Description

Technical Field

[0001] This utility model relates to the field of air cooler technology, and in particular to a chassis and an air cooler. Background Technology

[0002] An evaporative air cooler is a machine that cools an indoor space by exchanging heat between flowing air and a cooling medium. The evaporative air cooler uses a circulating water pump to continuously draw water from a tank and spray it evenly onto a paper curtain through a water distribution system. Hot outside air enters the evaporative air cooler through the paper curtain and fully exchanges heat with the water, creating cool air. This cool air is then pressurized by a fan and delivered into the room, ultimately exhausting the hot indoor air to the outside, achieving the purpose of cooling the room. In existing technology, when it is necessary to repair components such as the water pump or valve located in the evaporative air cooler's water tank, the operator needs to disassemble the entire machine to repair the internal parts, which takes a significant amount of time.

[0027] An evaporative air cooler is a machine that cools an indoor space by exchanging heat between flowing air and a cooling medium. The evaporative air cooler uses a circulating water pump to continuously draw water from a tank and spray it evenly onto a paper curtain through a water distribution system. Hot outside air enters the evaporative air cooler through the paper curtain and fully exchanges heat with the water, creating cool air. This cool air is then pressurized by a fan and delivered into the room, ultimately exhausting the hot indoor air to the outside, achieving the purpose of cooling the room. In existing technology, when it is necessary to repair components such as the water pump or valve located in the evaporative air cooler's water tank, the operator needs to disassemble the entire machine to repair the internal parts, which takes a significant amount of time.

[0028] Please see Figure 1-5 In one embodiment of the present invention, the chassis 100 includes: a bellows 1, a water tank 2, and a cover plate 3. The bellows 1 has a first chamber with an inlet and outlet 11 that opens towards the interior, allowing people to pass through. The first chamber is connected to the interior through the inlet and outlet 11. The water tank 2 has a second chamber with a connecting opening 21 that allows people to pass through. The first chamber and the second chamber are connected through the connecting opening 21. The cover plate 3 is used to open or close the connecting opening 21.

[0029] In this embodiment, the bellows 1 is used for airflow. Hot air enters the first chamber of the bellows 1, where heat exchange occurs, creating cool air. This cooled air is then blown out by the compressor and compressed air duct within the bellows 1, thus cooling the indoor air. The water tank 2 is used to hold liquid. The water tank 2 is divided into a cold water zone and a hot water zone. The water in the cold water zone is used to keep the paper curtain device 4 installed in the bellows 1 moist, ensuring a constant flow of cooling water on the paper curtain device 4. The water in the water tank 2 is sent to the top of the paper curtain device 4 via a power device, then flows naturally down the paper curtain and back into the water tank 2. The bellows 1 is located at the top of the overall casing 100, and the water tank 2 is located at the bottom of the overall casing 100, adjacent to and below the bellows 1. In this embodiment, the bellows 1 has an inlet and outlet 11 that opens towards the interior, allowing operators to enter the first chamber through the inlet and outlet 11. The water tank 2 is provided with a connecting port 21 above the first chamber of the bellows 1. The connecting port 21 can also be used by people. After entering the first chamber from the inlet and outlet 11, the operators can enter the second chamber through the connecting port 21 to perform maintenance on the mechanical equipment located in the second chamber.

[0030] Understandably, water tank 2 contains components such as water pumps and valves. These components provide power to circulate water, originally located at the bottom of casing 100, to other parts or equipment within casing 100 according to a preset method, thus achieving water circulation within the evaporative cooler. However, since the water pumps and valves operate continuously after the evaporative cooler is turned on until the machine is turned off, these components are more prone to failure due to fatigue than other components, requiring frequent maintenance. Since evaporative coolers are typically located outdoors, in existing technologies, operating or maintaining the equipment in water tank 2 requires moving outdoors and completely disassembling the casing 100 to expose the equipment in the second chamber at the bottom. This incurs significant time consumption for equipment in water tank 2 that requires frequent maintenance. This application provides a connection port 21 in the water tank 2 that connects to the first chamber, and the first chamber is provided with an entrance and exit that connects to the equipment. This allows the operator located inside the water tank 2 to directly enter the first chamber from inside the room through the entrance and exit when the equipment in the water tank 2 malfunctions. Then, the operator can enter the second chamber from the first chamber through the connection port 21 to repair or replace the equipment and parts in the water tank 2.

