[0023] In order to make the purpose, technical scheme and advantages of the utility model clearer, the utility model will be described in further detail below in combination with the drawings.

[0024] Referring to Figure 1 and Figure 2 , the utility model discloses a kind of damp-proof structure of wind warm bath heater, including cabinet 1 and air heating device 2.

[0025] The utility model embodiment improves the cabinet 1 inside wind warm bath heater, by reducing the temperature difference between inside bath heater and outside, so that water droplet cannot be generated in the cabinet 1 inside.

[0026] Specifically, the opposite two side walls 11 of the cabinet 1 are respectively provided with air inlet hole 12 and air outlet hole 13 opposite in position, air duct 3 is connected between air inlet hole 12 and air outlet hole 13, and the air heating device 2 is arranged in the air duct 3.

[0027] The cabinet 1 is slidably connected with baffle 4 on the side wall where air inlet hole 12 and air outlet hole 13 are located, the baffle 4 can slide along the plane direction where air inlet hole 12 and air outlet hole 13 are located, and the side wall 11 in the cabinet 1 is further provided with driving motor 5, and the driving motor 5 is connected with the baffle 4 to drive the baffle 4 to slide.

[0028] When the bath heater is used, the fan 21 in the cabinet 1 is started and the heating component 22 is started, and air is sucked from the air inlet hole 12. First, the heating component 22 heats the air, and the hot air flows quickly in the air duct 3 between the air inlet hole 12 and the air outlet hole 13, so that the overall temperature of the air duct 3 rises, thereby the overall temperature of the cabinet 1 rises. Finally, the temperature difference between the overall temperature of the cabinet 1 and the outside temperature is reduced, and then the water droplet cannot be condensed into water droplet in the bath heater. In addition, when the wind warm bath heater is not used, the driving motor 5 drives the baffle 4 to slide to the air inlet hole 12 and the air outlet hole 13 to block, so that the high humidity air outside cannot enter the cabinet 1, and the mouse and ant can be prevented from entering.

[0029] In some embodiments, referring to Figure 2 , the heating component 22 can be composed of a plurality of heating plates 221 arranged in parallel with each other. The air flows through the gap between the heating plates 221, so that the air can be heated uniformly and effectively, and the temperature rising speed of the air duct 3 is effectively accelerated.

[0030] More preferably, the fan 21 is an axial fan. The axial fan is a kind of fan whose air flow direction is the same as the direction of the fan blade shaft. In the embodiment, the fan 21 is parallel to the side wall 11 of the cabinet 1, and the heating plate 221 is perpendicular to the plane in which the side wall 11 of the cabinet 1 is located. The heating plate 221 functions as a guide plate in the air duct 3, and guides the heated air upward along the rotating shaft of the axial fan, effectively avoiding the generation of turbulence. The space is reserved between the air inlet hole 12 and the heating plate 221, and between the heating plate 221 and the fan 21. The air around the heating plate 221 can be fully heated.

[0031] In some embodiments, the side wall 11 of the cabinet 1 is provided with a sliding groove 14 at the top and bottom of the air inlet hole 12 and the air outlet hole 13, and the baffle 4 is slidably connected with the sliding groove 14. The edge of the baffle 4 is embedded in the sliding groove 14 and is slidably connected with the sliding groove 14. Under the drive of the drive motor 5, the baffle 4 smoothly slides along the sliding groove 14 to control whether the baffle 4 blocks the air inlet hole 12 and the air outlet hole 13.

[0032] Preferably, as shown in Figure 1 and Figure 3 The air inlet hole 12 and the air outlet hole 13 are composed of a plurality of first air grooves 15. A dust screen is arranged on the outer side wall 11 of the cabinet 1 to prevent external dust from entering the inside of the cabinet 1, causing a large amount of dust to accumulate on the heating component 22 and the fan 21.

[0033] In some embodiments, the baffle 4 is provided with a second air groove 41 matched with the first air groove 15, and the width of the first air groove 15 is equal to the distance between two adjacent first air grooves 15, and the width of the second air groove 41 is equal to the width of the first air groove 15. Since the drive motor 5 drives the baffle 4 to slide, the baffle 4 at the air inlet hole 12 and the air outlet hole 15 can make the second air groove 41 communicate with the first air groove 15 or be blocked. Therefore, the drive motor 5 only needs to drive the baffle 4 to slide a small amplitude, so as to realize the effect of whether to block the air inlet hole 12 and the air outlet hole 13. The installation space inside the cabinet 1 is effectively saved.

[0034] In some embodiments, the drive motor 5 includes a motor body 51 and an electric push rod 52 capable of stretching and retracting, the electric push rod 52 is connected with the baffle 4, and the motor body 51 is fixed on the side wall 11 of the cabinet 1; the side wall of the air duct 3 is provided with a avoiding groove 31, and the baffle 4 can extend into the avoiding groove 31. The baffle 4 can enter the air duct 3 from the avoiding groove 31, so as to avoid interference between the baffle 4 and the air duct 3 during movement.

[0035] Correspondingly, as shown in Figure 1As shown, the utility model embodiment further provides a kind of wind warm bath heater, including above-mentioned damp-proof structure. Wherein, damp-proof structure includes case 1 and air heating device 2, case 1 is equipped with panel 6, the panel 6 is equipped with illuminating lamp plate 61, display panel 62 and grating 63.

[0036] Specifically, case 1 is further equipped with air duct cylinder, the air duct cylinder has air inlet 18 and the first air outlet 16 and second air outlet 17 of interval arrangement. The first air outlet 16, second air outlet 17 and the setting of air inlet 18 make wind warm bath heater possess two functional modes of heating and ventilation.

[0037] Further, illuminating lamp plate 61 is preferably LED lamp, to provide illumination and adjust the function of light atmosphere in bathroom. Display panel 62 is used to show working condition. The side of panel 6 is equipped with grating 63, and the grating 63 is communicated with the first air outlet 16 and second air outlet 17, and the hot air sent can be sent from the grating 63.

[0038] The above is the preferred embodiment of the utility model, it should be pointed out, for the ordinary skill in the art person of the present technology, without departing from the principle of the utility model, can make a number of improvements and refinements, these improvements and refinements also be considered the protection scope of the utility model.
