[0001] This utility model relates to the field of household appliance technology, and in particular to a circulating air duct structure for a foot dryer. Background Technology

[0002] A foot dryer is a device specifically designed for quickly drying feet. It is commonly used in public places such as gyms, swimming pools, and bathrooms to help users dry their feet quickly, avoiding the inconvenience and hygiene problems caused by wiping feet with towels or other cloths. It can also effectively reduce the safety hazards caused by obese people or elderly people with limited mobility bending over to dry their feet.

[0003] Existing foot dryers generally include a casing, a fan, and a perforated pedal. The fan is located at the bottom of the casing, with its air outlet above it. The pedal is positioned at the air outlet, and the air generated by the fan blows through the outlet onto the user's feet, thus drying them. However, these foot dryers can only dry the soles of the feet and cannot quickly dry the entire foot.

[0004] Therefore, there is an urgent need for a foot dryer that can dry the user's feet more quickly and thoroughly. Utility Model Content

[0005] The purpose of this invention is to propose a circulating air duct structure for a foot dryer, which can effectively solve the technical problem that existing foot dryers cannot quickly and thoroughly dry the user's feet, thus overcoming the shortcomings of the existing technology.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A circulating air duct structure for a foot dryer includes a housing, a centrifugal fan, and a heating mechanism;

[0008] The housing includes a base and a top cover plate. The top cover plate is installed on the top of the base, and the base and the top cover plate together form the inner cavity of the housing. The top of the top cover plate is provided with an inwardly recessed U-shaped surface. The U-shaped surface has a main air inlet and a hot air outlet, and both the main air inlet and the hot air outlet are connected to the inner cavity. The main air inlet is prominently located in the middle of the U-shaped surface, and the hot air outlet is located on both sides of the U-shaped surface.

[0009] The centrifugal fan is installed in the middle of the inner cavity, with the air inlet of the centrifugal fan facing the main air inlet and the air outlet of the centrifugal fan facing the cavity wall of the inner cavity.

[0010] The heating mechanism is installed on both sides of the inner cavity, and a hot air outlet is provided corresponding to a heating mechanism.

[0011] Preferably, the housing further includes a mounting base located in the inner cavity and symmetrically mounted on both sides of the top of the base;

[0012] A ventilation opening is provided at the center of the bottom of the mounting base, and the ventilation opening is used to accommodate the heating mechanism.

[0013] Preferably, the mounting base is provided with an outwardly protruding arc-shaped air guide plate, and the arc-shaped air guide plate is located on the outside of the heating mechanism;

[0014] The inner bottom wall of the base is U-shaped.

[0015] Preferably, the U-shaped surface is further provided with an auxiliary air inlet, which is located on both sides of the main air inlet and is connected to the inner cavity.

[0016] Preferably, the main air inlet includes a plurality of circumferentially arranged main air inlets, and the main air inlets extend vertically;

[0017] The auxiliary air inlet includes a plurality of auxiliary air inlets arranged in parallel, and the auxiliary air inlets extend horizontally;

[0018] The hot air outlet includes multiple hot air holes arranged in parallel, and the cross-section of the hot air holes in the vertical direction is arc-shaped.

[0019] Preferably, the centrifugal fan is a brushless variable frequency fan.

[0020] Preferably, the heating mechanism is a PTC ceramic heating element.

[0021] The technical solution provided by this utility model can include the following beneficial effects:

[0022] 1. The housing of this solution includes a base and a top cover plate that overlap each other to form an inner cavity. The top of the top cover plate is provided with an inwardly recessed U-shaped surface, and a main air inlet protruding from the U-shaped surface is provided in the middle of the surface. At the same time, hot air outlets are provided on both sides. This allows the air to form a circulating airflow in the housing under the drive of the centrifugal fan. This is beneficial for the drying air blown out from the hot air outlets to be directly blown onto the ankles, insteps and soles of the user standing inside the U-shaped surface, which is more conducive to the rapid evaporation and removal of moisture from the feet.

[0023] 2. Since the airflow can circulate within the structure of this design, the foot soles can be dried quickly through the airflow. Furthermore, the circulating gas allows the drying air blown out from the hot air outlet to re-enter the inner cavity through the main air inlet, be reheated, and then blown out from the hot air outlet again, thereby further improving the drying efficiency of the foot dryer.

[0029] The components include: housing 1, inner cavity 101, base 11, upper cover 12, U-shaped surface 121, main air inlet 122, hot air outlet 123, auxiliary air inlet 124, mounting base 13, ventilation position 131, arc-shaped air guide plate 132, centrifugal fan 2, and heating mechanism 3. Detailed Implementation

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] This technical solution provides a circulating air duct structure for a foot dryer, including a housing 1, a centrifugal fan 2, and a heating mechanism 3;

[0032] The housing 1 includes a base 11 and a top cover 12. The top cover 12 is installed on the top of the base 11, and the base 11 and the top cover 12 together form the inner cavity 101 of the housing 1. The top of the top cover 12 is provided with an inwardly recessed U-shaped surface 121. The U-shaped surface 121 has a main air inlet 122 and a hot air outlet 123. The main air inlet 122 and the hot air outlet 123 are both connected to the inner cavity 101. The main air inlet 122 is protrudingly located in the middle of the U-shaped surface 121, and the hot air outlet 123 is located on both sides of the U-shaped surface 121.

