Description

Technical Field

[0001] The present application relates to the field of fans, and in particular to a waterproof high-speed fan for a steam ironing machine. Background Art

[0002] Steam ironing machine is a kind of equipment widely used in home and commercial places, which removes wrinkles from clothes by using high temperature steam. In the structure of steam ironing machine, high-speed fan plays a vital role, which is responsible for quickly delivering steam to the surface of clothes to be treated, or using negative pressure to suck clothes flat.

[0003] At present, the high-speed fans used in the market are mainly driven by motors, which generate strong airflow through high-speed rotating blades. This design can meet the basic needs of steam ironing machines to a certain extent, but it has some obvious shortcomings in actual applications.

[0004] First, the existing high-speed fans do not adequately consider waterproof performance in their structural design. Since the steam ironing machine generates a large amount of steam and water mist during operation, this moisture can easily enter the fan, causing the motor and other electronic components to become damp or even damaged, seriously affecting the fan's service life and safety.

[0005] Secondly, high-speed fans need to operate in a high-temperature environment, and the motor inside the fan will also generate a lot of heat when working. The heat dissipation design of existing fans mainly relies on natural heat dissipation. Since the air duct is used for the high-temperature steam channel, under the existing structure, the motor not only cannot dissipate heat in time, but the high-temperature steam will also conduct heat to the motor, further increasing the motor temperature. Due to the limited effect of natural heat dissipation, the motor is prone to overheating when running in a high-temperature environment for a long time, resulting in problems such as power reduction, shortened life, and even damage.

[0006] These deficiencies in the prior art greatly limit the performance and reliability of the steam ironing machine. Therefore, it is necessary to make technical improvements to address the above problems and develop a high-speed fan with excellent waterproof performance and efficient heat dissipation capacity to meet the use requirements of the steam ironing machine in high temperature and high humidity environments, thereby improving the overall performance and service life of the equipment. Summary of the invention

[0007] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide a waterproof high-speed fan for a steam ironing machine. The fan is waterproof and has a heat dissipation channel for heat insulation and heat dissipation of the fan, which will significantly improve the performance and reliability of the steam ironing machine and meet the market demand for efficient, durable and reliable ironing equipment.

[0008] To achieve the above-mentioned purpose, the present application discloses a waterproof high-speed fan for a steam ironing machine, comprising an air guide, a motor installed in the air guide, and an impeller installed on the main shaft of the motor.

[0009] The air guide is composed of an outer cylinder, a middle cylinder and an inner cylinder which are coaxial and concentric;

[0010] The outer cylinder and the middle cylinder are fixed by a plurality of connecting parts arranged in a ring, so that an annular air guide channel is formed between the outer cylinder and the middle cylinder, and both ends of the air guide channel are open, one end is used as an air inlet, and the other end is made as an air outlet; the inner cylinder is installed in the middle cylinder, and is spaced with the middle cylinder to form an annular heat insulation and heat dissipation channel, one end of the heat insulation and heat dissipation channel is sealed, and the other end is open; the connecting part is hollow to form a connecting channel, and the heat insulation and heat dissipation channel is connected to the air inlet hole on the outer wall of the outer cylinder through the connecting channel; the motor is installed in the inner cylinder, and the main shaft of the motor extends from one end of the inner cylinder to connect and cooperate with the impeller.

[0011] Furthermore, one end of the inner cylinder is provided with a bearing channel and the other end is sealed to form an installation cavity; the motor is installed in the installation cavity of the inner cylinder, and the motor main shaft extends from the bearing channel and is connected to the impeller; the motor main shaft passes through a sealed bearing installed in the bearing channel to seal the installation cavity and make the installation cavity waterproof.

[0012] Furthermore, the middle tube is a heat insulation board.

[0013] Furthermore, the heat-insulating and heat-dissipating channel is open at one end facing the air outlet and is sealed at one end facing the air inlet.

[0014] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0015] 1. Significantly improve the waterproof performance: By installing a sealed bearing in the bearing channel of the inner cylinder, the motor installation cavity is sealed to effectively prevent moisture from entering the motor, ensure the waterproof performance of the motor, extend the service life of the motor, and improve the overall reliability and safety of the equipment.

[0016] 2. Effectively enhance heat dissipation capacity: The fan adopts a coaxial and concentric outer cylinder, middle cylinder and inner cylinder structure. The annular heat-insulating heat dissipation channel between the middle cylinder and the inner cylinder is connected to the air inlet hole on the outer wall of the outer cylinder through a connecting channel to form an efficient heat dissipation structure. It can effectively insulate and dissipate heat for the motor in a high-temperature environment, prevent high-temperature steam from transferring heat to the motor, and ensure stable operation of the motor in a high-temperature environment.

[0017] The above-listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementations will be further disclosed in the examples or other description parts of this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The singular forms "a", "said" and "the" used in the specification include plural forms unless clearly indicated. The terms "include", "comprise" and "contain" used in the specification indicate the presence of the claimed features, but do not exclude the presence of one or more other features.

[0028] like Figure 1-5 As shown, this embodiment describes in detail a waterproof high-speed fan for a steam ironing machine. The high-speed fan mainly includes an air guide 1, a motor 2, an impeller 3 and a sealed bearing 4.

[0029] In the above composition, the air guide 1 is composed of a coaxial and concentric outer cylinder 101, a middle cylinder 102 and an inner cylinder 103. The outer cylinder 101 and the middle cylinder 102 are fixed by a plurality of connecting parts 104, and these connecting parts 104 are arranged between the outer cylinder 101 and the middle cylinder 102 to form an annular air guide channel 106 between the two.

