Description

Technical Field

[0001] The invention relates to the technical field of household appliances, and in particular to an evaporative cooling fan. Background Art

[0002] The working principle of the evaporative cooling fan is to install a wet curtain at the air inlet of the evaporative cooling fan, and set a water distribution structure above the wet curtain. The bottom of the water distribution structure has a water outlet hole, and water is transported to the wet curtain from the water outlet hole. The wet curtain can absorb water and increase the contact area between water and air, thereby increasing the evaporation of water on the wet curtain and reducing the temperature of the wind entering from the air inlet, so as to achieve the purpose of transporting relatively low temperature cold air to the surrounding environment.

[0003] However, since the wet curtain is an additional functional component, when the user disassembles it for maintenance, even if the user forgets to install the wet curtain, or the user does not need the cold air with a lower temperature and does not want to install the wet curtain, the fan of the evaporative cooling fan can still work and send air to the surrounding environment. However, after the wet curtain is removed, the water distribution structure still supplies water to the location of the wet curtain, resulting in no parts in the evaporative cooling fan that can absorb water. The dripping water splashes in the evaporative cooling fan and splashes onto other electrical components, creating electrical safety hazards. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect of the evaporative cooling fan in the prior art that there is an electrical safety hazard when the wet curtain is not installed, thereby providing an evaporative cooling fan that can still avoid electrical safety hazards when the wet curtain is not installed.

[0005] An evaporative cooling fan, comprising:

[0006] A housing having an open receiving cavity, wherein the receiving cavity is suitable for assembling a wet curtain;

[0007] A water distribution structure is arranged above the accommodating cavity;

[0008] A water receiving device is movably arranged on the inner wall of the accommodating chamber, and the water receiving device includes a water receiving chamber with an opening toward the water diversion structure. The water receiving chamber has a water receiving state directly below the water diversion structure when the wet curtain is not installed in the accommodating chamber; and a non-water receiving state obliquely below the water diversion structure when the wet curtain is installed in the accommodating chamber.

[0009] The water receiving device is rotatably connected to the inner wall.

[0010] The center of gravity of the water receiving device is located on a side of the water receiving chamber close to the wet curtain;

[0011] It also includes at least one limiting structure, which is arranged on the inner wall of the shell and / or the accommodating cavity and is suitable for limiting the rotation angle of the side of the water receiving device away from the center of gravity and / or the rotation angle of the water receiving device on the center of gravity side.

[0012] The two ends of the water receiving device are rotatably connected to the inner wall.

[0013] At least one positioning hole or rotating shaft is respectively provided on both sides of the inner wall, and a rotating shaft or positioning hole which is matched and connected with the positioning hole or rotating shaft is provided on the water receiving device.

[0015] The rotating shaft on at least one side is an elastic structure.

[0016] The water receiving device is slidably connected to the inner wall.

[0017] Also includes:

[0018] An elastic member has one end disposed on the shell and the other end connected to a side of the water receiving device away from the wet curtain. When the elastic member is in a non-compressed state, the water receiving device is in the water receiving state.

[0019] A slideway is arranged on one of the inner wall and the water receiving device, and a sliding shaft moving along the slideway is arranged on the other of the inner wall and the water receiving device.

[0020] The water receiving device is provided with a connecting column connected to the elastic member.

[0021] The bottom of the water receiving chamber is provided with a discharge port, which is suitable for discharging the water in the water receiving chamber out of the shell.

[0022] Also includes:

[0023] A drainage structure is communicated with the discharge port and is suitable for draining water to the outside of the shell.

[0024] The drainage structure is a drainage groove arranged on the shell.

[0025] It also includes: a dustproof net, which is fixedly connected to the shell and is located at the opening of the accommodating cavity close to the wet curtain.

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

[0027] 1. The evaporative cooling fan provided by the present invention provides a accommodating chamber on a shell, in which a wet curtain and a water receiving device are installed. When a user needs wind at a lower temperature and the wet curtain is working, the wet curtain is located directly below the water diversion structure, and the water receiving device is located obliquely below the water diversion structure. The water receiving device and the wet curtain will not interfere with each other, and the wet curtain cools the air before supplying it to the user. When the user does not need wind at a lower temperature or forgets to install the wet curtain, the water receiving chamber of the water receiving device can be located directly below the water diversion structure to receive water output from the water diversion structure and store it in the water receiving chamber, thereby preventing water from splashing inside the evaporative cooling fan when the wet curtain is not installed, thereby avoiding safety hazards caused by water splashing onto electrical components.

