Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, and particularly relates to a waterproof humidifier fan. Background Art

[0002] A humidifier is a household appliance that increases the humidity of a room. A humidifier can humidify a designated room or be connected to a boiler or central air conditioning system to humidify an entire building. A heat evaporation type humidifier, also called an electrothermal humidifier, works by heating water to 100 degrees in a heating element to generate water vapor, and using a fan to send out the vapor. The humidification method of an electrothermal humidifier is the simplest, and its air supply is mainly completed by a fan.

[0003] Such humidifiers in the prior art generally include a humidifier base and a humidifier housing. The upper end of the humidifier base is connected to the humidifier housing. A humidifier fan is installed on the humidifier base and is also connected to a humidifier filter. A humidifier humidifying cotton is installed inside the humidifier housing, and a humidifier water tank is also installed. Water flow contacts the humidifier humidifying cotton, making the entire humidifier humidifying cotton full of water. Under the action of the fan, the flowing air evaporates the water of the humidifier humidifying cotton and enters the room with the air flow for humidification. In addition, there is also a form of directly generating water vapor through electric heating. Figure 3 As shown in the traditional fan, since the end face of its wind wheel is set in a bowl shape, it is easy to cause water accumulation, resulting in the motor circuit getting water and being unable to be used during long-term use, and further improvement is needed. Content of the Utility Model

[0004] The purpose of the utility model is: aiming at the deficiencies in the above background art, to provide a structure with better water guiding effect, so that the waterproof effect of the fan during long-term use is better.

[0005] To achieve the above purpose, the utility model provides a waterproof humidifier fan, which includes a wind wheel and a motor. The wind wheel includes a plurality of impellers distributed around, and a wind guide ring and a connecting ring located at the upper edge and lower edge of the impellers respectively and connecting all the impellers into one body. The motor is arranged at the central position of the wind wheel, and the rotor of the motor is connected to the wind wheel;

[0006] The wind guide ring is in a bowl shape with the bowl opening upward, and a drain hole is opened on the wind guide ring for draining water in the wind guide ring.

[0007] Further, a plurality of drain holes are provided and are symmetrically distributed in a ring around the rotation center of the wind guide ring.

[0008] Further, the drain hole is arranged at the lowest position on the upper surface of the wind guide ring to prevent the water accumulated in the wind guide ring from not being able to enter the drain hole.

[0009] Further, the edge position of the air guide ring is provided with a hollow-out structure.

[0010] Further, the part where the air guide ring is connected to the upper edge of the impeller is reduced.

[0011] The above solution of the present utility model has the following beneficial effects:

[0012] The waterproof humidifier fan provided by the present utility model, through the arrangement of the drainage holes on the air guide ring and the modification of the edge position of the air guide ring, can significantly reduce the phenomenon of water accumulation in the air guide ring above the wind wheel during the service life of the humidifier. Therefore, the risk of the motor failing due to water ingress is significantly reduced, and the improvement method is simple with low application cost. In addition, it will not have an obvious impact on the structural strength, air supply efficiency, etc. of the wind wheel, improving the reliability of the fan and the humidifier.

[0013] Other beneficial effects of the present utility model will be described in detail in the subsequent specific implementation part. Description of the Drawings

[0019] In order to make the technical problems, technical solutions and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0021] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a locking connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] As Figure 1 , Figure 2 shown, an embodiment of the present utility model provides a waterproof humidifier fan, which includes a wind wheel 1 and a motor 2. Among them, the wind wheel 1 generally adopts an integral structure, including a plurality of impellers 3 distributed around and a wind guide ring 4 and a connection ring 5 located at the upper and lower edges of the impellers 3 and connecting all the impellers 3 into one body respectively. The motor 2 is arranged at the central position of the wind wheel 1, and the rotor of the motor 2 is connected to the whole wind wheel 1 (specifically, the center of the wind guide ring 4). When powered on, the rotor rotates to drive the wind wheel 1 to rotate synchronously.

[0023] Among them, in order to improve the air guiding effect, when the fan is installed inside the humidifier, the wind guide ring 4 is in the shape of a bowl with the bowl mouth facing upward. Therefore, during long-term use, the water vapor inside the humidifier will accumulate on the upper surface of the wind guide ring 4, form liquid water and may invade the inside of the motor 2, resulting in the failure of the motor 2. Based on this, in this embodiment, a drain hole 6 is opened on the wind guide ring 4, and the water in the wind guide ring 4 can be discharged in time through the drain hole 6, avoiding its long-term accumulation around the motor 2 and causing the motor 2 to be flooded.

[0024] It can be understood that during the rotation of the wind wheel 1, the space below the wind wheel 1 is in a negative pressure state with rapid air circulation. Therefore, the water accumulated in the wind guide ring 4 can be discharged downward from the drain hole 6 relatively quickly and can fall back into the water tank for recycling, etc.

[0025] As a preferred embodiment, a plurality of drainage holes 6 are provided in this embodiment, and are annularly symmetrically distributed around the rotation center of the air guide ring 4, so that the water in each part of the air guide ring 4 can be drained as smoothly as possible while ensuring the overall structural strength of the wind wheel 1. It can be understood that the drainage holes 6 are preferably provided at the lowest point of the upper surface of the air guide ring 4 to prevent water from gathering at the lowest point and being unable to enter the drainage holes 6.

[0026] As a preferred embodiment, the edge of the air guide ring 4 in this embodiment is hollowed out, or the edge of the air guide ring 4 is completely eliminated, that is, the portion where the air guide ring 4 is connected to the upper edge of the impeller 3 is reduced (the outer diameter of the air guide ring 4 is reduced). Therefore, during the rotation of the wind wheel 1, the water at the edge of the air guide ring 4 can be more fully thrown out under the action of centrifugal force, further reducing the degree of accumulation in the air guide ring 4.

[0027] After actual testing, it was found that this arrangement of the air guide ring 4 has little effect on the overall strength of the wind wheel 1, and its air guide efficiency can still be maintained, and will not affect the air outlet effect of the humidifier.

[0028] In other embodiments, the air guide ring 4 may be further modified, for example, it may be changed into an annular structure similar to the connecting ring 5 and connected to the center through a plurality of radial connecting plates. However, the strength and air guide effect of this method need to be further verified.

[0029] Or in other embodiments, the waterproof level of the motor 2 itself can be further improved. Of course, the cost of this method is relatively high.

[0030] In summary, by adopting the solution provided in this embodiment, the phenomenon of water accumulation in the air guide ring 4 on the upper part of the wind wheel 1 during the use period of the humidifier can be significantly reduced, thereby significantly reducing the risk of motor 2 failing due to water ingress. The improvement method is simple and the application cost is low. In addition, it will not have a significant impact on the structural strength and air supply efficiency of the wind wheel 1, thereby improving the reliability of the fan and humidifier.

[0031] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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.

[0032] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