[0030] More specifically, both ends of the air guiding channel 106 are open, one end serves as an air inlet 107 , and the other end serves as an air outlet 108 .

[0031] In terms of materials, the outer cylinder 101 is made of high temperature resistant and corrosion resistant metal or engineering plastic to ensure long-term use in high temperature and high humidity environments.

[0032] It can be understood that the design of the outer cylinder 101 not only provides structural support, but also effectively guides the airflow through the air guide channel 106, so that high-temperature steam or normal-temperature air can smoothly enter from the air inlet 107 and be discharged from the air outlet 108, thereby achieving efficient airflow delivery.

[0033] In this embodiment, the inner tube 103 is installed in the middle tube 102 and is spaced apart from the middle tube 102 to form an annular heat-insulating heat-dissipating channel 109. The heat-insulating heat-dissipating channel 109 is open at one end toward the air outlet and sealed at the other end. At the same time, the heat-insulating heat-dissipating channel 109 is connected to the air inlet 111 on the outer wall of the outer tube 101 through the connecting channel 110 formed by the hollow of the connecting part 104, thereby realizing the air circulation and heat dissipation functions.

[0034] It is understandable that the middle cylinder 102 is made of materials with excellent thermal insulation properties, such as ceramics or special composite materials. These materials have good thermal insulation effects and can effectively prevent high-temperature steam from directly conducting to the thermal insulation and heat dissipation channel 109, thereby better ensuring the normal operating temperature of the motor 2.

[0035] When the steam ironing machine is working, high temperature steam enters the air guide channel 106 through the air inlet 107. The air guide channel ensures that the steam flows from the air inlet 107 to the air outlet 108 along a predetermined path.

[0036] In such a high temperature environment, the motor 2 needs to be kept cool and dry to ensure its stable operation. To this end, the motor 2 is installed in the inner cylinder 103, and an annular heat-insulating heat-dissipating channel 109 is formed between the inner cylinder 103 and the middle cylinder 102, and the heat-insulating heat-dissipating channel 109 serves as a heat dissipation and heat-insulating layer.

[0037] Specifically, when the high-temperature steam or airflow in the air guide channel 106 is discharged, the air in the heat insulation and heat dissipation channel 109 is simultaneously sucked out due to the air viscosity. This air flows through the air inlet 111 on the outer tube 101 to replenish fresh air into the heat insulation and heat dissipation channel 109.

[0038] It is understandable that the external cold air enters the heat insulation channel 109 through the connecting channel 110, takes away the heat, and thus realizes cooling and heat dissipation of the motor 2. This design ensures that the high-temperature steam does not directly contact the motor 2, further avoiding damage to the motor 2 by high temperature.

[0039] It should be understood that the design principle of the heat-insulating heat dissipation channel 109 is to use the kinetic energy and pressure difference of the airflow to form an active heat dissipation system, and to cool the motor 2 through the dynamic movement of the airflow. As mentioned above, in this embodiment, the middle cylinder 102 is made of a material with excellent heat-insulating properties, such as ceramics or special composite materials, which not only blocks the direct conduction of high-temperature steam, but also further isolates the heat source through the low thermal conductivity of the material itself.

[0040] As a further description of this embodiment, the motor 2 is installed in the inner cylinder 103, and the main shaft 201 of the motor 2 extends from one end of the inner cylinder 103 and is connected to the impeller 3. The impeller 3 is made of high-temperature resistant and high-strength materials, such as aluminum alloy or high-performance engineering plastics, to ensure stability under high-speed rotation and high-temperature environments. The design of the impeller 3 generally includes a plurality of blades 301, which are installed on the hub 302 at a certain angle, and can generate air pressure on one side of the blade 301 under the drive of the motor 2, thereby realizing high-speed airflow drive.

[0041] In the specific structure, one end of the inner cylinder 103 is provided with a bearing channel 112, and the other end is sealed by a tail cover 114 to form a waterproof installation cavity 113. The main shaft 201 of the motor 2 extends through the sealed bearing 4 installed in the bearing channel 112. The sealed bearing 4 not only supports the rotation of the main shaft of the motor, but also provides a waterproof function, effectively preventing moisture from entering the installation cavity, and keeping the motor installation cavity dry.

[0042] In addition, the power connection end of the motor 2 is led out from the installation cavity 113 through a high temperature resistant cable 202, and the tail end of the cable 202 is connected to a connection terminal 203, which is used to connect to an external control board (not shown in the figure) and a power supply (not shown in the figure) to realize the working power supply and working control of the motor 2. The motor 2 can work according to the predetermined operating requirements.

[0043] It should be understood that these high temperature resistant cables 202 are made of high temperature resistant and corrosion resistant materials to ensure that the high temperature resistant cables 202 can still stably transmit power and signals when exposed to high temperature environments. Structurally, the high temperature resistant cables 202 are led out through the sealed end of the installation cavity 113 and are sealed by a dedicated seal to prevent moisture and steam from entering the interior of the installation cavity 113.

[0044] The above design, through the application of multi-layer structure and sealing technology, not only realizes efficient airflow delivery and efficient heat dissipation of motor 2, but also significantly improves the waterproof performance of motor 2. The waterproof high-speed fan can operate stably for a long time in a high temperature and high humidity environment, greatly improving the performance and reliability of the steam ironing machine. Its structural design not only takes into account the waterproof and heat dissipation functions, but also ensures the long-term reliability and stability of the fan under high load.

[0045] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