[0028] 2. The evaporative cooling fan provided by the present invention sets the center of gravity of the water receiving device on the side of the water receiving chamber close to the wet curtain. Since the center of gravity of the water receiving device is offset on the center of gravity side, the center of gravity side will automatically rotate downward. By setting a limiting structure on the inner wall of the shell and / or the accommodating chamber, the rotation angle of the water receiving device can be limited, so that the water receiving chamber can be directly below the water diversion structure and be in a water receiving state, thereby preventing the water receiving device from rotating excessively and affecting the water receiving effect. At the same time, since the water receiving device can be in the water receiving state only by its own structure without the need to set up other additional structures, the overall structure of the evaporative cooling fan is relatively simple, avoiding the defect of increasing energy consumption due to setting up an additional driving structure.

[0029] 3. The evaporative cooling fan provided by the present invention makes the rotation of the water receiving device more stable and improves the stability of the movement by rotatably connecting both ends of the water receiving device to the inner wall.

[0030] 4. The evaporative cooling fan provided by the present invention can realize that the water receiving device can rotate relative to the accommodating chamber by providing matching positioning holes and rotating shafts on both sides of the inner wall of the accommodating chamber and on the water receiving device, and the structure is relatively simple.

[0031] 5. The evaporative cooling fan provided by the present invention has a rotating shaft disposed on a side of the water receiving device away from the center of gravity, so that the water receiving device can be rotated toward the center of gravity with less effort.

[0032] 6. The evaporative cooling fan provided by the present invention has a rotating shaft on at least one side configured as an elastic structure, so that the rotating shaft of the water receiving device can be elastically deformed during installation, thereby facilitating assembly.

[0033] 7. The evaporative cooling fan provided by the present invention, by providing an elastic member, allows the water receiving device to be extended and retracted under the elastic force of the elastic member to realize a water receiving state and a non-water receiving state, so that the structure of the water receiving device to achieve sliding is relatively simple.

[0034] 8. The evaporative cooling fan provided by the present invention provides a sliding member and a sliding shaft that slide in cooperation with each other on the inner wall and the water receiving device, so that the sliding of the water receiving device is more stable.

[0035] 9. The evaporative cooling fan provided by the present invention provides a connecting column for connecting the elastic member on the water receiving device, so that the assembly of the water receiving device and the elastic member is more convenient, thereby improving the assembly efficiency.

[0036] 10. The evaporative cooling fan provided by the present invention can discharge the water in the water receiving chamber out of the shell by arranging a discharge port at the bottom of the water receiving device, thereby preventing the water from overflowing into the shell when the water receiving chamber is full, which poses a safety hazard.

[0037] 11. The evaporative cooling fan provided by the present invention, by providing a drainage structure, can have a better drainage effect on the water when transferring the water in the water receiving device to the outside of the shell, thereby improving the transmission effect.

[0038] 12. The evaporative cooling fan provided by the present invention has a simpler structure and occupies less space by configuring the drainage structure as a drainage groove provided on the shell, thereby reducing the overall volume of the evaporative cooling fan.

[0039] 13. The evaporative cooling fan provided by the present invention can filter the air entering the wet curtain and improve the cleanliness of the outlet air by fixing the dustproof net on the shell and locating the dustproof net in the accommodating cavity near the opening of the wet curtain.

[0050] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0052] like Figure 1 - Figure 7 As shown, this embodiment provides an evaporative cooling fan, including: a shell 1, a water distribution structure 3 and a water receiving device 4.

[0053] An open accommodating chamber 2 is provided on the shell 1, and the accommodating chamber 2 is suitable for installing a wet curtain 12; a water diversion structure 3 is connected to the top cover 14 of the evaporative cooling fan and is arranged above the accommodating chamber 2; a water receiving device 4 is movably arranged on the inner wall of the accommodating chamber 2, and the water receiving device 4 includes a water receiving chamber 13 with an opening toward the water diversion structure 3, and the water receiving chamber 13 has a water receiving state directly below the water diversion structure 3 when the wet curtain 12 is not installed in the accommodating chamber 2; and, when the wet curtain 12 is installed in the accommodating chamber 2, it is in a non-water receiving state obliquely below the water diversion structure 3.

[0054] By providing an accommodating chamber 2 on the shell 1, a wet curtain 12 and a water receiving device 4 are installed in the accommodating chamber 2. When the user needs wind at a lower temperature and the wet curtain 12 is working, the wet curtain 12 is located directly below the water diversion structure 3, and the water receiving device 4 is located obliquely below the water diversion structure 3. The water receiving device 4 and the wet curtain 12 will not interfere with each other. The wet curtain 12 cools the air before supplying it to the user. When the user does not need wind at a lower temperature or forgets to install the wet curtain 12, the water receiving chamber 13 of the water receiving device 4 can be located directly below the water diversion structure 3 to receive and store the water output from the water diversion structure 3 in the water receiving chamber 13, thereby preventing water from splashing inside the evaporative cooling fan when the wet curtain 12 is not installed, thereby avoiding safety hazards when water splashes onto electrical components, and at the same time, preventing the problem of loud noise caused by water splashing inside the evaporative cooling fan, thereby improving user experience.

