed in the middle of the pressure cap. The fixing sleeve is an I-shaped round sleeve with a circular hole vertically penetrating through the middle of the upper end of the fixing sleeve.

[0004] Although the aforementioned device can adjust the water circulation time of the floating block, the hole connecting to the outside air will be blocked when the floating block is still a certain distance from the top, resulting in a large amount of air inside the device, which reduces the water storage capacity. Furthermore, the opening status of the water outlet pipe is unclear, and it cannot automatically open after the water volume reaches the required level, indicating low automation under different conditions.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 This utility model provides a technical solution for a cooling water tank for refrigeration and air conditioning equipment: A cooling water tank for refrigeration and air conditioning equipment includes a device body 1, and a floating switch component 2 is provided inside the device body 1. The upper and lower ends of the floating switch component 2 extend to the outer sides of the upper and lower ends of the device body 1. The floating switch component 2 can monitor the water level of the circulating water in the device body 1 in real time and automatically discharge it after refrigeration.

[0025] Please see Figure 1 The main body of the device 1 includes a water tank container 12. A water tank cover 11 is provided at the top of the water tank container 12. Two opposing arc-shaped vents are opened vertically through the middle of the water tank cover 11. A water inlet is provided on the outer side of the outer surface of the water tank container 12, and a water outlet is provided in the middle of the bottom of the inner side of the water tank container 12. The side water inlet allows the incoming water to enter the water tank container 12 with an impact force. The vents provide a channel for the air inside the water tank container 12 to be discharged, and the inside of the water tank container 12 can be cleaned by opening the water tank cover 11.

[0026] Please see Figure 2 The water tank container 12 includes a water tank shell 123. The top of the water tank shell 123 is tightly attached to the bottom of the water tank cover plate 11. A water guide plate 122 is fixedly connected to the bottom of the inner side of the water tank shell 123. The water guide plate 122 can guide the incoming circulating water to move in a regular manner. A water inlet pipe 121 is fixedly connected inside the water inlet. A one-way valve is fixedly connected inside the water inlet pipe 121 to prevent the internal circulating water from flowing back.

[0027] Please see Figure 2 The water guide plate 122 is spiral-shaped. The outermost end of the water guide plate 122 is in close contact with the inner side of the water tank shell 123 where it intersects with the water inlet. The end of the water guide plate 122 near the middle of the water tank shell 123 is in close contact with the outer surface of the floating switch component 2.

[0028] The spiral water guide plate 122 guides the incoming circulating water to move in a spiral motion while maintaining a certain impact force. The water flow at the bottom drives the circulating water above to rotate and stir, so that the cooling effect can be more uniform through its own stirring, thereby improving the cooling effect.

[0029] Please see Figure 3The floating switch component 2 includes a connecting post 22. Two parallel moving grooves are opened on the outer surface of the connecting post 22. A floating component 21 is slidably connected to the outer surface of the connecting post 22 and the floating component 21 slides in the moving grooves. A water outlet component 24 is slidably connected to the bottom end of the connecting post 22. Filter screens 23 are slidably connected to both the left and right sides of the water outlet component 24. A drain outlet is opened through the bottom end of the connecting post 22. The top outer surface of the floating component 21 is slidably connected to the middle of the water tank cover plate 11. The connecting post 22 can slide slightly inside the water tank cover plate 11.

[0030] The floating component 21 can monitor the water level through the buoyancy provided by the circulating water. Then, when it slides to the top of the moving tank, the buoyancy will drive the connecting column 22 to slide upward. The connecting column 22 will then drive the water outlet component 24 to snap open the drain outlet, and water will be discharged through the outlet. During the water discharge process, the circulating water is filtered by the filter screen 23, and the filter screen 23 can be removed for cleaning.

[0031] Please see Figure 4 The floating component 21 includes a buoyancy wheel 211. Two air-sealing ribs 212 are fixedly connected to the top of the buoyancy wheel 211. The air-sealing ribs 212 are raised by the buoyancy wheel 211 to block the air vent. Two moving slots at the bottom of the buoyancy wheel 211 are fixedly connected to corresponding positions of a closing block 213. The bottom of the closing block 213 is opened into an inclined surface near the outer corner of the connecting column 22. The middle part of the buoyancy wheel 211 is slidably connected to the outer surface of the connecting column 22, so that the buoyancy wheel 211 can slide up and down on the surface of the connecting column 22.

[0032] Please see Figure 4 The air-sealing rib 212 is spirally ascending. The lowest and highest points of the two closed blocks 213 are adjacent, and the two air-sealing ribs 212 are connected by a connecting column 22. The air-sealing rib 212 can block the air vent through the vent. During the process of the buoyancy wheel 211 lifting the air vent, the higher end will be blocked first and move upward. During the upward movement, the space of the air vent will be gradually reduced, and the speed of circulating water injection will be reduced. After the water injection volume reaches the standard, the air-sealing rib 212 will just completely block the air vent, so that water injection at the water inlet pipe 121 will stop.

[0033] Please see Figure 5 The water outlet assembly 24 includes two sliding blocks 241, which are fixedly connected to the bottom of the moving groove. A support spring 242 is fixedly connected to the end of the sliding block 241 away from the connecting column 22. A fixing block 243 is fixedly connected to the end of the support spring 242 away from the sliding block 241. The top of the fixing block 243 is opened at the outer angle away from the support spring 242 as a slope. The bottom ends of the two fixing blocks 243 are closely attached to the water outlet pipe 245. The lower side of the outer surface of the water outlet pipe 245 is fixedly connected to the inner side of the water outlet. The water outlet pipe 245 has a gap opening running through it from front to back. Fixing grooves are opened on the upper left and right sides inside the gap opening. A filter screen 23 is movably connected to the front and back of the fixing groove.

[0034] As the floating component 21 rises to the top, it drives the connecting column 22 to move upward, causing the fixed block 243 to move upward through the inclined plane, pass through the water outlet pipe 245, and be supported by the support spring 242 to unfold its bottom surface and contact the top of the water outlet pipe 245 to prevent the drain outlet from falling and close the drainage channel. The circulating water enters the drain outlet after passing through the filter screen 23 set in the gap and is discharged from the inside of the water outlet pipe 245 for circulation. After the water is discharged, the buoyancy wheel 211 descends to the top of the sliding block 241 according to the horizontal plane. The closing block 213 squeezes and contracts the fixed block 243, allowing the lower part of the connecting column 22 to move downward by gravity, so that the drain outlet is tightly covered with the inside of the water outlet pipe 245, closing the drain outlet and starting the next water storage.

[0035] Working principle:

[0036] First, water is injected through the inlet pipe 121. The circulating water is guided by the guide plate 122 to make the water flow spiral and drive the water above to be spirally stirred. At the same time, the buoyancy wheel 211 moves upward by the buoyancy of the circulating water until the air vent 212 gradually blocks the air vent. While blocking, the air vent is reduced, which slows down the water injection speed. When it is completely blocked, the water injection stops. At the same time, the connecting column 22 moves upward a distance, so that the fixing block 243 extends above the outlet pipe 245 by the pulling force, and while exposing the drain outlet, it jams the outlet pipe 245, so that the water is discharged through the filter screen 23 and the outlet pipe 245. After the circulating water is discharged, the buoyancy wheel 211 falls back, which drives the closing block 213 to squeeze the fixing block 243, so that the connecting column 22 descends and closes the drain outlet.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
