Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly to an evaporative air cooler. Background Art

[0002] The working principle of an evaporative air cooler is that a wet curtain is installed at the air inlet of the evaporative air cooler, a water distribution structure is arranged above the wet curtain, the bottom of the water distribution structure has water outlet holes, water is conveyed to the wet curtain through the water outlet holes, the wet curtain can absorb water, increasing the contact area between water and air, thereby increasing the evaporation amount of the water on the wet curtain and reducing the temperature of the air entering from the air inlet, so as to achieve the purpose of delivering relatively cold air to the surrounding environment.

[0003] However, since the wet curtain is an additional functional component, when the user disassembles it during maintenance, even if the user forgets to install the wet curtain, or when the user does not need relatively cold air and does not want to install the wet curtain, the fan of the evaporative air cooler can still work and blow air to the surrounding environment. However, after removing the wet curtain, the water distribution structure still supplies water to the position where the wet curtain is located, resulting in no water-absorbing component in the evaporative air cooler, and the dripping water splashes in the evaporative air cooler and may splash onto other electrical components, creating an electrical safety hazard. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that there is an electrical safety hazard in the existing evaporative air cooler when the wet curtain is not installed, so as to provide an evaporative air cooler that can still avoid electrical safety hazards when the wet curtain is not installed.

[0005] An evaporative air cooler includes:

[0006] A bracket, which is provided with a receiving cavity, and the wet curtain is suitable for being assembled in the receiving cavity;

[0007] A water distribution structure, which is arranged on the bracket and is located above the receiving cavity;

[0008] A plurality of water outlet holes, which are arranged at the bottom of the water distribution structure;

[0009] A water blocking structure, which is movably arranged on the water distribution structure, and the water blocking structure makes a translational movement relative to the water distribution structure under the action of an external force, and has a sealed state of blocking the water outlet holes when the wet curtain is not assembled in the receiving cavity; and a water outlet state of opening the water outlet holes when the wet curtain is assembled in the receiving cavity.

[0010] The water blocking structure makes a lifting movement relative to the water distribution structure.

[0011] The water blocking structure includes:

[0012] A water blocking body;

[0013] A plurality of water retaining parts, which are arranged in one-to-one correspondence with the water outlet holes. One end of the water retaining part is connected to the water retaining body, and the other end extends outwards from the water retaining body. When in the sealed state, the other end of the water retaining part is inserted into the water outlet hole.

[0014] It further includes:

[0015] A power device, fixedly connected to the water distribution structure or the bracket. The power device is connected to the water retaining structure and is adapted to drive the water retaining structure to move up and down relative to the water outlet hole.

[0016] The power device is fixedly connected to the top of the water distribution structure, and the output part of the power device is connected to the middle part of the water retaining structure.

[0017] It further includes: a sensing device, which is adapted to sense whether the wet curtain is assembled on the accommodation cavity.

[0018] The sensing device is a photoelectric sensing switch, including a photoelectric emission part and a photoelectric receiving part. One of the photoelectric emission part and the photoelectric receiving part is arranged on the accommodation cavity, and the other is arranged on the side of the water distribution structure close to the accommodation cavity.

[0019] It further includes:

[0020] A controller, connected to the sensing device and the power device. When the sensing device senses that the wet curtain is not assembled on the accommodation cavity, the controller is adapted to control the power device to drive the water retaining structure to move down to the sealed state.

[0021] The water distribution structure includes:

[0022] A water distribution cavity, at the bottom of which the water outlet holes are provided;

[0023] A water storage cavity, which is communicated with the water distribution cavity, and the bottom of the water storage cavity is higher than the bottom of the water distribution cavity. An overflow hole is provided at the bottom of the water storage cavity, which is adapted to drain water out of the water distribution structure.

[0024] A water inlet hole is further provided on the water storage cavity, which is adapted to be communicated with a water source.

[0025] It further includes a sealing device, fixedly connected to the inner wall of the water outlet hole.

