[0026] In the present invention, various embodiments of the hot air blower according to the present invention are mainly described in combination with a bathroom heater, but the scope of the present invention is not limited thereto, but may include various types of hot air blowers.

[0027] According to one aspect of the utility model, a flow guide assembly for a hot air blower is provided.

[0028] Figure 1 FIG. 1 shows a flow guide assembly 100 for a hot air blower according to some embodiments of the present invention. Figure 1 The bottom plate of the guide assembly 100 is shown separately.

[0029] The air guide assembly 100 may include a housing 110. The housing 110 may define an internal space of the hot air blower. As an example, the housing 110 may include a base plate and a shell. The housing 110 may include a vent 111 and a vent 113. As an example, the vent 111 may be arranged to face the outdoors, and the vent 113 may be arranged to face the indoors.

[0030] The flow guide assembly 100 may include a flow guide wall 120 located in the housing 110 .

[0031] The air guide assembly 100 may include a cover 130. The cover 130 may be at least partially confined in the vent 113. The cover 130 may include a linearly arranged vent portion 131, a vent portion 133, and a connecting portion 132 connecting the vent portion 131 and the vent portion 133. The cover 130, the housing 110, and the air guide wall 120 may be configured to form an air duct capable of flowing between the vent 111 and the vent 130 in the air guide assembly 100.

[0032] The flow guide assembly 100 may include a flow divider 140. The flow divider 140 is inside the housing 110 and is configured to divide the generated air duct.

[0033] By providing linearly arranged ventilation parts 131 and ventilation parts 133 separated from each other and dividing the air duct into two parts by using the diverter 140, the air output of the hot air blower used by the guide assembly 100 can be made more uniform, thereby improving the user experience.

[0034] In some embodiments, the flow divider 140 may include a first end 141 and an opposite second end 143. The first end 141 is disposed at the connection portion 135. The second end 143 extends toward the interior of the flow guide assembly 100.

[0035] By arranging the diverter 140 at the connecting portion 135 that separates the ventilation portion 131 and the ventilation portion 133 of the cover body 130, the diverted air duct can be blown out through the corresponding ventilation portion 131 and the ventilation portion 133 respectively, thereby further promoting the uniformity of the blown airflow.

[0036] The housing 110 may define a position 115 of a wind wheel for use with the housing 110. In some embodiments, the vent 111 and the position 115 may be disposed on the same side of the linear arrangement direction of the housing 130 (eg, Figure 1 on the right side of the image).

[0037] By arranging the position 115 of the wind wheel and the vent 111 on one side of the air guide assembly 100, the length of the air duct is reduced, thereby increasing the efficiency of blowing or ventilation.

[0038] In some embodiments, the flow divider 140 extends in a straight line from a first end 141 to a second end 143 on a side close to the position 115 of the wind wheel.

[0039] By setting the side of the diverter 140 close to the position 115 of the wind wheel to extend in a straight line, it is helpful to reduce the noise generated when blowing and to promote the uniformity of the air flow and flow rate in the direction of the linear arrangement. This is because if an end face extending along an arc is used, the air may be guided to the vents on the other side of the linear arrangement direction, thereby affecting the uniformity of the air outlet.

[0040] In some embodiments, the guide wall 120 may include a portion 125 , which may include an arc shape that at least partially conforms to the shape of an outer edge of a wind wheel used in conjunction therewith.

[0041] By providing a guide wall that is consistent with the outer edge shape of the wind wheel, the efficiency of airflow transmission in the air duct can be improved and the resistance can be reduced.

[0042] Figure 2 FIG. 1 shows an internal view of a guide assembly 100 for a hot air blower according to some embodiments of the present invention. Figure 2 The cover is not shown.

[0043] In some embodiments, the portion of the housing that cooperates with the indoor vent may include a shape that gradually narrows from the inside of the guide assembly toward the indoor vent (not shown), such as Figure 2By setting the guide wall to have a gradually narrower width facing the indoor vent, the resistance of the air duct formed in the guide assembly 100 can be reduced. The guide assembly for the hot air blower according to the utility model can discharge air more evenly.

[0044] According to another aspect of the present invention, a hot air blower is provided.

[0045] Figure 3 FIG. 3 shows a hot air blower 300 according to some embodiments of the present invention. Figure 3 The bottom plate of the hot air blower 300 is shown separately.

[0046] The hot air blower 300 may include a flow guide component, a heating component 310 and a wind wheel 320. The flow guide component may be a combination of the above Figure 1 The deflector assembly 100 is shown in FIG. 1. The heat generating assembly 310 is partially hidden by the cover of the deflector assembly in this view.

[0047] Figure 4 The figures show heat generating components 400 and 450 for a hot air blower according to some embodiments of the present invention.

[0049] In some embodiments, the heating component 400 may further include heat sinks 403 and 404 on both sides of the heating unit 401 along the linear arrangement direction. The heating component 400 may further include heat sinks 404 and 405 on both sides of the heating unit 402 along the linear arrangement direction.

[0050] By arranging heat sinks 403, 404, 405 on both sides of the heating units 401, 402, the heat of the heating units 401, 402 in use can be effectively dissipated, thereby ensuring safe use.

[0051] In some embodiments, the heating component 400 may be integrally formed to facilitate installation in a heat blower.

[0052] A heat blower according to some embodiments may include a heat generating assembly 450. In some embodiments, the heat generating assembly 450 may include heat generating units 451, 452 parallel to each other.

[0053] In some embodiments, the heating component 450 may further include heat sinks 453 and 454 on both sides of the heating unit 451 along the linear arrangement direction. The heating component 450 may further include heat sinks 454 and 455 on both sides of the heating unit 452 along the linear arrangement direction. The heating component 450 may further include a honeycomb heat dissipation structure 456 filled between adjacent heating units 451 and 452 and heat sinks 453, 454 and 455.

[0054] By arranging a uniformly distributed honeycomb heat dissipation structure 456 within the heat generation range of the heat generation units 451 and 452, the heat dissipation effect of the heat generation units 451 and 452 during use can be further promoted, thereby further ensuring the safety of use.

[0055] In some embodiments, the heating component 350 may be integrally formed to facilitate installation in a heat blower.

[0056] Figure 5 A heat generating assembly 510 and a cover 520 for a hot air blower according to some embodiments of the present invention are shown.

[0057] In some embodiments, the heating component 510 can be at least partially confined within the housing 520. Placing the heating component 510 within the housing 520 near the vent of the hot air blower can make the heated air closer to the vent to be blown out, thereby improving the utilization efficiency of the heated air.

[0058] In some embodiments, the cover 520 may include a limiting structure 521 at one end of the linear arrangement direction. The limiting structure 521 may be used to limit the heating component 510 in the linear arrangement direction. As an example, the limiting structure 521 may include a plurality of parallel baffles arranged along the linear arrangement direction.

[0059] In some embodiments, the other end of the cover 520 in the linear arrangement direction may include a limiting structure 523. The limiting structure 521 may be used to limit the heating component 510 in the direction of leaving the cover 520. As an example, the limiting structure 521 may include one or more buckles.

[0060] By providing the limiting structure 521 and the limiting structure 523 , it is easier to install and remove the heating component 510 relative to the cover body 520 .

[0061] In some embodiments, the heating component 510 may be formed in one piece, thereby making it easier to install and remove the heating component 510 relative to the cover body 520 .

[0062] The hot air blower according to the utility model discharges air more evenly.
