[0012] The third guide surface is at least partially located on the third sub-plate, and the outer edges of the first sub-plate, the second sub-plate, and the third sub-plate are located on the same plane.

[0013] In one embodiment, the side panel further includes a fourth sub-panel located between the first sub-panel and the second sub-panel and connected to the wall of the drying tank. The fourth sub-panel is detachably connected to both the first sub-panel and the second sub-panel, and the first sub-panel, the second sub-panel, and the fourth sub-panel together form the air outlet.

[0014] In one embodiment, the hand dryer further includes a drain pipe located inside the housing. A drain outlet is provided at the bottom of the drying tank. A water storage cavity is formed inside the housing. The drain outlet is connected to the water storage cavity through the drain pipe so that water flowing into the drain outlet enters the water storage cavity.

[0015] The bottom panel has a U-shaped cross-section, and the wall of the water storage cavity is located on the bottom panel.

[0016] In one embodiment, the hand dryer further includes a filter screen located inside the housing and near the bottom panel, the bottom panel having an air inlet near the filter screen so that air entering the air inlet can flow through the filter screen.

[0035] Please see Figures 1 to 3 This utility model provides a water-guiding hand dryer 100, which includes a housing 10 with a drying groove 20 for inserting the user's hand. The drying groove 20 extends through the housing 10 along its length and forms air outlets 21 on both sides of the housing 10. The housing 10 includes a front panel 11, a rear panel 12, and a side panel 13, which are connected to the front panel 11 and the rear panel 12 respectively. The drying groove 20 is located between the front panel 11 and the rear panel 12, and the air outlets 21 are located on the side panel 13. In use, the front panel 11 faces the user, and the rear panel 12 is fixedly mounted on the wall.

[0036] The side panel 13 is recessed inward to form a first guide surface 131 and a second guide surface 132. The first guide surface 131 is located near the front panel 11, and the second guide surface 132 is located near the rear panel 12. The first guide surface 131 and the second guide surface 132 are connected along the width direction of the side panel 13 and enclose a guide cavity 14. The guide cavity 14 extends along the height direction of the hand dryer 100, and along the width direction of the hand dryer 100, the diameter of the guide cavity 14 gradually expands towards the outside of the housing 10.

[0037] It is understood that by setting the first guide surface 131 and the second guide surface 132, the water dripping on the side panel 13 is guided to flow from high to low along the extension direction of the guide cavity 14. The diameter of the guide cavity 14 is gradually widened so that the first guide surface 131 and the second guide surface 132 can prevent water from being blown directly by the air outlet 21 and splashing onto the front or back of the hand dryer 100, so as to prevent the user standing in front of the hand dryer 100 from getting wet or the wall behind it from getting wet.

[0038] Furthermore, a third guide surface 133 is formed on the side panel 13. The third guide surface 133 is fan-shaped and located at the bottom of the side panel 13, connecting to both the first guide surface 131 and the second guide surface 132 along the height direction of the hand dryer 100. Along the height direction of the hand dryer 100, the third guide surface 133 is inclined away from the hand dryer 100. This arrangement guides the water flowing down from the third guide surface 133 to travel as far as possible from the hand dryer 100, allowing the water to be blown away along the extension direction of the third guide surface 133, preventing direct splashing onto the user.

[0039] In this embodiment, the first guide surface 131, the second guide surface 132 and the third guide surface 133 are interconnected and arranged in an arc shape.

[0040] Not limited to this, in other embodiments, the first guide surface 131, the second guide surface 132 and the third guide surface 133 may also be configured as planes.

[0041] In one embodiment, the side panel 13 includes a first partition 134 and a second partition 135. The first partition 134 is connected to the front panel 11, and the second partition 135 is connected to the rear panel 12. The air outlet 21 is located between the first partition 134 and the second partition 135. The first guide surface 131 is at least partially located on the first partition 134, and the second guide surface 132 is at least partially located on the second partition 135. The first partition 134 and the front panel 11 are detachably connected by means of snap-fit ​​or bolt connection, and the second partition 135 and the side panel 13 are integrally connected.

[0042] In this embodiment, a portion of the area of ​​the first guide surface 131 near the front panel 11 is located on the first partition plate 134, and a portion of the area of ​​the second guide surface 132 near the rear panel 12 is located on the second partition plate 135.

