Description

Technical Field

[0001] This utility model relates to the field of bathroom heater technology, and in particular to a touch screen controller for a bathroom heater. Background Technology

[0002] Traditional bathroom heater control panels mostly use mechanical buttons or ordinary touch screens. Prolonged exposure to humid environments can easily lead to moisture seepage, causing short circuits and touch screen malfunctions. While existing technologies incorporate some waterproof designs, such as sealing rings at connections, their complex structures and limited waterproofing effectiveness cannot effectively handle direct water flow or condensation buildup. Therefore, there is an urgent need for a simple, waterproof touch screen controller. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a touchscreen controller for a bathroom heater, which solves the problem of moisture infiltration and improves the safety and lifespan of the touchscreen controller in humid environments.

[0004] Therefore, the technical solution of this utility model is: a touch screen controller for a bathroom heater, including a housing, a touch panel, and a control circuit board, wherein the control circuit board is placed inside the housing, and the touch panel is placed on the front side of the housing, characterized in that: a silicone annular sealing ring is embedded between the touch panel and the housing, and the edges of the touch panel are bent inward to form a water guiding slope; an inverted V-shaped first guide groove is provided below the touch panel, and the two sides of the first guide groove are inclined downward; a longitudinal second guide groove is provided on the side of the housing, and a drain hole is provided in the second guide groove, which is connected to the first guide groove.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the inclination of the two sides of the first guide channel is 5° to 10°, and the end of the first guide channel is connected to the drain hole through a flared mouth.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the radial cross-section of the first guide channel is a V-shaped structure, and the radial cross-section of the second guide channel is a U-shaped structure.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: a nano-hydrophobic coating is sprayed into the first and second guide channels.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: a dustproof net is installed on the outside of the opening of the second guide channel. The dustproof net is made of plastic or stainless steel.

[0009] Based on the above solution and as a preferred embodiment of the above solution: the housing includes a front housing and a rear housing, which are fixedly connected by snap fasteners, and a double-layer silicone sealing ring is provided between the two.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The tempered glass panel features inwardly curved water-guiding surfaces around its perimeter, quickly directing water away from seams. Combined with the elastic compression of the silicone ring seal, this forms the first waterproof barrier, effectively blocking splashing water and preventing water from seeping into the circuit board. The first and second guide channels form a tiered flow system, quickly draining surface water and preventing water from seeping into the housing. Furthermore, a nano-coating is sprayed inside the guide channels, allowing water to slide off quickly and carry away dust, preventing dust accumulation inside the channels. This invention effectively solves the pain points of traditional bathroom heater controllers, such as easy water ingress, easy dust accumulation, and cumbersome maintenance, making it particularly suitable for high-humidity and high-soil bathroom scenarios.

They should not be construed as limiting the specific protection scope of this utility model.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0019] See the attached diagram. The touchscreen controller of the bathroom heater described in this embodiment includes a housing 1, a touch panel 2, and a control circuit board 3. The housing 1 includes a front housing 11 and a rear housing 12, which are fixedly connected by snap-fit, and a double-layer silicone sealing ring is provided between them, namely an inner sealing ring 13 and an outer sealing ring 14. The control circuit board 3 is placed inside the housing 1. The inner sealing ring 13 and the outer sealing ring 14 can simultaneously seal the connection of the housing 1 to prevent moisture from entering the interior of the housing 1 and avoid damage to the control circuit board 3 when exposed to water.

[0020] The front side of the housing 1 is provided with an installation port, the touch panel 2 is installed on the front side of the housing, and a silicone annular sealing ring 4 is embedded between the touch panel 2 and the housing 1, which can effectively seal the seam between the touch panel 2 and the housing 1; the edges of the touch panel 2 are bent inward to form a water guiding slope 21, which can quickly guide the water flow away from the seam and flow along the water guiding slope into the first guide groove.

[0021] The touch panel 2 is formed by hot-pressing a tempered glass panel and a waterproof adhesive layer. The edges are injection-molded and sealed with silicone. The edges of the tempered glass panel are bent inwards to form a water-guiding slope. The surface transmittance is ≥92%, and the hardness is ≥9H. The water-guiding slopes bent inwards around the tempered glass panel quickly guide water away from the seams. Combined with the elastic compression of the silicone annular sealing ring, this forms the first waterproof barrier, effectively blocking splashing water and preventing water from penetrating into the housing.

[0022] The touch panel 2 is provided with an inverted V-shaped first guide groove 5 below it. The two sides of the first guide groove 5 are inclined downwards, and the inclination of the two sides of the groove is 8°. The radial cross section of the first guide groove 5 is a V-shaped structure. The first guide groove 5 is coated with a nano hydrophobic coating, such as fluorocarbon resin or silicon dioxide coating, with a contact angle ≥120°.

[0023] The shell 1 has a longitudinal second guide channel 6 on its side. The radial cross-section of the second guide channel 6 is U-shaped, and the bottom of the second guide channel 6 is open to facilitate water discharge. A drain hole 61 is provided inside the second guide channel 6, and the end of the first guide channel 5 is connected to the drain hole 61 through a flared mouth 51. The second guide channel 6 is coated with a nano-hydrophobic coating to facilitate dust accumulation. At the same time, a dustproof net 62 made of stainless steel can be selectively installed on the outside of the opening of the second guide channel 6.

[0024] The end of the first guide channel connects to the drain hole through a gradually expanding flared opening, forming a continuous drainage path of "guide channel → gradually expanding section → drain hole". At the same time, the first guide channel and the drain hole are designed separately to avoid weakening the overall strength of the shell due to the opening at the end of the channel.

[0025] The first guide channel 5 and the second guide channel 6 form a graded guide system, which can quickly drain surface water and prevent water from seeping into the shell; and the guide channel is sprayed with a nano coating, which allows the water to slide down quickly and carry away dust, preventing dust from accumulating in the guide channel.

[0026] This embodiment effectively solves the pain points of traditional bathroom heater controllers, such as easy water ingress, easy dust accumulation, and cumbersome maintenance, and is especially suitable for bathroom scenarios with high humidity and high dirt.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
