Description

Technical Field

[0001] This invention relates to the field of bathroom heater technology, specifically to a bathroom heater and its usage method. Background Technology

[0002] Bathroom heaters (bathroom heaters): Integrating three core functions—heating, ventilation, and lighting—they include: Lamp heaters: using infrared quartz bulbs (275W / bulb) for radiant heating, providing instant heat and low energy consumption, but with the problem of "hot head, cold feet," suitable for small spaces ≤4㎡; Fan heaters: using PTC ceramic heating elements as the heat source, with forced convection through a fan for even heating; Dual-flow heaters: combining infrared bulbs and PTC ceramic heating for improved thermal efficiency; Far-infrared heaters: simulating sunlight, releasing far-infrared rays through photocatalytic materials, also offering therapeutic functions.

[0003] A search revealed patent number CN215723533U, entitled "A Bathroom Heater," relating to the field of home appliances. The bathroom heater includes a shell, a first fan, and a heating element. The shell has an air inlet and an air outlet, forming an air duct for airflow. The heating element is located within the air duct near the air outlet and spaced apart from it. The air duct at the air outlet gradually narrows in the airflow direction. This design ensures that even if some airflow passes by the heating element without being fully heated, this lower-temperature airflow can be gathered by the air duct before reaching the air outlet and mixed with the fully heated, higher-temperature airflow, resulting in a uniform temperature of the warm air delivered from the air outlet. This uniform airflow temperature provides a better user experience. However, research and analysis revealed that while the airflow temperature is uniform, the following drawbacks still exist to some extent.

[0004] For example, if the exhaust air cannot be sterilized, a large number of bacteria and organic odor molecules will be released along with the bathroom heater during ventilation, causing pollution to the surrounding environment at the heater's exhaust vent. To solve these technical problems, we have designed a bathroom heater and its usage method. Summary of the Invention

[0015] A method of using a heater for a bathroom, the method comprising the aforementioned heater for a bathroom, and the method further comprising the following steps: Step 1: When the exhaust fan is used to ventilate the bathroom, turn on the exhaust fan and UV-C deep ultraviolet sterilization lamp using the external control terminal of the bathroom heater. The outside air is guided by the exhaust fan and enters the outer shell through the guide slope. Then the air enters the exhaust pipe through the air duct chamber on the right side. The flowing air blows up the sealing valve plate and then discharges the air. Step 2: In summer, when the human body feels hot, when using the blower function of the bathroom heater, use the external control terminal of the bathroom heater to turn on the hot air fan and the embedded AI human sensing radar; the outside air is guided by the hot air fan and enters the outer shell through the guide slope, and then the air is discharged into the air guide hood through the air duct chamber on the left, and then the air passes downward through the ceramic PTC heating block and finally blows out from the gap between the swing plate and the swing notch; Step 3: In winter, when the body feels cold or when taking a bath, use the external control terminal of the bathroom heater to turn on the hot air blower, the embedded AI human-sensing radar, and the ceramic PTC heating block; the outside air is guided by the hot air blower and enters the outer shell through the guide slope, and then the air is discharged into the air guide hood through the air duct chamber on the left.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, through the use of an exhaust component, has the advantage of sterilizing the exhaust air. When the exhaust fan and UV-C deep ultraviolet germicidal lamp are turned on, outside air, guided by the exhaust fan, enters the outer casing through the guide slope. Then, the air enters the exhaust pipe through the right-side air duct chamber. The flowing air blows up the sealing valve plate, causing it to rotate around the support shaft. The flowing air overcomes the resistance of the sealing valve plate and is then discharged. During the air exhaust process, the UV-C deep ultraviolet germicidal lamp stimulates the titanium dioxide nano-coating to generate electron-hole pairs. The holes can oxidize formaldehyde, and the electrons can reduce oxygen molecules to generate superoxide radicals, decomposing organic odor molecules. Furthermore, the UV-C deep ultraviolet germicidal lamp emits 265nm ultraviolet light that destroys the base pair structure of microbial DNA / RNA, blocking the replication of genetic material and causing the microorganisms to lose activity within 0.1-2 seconds.

