More and more users are beginning to try using heaters in places with water or damp environments, such as bathrooms, to obtain a warm experience during bathing and other activities.

[0003] However, existing heaters are generally not designed with effective water-resistant structures. Their internal heating elements, as the core components, are directly or indirectly exposed to the external environment, making them highly susceptible to water contact when used in wet environments such as bathrooms. Once water comes into contact with the heating elements, it can not only cause short circuits and damage, affecting the heater's lifespan, but more seriously, it can lead to electrical leaks and other safety hazards, posing a significant threat to the user's personal safety.

[0004] Therefore, how to design a reasonable water-blocking and waterproof structure for heaters to meet the needs of use in water environments such as bathrooms, and effectively prevent water from coming into contact with the heating element, has become a key issue that heater manufacturers urgently need to solve. This is not only related to the market competitiveness of the product, but also closely related to the safety of users. Utility Model Content

[0006] A double waterproof heater structure designed for this purpose includes a housing having a first opening and a second opening.

[0007] The housing is provided with an airflow volute, which has an air outlet communicating with the first opening and an air inlet communicating with the second opening.

[0008] A heating element is installed inside the airflow volute.

[0009] A first water-blocking element is provided between the heating element and the air outlet;

[0010] A second water-blocking element is provided at the air outlet.

[0012] The first water-blocking element includes a first fixing member and a plurality of first water-blocking plates fixedly connected to the first fixing member;

[0013] The first fixing member is fixedly connected to the airflow volute.

[0014] Several first water-blocking plates are arranged in a front-to-back direction.

[0015] Preferably, the air outlet is located at the lower front of the first water-blocking element;

[0016] The second water-blocking element includes a second fixing member and a plurality of second water-blocking plates fixedly connected to the second fixing member;

[0017] The second fixing member is fixedly connected to the airflow volute.

[0018] Several second water-blocking plates are arranged in a vertical direction.

[0019] Preferably, the airflow volute is provided with a guide slope extending downward to the air outlet, and the guide slope is located below the second water baffle.

[0020] Preferably, a drainage channel is provided between the lower surface of the airflow volute and the inner bottom wall of the shell;

[0021] The drainage channel is interconnected with the first opening and the second opening.

[0022] Preferably, the first opening is located at the junction of the front surface and the lower surface of the housing;

[0023] The second opening is located on the rear surface of the housing.

[0024] Preferably, the second opening is disposed on the housing on either the left or right side of the airflow volute.

[0025] The air inlet is located on the upper side wall of the airflow volute.

[0029] Preferably, the air guide grille is provided with connecting parts on the left and right sides, and the connecting parts are rotatably connected to the airflow volute.

[0030] Compared with the prior art, the heater structure of this utility model has many significant advantages:

[0031] In terms of water-resistant performance, by placing a first water-blocking element between the heating element and the air outlet, water that may seep in from the air outlet can be effectively prevented from directly contacting the heating element, forming the first waterproof barrier. Simultaneously, a second water-blocking element at the air outlet further intercepts external water from entering the casing, especially preventing water from flowing towards the heating element, thus forming a second line of defense against water. The two water-blocking elements work together to significantly reduce the probability of water contacting the heating element, substantially improving the heater's waterproof safety in wet environments such as bathrooms.

[0032] In terms of safety, by effectively preventing water from coming into contact with the heating element, it can prevent the heating element from being damaged by short circuits due to water ingress, reducing the occurrence of heater malfunctions; more importantly, it reduces the possibility of safety hazards such as electric leakage from the root, effectively ensuring the personal safety of users when using heaters in humid environments.

[0033] Furthermore, the well-designed structure enhances waterproofing without negatively impacting the heater's normal operation. Airflow still enters the air volute through the inlet, is heated by the heating element, and is smoothly expelled from the outlet, ensuring effective heating. Simultaneously, it reduces the likelihood of water damage to the heating element, contributing to a longer lifespan for the heater and improving product reliability and market competitiveness.

