The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0051] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0052] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0053] See appendix Figures 1 to 11 This utility model proposes a towel heating bucket, which includes a bucket body 100, an air outlet mechanism 7, and an air outlet plate 6. The bucket body 100 has an air chamber 101 and a placement chamber 102. The air outlet plate 6 is installed inside the bucket body 100 and separates the air chamber 101 and the placement chamber 102. Multiple ventilation holes 600 are formed on the air outlet plate 6, connecting the air chamber 101 and the placement chamber 102. The air outlet mechanism 7 draws air from outside the bucket body 100 and, after heating, blows it into the air chamber 101. The placement chamber 102 is used to hang towels.

[0054] Among them, the blowing direction G of the air outlet mechanism 7 forms an angle with the vertical direction, or as shown in the attached figure. Figure 5 The blowing direction G of the air outlet mechanism 7 shown is parallel to the horizontal direction. In other words, the air outlet mechanism 7 is a horizontal or inclined air outlet, which allows the airflow entering the air cavity 101 to have a larger distribution area in the lateral direction. Because the air outlet mechanism 7 blows air into the air cavity 101, the air pressure in the air cavity 101 is greater than the air pressure in the placement cavity 102. Therefore, the airflow blown into the air cavity 101 will rise into the placement cavity 102, thereby blowing the towel. The area of ​​the towel exposed to the air is larger than when the air outlet mechanism 7 blows air directly onto the towel, and the heat distribution in the placement cavity 102 is more uniform, resulting in better drying and heating effects for the towel.

[0055] In some embodiments, the air outlet plate 6 includes a plurality of recesses 601 and a plurality of protrusions 602, all extending in a first direction X, which is aligned with the width direction of the base 2. The recesses 601 and protrusions 602 are alternately distributed and connected in a second direction Y, which is aligned with the length direction of the base 2. The first direction X and the second direction Y are perpendicular to each other. The first direction X and the second direction Y are as shown in the attached figure. Figure 7As shown. Ultimately, the air outlet plate 6 is designed with at least a partial wave-like structure. The crest of the wave-like structure is the protrusion 602, and the trough of the wave-like structure is the recess 601. This design allows a portion of the airflow in the air cavity 101 to flow and diffuse along the extension direction of the recess 601, that is, to diffuse along the recess 601 in the first direction X, which facilitates the expansion of the air outlet area of ​​the air outlet plate 6.

[0056] Among them, as attached Figure 7 As shown, multiple ventilation holes 600 are provided on each recess 601 and protrusion 602, and a wave-shaped air outlet plate 6 is used to disperse the rising airflow. If the air outlet plate 6 is flat, the rising airflow may be in the form of a direct jet, resulting in a limited increase in the air-receiving area of ​​the towel. In this embodiment, the wave-shaped air outlet plate 6 changes the height position of each ventilation hole 600 and changes the jet angle of the rising airflow passing through the ventilation holes 600, so that the jets at different positions overlap and shear each other in space, thereby forming a uniformly distributed airflow in the placement cavity 102, which greatly increases the air-receiving area of ​​the towel, that is, the drying and heating effect of the towel is better.

[0057] Specifically, the first direction X is perpendicular to the blowing direction G of the air outlet mechanism 7, and the second direction Y is parallel to the blowing direction G of the air outlet mechanism 7, and both the first direction X and the second direction Y are horizontal. That is, the air outlet plate 6 is a horizontally arranged plate, and the air outlet plate 6 is basically parallel to the blowing direction G of the air outlet mechanism 7, so as to make the airflow that flows and diffuses along the recess 601 diffuse to both sides more uniformly.

[0058] In some embodiments, as shown in the appendix Figure 6 The ventilation holes 600 on the recessed portion 601 are located at the lowest point of the recessed portion 601, and the ventilation holes 600 on the protruding portion 602 are located at the highest point of the protruding portion 602, thus creating a height difference between the ventilation holes 600. The multiple ventilation holes 600 on the recessed portion 601 and the multiple ventilation holes 600 on the protruding portion 602 are evenly distributed at equal intervals in the first direction X. Taking an adjacent recessed portion 601 and a protruding portion 602 as an example, the multiple ventilation holes 600 on the recessed portion 601 and the multiple ventilation holes 600 on the protruding portion 602 are also staggered in the first direction X, thus causing them to stagger in the second direction Y, ultimately resulting in a uniform distribution of the multiple ventilation holes 600 on the wavy air outlet plate 6. In addition, the wave-shaped structure of the air outlet plate 6 is used to generate a pressure difference distribution on its surface airflow, forming local vortices on the side of the recessed portion 601 and the protruding portion 602 facing the air cavity 101. This flow-around effect increases the dispersion of the airflow after passing through the vent 600.

[0059] In some embodiments, as shown in the appendix Figure 6 and7 As shown, the ventilation holes 600 are designed to be wider in the middle and narrower at both sides, for example, the ventilation holes 600 are diamond-shaped. The ventilation holes 600 on the protrusions 602 are located close to or extend to the two adjacent recesses 601 at their two ends. The ventilation holes 600 on the protrusions 602 are higher in the middle and lower on both sides, while the ventilation holes 600 on the recesses 601 are lower in the middle and higher on both sides, so that each ventilation hole 600 itself has a height difference. When the airflow enters the placement cavity 102 through the diamond-shaped ventilation holes 600, it forms a jet. The jet has an angle, and the jets between adjacent ventilation holes 600 intersect and collide.

