Description

Technical Field

[0001] This application relates to the field of evaporative humidification devices, and in particular to a support structure and electrical equipment. Background Technology

[0002] With the development of technology and the improvement of living standards, people's requirements for the comfort of their living environment are also gradually increasing. As an evaporative cooling device that falls between a fan and an air conditioner, evaporative air coolers are widely used in people's production and daily life, effectively improving their living and working environments. An evaporative air cooler typically includes a water tank, a delivery pump, an evaporation unit, and a fan. The delivery pump draws water from the tank and distributes it to the evaporation unit to form a water film. External airflow is drawn in at high speed by the fan, causing the water on the water film to rapidly evaporate from a liquid state to a gaseous state, absorbing heat from the airflow. The cool air is then delivered at high speed through the air vents, achieving the cooling function.

[0003] As people's aesthetic requirements gradually increase, air coolers are becoming smaller in size while ensuring good cooling function. Since the water tank and evaporation components are connected by pipes, how to simplify the pipe layout while meeting water circulation requirements and further optimize the internal structure and size of air coolers has become an urgent problem for those skilled in the art. Summary of the Invention

[0004] Therefore, it is necessary to provide a support structure and electrical equipment to address the problem that the complex internal structure of air coolers is not conducive to miniaturization.

[0005] A support structure having a water tank mounting position and at least one pipe passage gap, the pipe passage gap being located outside the water tank mounting position, the water tank mounting position being used to install a water tank assembly, and the pipe passage gap being used to run connecting pipes.

[0006] In one embodiment, the support structure includes a support frame and a housing, the water tank mounting position is formed on the support frame, the housing covers the outside of the support frame, and the pipe running gap is formed between the housing and the support frame.

[0007] In one embodiment, the support frame includes two support portions spaced apart in a first direction, forming the water tank mounting position between the two support portions, and the outer shell includes two sub-shells, each covering a side surface of one support portion away from the other support portion, with the pipe passage gap formed between at least one support portion and the sub-shell covering it.

[0008] An electrical device includes the aforementioned support structure, and the electrical device further includes:

[0009] Water tank assembly, installed at the water tank mounting position; and

[0010] At least one set of connecting pipes, one end of which is connected to the water tank assembly, and the other end is at least partially confined within the pipe run-through gap.

[0011] In one embodiment, each set of connecting pipes includes a main pipe, a branch pipe, and two sub-pipes, one end of the main pipe being connected to the water tank assembly, and the other end of the main pipe being connected to the two sub-pipes through the branch pipe.

[0012] In one embodiment, the main body further includes a support shell located at one end of the water tank assembly, the support shell having a receiving cavity communicating with the pipe clearance, and the diversion pipe located within the receiving cavity.

[0013] In one embodiment, one end of the main pipe is connected to the water tank assembly, and the other end of the main pipe extends through the pipe clearance into the receiving cavity to connect to the branch pipe. One end of the sub-pipe extends into the receiving cavity to connect to the branch pipe, and the other end of the sub-pipe extends into the pipe clearance.

[0014] In one embodiment, the water tank assembly includes a primary water tank and a secondary water tank. The secondary water tank is located below the primary water tank and is connected to the primary water tank. The secondary water tank has a connecting port that connects to the pipe gap. The connecting port is higher than the highest water level line of the secondary water tank.

[0015] In one embodiment, the electrical equipment further includes a head unit, which is installed at one end of the support structure. The head unit has two sets of evaporation components spaced apart along the first direction, and each set of connecting pipes connects to both sets of evaporation components.

[0016] In one embodiment, the electrical device is a cooling fan.

[0017] The aforementioned support structure has at least one pipe passage gap on the outside of the water tank installation position, so the connecting pipe can be hidden in the pipe passage gap. On the one hand, this prevents the connecting pipe from being exposed, improving the overall aesthetics of the electrical equipment equipped with this support structure. On the other hand, it optimizes the internal structure of the support structure, simplifies the pipe layout, and facilitates the assembly and maintenance of the electrical equipment.

[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0029] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0033] See Figure 1 and Figure 2 This application provides an electrical device 100. The structure of the electrical device 100 is described below using a cooling fan as an example. This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the electrical device 100 may be other devices, such as a humidifier or an air purifier, which are not limited here.

[0034] The electrical device 100 includes a base 20, a main body 40, and a fan head. The base 20 has a disc-shaped structure, the main body 40 is mounted on the base 20, and the fan head is mounted at the end of the main body 40 away from the base 20. The main body 40 includes a support structure 41 and a water tank assembly 45 mounted on the support structure 41. The fan head includes an air duct assembly and two sets of evaporation components 61 mounted on the air duct assembly. The two sets of evaporation components 61 can be spaced apart along a first direction, and each set of evaporation components 61 is interconnected with the water tank assembly 45 through two sets of connecting pipes 80. It is understood that the number of connecting pipes 80 is not limited to this; in some other embodiments, the electrical device 100 may also include only one set of connecting pipes 80.