[0026] The technical solution of the present invention has the following advantages:

[0027] 1. The evaporative air cooler provided by the present invention has a water blocking structure movably arranged on a water distribution structure and makes a translational movement relative to the water distribution structure under the action of an external force. When the user needs air at a lower temperature and the wet curtain is working, the wet curtain is arranged in the accommodation cavity. The water blocking structure opens the water outlet holes under the action of an external force, enabling the water of the water distribution structure to flow through the water outlet holes to the wet curtain. After the wet curtain cools the air, it is supplied to the user. When the user does not need air at a lower temperature or forgets to install the wet curtain in the accommodation cavity, the water blocking structure blocks the water outlet holes under the action of an external force, preventing the water from the water distribution structure from flowing into the accommodation cavity, preventing water from splashing inside the evaporative air cooler when the wet curtain is not assembled, avoiding potential safety hazards when water splashes onto electrical components, and at the same time, preventing the problem of relatively large noise caused by water splashing inside the evaporative air cooler, thus improving the user experience.

[0028] 2. The evaporative air cooler provided by the present invention has the water blocking structure set to include a water blocking body and water blocking parts, and the water blocking parts are arranged in one-to-one correspondence with the water outlet holes. In the sealed state, the water blocking structure moves downward, and the other end of the water blocking part is inserted into the water outlet hole to block the water outlet hole. In the water outlet state, the water blocking structure moves upward, and the other end of the water blocking part comes out of the water outlet hole to open the water outlet hole. The overall structure of the water blocking structure is relatively simple, and the lifting movement is relatively convenient. At the same time, by adopting the up-and-down movement mode, the water resistance received by the water blocking structure during the movement is relatively small, so the power of the power device itself can be reduced.

[0029] 3. The evaporative air cooler provided by the present invention has a power device fixedly connected to the water distribution structure or the bracket, and the power device drives the water blocking structure to move, so that when an external force needs to act on the water blocking structure to drive it to make a lifting movement, the user does not need to manually operate, resulting in a better user experience.

[0030] 4. The evaporative air cooler provided by the present invention is provided with a sensing device, which can automatically sense whether the wet curtain is assembled on the accommodation cavity, improving the user experience.

[0031] 5. The evaporative air cooler provided by the present invention is provided with a controller connected to the sensing device and the power device. When the sensing device senses that the wet curtain is not assembled on the accommodation cavity, it can automatically control the power device to drive the water blocking structure to move to the sealed state, that is, the sensing action of whether the wet curtain is assembled on the accommodation cavity and the moving action of the water receiving device can all be realized automatically. The user does not need any manual operation, achieving full automation and greatly improving the user experience.

[0032] 6. The evaporative air cooler provided by the present invention is provided with a water distribution cavity and a water storage cavity on the water distribution structure. The bottom of the water storage cavity is higher than the bottom of the water distribution cavity, and an overflow hole is provided at the bottom of the water storage cavity. When the water blocking structure blocks the water outlet hole, water can be discharged outside the water distribution structure through the overflow hole, preventing excessive water accumulation in the water storage cavity from splashing into the interior of the evaporative air cooler and causing potential safety hazards.

[0033] 7. The evaporative air cooler provided by the present invention is provided with a water inlet hole communicating with the water source on the water storage cavity, making it convenient for the water distribution structure to receive water.

[0034] 8. The evaporative air cooler provided by the present invention is fixedly connected with a sealing device on the inner wall of the water outlet hole. When in a sealed state, the sealing effect between the water blocking structure and the water outlet hole is enhanced, further preventing water leakage from the water outlet hole.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0042] The following will clearly and completely describe the technical solutions of the present invention with reference to the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0043] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0044] As Figure 1 - Figure 4 As shown, in this embodiment, an evaporative air cooler is provided, including: a bracket 1, a water distribution structure 11, a water outlet hole 4, and a water blocking structure 5.

