Description

Technical Field

[0001] The present invention relates to the field of heating, and more particularly, to an integrated hot air output device. Background Art

[0002] Currently, small household appliances such as hair dryers, clothes dryers, and hand dryers generally use a resistance wire rack as the core heating element. However, a conventional resistance wire rack converts electrical energy into heat energy, and the heating efficiency is only 65% - 75%. To achieve a rapid heating effect, the power needs to be increased (usually 1300 - 2500W). The heating efficiency is low and the power is large, and the integration of the fan, motor, and heating element is low, resulting in a relatively large volume.

[0003] For example: The "Integrated Structure of Motor Heating Wire" disclosed in the utility model patent (Application No.: 202320643595.7) has the following description in its specification: The heating wire assembly and the motor assembly are installed in the accommodation cavity inside the housing. A plurality of connecting pieces are arranged at intervals in a ring shape on the bracket of the heating wire assembly, and a number of heating wires are arranged between adjacent connecting pieces. An installation seat is arranged on one side of the connecting piece, a part of the motor assembly is installed on the installation seat, and the fan blade is installed at one end of the motor assembly away from the installation seat. An air outlet is also arranged on the housing. The airflow generated by the rotation of the fan blade driven by the motor assembly passes through the heating wires and then flows out from the air outlet. After integrating and assembling the heating wire assembly and the motor assembly, they are installed inside the housing, which greatly shortens the distance of the airflow flowing to the air outlet, reduces the loss of air flow kinetic energy, and through the closed environment inside the housing, the airflow generated by the fan blade is concentrated to pass through the heating wires and then flow out from the air outlet of the housing, avoiding the situation where part of the airflow does not flow to the heating wires; the above patent can prove the defects existing in the prior art.

[0004] Therefore, we make improvements in this regard and propose an integrated hot air output device. Summary of the Invention

[0014] As a preferred technical solution of the present application, a heat conducting ring is fixedly provided on the circumferential side outside the heat conducting cylinder.

[0021] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0022] Example 1 Please refer to Figure 1 and Figure 3 , an integrated hot air output device, which includes a heat conduction cylinder 1. The heat conduction cylinder 1 is used to be installed inside devices such as hair dryers or clothes dryers. The heat conduction cylinder 1 is made of stainless steel or ceramic. Stainless steel such as SUS304, aluminum alloy 6063; Ceramic: such as alumina; It has both mechanical strength and thermal conductivity. A heating component 2 is provided outside the heat conduction cylinder 1. An installation shell 31 is provided inside the heat conduction cylinder 1. A fixed cover 32 is fixedly provided at the rear end of the installation shell 31. A stator 33 is fixedly provided inside the installation shell 31. A rotor is provided inside the stator 33. A rotating shaft 34 is provided inside the rotor. After being powered on, the stator 33 drives the rotor and the rotating shaft 34 to rotate. A blowing component 4 is provided in front of the circumferential side of the rotating shaft 34. The blowing component 4 is used to generate wind through the rotation of the rotating shaft 34. The wind contacts the surfaces of the heating component 2 and the heat conduction cylinder 1 to take away their heat, forming hot air, which can be used for drying clothes, blowing hair, etc.