[0035] In this way, the air duct assembly can be used to generate directional airflow. Water in the water tank assembly 45 enters the evaporation assembly 61 through one set of connecting pipes 80 and evaporates and absorbs heat on the evaporation assembly 61, thereby humidifying and cooling the airflow flowing through the evaporation assembly 61. Water that has not evaporated on the evaporation assembly 61 flows back to the water tank assembly 45 through another set of connecting pipes 80, thereby realizing the recycling of water.

[0036] In this application, as Figures 3 to 5 As shown, the support structure 41 has a water tank mounting position 41a and at least one pipe passage gap 41b. The pipe passage gap 41b is located outside the water tank mounting position 41a. The water tank mounting position 41a is used to install the water tank assembly 45, and the pipe passage gap 41b is used to run the connecting pipe 80.

[0037] Thus, at least one pipe run-through gap 41b is provided on the outside of the water tank mounting position 41a, so the connecting pipe 80 can be hidden in the pipe run-through gap 41b. On the one hand, this prevents the connecting pipe 80 from being exposed, improving the overall aesthetics of the electrical equipment 100 with the support structure 41. On the other hand, it optimizes the internal structure of the support structure 41, simplifies the pipe layout, and facilitates the assembly and maintenance of the electrical equipment 100.

[0038] As a preferred embodiment, the support structure 41 has two pipe clearances 41b, which are located on opposite sides of the water tank mounting position 41a in the first direction. Therefore, the two sets of connecting pipes 80 can be hidden in the two pipe clearances 41b and located on opposite sides of the water tank mounting position 41a.

[0039] Specifically, the support structure 41 includes a support frame 412 and a housing 414. The support frame 412 extends from one end connected to the base 20 to one end connected to the fan head along a second direction perpendicular to the first direction. A water tank mounting position 41a is formed at one end of the support frame 412 near the base 20. The housing 414 covers the opposite sides of the support frame 412 in the first direction. The housing 414 and the support frame 412 can be fixedly assembled by means of snap-fit ​​connection, screw connection, etc. A pipe passage gap 41b is formed between the housing 414 and the support frame 412. In the following embodiments, when the cooling fan is placed on a horizontal bearing surface such as the ground, the second direction (i.e. Figure 3 The Z direction in the equation is parallel to the vertical direction, and the first direction (i.e., Figure 3 The X direction in the figure is parallel to the horizontal direction.

[0040] More specifically, the support frame 412 includes two support portions. The two support portions are spaced apart in a first direction, and the length direction of the support portions is parallel to a second direction, forming a water tank mounting position 41a between the two support portions for mounting the water tank assembly 45.

[0041] The outer casing 414 includes two sub-casings. Both sub-casings are elongated structures with their length direction parallel to the second direction. The shape of the sub-casings matches the shape of the support. The two sub-casings cover the side surface of one support away from the other support. A tube passage gap 41b is formed between at least one support and the sub-casing covering it. Each tube passage gap 41b extends from one end of the support structure 41 near the base 20 along the second direction to one end of the support structure 41 near the machine head.

[0042] Furthermore, each support unit has two first communication ports 4121a at one end near the base 20, connecting the water tank assembly 45 and the pipe gap 41b. The end of the sub-outer shell connected to the support unit and the machine head forms a second communication port connecting the pipe gap 41b and the machine head. Therefore, the pipe assembly can extend into the pipe gap 41b through the first communication port 4121a and extend out of the pipe gap 41b through the second communication port to connect with the evaporation assembly 61.

[0043] Please continue reading. Figures 3 to 5 In the two sets of connecting pipes 80, one set of connecting pipes 80 serves as the water inlet pipe for water in the water tank assembly 45 to flow to the evaporator assembly 61, and the other set of connecting pipes 80 serves as the water outlet pipe for water in the evaporator assembly 61 to flow back to the water tank assembly 45, thus forming a complete water circulation. One end of each set of connecting pipes 80 is connected to the water tank assembly 45, and the other end is at least partially confined within the pipe clearance 41b. The pipe clearance 41b serves to limit, protect, and conceal the connecting pipes 80, preventing them from becoming entangled or damaged, and avoiding the connecting pipes 80 being exposed outside the electrical equipment 100, thus affecting the overall aesthetics of the electrical equipment 100.

[0044] In some other embodiments, the electrical device 100 may consist of only a set of connecting pipes 80 as a water supply pipe for water in the water tank assembly 45 to the evaporation assembly 61, and excess water in the evaporation assembly 61 may be directly returned to the water tank assembly 45.

[0045] Specifically, each set of connecting pipes 80 includes a main pipe 81, a branch pipe 83, and two sub-pipes 85. The branch pipe 83 is a tee pipe with three interconnected ports. One end of the main pipe 81 is connected to the water tank assembly 45, and the other end of the main pipe 81 is connected to one port of the branch pipe 83. The other two ports of the branch pipe 83 are each connected to a sub-pipe 85.

[0046] Thus, the water in the water tank assembly 45 enters the two evaporation assemblies 61 through the main pipe 81, the branch pipe 83 and the two sub-pipes 85 of one set of connecting pipes 80, and the water in the two evaporation assemblies 61 flows back to the evaporation assembly 61 through the two sub-pipes 85, the branch pipe 83 and the main pipe 81 of another set of connecting pipes 80.