[0045] A receiving cavity is provided on the bracket 1, and a wet curtain 2 is adapted to be assembled in the receiving cavity; the water distribution structure is provided on the bracket 1 and is located above the receiving cavity; the water outlet hole 4 is provided at the bottom of the water distribution structure; the water blocking structure 5 is movably provided on the water distribution structure, and the water blocking structure 5 makes a translational movement relative to the water distribution structure 11 under the action of an external force, and has a sealed state of blocking the water outlet hole 4 when the wet curtain 2 is not assembled in the receiving cavity; and a water outlet state of opening the water outlet hole 4 when the wet curtain 2 is assembled in the receiving cavity.

[0046] By movably arranging the water blocking structure 5 on the water distribution structure and making a translational movement relative to the water distribution structure 11 under the action of an external force, when the user needs wind at a lower temperature and the wet curtain 2 is working, the wet curtain 2 is arranged in the receiving cavity, and the water blocking structure 5 opens the water outlet hole 4 under the action of an external force, so that the water of the water distribution structure can flow through the water outlet hole 4 to the wet curtain 2, and the wet curtain 2 cools the air and then supplies it to the user; when the user does not need wind at a lower temperature or forgets to install the wet curtain 2 in the receiving cavity, the water blocking structure 5 blocks the water outlet hole 4 under the action of an external force, so that the water outlet of the water distribution structure does not flow into the receiving cavity, preventing water from splashing inside the evaporative air cooler when the wet curtain 2 is not assembled, avoiding potential safety hazards when water splashes onto electrical components, and at the same time, preventing the problem of relatively large noise caused by water splashing inside the evaporative air cooler, improving the user experience.

[0047] The water blocking structure 5 in this embodiment makes a lifting movement relative to the water distribution structure 11. As an alternative embodiment, it is also possible that the water blocking structure 5 makes a movement in the horizontal direction relative to the water distribution structure 11, that is, the sealed state and the water outlet state are changed by sliding.

[0048] As Figure 4As shown in the figure, the water blocking structure 5 in this embodiment includes: a water blocking body 9, which is arranged in a long strip shape and extends along the arrangement direction of the water diversion holes; at least two water blocking parts 10, which are arranged in one-to-one correspondence with the water outlet holes 4. One end of the water blocking part 10 is connected to the water blocking body 9, and the other end extends outwards from the water blocking body 9. When in the sealed state, the other end of the water blocking part 10 is inserted into the water outlet hole 4. By setting the water blocking structure 5 to include the water blocking body 9 and the water blocking parts 10, and the water blocking parts 10 are arranged in one-to-one correspondence with the water outlet holes 4. When in the sealed state, the water blocking structure 5 moves downwards, and the other end of the water blocking part 10 is inserted into the water outlet hole 4 to block the water outlet hole 4. When in the water outlet state, the water blocking structure 5 moves upwards, and the other end of the water blocking part 10 comes out of the water outlet hole 4 to open the water outlet hole 4. The overall structure of the water blocking structure 5 is relatively simple, and the lifting movement is relatively convenient. At the same time, by adopting the up-and-down movement mode, the water resistance received by the water blocking structure during the movement is relatively small, so the power of the power device itself can be reduced. As a transformable implementation manner, it can also be that the water outlet hole 4 and the water blocking part 10 are one or more. As a transformable implementation manner, it can also be that the water blocking structure 5 includes several water blocking bodies 9, which are arranged in one-to-one correspondence with the water diversion holes, and each water blocking body 9 is provided with a water blocking part 10 that cooperates with the water diversion hole.

[0049] The evaporative air cooler in this embodiment further includes: a power device, which is fixedly connected to the water diversion structure 11, and the power device is connected to the water blocking structure 5 and is adapted to drive the water blocking structure 5 to make a lifting movement relative to the water outlet hole 4. By fixedly connecting the power device to the water diversion structure 11 and the power device driving the water blocking structure 5 to move, when an external force needs to act on the water blocking structure 5 to drive it to make a lifting movement, the user does not need to manually operate, which makes the user experience better. As a transformable implementation manner, it can also be that the power device is fixedly connected to the bracket 1. As a transformable implementation manner, it can also be that the power device is not provided, and the user manually drives the water blocking structure 5 to move.