[0023] Furthermore, as Figure 2 , Figure 3 and Figure 4 shown, the heating component 2 includes an insulating dielectric layer 21. The heat conduction cylinder 1 substrate requires the coefficient of thermal expansion to match that of the insulating dielectric layer 21 to prevent high-temperature cracking; The stainless steel substrate is corrosion-resistant and has a moderate cost. The insulating dielectric layer 21 is used to ensure electrical safety. The insulating dielectric layer 21 covers the outside of the heat conduction cylinder 1. A heating circuit 22 is provided on the insulating dielectric layer 21; The heating circuit 22 is a functional thin film circuit formed by printing and sintering special slurries. The conductive slurry material is made of NiCr nickel-chromium alloy and TaN tantalum nitride. Other optional materials: silver-palladium (Ag-Pd), ruthenium oxide, etc. The powdered conductive material is mixed with glass powder and organic solvents to form a printable paste slurry. The slurry is accurately coated on the substrate through screen printing process; Screen printing uses a screen plate to accurately print the slurry onto the substrate. The hardness (such as 60 degrees) and pressure (0.15 - 0.25 MPa) of the squeegee affect the film thickness uniformity; Form a resistance circuit with a specific shape (such as serpentine, spiral). After the slurry is sintered at high temperature (800 - 1000 °C), the glass powder melts to form a dense structure, and the conductive particles form a continuous network to achieve stable resistance characteristics; Post-treatment: Laser engraving to adjust the resistance value, or stacking multiple layers of structures to increase the power density; After the heating circuit 22 is powered on, the thermal efficiency reaches ≥95%, the starting current is small, the power density can reach 30 W / cm², the power is reduced to 300 - 1000 W, there is no local "hot spot" during use, it is high-temperature resistant (>500 °C), the service life exceeds 10,000 hours, and at the same time, the overall structure is small in volume and high in thermal efficiency; At the bottom end of the heat conduction cylinder 1, two contacts 11 are fixedly provided. The two contacts 11 are electrically connected to the heating component 2. The two contacts 11 are respectively the positive pole and the negative pole. The two contacts 11 are electrically connected to the positive pole and the negative pole of the power supply through the power supply respectively, so as to power on the heating circuit 22 to generate heat, make the heat conduction cylinder 1 conduct heat, and the air flow blown by the blowing component 4 contacts the surfaces of the heat conduction cylinder 1 and the heating component 2 to take away the heat, thereby forming hot air; The insulating dielectric layer 21 and the heating circuit 22 are covered with a protective glaze layer 23 on the outside, and the protective glaze layer 23 can adopt glass-based glaze; The structure composed of the heat conduction cylinder 1 and the heating component 2 is not easily burned out, the working life can reach 1000 hours, and there is no open fire when burned out and it is not easy to cause a fire. In order to increase its applicability in small household appliances, the heat conduction cylinder 1 can be made of different metal substrates such as (stainless steel sus304, 316, 430, 440, aluminum alloy 6063 or increase the thickness, add heat insulation and insulation materials, mica sheets, heat insulation silica gel, etc.); The thickness of the insulating dielectric layer 21 is 85 - 110 microns.

[0024] Furthermore, as Figure 2 and Figure 3 shown, the blowing component 4 includes a connecting seat 41 fixed on the circumferential side of the rotating shaft 34. When the rotating shaft 34 rotates, the connecting seat 41 also rotates accordingly. A number of first fan blades 42 are fixedly provided at equal intervals on the circumferential side of the connecting seat 41. The first fan blades 42 are inclined. When the connecting seat 41 rotates, the number of first fan blades 42 rotates around the connecting seat 41. By the inclination of the first fan blades 42, the wind on one side is attracted to the other side, and the air flow passes through the heat conduction cylinder 1 and the heating component 2 and contacts their surfaces to take away the heat, forming hot air.

[0025] Furthermore, as Figure 5 shown, a heat conduction connection component 5 is provided between the heat conduction cylinder 1 and the installation shell 31. The heat conduction connection component 5 is used to increase the contact area with the wind, thereby improving the heating efficiency, and is used to support the installation shell 31.

[0026] Furthermore, as Figure 3 and Figure 5As shown, the heat-conducting connection component 5 includes a plurality of heat-conducting plates 51 equidistantly fixed to the inner wall of the heat-conducting tube 1. The heat-conducting plates 51 are made of the same heat-conducting material as the heat-conducting tube 1. When the heat-conducting tube 1 conducts heat, it transfers the heat to the heat-conducting plates 51, causing the heat-conducting plates 51 to generate heat. The heat is gathered between the plurality of heat-conducting plates 51. The wind blown out by the blowing component 4 passes through the heat-conducting plates 51, takes away the heat thereof, increases the contact area with the wind, and thus improves the thermal efficiency. A heat-insulating plate 52 is fixedly provided on one side of the heat-conducting plate 51 close to the mounting shell 31. The heat-insulating plate 52 is a non-heat-conducting material, and a ceramic-based material may be used to reduce the heat conducted to the mounting shell 31, the stator 33 and the rotor, and prevent high temperature from affecting the performance and service life of the stator 33 and the fixing cover 32. The heat-insulating plate 52 is fixedly connected to the mounting shell 31.

[0027] Further, such as Figure 5 and Figure 6 As shown, a same fixed cylinder 43 is provided on the outside of a number of No. 1 fan blades 42. When the connecting seat 41 drives the number of No. 1 fan blades 42 to rotate, the fixed cylinder 43 also rotates accordingly. The interior of the fixed cylinder 43 is fixedly connected to the number of No. 1 fan blades 42. A number of No. 2 fan blades 44 are equidistantly fixed on the circumferential side of the outer wall of the fixed cylinder 43. The No. 2 fan blades 44 are inclined. When the fixed cylinder 43 rotates, the airflow is guided in the direction of the heat conduction cylinder 1 and the heating component 2 through the No. 2 fan blades 44, thereby taking away the heat from the outside of the heating component 2 to form hot air. This improves the heating efficiency while avoiding excessive surface temperature of the heating component 2.