[0033] The centrifugal fan 2 is installed in the middle of the inner cavity 101, and the air inlet of the centrifugal fan 2 faces the main air inlet 122, and the air outlet of the centrifugal fan 2 faces the cavity wall of the inner cavity 101.

[0034] The heating mechanism 3 is installed on both sides of the inner cavity 101, and a hot air outlet 123 is provided corresponding to a heating mechanism 3.

[0035] To address the technical problem that existing foot dryers cannot quickly and thoroughly dry a user's feet, this technical solution proposes a circulating air duct structure for the foot dryer, such as... Figure 1-5 As shown, it includes a housing 1, a centrifugal fan 2, and a heating mechanism 3; wherein, the centrifugal fan 2 is used to guide and pressurize the air, thereby forming a specific airflow in the foot dryer, and the heating mechanism 3 is used to heat the air in order to form a drying air that can better improve the drying speed.

[0036] Specifically, to facilitate quick and thorough drying of the user's feet, this solution optimizes the structure of the foot dryer's casing 1, allowing air to circulate within the casing 1 under the drive of the centrifugal fan 2 (flow direction as shown in the image). Figure 3 (As indicated by the middle arrow). Specifically, the housing 1 includes a base 11 and an upper cover 12 that overlap each other to form an inner cavity 101. The top of the upper cover 12 is provided with an inwardly recessed U-shaped surface 121, and a main air inlet 122 protruding from the U-shaped surface 121 is provided in the middle of the upper cover 12. At the same time, hot air outlets 123 are provided on both sides, so that the drying air blown out by the hot air outlets 123 can be directly blown towards the ankles, insteps and soles of the user standing inside the U-shaped surface 121, which is more conducive to the rapid evaporation and removal of moisture from the feet.

[0037] In addition, since the airflow can circulate under the structure of this solution, the foot soles can be dried quickly through the airflow. Furthermore, the circulating gas can also allow the drying air blown out from the hot air outlet 123 to re-enter the inner cavity 101 through the main air inlet 122, and be reheated before being blown out from the hot air outlet 123 again, thereby further improving the drying efficiency of the foot dryer.

[0038] Furthermore, the housing 1 also includes a mounting base 13, which is located in the inner cavity 101 and is symmetrically mounted on both sides of the top of the base 11.

[0039] A ventilation position 131 is provided at the center of the bottom of the mounting base 13, and the ventilation position 131 is used to accommodate the heating mechanism 3.

[0040] In a preferred embodiment of this technical solution, the housing 1 further includes a mounting base 13 for mounting the heating mechanism 3. The opening of the ventilation position 131 can guide the air into the inner cavity 101 through the main air inlet 122 and then through the heating mechanism 3, thereby effectively heating the air.

[0041] To further explain, the mounting base 13 is provided with an outwardly protruding arc-shaped air guide plate 132, and the arc-shaped air guide plate 132 is located on the outside of the heating mechanism 3;

[0042] The inner bottom wall of the base 11 is U-shaped.

[0043] As a further improvement of the above embodiment, in order to make the air circulation smoother, this solution also adds an arc-shaped air guide plate 132 to the outside of the heating mechanism 3, and sets the inner bottom wall of the base 11 as U-shaped to facilitate the flow of gas.

[0044] Furthermore, the U-shaped surface 121 is also provided with an auxiliary air inlet 124, which is located on both sides of the main air inlet 122 and is connected to the inner cavity 101.

[0045] In another preferred embodiment of this technical solution, auxiliary air inlets 124 are added on both sides of the main air inlet 122, and the location of the auxiliary air inlets 124 can correspond to the position of the user's toes. By adding auxiliary air inlets 124, this solution can effectively enhance the drying efficiency of the foot dryer for the toes, which have many crevices.

[0046] To further explain, the main air inlet 122 includes a plurality of circumferentially arranged main air inlets, and the main air inlets extend vertically;

[0047] The auxiliary air inlet 124 includes a plurality of auxiliary air inlets arranged in parallel, and the auxiliary air inlets extend horizontally.

[0048] The hot air outlet 123 includes a plurality of hot air holes arranged in parallel, and the cross-section of the hot air holes in the vertical direction is arc-shaped.

[0049] This effectively increases the air intake area of ​​the main air inlet 122 and the auxiliary air inlet 124, while also increasing the air outlet area of ​​the hot air outlet 123, which is more conducive to improving the drying efficiency of the foot dryer.

[0050] To further clarify, the centrifugal fan 2 is a brushless variable frequency fan.

[0051] To further clarify, the heating mechanism 3 is a PTC ceramic heating element.