[0060] In some embodiments, as shown in the appendix Figure 8 and 9 As shown, the air cavity 101 includes a first cavity 1011 and a second cavity 1012 distributed in the horizontal direction. The air outlet mechanism 7 is located between the first cavity 1011 and the second cavity 1012, and the air outlet mechanism 7 has two opposing air outlets 711. The two air outlets 711 are respectively connected to the first cavity 1011 and the second cavity 1012. The air outlet mechanism 7 blows air into the first cavity 1011 and the second cavity 1012 through the two air outlets 711, thereby reducing the airflow intensity at each air outlet 711 and further expanding the air outlet area of ​​the air outlet plate 6.

[0061] Specifically, referring to 10 and 11, the air outlet mechanism 7 includes a housing 71, a blower 72, and an air guide 73. The housing 71 is installed in the barrel 100, and a working chamber 710 is provided inside the housing 71. The housing 71 has an air inlet 712 communicating with the working chamber 710 and two air outlets 711. The air inlet 712 communicates with the outside. The blower 72 and the air guide 73 are both located inside the working chamber 710. The blower 72 draws air from the air inlet 712 and blows the air along the first direction X to the air guide 73 after heating the air. The air guide 73 includes two connected air guide sections 731, which extend obliquely towards the two air outlets 711 respectively, for dividing the airflow blown by the blower 72 into two uniform parts and guiding them to the two air outlets 711 respectively.

[0062] In order to ensure that the airflow from the two air outlets 711 is in the same straight line direction, both air guides 731 are arc-shaped, and the end of the air guide 731 near the air outlet 711 is set roughly along the second direction Y, so that the airflow from the two air outlets 711 is parallel to each other or in the same straight line, that is, both air outlets 711 emit air along the second direction Y.

[0063] In some embodiments, as shown in the appendix Figure 9As shown, the air cavity 101 is formed by a bottom wall 1014, two first inner walls 1015, and two second inner walls 1016. The two first inner walls 1015 are respectively arranged opposite to the two air outlets 711, that is, the two first inner walls 1015 are opposite to each other in the second direction Y, and the two second inner walls 1016 are opposite to each other in the first direction X. The first inner wall 1015 and the bottom wall 1014 have a smooth arc transition, and the second inner wall 1016 and the bottom wall 1014 also have a smooth arc transition. At the same time, the first inner wall 1015 and its two adjacent second inner walls 1016 also have a smooth arc transition.

[0064] Among them, part of the airflow blown out from the air outlet 711 rises directly and passes through the ventilation hole 600 during the flow process, while another part of the airflow directly hits the first inner wall 1015 and then disperses to the surrounding areas along the first inner wall 1015, so that part of the airflow flows to the second inner wall 1016 and passes through the ventilation hole 600 near the second inner wall 1016, thereby expanding the air outlet area of ​​the entire air outlet plate 6.

[0065] In some embodiments, such as Figure 4 and Figure 8 As shown, the air cavity 101 also includes a third cavity 1013, which connects the first cavity 1011 and the second cavity 1012. The air outlet plate 6 includes a first wave portion 61, a second wave portion 62, and a connecting plate 63. The first wave portion 61 is located above the first cavity 1011, and the second wave portion 62 is located above the second cavity 1012. The first wave portion 61 and the second wave portion 62 are connected to two opposite sides of the connecting plate 63, that is, the connecting plate 63 is located between the first wave portion 61 and the second wave portion 62, and the connecting plate 63 is located above the air outlet mechanism 7 and the third cavity 1013. The first wave portion 61 and the second wave portion 62 each include several recesses 601 and several protrusions 602. The connecting plate 63 only has multiple ventilation holes 600 above the area of ​​the third cavity 1013 that is not covered by the air outlet mechanism 7.

[0066] Specifically, the third cavity 1013 is used to converge the airflow returning from the second inner wall 1016. A vent 600 is opened on the connecting plate 63 so that the returning airflow passes through the vent 600 on the connecting plate 63, thereby further expanding the air outlet area and air outlet efficiency of the air outlet plate 6.

[0067] In some embodiments, see Appendix Figure 1 and 2The bucket body 100 includes a frame 1, a base 2, a flexible cover 3, a support structure 4, and at least two hanging rods 5. The aforementioned air cavity 101 is located on the base 2, the air outlet mechanism 7 is detachably mounted on the base 2, and the air outlet plate 6 is mounted above the air outlet mechanism 7. The cover 3 is disposed between the frame 1 and the base 2, forming the aforementioned placement cavity 102 with the base 2 and the frame 1. The support structure 4 is installed between the frame 1 and the base 2, and the support structure 4 can be folded, allowing the frame 1 and the base 2 to move closer or further apart. When the support structure 4 is folded, the cover 3 flexibly folds or stacks, resulting in a smaller folded volume for easier storage. The hanging rods 5 are fixedly or movably mounted on the frame 1 and located within the placement cavity 102, with two of the hanging rods 5 positioned above the first cavity 1011 and the second cavity 1012, respectively. Towels can be hung on the hanging rods 5. The air in the placement chamber 102 is more active above the first chamber 1011 and the second chamber 1012, and the two hanging rods 5 place the towels placed on them directly in the active airflow zone.

The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
