[0030] Reference Figure 1-6 This utility model provides:

[0031] A bathroom heater includes a housing 1, in which a fan 2, a heating element 3 and a waterproof air duct assembly 4 are disposed. An air inlet 101 and an air outlet are provided on the housing 1, and an air outlet front shell assembly 5 is provided at the air outlet of the housing 1.

[0032] A fan bracket is provided inside the housing 1, and the fan 2 is fixedly installed inside the housing 1 via the fan bracket. The heating element 3 includes a heating element 31 and a heating element bracket 32, and the heating element 31 is fixedly installed inside the housing 1 via the heating element bracket 32. In this embodiment, two fans 2 are provided. In other embodiments, the implementer can provide an appropriate number of fans 2 as needed.

[0033] The heating element 3 is disposed between the fan 2 and the waterproof air duct assembly 4. The air inlet 101 is disposed on the side of the housing 1 away from the fan 2 and the heating element 3. The air outlet front shell assembly 5 is disposed on the side of the waterproof air duct assembly 4 away from the heating element 3. Specifically, the air inlet 101 is disposed at the bottom of the housing 1, which can prevent water from entering the housing 1 through the air inlet and improve the waterproof performance.

[0034] The waterproof duct assembly 4 includes multiple vertically arranged straight ribs 41, which are bent, forming multiple bent waterproof ducts 42 inside the waterproof duct assembly 4. Specifically, the straight ribs 41 inside the waterproof duct assembly 4 have multiple bends, and the connection point with the front shell assembly 5 of the heating element 3 is a vertical straight rib 41. The function of the straight rib 41 is to ensure that the hot air blown out of the heating element 3 is straight, and the larger windward surface can guide the air to the bend, which is more conducive to the heat dissipation of the heating element 3 and increases the heat output efficiency of the heating element 3. The straight rib 41 at the front end is to ensure that the blown hot air is blown out straight and not crooked. In addition, the waterproof ducts 42 inside the waterproof duct assembly 4 are bent, so that the heating element 3 should not be visible from any direction when looking inward from the hot air outlet, which provides a good waterproof effect.

[0035] The air outlet front housing assembly 5 includes a front grille 51 and an adjustable air outlet grille 52. The adjustable air outlet grille 52 can swing within the front grille 51 to adjust the air outlet direction. The swingable adjustable air outlet grille 52 allows for quick adjustment of the warm air outlet direction, ensuring that the hot air can evenly cover the entire bathroom, further enhancing the user experience.

[0036] Specifically, the air outlet front housing assembly 5 further includes a front housing 53, and the front grille 51 is fixed to the air outlet position of the housing 1 via the front housing 53. The adjustable air outlet grille 52 has a swing shaft 521 on its side, and the front grille 51 has a swing groove 511 that cooperates with the swing shaft 521. The swing shaft 521 is disposed within the swing groove 511 and can rotate within the swing groove 511. When it is necessary to adjust the air outlet direction, the adjustable air outlet grille 52 can be swinged. The adjustable air outlet grille 52 rotates within the swing groove 511 via its swing shaft 521, thereby realizing the swing function of the adjustable air outlet grille 52.

[0037] The housing 1 includes an upper housing 11 and a lower housing 12. A control module 6 is mounted on the upper housing 11. The control module 6 is electrically connected to the fan 2 and the heating element 3. The control module 6 is the control device for the entire bathroom heater, and it is used to automatically control the coordinated operation of each module.

[0038] The distance between the fan 2 and the heating element 3 is greater than 20cm. If they are too close or too far apart, it will greatly affect the heat dissipation effect of the heating element 3, thereby reducing the thermal efficiency of the heater and the overall airflow speed. In addition, the distance between the heating element 3 and the waterproof air duct assembly 4 is 5-50mm. If the distance is too close, the heat dissipation effect of the heating element 3 will be poor. If the distance is too far, it will affect the airflow speed at the air outlet of the whole unit.

[0039] In the specific implementation of this utility model, under the action of the fan 2, external air enters the interior of the outer shell 1 through the air inlet 101 and is sent into the heating component 3 through the fan 2. The heating component 3 heats the air and sends it into the waterproof air duct component 4. The warm air passing through the waterproof air duct component 4 is sent out through the air outlet front shell component 5.

[0040] In some embodiments, a baffle plate 102 is provided inside the housing 1, forming a wind cavity 103 within the housing 1. A fan 2 is located at the outlet of the wind cavity 103, and an air inlet 101 is located at the bottom of the wind cavity 103. In this embodiment, an air inlet duct cover 13 is provided at the upper opening of the wind cavity 103, forming an air inlet duct within the wind cavity 103. The fan 2 is located at the outlet of the air inlet duct. By configuring the wind cavity 103 and forming an air inlet duct, the incoming air can be more concentrated, ensuring wind speed and volume, which helps improve product performance.

[0041] In some embodiments, a bracket 121 and a foot 122 are provided at the bottom of the lower shell 12, and a towel rack 123 is provided at the front end of the lower shell 12. The bracket 121, foot 122, and towel rack 123 can further expand the functionality of this product and improve the user experience.

[0042] The bathroom heater provided by this technical solution has the following advantages:

[0043] 1. Adjustable air vent grille to meet the needs of different consumers and improve user comfort.

[0044] 2. Modular design saves on various costs;