[0043] Not limited to this, in other embodiments, the first guide surface 131 is entirely located on the first partition plate 134, the second guide surface 132 is entirely located on the second partition plate 135, and the outer surface of the side panel 13 is formed by splicing the first guide surface 131 and the second guide surface 132. That is to say, the side panel 13 is formed only by splicing the first partition plate 134 and the second partition plate 135.

[0044] In one embodiment, the housing 10 further includes a bottom panel 15, which is located at the bottom of the housing 10 and is connected to the front panel 11, the rear panel 12, and the side panel 13. The side panel 13 further includes a third sub-plate 136, which is located at the bottom of the side panel 13 and connected to the bottom panel 15. The third sub-plate 136 is detachably connected to the first sub-plate 134 and the second sub-plate 135, specifically by snap-fit ​​or bolt connection. The third guide surface 133 is outwardly flared. The bottom panel 15 is integrally connected to the rear panel 12 and detachably connected to the front panel 11 by snap-fit ​​or bolt connection.

[0045] The third guide surface 133 is at least partially located on the third sub-plate 136, and the outer edges of the first sub-plate 134, the second sub-plate 135, and the third sub-plate 136 are located on the same plane.

[0046] In one embodiment, the side panel 13 further includes a fourth sub-panel 137, which is located between the first sub-panel 134 and the second sub-panel 135 and connected to the wall of the drying tank 20. The fourth sub-panel 137 is detachably connected to the first sub-panel 134 and the second sub-panel 135 by means of snap-fit ​​or bolt connection, etc. The first sub-panel 134, the second sub-panel 135 and the fourth sub-panel 137 together form an air outlet 21. Specifically, the fourth sub-panel 137 is integrally connected to the wall of the drying tank 20.

[0047] like Figure 4 As shown, the side panel 13 further includes a fifth sub-plate 138, which is located in the middle of the side panel 13 and is detachably connected to the first sub-plate 134, the second sub-plate 135, the third sub-plate 136 and the fourth sub-plate 137 by means of snap-fit ​​or bolt connection, which facilitates manufacturing and assembly.

[0048] like Figure 5 As shown, in one embodiment, the hand dryer 100 further includes a drain pipe 30 located inside the housing 10. The bottom of the drying tank 20 is provided with a drain outlet 22. The housing 10 has a water storage cavity 40 inside. The drain outlet 22 is connected to the water storage cavity 40 through the drain pipe 30 so that the water flowing into the drain outlet 22 enters the water storage cavity 40.

[0049] The bottom panel 15 has a U-shaped cross-section, and the wall of the water storage cavity 40 is located on the bottom panel 15. That is, the bottom panel 15 is arc-shaped, and thus, the wall of the water storage cavity 40 is also partially arc-shaped. Compared with the existing square-shaped water storage cavity, this structural design can reduce the impact of water on the inside of the water storage cavity 40.

[0050] like Figure 3 and Figure 6As shown, in one embodiment, the hand dryer 100 further includes a filter 50, which is located inside the housing 10 and near the bottom panel 15. The bottom panel 15 has multiple air inlets 151 near the filter 50, arranged at regular intervals to allow air entering the air inlets to be filtered after passing through the filter 50. The bottom panel 15 has a split structure, with the portion of the bottom panel 15 containing the air inlets 151 integrally connected to the rear panel 12.

[0051] In one embodiment, along the height direction of the hand dryer 100, the wall of the drying trough 20 is inclined toward the front panel 11. That is, viewed from the side panel 13, the shape of the drying trough 20 is approximately U-shaped, and at the upper part of the drying trough 20, the inner wall of the drying trough 20 is inclined toward the front panel 11.

[0052] In one embodiment, the hand dryer 100 further includes a baffle (not shown), which is detachably mounted on the side panel 13 by means of snap-fit ​​or bolt connection. The baffle is adapted to the side panel 13 and can block the air outlet 21. The baffle has a through groove that communicates with the drying chamber 20 to balance the air pressure inside and outside the drying chamber 20, ensuring the stability of airflow within the drying chamber 20. The through groove has a strip-shaped structure and extends along the height direction of the hand dryer 100. During installation, the baffle can be installed or not, depending on the requirements.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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.

[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the patent protection scope of this utility model should be determined by the appended claims.