[0031] The technical solution of this utility model adopts a bellows 1 with a first chamber in the casing 100. The first chamber has an inlet and outlet 11 that opens to the interior and allows people to pass through, so that the operator can enter the first chamber of the bellows 1 from the interior through the inlet and outlet 11. It also adopts a water tank 2 with a connecting port 21. The connecting port 21 can be opened and closed by a cover plate 3. The second chamber of the water tank 2 can be connected to the first chamber through the connecting port 21. The operator can enter the second chamber from the first chamber through the connecting port 21. Thus, the operator can directly enter the water tank 2 of the air cooler located outdoors from the interior to perform maintenance on the internal structure of the water tank 2 without disassembling the casing 100, thereby improving the convenience of maintaining the internal structure of the water tank 2.

[0032] Please see Figure 1-3 In one embodiment, a partition 22 is provided on the side of the water tank 2 near the air box 1. The partition 22 is used to separate the first chamber and the second chamber. A connecting port 21 is opened on the partition 22, and a cover plate 3 is detachably connected to the partition 22. The partition 22 separates the water tank 2 and the air box 1, provides an installation position for the equipment located in the first chamber, and supports the components in the first chamber. The partition 22 also prevents water in the water tank 2 from evaporating into the first chamber, thus preventing damage to the components in the first chamber. The cover plate 3 is detachably installed on the partition 22 and can open or close the connecting port 21 as needed. When the connecting port 21 is open, the operator can enter the second chamber through the connecting port 21. When the air cooler is operating, the cover plate 3 closes the connecting port 21 to prevent water in the water tank 2 from evaporating into the first chamber and causing equipment failure in the first chamber.

[0033] Please see Figure 3 , 4 In one embodiment, the cover plate 3 includes a body 31, and a snap-fit ​​portion 32 and a connecting portion 33 disposed opposite to each other on both sides of the body 31. The cover plate 3 is detachably connected to the partition plate 22 through the connecting portion 33 and the snap-fit ​​portion 32. The snap-fit ​​portion 32 and the connecting portion 33 are disposed on opposite sides of the body 31, which can balance the forces on both sides of the cover plate 3, so that the cover plate 3 can be more stably installed on the body 31 and cover the communication opening 21.

[0034] In one embodiment, the partition 22 has a first side edge and a second side edge on opposite sides of the connecting port 21. The partition 22 is detachably connected to the snap-fit ​​part 32 via the first side edge, and the partition 22 is detachably connected to the connecting part 33 via the second side edge. The first side edge is used to connect with the snap-fit ​​part 32 to limit one side of the cover plate 3 to the first side edge, and the second side edge is used to connect with the connecting part 33 to limit the other side of the cover plate 3 to the second side edge, thereby fixing the cover plate 3 to the partition 22 from both sides of the cover plate 3.

[0035] In one embodiment, the latching portion 32 includes at least two latches 321 spaced apart along the outer edge of the body 31. A slot 221 is formed on the first side edge corresponding to the position of the latches 321 for engaging with the latches 321. The latches 321 elastically abut against the first side edge through the slot 221. The number of latches 321 can be increased or decreased according to factors such as the actual volume, mass, or stability requirements of the cover plate 3. The more latches 321 in the latching portion 32, the more stably the cover plate 3 can be installed in the partition 22. The slot 221 is used to limit the position of the latches 321 in the horizontal direction. The latches 321 and the first side edge abut against each other through the elasticity of the latches 321 themselves, so that the latches 321 continuously exert force on the first side edge, thereby restricting the latches 321 in the slot 221.