[0049] See Figures 1-7 A double waterproof heater structure includes a housing 10, which has a first opening 100 and a second opening 110. An airflow volute 20 is disposed inside the housing 10. The airflow volute 20 has an air outlet 200 communicating with the first opening 100 and an air inlet 220 communicating with the second opening 110. A heating element 30 is disposed inside the airflow volute 20. A first water-blocking element 40 is disposed between the heating element 30 and the air outlet 200. A second water-blocking element 50 is disposed at the air outlet 200.

[0050] Operating principle of the heater: During operation, outside air enters through the second opening on the casing under the action of the fan, and flows into the airflow volute through the air inlet connected to the second opening. At this time, the heating element inside the airflow volute is energized and generates heat, heating the incoming air. The heated air is guided by the airflow volute and gradually moves towards the air outlet, finally being discharged from the casing through the air outlet connected to the first opening, thus heating the surrounding environment.

[0051] The water-blocking principle of the heater: The first water-blocking element is located between the heating element and the air outlet. When water enters the airflow casing through the air outlet, the first water-blocking element blocks it, preventing the water from continuing upwards to contact the heating element. This forms the first line of protection from the front of the heating element, preventing damage due to water ingress. The second water-blocking element is located at the air outlet, directly intercepting any water that may splash towards it, preventing water from entering the airflow casing through the air outlet. This further cuts off the path of water contact with the heating element, forming a second line of protection and effectively improving the heater's safety in humid environments.

[0052] See Figure 3 The first water-blocking element 40 is positioned directly below the heating element 30. The first water-blocking element 40 includes a first fixing member 410 and several first water-blocking plates 420 fixedly connected to the first fixing member 410. The first fixing member 410 is fixedly connected to the airflow volute 20. The several first water-blocking plates 420 are arranged in a front-to-back direction. The first water-blocking element is positioned directly below the heating element, a position that allows it to precisely block water entering the airflow volute from the air outlet and potentially flowing upwards. The first fixing member is fixedly connected to the airflow volute, ensuring the first water-blocking element is securely installed within the airflow volute, preventing displacement due to airflow impact or equipment vibration, and guaranteeing the stability of the water-blocking effect.

[0053] Furthermore, the first water-blocking plate 420 can be configured into an irregular shape, such as a wave shape, as needed. This irregular shape can block water flow more effectively, while simultaneously reducing airflow velocity. Different sizes of fans can be selected for this purpose. Alternatively, the first water-blocking plate 420 can be tilted, which can further enhance the water-blocking effect. Figure 3 As shown, the first water-blocking plate 420 is set perpendicular to the ground. This design aims to block water while ensuring airflow as much as possible.

[0054] See Figure 3The air outlet 200 is located below and in front of the first water-blocking element 40; the second water-blocking element 50 includes a second fixing member 510 and several second water-blocking plates 520 fixedly connected to the second fixing member 510; the second fixing member 510 is fixedly connected to the airflow volute 20; the several second water-blocking plates 520 are arranged vertically. Since the air outlet is located below and in front of the first water-blocking element, external water can more easily seep into the airflow volute from this position, and the second water-blocking element is designed to specifically intercept this water. The second fixing member is fixedly connected to the airflow volute, providing a stable installation foundation for the entire second water-blocking element, ensuring that it will not shift due to airflow impact or vibration during equipment operation, thus guaranteeing the stability of the water-blocking function. The several second water-blocking plates arranged vertically form a multi-layered vertical water-blocking barrier. When water attempts to enter the airflow volute from the air outlet direction, it will be blocked layer by layer by the vertically arranged second water-blocking plates. This structural design effectively intercepts water intrusion from the air outlet, reducing the possibility of water entering the airflow casing and contacting the first water-blocking element or even the heating element. Simultaneously, the vertically arranged second water-blocking plates, while effectively blocking water, do not excessively obstruct the hot airflow from the air outlet, ensuring the heater's normal airflow efficiency. This allows the heater to maintain reliable water-blocking performance while still efficiently heating, further enhancing its safety and practicality in humid environments.

[0055] See Figure 3 The second water-blocking plate is parallel to the ground. This design aims to block water while maximizing airflow. Depending on the specific water-blocking requirements, the second water-blocking plate can be tilted downwards from back to front, thereby maximizing water blocking.