[0050] Specifically, the power device in this embodiment is a linear motor, and the water blocking structure 5 makes a lifting movement relative to the water outlet hole 4 under the drive of the linear motor to realize the transformation between the sealed state and the water outlet state. As a transformable implementation manner, it can also be that the power device is an ordinary motor, a driving gear is arranged on the motor, a rack is arranged on the water blocking structure 5, and the motor drives the driving gear to rotate, thereby driving the rack to approach or move away from the water outlet hole.

[0051] The linear motor is fixedly connected to the top of the water diversion structure 11. The output rod of the linear motor is connected to the middle of the water blocking body 9 to drive the water blocking structure 5 to move up and down. Since the linear motor is fixedly connected to the top cover of the water diversion structure 11, the linear motor can be kept away from the water inside the water diversion structure 11, preventing electrical safety hazards. At the same time, because the linear motor is arranged in the middle position, it can act steadily on the center of gravity of the water blocking body 9. When the water blocking body 9 moves up and down, it will not tilt. As a transformable implementation manner, it can also be that the linear motor is arranged at other positions of the water diversion structure 11. In order to prevent the linear motor from contacting the water inside the water diversion structure 11, a sealing cavity can also be arranged on the water diversion structure 11, with the linear motor arranged inside the sealing cavity, and the output rod of the linear motor extending out of the sealing cavity and connected to the water blocking body 9. As a transformable implementation manner, it can also be that, since the water blocking body 9 is strip-shaped, multiple linear motors are arranged and connected to multiple positions of the water blocking body 9 respectively to make the movement of the water blocking body 9 more stable.

[0052] The evaporative air cooler in this embodiment further includes: a sensing device adapted to sense whether the wet curtain 2 is assembled on the accommodation cavity. By arranging the sensing device, it can automatically sense whether the wet curtain 2 is assembled on the accommodation cavity, improving the user experience. As a transformable implementation manner, it can also be that the sensing device is not arranged.

[0053] The sensing device in this embodiment is a photoelectric sensing switch, including a photoelectric generator and a photoelectric receiver. The photoelectric generator is arranged on the inner wall of the accommodation cavity away from the water diversion structure 11, and the photoelectric receiver is arranged on one side wall of the water diversion structure 11 close to the accommodation cavity. When the wet curtain 2 is not assembled in the accommodation cavity, the light emitted by the photoelectric generator can be received by the photoelectric receiver on the water diversion structure 11, thereby sending out a signal that the wet curtain 2 is not assembled in the accommodation cavity; when the wet curtain 2 is assembled in the accommodation cavity, the light emitted by the photoelectric generator cannot be received by the photoelectric receiver on the other side, thereby sending out a signal that the wet curtain 2 is assembled in the accommodation cavity. As a transformable implementation manner, it can also be that the photoelectric generator is arranged on one side wall of the water diversion structure 11 close to the accommodation cavity, and the photoelectric receiver is arranged on the inner wall of the accommodation cavity away from the water diversion structure 11. As a transformable implementation manner, it can also be that the sensing device is a squeezing type sensing switch arranged on the inner wall of the accommodation cavity. When the wet curtain 2 is assembled into the accommodation cavity, it gives a squeezing force to the squeezing type sensing switch, and the squeezing type sensing switch is open-circuited. When the wet curtain 2 is not assembled into the accommodation cavity, there is no squeezing force on the squeezing type sensing switch, and the squeezing type sensing switch is in a conducting state.

[0054] The evaporative air cooler in this embodiment further includes: a controller, connected to the sensing device and the linear motor, and adapted to control the linear motor to drive the water-blocking structure 5 to move down to the sealed state when the sensing device senses that the wet curtain 2 is not assembled on the accommodation cavity. By providing a controller connected to the sensing device and the linear motor, when the sensing device senses that the wet curtain 2 is not assembled on the accommodation cavity, it can automatically control the linear motor to drive the water-blocking structure 5 to descend to the sealed state, that is, the sensing action of whether the wet curtain 2 is assembled on the accommodation cavity and the moving action of the water-receiving device can all be realized automatically. The user does not need any manual operation, achieving full automation and greatly improving the user experience. As a transformable implementation manner, it can also be that no controller is provided and the user manually controls it.