[0047] By setting up the diversion pipe 83, the water flowing out of the main pipe 81 can be divided into two and flow into two sub-pipes 85 respectively, or the water flowing out of the two sub-pipes 85 can be merged into one main pipe 81. Thus, only two main pipes 81 need to be directly connected to the water tank assembly 45, thereby simplifying the water circuit structure in the main body 40 and effectively reducing the overall volume of the support structure 41.

[0048] Please combine Figure 1 and Figure 4 , Figure 5 As shown, in some embodiments, the main body 40 further includes a support shell 43. The support shell 43 has a hollow cylindrical structure. The support shell 43 is connected between two support parts and disposed between two pipe gaps 41b. It is located at the end of the water tank assembly 45 away from the base 20 in the second direction. The support shell 43 has a receiving cavity 43a that communicates with the pipe gaps 41b. The diversion pipe 83 is located in the receiving cavity 43a. Each support part has a third connecting port and a fourth connecting port that communicate with the receiving cavity 43a and the pipe gaps 41b. The fourth connecting port is spaced apart on the side of the third connecting port near the machine head.

[0049] Thus, taking one set of connecting pipes 80 as an example, one end of the main pipe 81 is connected to the water tank assembly 45, and the other end of the main pipe 81 passes through the pipe passage 41b, and then passes through the third connecting port to extend into the receiving cavity 43a to connect to the branch pipe 83. One end of each of the two sub-pipes 85 is located in the receiving cavity 43a to connect to the branch pipes 83 respectively, and the other ends of each of the two sub-pipes 85 pass through the fourth connecting port to extend into the two pipe passages 41b respectively, and then extend out of the second connecting port from the support structure 41 to connect to the evaporation assembly 61.

[0050] Please see Figure 2 and Figure 3 In some embodiments, the water tank assembly 45 includes a primary water tank 452, a secondary water tank 454, and a delivery pump 456. The secondary water tank 454 is located below and connected to the primary water tank 452. One set of main pipes 81 of connecting pipes 80 is connected to the outlet of the delivery pump 456, and another set of main pipes 81 of connecting pipes 80 is directly connected to the secondary water tank 454.

[0051] In this way, the user can inject water into the primary water tank 452, and the water in the primary water tank 452 can gradually flow into the secondary water tank 454. The delivery pump 456 can draw water from the secondary water tank 454 and then deliver it to the connecting pipe 80, which serves as the water supply pipe. The connecting pipe 80 then delivers the water to the evaporation unit 61. Excess water in the evaporation unit 61 flows back to the secondary water tank 454 through another set of connecting pipes 80.

[0052] As a preferred embodiment, the lowest point of the outlet of the primary water tank 452 is lower than the highest water level of the secondary water tank 454.

[0053] Thus, when the water volume in the secondary water tank 454 is large and the water level is higher than the lowest point of the outlet, the outlet is sealed by the water in the secondary water tank 454. Under the action of atmospheric pressure, the water in the primary water tank 452 automatically stops flowing into the secondary water tank 454, thereby preventing the water in the secondary water tank 454 from overflowing due to excessive water.

[0054] As water in the secondary water tank 454 is continuously transported to the evaporation component 61 by the transfer pump 456, the water level in the secondary water tank 454 drops until it is below the lowest point of the outlet. At this point, the outlet is not sealed, and the primary water tank 452 is connected to the outside atmosphere. Therefore, the water in the primary water tank 452 flows back into the secondary water tank 454 until the water level in the secondary water tank 454 is again above the lowest point of the outlet.

[0055] Therefore, the primary water tank 452 achieves automatic water discharge through atmospheric pressure, thereby maintaining the water in the secondary water tank 454 within a certain range, thus keeping the working state of the transfer pump 456 in the secondary water tank 454 stable to ensure constant humidification efficiency, while preventing excessive water in the secondary water tank 454 from overflowing.

[0056] Furthermore, the secondary water tank 454 has two connecting ports that are respectively connected to the pipe gap 41b. The height of each connecting port in the first direction is higher than the highest water level line of the secondary water tank 454, and the delivery pump 456 is installed inside the secondary water tank 454. In one embodiment, the tank wall of the secondary water tank 454 can be integrally formed with the support part of the support structure 41. Therefore, the connecting port connecting the secondary water tank 454 is the first connecting port 4121a on the support part.

[0057] Thus, one end of the main pipe 81 in the connecting pipe 80, which serves as the water supply pipe, is connected to the outlet of the delivery pump 456, and the other end passes through the connecting port and the support frame 412 in sequence before entering the pipe clearance 41b. Since the connecting port is higher than the highest water level line of the secondary water tank 454, water leakage from the secondary water tank 454 through the connecting port can be prevented.

[0058] The aforementioned support structure 41 and the electrical equipment 100 thereon not only provide support, but also form a water tank mounting position 41a for installing the water tank assembly 45 and pipe clearances 41b on opposite sides of the water tank mounting position 41a, thereby effectively optimizing the overall structure of the electrical equipment 100 and facilitating the miniaturization of the overall size of the electrical equipment 100.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
