Description

Technical Field

[0001] The present application relates to a fan, and in particular to a washable fan. Background Art

[0002] After using electrical appliances with air outlet structures such as fans and air conditioners for a period of time, a lot of dust will accumulate at the air inlets and outlets, making them difficult to clean. At present, the air inlet and outlet nets of some fans are detachable, and users can clean these parts after disassembly, but tools are usually required to disassemble or install them, which provides a poor user experience. In addition, after disassembling the air inlet and outlet nets, users can easily touch the rotating blades or moving parts, which can easily cause danger. Because the fan is equipped with circuits and electrical appliances, ordinary fans cannot be washed with water.

[0003] CN214698405U discloses a fan that can be washed with water. The motor assembly includes a PCBA board, a stator core and a rotor shaft. The inner center of the rear cover is provided with a positioning groove that opens forward. The PCBA board is installed in the positioning groove in pairs, and potting glue is poured into the positioning groove. The potting glue covers the PCBA board to ensure that water does not penetrate into the positioning groove during water washing to ensure that the PCBA board is not affected by water washing. The surface of the stator core is soaked with waterproof three-proof paint, so that the fan head has good overall waterproof performance and can be directly washed with water. The method of potting glue can only achieve sealing in a small range, and it is impossible to pot and seal a larger area. In addition, the cost of potting glue sealing is also relatively high.

[0004] Therefore, there is a need in the prior art for a washable fan that can achieve a wide range of waterproof sealing, thereby being easy to wash and having a low cost. Utility Model Content

[0014] In order to make the purpose, technical solution and advantages of the present application more clear, the embodiments of the present application will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0015] like Figure 1-3 As shown, a washable fan according to the present application includes a housing, on which an air inlet and an air outlet are provided; a wind wheel 11 and a driving motor 15 are provided inside the housing, an upper partition 10 is provided on the top of the wind wheel 11, and a middle partition 13 is provided at the bottom of the wind wheel. Specifically, the upper partition 10 can be arranged at the top shaft 30 of the wind wheel, and the middle partition 13 can be arranged at the bottom mounting portion 40 of the wind wheel. Preferably, a lower partition 25 can also be provided at the bottom of the housing. Among them, the housing can include a front housing 1 and a rear housing 12 that are mutually buckled to form an integral structure, the air inlet can be arranged on the rear housing 12, and the air outlet can be arranged on the front housing 1. The upper partition 10 and the middle partition 13 are sealed and engaged with the housing, and preferably, a sealing ring can be provided to form a separate washable area in the area where the wind wheel 11 is located, so that the air inlet and the air outlet can be washed. Those skilled in the art know that other areas inside the housing except the wind wheel area can be waterproofed by existing sealing means, which will not be repeated. The arrangement of the lower partition plate 25 can prevent water from flowing into the working space of the synchronous motor from the lower part of the fan. The lower partition plate 25 may not be arranged, but the position below the middle partition plate 13 may be arranged as an integral sealing area.

[0016] like Figure 1 As shown, the interior of the shell is also fixedly provided with an air guide plate 3 and an air blocker 4, and the air guide plate 3 and the air blocker 4 can be arranged on the front shell 1 in the manner of the prior art, and no further description is given. A top cover assembly is arranged above the upper partition 10, including a control panel 5, a top cover 6, an electronic board 7 and an electronic board protection box 8, and the upper partition 10 is fixed to the front shell 1 by limiting ribs. Preferably, a sealing ring can also be arranged at the contact portion between the upper partition 10 and the shell. The wind wheel 11 is fixed to the shell through the wind wheel cap bracket 9, the electronic board protection box 8 is arranged above the wind wheel cap bracket 9, the electronic board 7 is arranged in the electronic board protection box 8 and covered with a top cover 6, and a control panel 5 is arranged above the top cover 6. In the present application, by arranging the upper partition 10 and sealing the top cover assembly above the upper partition 10, it can be achieved that when the fan is washed with water, the water flowing in through the air inlet and outlet at the wind wheel cannot flow into the top cover assembly, so as to protect the electrical appliances in the top cover assembly.

[0017] A motor assembly is provided below the middle partition 13, and the motor assembly includes a motor 15, and the motor 15 is used to drive the wind wheel 11 to rotate. The motor 15 can be fixedly installed on the housing through the upper motor bracket 14 and the lower motor bracket 16. A synchronous motor 17 is provided below the lower motor bracket 16, and the synchronous motor 17 is fixed on the synchronous motor bracket 20, and the synchronous motor bracket 20 is fixed on the housing. The synchronous motor 17 is connected to the rotating disk 23 through a connecting rod 18 and an eccentric component 19. Among them, the eccentric component 19 can be fixed on the synchronous motor 17 by a pin, and the connecting rod 18 can be fixed on the eccentric component 19 by a screw. A shaft sleeve 21 is provided at the bottom of the synchronous motor bracket 20, and the shaft sleeve 21 can be fixed on the rotating disk 23 by a limiting column, and the friction plate 22 can be fixed on the rotating disk 23 by a limiting column. The rotating disk 23 is installed on the chassis 26 through the rotating disk cover 24. The lower partition 25 is arranged between the rotating disk cover 24 and the chassis 26, and can be fixed to the front shell by limiting ribs.

[0018] like Figure 3 As shown, an upper water outlet 41 and a middle water outlet 42 are respectively provided on the shell near the upper partition 10 and the middle partition 13 to flow out all the moisture that may exist in the shell. During water washing, water can flow in from the air inlet and the air outlet to clean the wind wheel, but will not flow into the top assembly or the motor assembly and the shaking assembly under the wind wheel. Preferably, a lower water outlet 43 can also be provided under the lower partition 25 to prevent water accumulation. The present application isolates the water washing area from other power consumption areas by setting a partition, so that the whole machine cleaning of the fan can be achieved at a low cost.

[0019] A washable fan according to the present application has the following technical advantages:

[0020] (1) The present application uses a partition to isolate the area where the wind wheel is located from the areas above and below it, so that when the whole machine is washed with water, only the area where the wind wheel is located is cleaned, that is, the wind wheel and the front and rear air inlets are cleaned in particular, and the cleaning water will not affect other circuit areas, thereby meeting the requirements for washing the whole machine with water;

[0021] (2) The present application adopts the method of setting a partition in the casing to meet the requirements of water washing of the whole machine, which not only reduces the cost but also meets the requirements of water washing over a large area.

[0022] Although the implementation methods disclosed in this application are as above, the contents described are only implementation methods adopted for facilitating the understanding of this application, and are not intended to limit this application. Any technician in the technical field to which this application belongs can make any modifications and changes in the form and details of implementation without departing from the spirit and scope disclosed in this application, but the scope of patent protection of this application shall still be based on the scope defined in the attached claims.