[0055] As Figure 3 shown, the water distribution structure 11 in this embodiment includes: a water distribution cavity 3, and a water outlet hole 4 is provided at the bottom of the water distribution cavity 3; a water storage cavity 6, which is arranged adjacent to the water distribution cavity 3 and communicates with the water distribution cavity 3, and the bottom of the water storage cavity 6 is higher than the bottom of the water distribution cavity 3. An overflow hole 7 is provided at the bottom of the water storage cavity 6, which is adapted to discharge water out of the water distribution structure 11. Specifically, the water discharged from the overflow hole 7 can be directly conveyed to the water tank of the evaporative air cooler and used as the water source for re-water supply in a cycle. By providing the water distribution cavity 3 and the water storage cavity 6 on the water distribution structure 11, the bottom of the water storage cavity 6 is higher than the bottom of the water distribution cavity 3, and the overflow hole 7 is provided at the bottom of the water storage cavity 6, so that when the water-blocking structure 5 blocks the water outlet hole 4, the water can be discharged out of the water distribution structure 11 through the overflow hole 7, preventing the water from accumulating too much in the water storage cavity 6 and splashing into the interior of the evaporative air cooler, causing potential safety hazards. As a transformable implementation manner, it can also be that the water discharged from the overflow hole 7 is directly discharged outside the evaporative air cooler.

[0056] For the convenience of water filling, a water filling hole 8 communicating with the water source is further provided on the water storage cavity 6. As a transformable implementation manner, it can also be that the water filling hole 8 is not provided separately, and the upper end opening of the water distribution structure 11 is directly used as the water filling port.

[0057] The evaporative air cooler in this embodiment further includes a sealing device, which is fixedly connected to the inner wall of the water outlet hole 4. Specifically, the sealing device in this embodiment is a sealing ring, which is adhered to the inner wall of the water outlet hole 4, so that in the sealed state, the sealing ring makes the water-blocking part 10 of the water-blocking structure 5 insert into the water outlet hole 4 more tightly through its own elastic deformation, enhancing the sealing effect between the water-blocking part 10 and the water outlet hole 4 and further preventing the water outlet hole 4 from leaking. As a transformable implementation manner, it can also be that no sealing device is provided, or the sealing device is an elastic member of other forms.

[0058] When the evaporative air cooler is working, when the photoelectric induction switch senses that the wet curtain 2 is not assembled in the accommodating cavity, the controller drives the linear motor to drive the water blocking structure 5 to move downward, and the water blocking part 10 is inserted into the water outlet hole 4, so as to achieve the effect of sealing the water outlet hole 4 and preventing water from flowing downward. Since water no longer flows down from the water outlet hole 4 at this time, there is no water flow or water droplets at the air inlet of the evaporative air cooler, preventing the sound of water dripping from a height and splashing, and preventing water from being sucked into the fan of the evaporative air cooler, thus causing electrical safety hazards; at the same time, since water is continuously flowing into the water storage cavity 6, the water level in the water distribution cavity 3 rises to the water storage cavity 6, and water flows back to the water tank from the overflow hole 7, avoiding the safety hazard caused by the water level being too high and overflowing to other places.

[0059] When the evaporative air cooler is working, when the photoelectric induction switch senses that the wet curtain 2 is assembled in the accommodating cavity, the controller drives the linear motor to drive the water blocking structure 5 to move upward, and the water blocking part 10 is pulled out of the water outlet hole 4 to open the water outlet hole 4. Water can flow from the water outlet hole 4 to the wet curtain 2 to wet the wet curtain 2. After the fan of the evaporative air cooler starts, the water evaporates from the wet curtain 2 to realize the function of humidifying and cooling.

[0060] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