[0036] In one embodiment, the connecting portion 33 includes at least two protrusions 331 spaced apart along the outer edge of the body 31, and a slot 222 is provided on the second side edge for inserting the protrusions 331. The protrusions 331 are inserted into the second side edge through the slot 222. The number of protrusions 331 can be increased or decreased according to factors such as the actual volume, mass, or stability requirements of the cover plate 3. During installation, the protrusions 331 are first inserted one-to-one into the slot 222, and then the buckle 321 is snapped into the slot 221 to complete the fixation of the cover plate 3.

[0037] Please see Figure 4 , 5 In one embodiment, the buckle 321 has a first piece 321a and a second piece 321b connected to each other. The second piece 321b is elastically connected to the body 31 through the first piece 321a. A protrusion is provided on the side of the second piece 321b away from the body 31. A limiting block is provided at the end of the slot 221 near the air box 1. The limiting block can limit the protrusion in the slot 221. The first piece 321a and the second piece 321b are arranged sequentially along the edge of the cover plate 3 in an outward direction. The first piece 321a and the second piece 321b are folded together to form a V-shape or a U-shape. By changing the included angle between the first piece 321a and the second piece 321b by external force, the buckle 321 can have elasticity, thereby continuously abutting the second piece 321b against the first side edge. The limiting block is used to cooperate with the protrusion to limit the position of the first piece 321a in the height direction. The second piece 321b moves towards the body 31 under the action of external force, thereby reducing the included angle between the first piece 321a and the second piece 321b. The distance between the second piece 321b and the body 31 is shortened, allowing the protrusion to enter the limiting groove. Then, the external force applied to the second piece 321b is released, and the second piece 321b moves towards the first side edge under the action of elastic force, and finally abuts against the first side edge. At this time, the protrusion moves to below the limiting block and cannot exit the limiting groove under the action of the limiting block, thereby restricting the second piece 321b connected to it in the limiting groove, and finally fixing the buckle 321 in the limiting groove.

[0038] In one embodiment, the end of the second piece 321b away from the first piece 321a is further provided with a pressing part 321c. The pressing part 321c is used to drive the second piece 321b to elastically deform toward the body 31 under the action of external force. When the buckle 321 is engaged in the slot 221, the pressing part 321c protrudes from the slot 221. The pressing part 321c is located at the top of the second piece 321b. When the buckle 321 is engaged in the slot 221, the pressing part 321c will protrude from the slot 221, that is, protrude from the first side edge, so that the buckle 321 has a force application point. The operator can apply external force to the buckle 321 through the protruding pressing part 321c, thereby removing the buckle 321 from the limiting groove and disassembling the cover plate 3.

[0039] Please see Figure 1 , 3 In one embodiment, the air box 1 further includes a paper curtain device 4, which is detachably installed on the side of the air box 1 closest to the interior. The air box 1 is covered by the paper curtain device 4 to close the inlet and outlet 11. The paper curtain device 4 includes a baffle and a paper curtain. The baffle is located on the side of the paper curtain device 4 closest to the interior, and the paper curtain is installed on the side of the baffle closest to the first chamber. An air inlet is opened on the baffle corresponding to the position of the paper curtain, so that the air entering from the air inlet can pass through the paper curtain. When the air cooler is working, cooling water will continuously flow on the paper curtain of the paper curtain device 4. When hot air enters the air box 1 from the inlet and outlet 11, it will first pass through the paper curtain device 4, thereby reducing the air temperature.

[0040] This utility model also proposes a cooler, which includes any of the above-mentioned casing 100. The specific structure of the casing 100 is as described in the above embodiments. Since this cooler adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here. When the operator needs to repair the equipment in the cooler's water tank 2, the water in the water tank 2 is first released through the water valve, the paper curtain device 4 at the inlet and outlet 11 is removed, opening the inlet and outlet 11, allowing entry into the air box 1. Then, the cover plate 3 is opened, allowing entry into the water tank 2 to repair the equipment in the bottom water tank 2 without having to go outside, thus improving the efficiency of cooler repair. The above descriptions are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made using the description and drawings of this utility model under the technical concept of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