[0028] Further, such as Figure 5 As shown, the heat conducting plate 51 and the heat insulating plate 52 are specifically wavy in shape. When the wind blown out by the blowing assembly 4 passes through the inside of the heat conducting tube 1 and the heat conducting plate 51 and the heat insulating plate 52, the wavy surface guides the airflow to collide back and forth between the heat insulating plate 52 and the adjacent heat insulating plate 52. Such multiple collisions can increase the contact opportunities between the airflow and the heat insulating plate 52, thereby further improving the thermal efficiency.

[0029] Further, such as Figure 3 , Figure 5 and Figure 6 As shown, a heat-conducting ring 6 is fixedly provided on the circumferential side of the outside of the heat-conducting tube 1, and the positions of the heat-conducting ring 6 and the heating component 2 are staggered. The heat of the heating component 2 is conducted through the heat-conducting tube 1 and the blowing component 4. When the wind blown by the blowing component 4 passes through the circumferential side of the heat-conducting tube 1 and takes away the heat dissipated by the heating component 2, it then collides with the heat-conducting ring 6, thereby forcing it to contact with the heat-conducting ring 6 and take away the heat on the heat-conducting ring 6, thereby improving the heating efficiency. After contacting the heat-conducting ring 6, it continues to flow forward through the circumferential side of the outside of the heat-conducting ring 6.

[0030] Example 2 The integrated hot air output device provided in Example 1 is further optimized. Specifically,Figure 1 and Figure 3 As shown, it includes a heat-conducting cylinder 1, which is used to be installed inside devices such as hair dryers or clothes dryers. The heat-conducting cylinder 1 is made of stainless steel or ceramic. Stainless steel such as SUS304, aluminum alloy 6063; ceramic: such as alumina; having both mechanical strength and heat conductivity. An electric heating component 2 is provided on the outside of the heat-conducting cylinder 1, and an installation shell 31 is provided inside the heat-conducting cylinder 1. A fixed cover 32 is fixedly provided at the rear end of the installation shell 31, and a stator 33 is fixedly provided inside the installation shell 31. A rotor is provided inside the stator 33, and a rotating shaft 34 is provided inside the rotor. After being powered on, the stator 33 drives the rotor and the rotating shaft 34 to rotate. A blowing component 4 is provided in front of the circumferential side of the rotating shaft 34. The blowing component 4 is used to generate wind through the rotation of the rotating shaft 34. The wind contacts the surfaces of the electric heating component 2 and the heat-conducting cylinder 1 to take away their heat, forming hot air, which can be used for drying clothes, blowing hair, etc.

[0031] Further, as Figure 1 and Figure 3 shown, the electric heating component 2 includes a flexible circuit board, which is fixed to the outside of the heat-conducting cylinder 1. Heating wires are embedded on the flexible circuit board. The heating wires are arranged in a serpentine path on the surface of the flexible circuit board to increase the contact area. The flexible circuit board is electrically connected to the heating wires. Both ends of the heating wires are connected to the copper electrodes on the flexible circuit board by silver paste printing or micro spot welding to form a closed loop. After being powered on, heat energy is generated through the resistance heating effect. A protective glaze layer 23 covers the outer surfaces of the flexible circuit board and the heating wires.

[0032] Further, as Figure 2 and Figure 3 shown, the blowing component 4 includes a connecting seat 41 fixed to the circumferential side of the rotating shaft 34. When the rotating shaft 34 rotates, the connecting seat 41 also rotates accordingly. A plurality of first fan blades 42 are equidistantly and fixedly provided on the circumferential side of the connecting seat 41. The first fan blades 42 are inclined. When the connecting seat 41 rotates, the plurality of first fan blades 42 rotate around the connecting seat 41. The inclined first fan blades 42 attract the wind on one side to the other side. The wind flow passes through the heat-conducting cylinder 1 and the electric heating component 2 and contacts their surfaces to take away the heat, forming hot air.

[0033] Further, as Figure 5 shown, a heat-conducting connection component 5 is provided between the heat-conducting cylinder 1 and the installation shell 31. The heat-conducting connection component 5 is used to increase the contact area with the wind, thereby improving the heating efficiency, and is also used to support the installation shell 31.