[0055] Specifically, the water receiving device 4 in this embodiment is rotatably connected to the inner wall. The center of gravity of the water receiving device 4 in this embodiment is located on the side of the water receiving chamber 13 close to the wet curtain 12; Figure 5 As shown, the evaporative cooling fan also includes two limit blocks 7, which are arranged on the top wall of the accommodating chamber 2 and are suitable for limiting the rotation angle of the side of the water receiving device 4 away from the center of gravity. By setting the center of gravity of the water receiving device 4 on the side of the water receiving chamber 13 close to the wet curtain 12, since the center of gravity of the water receiving device 4 is offset on the center of gravity side, the center of gravity side will automatically rotate downward. By setting the limit blocks 7 on the top wall of the accommodating chamber 2, the rotation angle of the water receiving device 4 can be limited, so that the water receiving chamber 13 can be directly below the water diversion structure 3 and be in a water receiving state, preventing the water receiving device 4 from rotating excessively and affecting the water receiving effect. At the same time, since the water receiving device 4 can be in a water receiving state only by its own structure without the need to set up other additional structures, the overall structure of the evaporative cooling fan is relatively simple, avoiding the defect of setting up an additional drive structure to increase energy consumption. As a convertible embodiment, the structure of the water receiving device 4 may be evenly arranged, and the center of gravity is located at the center of the water receiving device 4, but the water receiving device 4 is set in a water receiving state or a non-water receiving state by the action of an external force, such as the user can manually rotate the water receiving device 4, or a motor is used to directly drive the water receiving device 4 to rotate. As a convertible embodiment, the limiting structure may be a limiting column, or other forms of structure, and the specific number can be set according to actual needs, which will not be repeated here. As a convertible embodiment, the limiting structure may be arranged on the shell 1, or the limiting structure is arranged on the shell 1 and on the inner wall of the accommodating chamber 2. As a convertible embodiment, the limiting structure may limit the rotation angle of the center of gravity side of the water receiving device 4, or the limiting structure simultaneously limits the rotation angle of the center of gravity side and the non-center of gravity side of the water receiving device 4.

[0056] The two ends of the water receiving device 4 in this embodiment are rotatably connected to the inner wall. By rotatably connecting both ends of the water receiving device 4 to the inner wall, the rotation of the water receiving device 4 is more stable, and the stability of the movement is improved. As a convertible embodiment, the water receiving device 4 can also be made of a material with greater strength, so that one end of the water receiving device 4 is rotatably connected to the inner wall on one side, and the other end is not connected to the inner wall on the other side.

[0057] like Figure 4 As shown, in order to realize the stable rotation of both ends of the water receiving device 4, a positioning hole 5 is respectively provided on both sides of the inner wall in this embodiment, and a rotating shaft 6 matched with the positioning hole 5 is respectively provided on both sides of the water receiving device 4. In this embodiment, the material of the rotating shaft 6 is not too limited. As a preferred embodiment, the rotating shaft 6 itself can adopt an elastic structure, so that the rotating shaft 6 of the water receiving device 4 can be elastically deformed when installed, which is convenient for assembly. Specifically, the rotating shaft 6 itself can be made of rubber. By providing the matching positioning holes 5 and the rotating shaft 6 on both sides of the inner wall of the accommodating chamber 2 and the water receiving device 4, the water receiving device 4 can be rotated relative to the accommodating chamber 2, and the structure is relatively simple. As a convertible embodiment, it is also possible that the positioning hole is provided on the water receiving device 4, and the rotating shaft is provided on the inner wall. As a convertible embodiment, it is also possible that the positioning hole 5 and the rotating shaft 6 are provided in plurality. As a convertible embodiment, it is also possible that the inner wall and the water receiving device 4 are directly hingedly connected. As a convertible embodiment, it is also possible that the rotating shafts on both sides are elastic structures, or that the rotating shafts on both sides are non-elastic structures.

[0058] In order to save effort when the water receiving device 4 rotates toward the center of gravity, the rotating shaft 6 in this embodiment is arranged on the side away from the center of gravity of the water receiving device 4. As a convertible embodiment, the rotating shaft 6 can also be arranged at other positions of the water receiving device 4.