[0056] See Figure 3 The airflow volute 20 is provided with a guide slope 210 extending downward to the air outlet 200, and the guide slope 210 is located below the second water baffle 520. Since the guide slope is located below the second water baffle, when the second water baffle intercepts water, some of the blocked water will flow down along the second water baffle. At this time, the guide slope can receive and guide this flowing water. The downward-extending structural design allows the water to flow naturally along the guide slope to the air outlet and finally be discharged outside the airflow volute, preventing water from accumulating inside the airflow volute.

[0057] See Figure 3 and Figure 4A drainage channel 120 is provided between the lower surface of the airflow volute 20 and the inner bottom wall of the housing 10; the drainage channel 120 is interconnected with the first opening 100 and the second opening 110. Its main function is to effectively drain water entering through the second opening. Because the drainage channel is interconnected with the second opening, water entering the housing through the second opening will flow into the drainage channel. Simultaneously, the drainage channel is also connected to the first opening, allowing water entering the drainage channel to smoothly pass through the channel and exit the housing through the first opening, preventing water entering through the second opening from accumulating inside the housing.

[0058] See Figures 1 to 4 The first opening 100 is located at the junction of the front surface and the lower surface of the housing 10; the second opening 110 is located on the rear surface of the housing 10.

[0059] See Figures 1 to 6 The second opening 110 is located on either the left or right side of the housing 10 of the airflow volute 20; the air inlet 220 is located on the upper side wall of the airflow volute 20. From the perspective of reducing the risk of water ingress, the second opening is located on the side of the housing, which, compared to a location at the bottom of the housing, reduces the possibility of large amounts of water directly entering through the second opening. This is especially important in environments such as bathrooms, reducing the likelihood of water directly entering the second opening due to surface water or splashes. Simultaneously, the air inlet is located on the upper side wall of the airflow volute, creating a spatial misalignment with the second opening on the side of the housing. When a small amount of water enters the housing through the second opening, because the air inlet is positioned higher, the water is less likely to directly enter the air inlet and flow into the airflow volute to contact the heating element, further reducing the threat of water to the heating element. In terms of ensuring air intake efficiency, the placement of the second opening on the side of the casing and the air inlet on the upper side wall of the airflow volute allows external air to enter the casing more smoothly through the second opening and then flow to the air inlet located above. This reduces obstruction to airflow, ensures sufficient air enters the airflow volute, and ensures that the heating element can fully heat the air and maintain the heating effect of the heater.

[0060] See Figure 4 The first opening 100 is provided with an air guide grille 60, and the air guide grille 60 is provided with an air guide port 610, which is interconnected with the first opening 100; the air guide grille 60 is rotatably disposed relative to the housing 10. The air guide port on the air guide grille is interconnected with the first opening, which can guide and regulate the hot airflow discharged from the first opening, so that the hot airflow is discharged in an orderly manner according to the orientation of the air guide port, avoiding the chaotic diffusion of hot airflow at the outlet, improving the directional delivery effect of hot airflow, allowing heat to flow more concentratedly to the target area, and enhancing the heating effect.

[0061] Meanwhile, the air guide grille is rotatable relative to the housing, a design that allows for adjustment of the air vent direction. Users can rotate the air guide grille to change the orientation of the air vent according to their actual heating needs, flexibly adjusting the direction of hot air discharge to meet the heating requirements of different locations, thus improving the flexibility and convenience of using the heater.

[0062] In addition, the air guide grille can also play a role in blocking water to some extent. Its grille structure can block water splashing from the outside towards the first opening, reducing the possibility of water directly entering the casing through the first opening. Together with the second water-blocking element, drainage channel and other structures, it further improves the waterproof safety of the heater.

[0063] Furthermore, the second water-blocking element 50 is disposed directly behind the air guide grille 60.

[0064] Furthermore, the air guide grille 60 is provided with connecting parts 620 on the left and right sides, and the connecting parts 620 are rotatably connected to the airflow volute 20.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