[0034] Further, as Figure 3 and Figure 5As shown, the heat-conducting connection component 5 includes a plurality of heat-conducting plates 51 equidistantly fixed to the inner wall of the heat-conducting tube 1. The heat-conducting plates 51 are made of the same heat-conducting material as the heat-conducting tube 1. When the heat-conducting tube 1 conducts heat, it transfers the heat to the heat-conducting plates 51, causing the heat-conducting plates 51 to generate heat. The heat is gathered between the plurality of heat-conducting plates 51. The wind blown out by the blowing component 4 passes through the heat-conducting plates 51, takes away the heat thereof, increases the contact area with the wind, and thus improves the thermal efficiency. A heat-insulating plate 52 is fixedly provided on one side of the heat-conducting plate 51 close to the mounting shell 31. The heat-insulating plate 52 is a non-heat-conducting material, and a ceramic-based material may be used to reduce the heat conducted to the mounting shell 31, the stator 33 and the rotor, and prevent high temperature from affecting the performance and service life of the stator 33 and the fixing cover 32. The heat-insulating plate 52 is fixedly connected to the mounting shell 31.

[0035] Further, such as Figure 5 and Figure 6 As shown, a same fixed cylinder 43 is provided on the outside of a number of No. 1 fan blades 42. When the connecting seat 41 drives the number of No. 1 fan blades 42 to rotate, the fixed cylinder 43 also rotates accordingly. The interior of the fixed cylinder 43 is fixedly connected to the number of No. 1 fan blades 42. A number of No. 2 fan blades 44 are equidistantly fixed on the circumferential side of the outer wall of the fixed cylinder 43. The No. 2 fan blades 44 are inclined. When the fixed cylinder 43 rotates, the airflow is guided in the direction of the heat conduction cylinder 1 and the heating component 2 through the No. 2 fan blades 44, thereby taking away the heat from the outside of the heating component 2 to form hot air. This improves the heating efficiency while avoiding excessive surface temperature of the heating component 2.

[0036] Further, such as Figure 5 As shown, the heat conducting plate 51 and the heat insulating plate 52 are specifically wavy in shape. When the wind blown out by the blowing assembly 4 passes through the inside of the heat conducting tube 1 and the heat conducting plate 51 and the heat insulating plate 52, the wavy surface guides the airflow to collide back and forth between the heat insulating plate 52 and the adjacent heat insulating plate 52. Such multiple collisions can increase the contact opportunities between the airflow and the heat insulating plate 52, thereby further improving the thermal efficiency.

[0037] Further, such as Figure 3 , Figure 5 and Figure 6 As shown, a heat-conducting ring 6 is fixedly provided on the circumferential side of the outside of the heat-conducting tube 1, and the positions of the heat-conducting ring 6 and the heating component 2 are staggered. The heat of the heating component 2 is conducted through the heat-conducting tube 1 and the blowing component 4. When the wind blown by the blowing component 4 passes through the circumferential side of the heat-conducting tube 1 and takes away the heat dissipated by the heating component 2, it then collides with the heat-conducting ring 6, thereby forcing it to contact with the heat-conducting ring 6 and take away the heat on the heat-conducting ring 6, thereby improving the heating efficiency. After contacting the heat-conducting ring 6, it continues to flow forward through the circumferential side of the outside of the heat-conducting ring 6.

[0038] The use process of the integrated hot air output device provided by the present invention is as follows: When hot air needs to be output, the heating component 2 needs to be started to make it heat up: Start the heating component 2 in Embodiment 1, and connect the two contacts 11 to the positive and negative poles of the power supply through wires respectively, so as to energize the heating circuit 22 to generate heat; Start the heating component 2 in Embodiment 2, energize the flexible circuit board, and make the heating wire generate heat energy through the resistance heating effect; The heat energy generated by the heating component 2 is conducted through the heat conduction cylinder 1, and the heat is transmitted to the heat conduction plate 51 and the heat conduction ring 6. At the same time, after the stator 33 is energized, the stator 33 drives the rotating shaft 34 to rotate through the rotor, so that the connecting seat 41, the first fan blade 42 on the connecting seat 41, the fixed cylinder 43 and the second fan blade 44 rotate. The wind blown by the first fan blade 42 passes through the inside of the heat conduction cylinder 1 to take away the heat inside the heat conduction cylinder 1. The hot air passes through the heat conduction plate 51 and makes the air flow collide back and forth between the heat conduction plates 51 through its wavy surface, thereby increasing the contact area and heating efficiency, and making the efficiency of generating hot air higher; The wind blown by the second fan blade 44 passes through the outside of the heat conduction cylinder 1 and the heating component 2 to take away the heat on its surface, and at the same time collides with the heat conduction ring 6 to take away the wind on the surface of the heat conduction ring 6, improving the thermal efficiency; The wind inside the heat conduction cylinder 1 and the wind outside the heat conduction cylinder 1 gather and mix towards the middle through the shape inside the equipment such as a hair dryer or a dryer after leaving the heat conduction cylinder 1, and are blown out through the air outlet.