[0059] As a convertible embodiment, the water receiving device 4 can also be slidably connected to the inner wall. For example, the evaporative cooling fan also includes an elastic member, one end of which is provided on the housing 1, and the other end is connected to the side of the water receiving device 4 away from the wet curtain 12. When the elastic member is in a non-compressed state, the water receiving device 4 is in a water receiving state. By providing an elastic member, the water receiving device 4 is extended and retracted under the elastic force of the elastic member to achieve a water receiving state and a non-water receiving state, so that the structure of the water receiving device 4 to achieve sliding is relatively simple. In order to facilitate the assembly of the elastic member, a connecting column connecting the elastic member is also provided on the water receiving device 4. In order to make the sliding of the water receiving device 4 more stable, a slideway can be provided on one of the inner wall and the water receiving device 4, and a sliding shaft moving along the slideway can be provided on the other of the inner wall and the water receiving device 4. Of course, the slideway and the sliding shaft can also be omitted.

[0060] like Figure 4 As shown, the bottom of the water receiving chamber 13 in this embodiment is provided with a discharge port 8, which is suitable for discharging the water in the water receiving chamber 13 out of the housing 1. By providing the discharge port 8 at the bottom of the water receiving device 4, the water in the water receiving chamber 13 can be discharged out of the housing 1, preventing the water from overflowing into the housing 1 when the water receiving chamber 13 is full, which poses a safety hazard. As a convertible embodiment, it is also possible that the discharge port 8 is not provided, but the water in the water receiving chamber 13 is manually discharged out of the housing 1 regularly.

[0061] In order to facilitate water drainage, the evaporative cooling fan in this embodiment further includes a drainage structure, which is connected to the discharge port 8 and is suitable for draining water to the outside of the housing 1. By providing the drainage structure, when the water in the water receiving device 4 is transferred to the outside of the housing 1, the water can be better drained, thereby improving the transfer effect. Specifically, as Figure 5 As shown, the drainage structure in this embodiment is a drainage groove 9 provided on the housing 1. By setting the drainage structure as the drainage groove 9 provided on the housing 1, the structure is simpler and occupies less space, so that the overall volume of the evaporative cooling fan is smaller. As a convertible embodiment, the drainage structure can also be a water pipe, which directly leads from the water receiving device 4 to the outside of the housing 1.

[0062] The evaporative cooling fan in this embodiment further includes a dustproof net 11, which is fixedly connected to the housing 1 and located at the opening of the accommodating chamber 2 close to the wet curtain 12. By fixing the dustproof net 11 on the housing 1 and locating the opening of the accommodating chamber 2 close to the wet curtain 12, the air entering the wet curtain 12 can be filtered to improve the cleanliness of the air outlet. As a convertible embodiment, the dustproof net 11 may also be not provided.

[0063] When assembling the evaporative cooling fan, the shell 1 can be first fixed to the air duct of the evaporative cooling fan by screws, and then the top cover 14 can be fixed to the air duct and the shell 1 respectively. Then, when the water receiving device 4 is assembled to the shell 1, the rotating shaft 6 of the non-elastic structure of the water receiving device 4 is first inserted into the positioning hole 5 on one side of the shell 1. Since the rotating shaft 6 at the other end of the water receiving device 4 is an elastic structure, the water receiving device 4 can be assembled to the positioning hole 5 on the other side of the rear shell by force. Because the center of gravity of the water receiving device 4 is on the outside, when there is no external force, the water receiving device 4 will rotate outward. Since a limiting block 7 is provided on the shell 1, the rotation angle of the water receiving device 4 can be ensured, so the water receiving device 4 is always in a water receiving state. When it is necessary to assemble the wet curtain 12 to the accommodating chamber 2 on the shell 1, under the action of the wet curtain 12, the water receiving device 4 rotates and closes to a non-water receiving state. Finally, the dustproof net 11 is assembled to fix the wet curtain 12, thereby completing the assembly.

[0064] like Figure 6As shown, when the user needs wind with a lower temperature, water flows down from the water diversion structure 3 on the top cover 14, and when it falls on the wet curtain 12, it wets the wet curtain 12, and the fan 10 in the air duct works to evaporate the water and take it away; Figure 7 As shown, when the user does not need lower temperature wind and has not installed the wet curtain 12, or the user forgets to install the wet curtain 12, the water receiving device 4 rotates outward to the water receiving state, and water flows down from the water diversion structure 3 on the top cover 14 and directly flows into the water receiving chamber 13 of the water receiving device 4, and then the water flows out from the water outlet opened at the bottom of the water receiving chamber 13. At the same time, a drainage groove 9 is provided at the corresponding position on the shell 1 to drain the water downward to prevent water splashing, avoid splashing water and water flying into the motor, improve product quality, and enhance user experience.

[0065] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