[0017] 2. This invention, through the use of exhaust components, can block the backflow of odors from the public flue and reduce the rate of odor return in the bathroom; secondly, it avoids the backflow of airflow during windy weather, which could cause the motors of the hot air blower and exhaust fan to overspeed and be damaged, thus extending the service life of the bathroom heater; it can also reduce heat loss through the exhaust pipe, thereby reducing the energy consumption for heating the bathroom in winter.

At this time, the bathroom heater can be used as a lighting fixture.

[0037] When in use, the exhaust fan 48 ventilates the bathroom. The exhaust fan 48 and the UV-C deep ultraviolet germicidal lamp 29 are turned on by the external control terminal of the bathroom heater. The outside air is guided by the exhaust fan 48 and enters the outer casing 1 through the guide slope 37. Then the air enters the exhaust pipe 25 through the air duct chamber 8 on the right side. The flowing air blows the sealing valve plate 26 up (the sealing valve plate 26 will not come into contact with the barb 24 after being blown by air), causing it to rotate around the support shaft 211. The flowing air is discharged after overcoming the resistance of the sealing valve plate 26. During air exhaust, the UV-C deep ultraviolet germicidal lamp 29 activates the titanium dioxide nano-coating 252 to generate electron-hole pairs. Holes (h⁺) oxidize formaldehyde → CO₂ + H₂O, while electrons (e⁻) reduce oxygen molecules to generate superoxide radicals (·O⁻), decomposing organic odor molecules. The reaction is: HCHO + 2·OH → CO₂ + 2H₂O. Furthermore, the UV-C deep ultraviolet germicidal lamp 29 emits 265nm ultraviolet light that destroys the base pair structure of microbial DNA / RNA (especially thymine dimerization), blocking genetic material replication and causing microorganisms to lose activity within 0.1-2 seconds. The airflow velocity generated by the exhaust fan 48 is controlled at ≤1.5m / s. The microbial exposure time is ≥0.5 seconds, which is beneficial for killing microorganisms. Furthermore, moisture in the air is also discharged through the exhaust pipe 25. The barbed rod 24 prevents birds from nesting inside the exhaust pipe 25. After ventilation, the exhaust fan 48 and UV-C deep ultraviolet germicidal lamp 29 are turned off, and the sealing valve plate 26 resets under its own gravity. The use of the sealing valve plate 26 can block the backflow of odors from the public flue (especially in older communities), reducing the rate of odor return to the bathroom. Secondly, it prevents backflow of airflow during windy weather, which could cause overspeed damage to the motors of the hot air blower 46 and exhaust fan 48, extending the lifespan of the bathroom heater. It also reduces heat loss through the exhaust pipe 25, lowering bathroom heating energy consumption in winter. The sealing valve plate 26 is made of polyetheretherketone (PEEK) resin, which is temperature resistant up to 180℃ and is hydrophobic and scale-resistant.

[0038] In summer, when the body feels hot, using the fan function of the bathroom heater (similar to an electric fan) activates the hot air blower 46 and the embedded AI human-sensing radar 312 via the external control terminal of the bathroom heater. Outside air, guided by the hot air blower 46, enters the outer casing 1 through the guide slope 37, then is discharged into the air guide shroud 43 through the left-side air duct chamber 8, and finally passes downwards through the ceramic PTC heating element 41, ultimately exiting through the gap between the swing plate 33 and the swing notch 314. When a person moves around in the bathroom, the embedded AI human-sensing radar 312 continuously detects the person's position, speed, and trajectory. Based on changes in the person's position, the drive motor 34 rotates forward or backward accordingly, causing the swing plate 33 to rotate forward or backward as well. At this time, the air blown out from the swing notch 314 is directed towards the person, improving comfort.

[0039] In winter, when the human body feels cold or when taking a bath, the external control terminal of the bathroom heater is used to turn on the hot air blower 46, the embedded AI human sensing radar 312, and the ceramic PTC heating block 41. The outside air is guided by the hot air blower 46 and enters the outer shell 1 through the guide slope 37. Then the air is discharged into the air guide cover 43 through the air duct chamber 8 on the left side. Then the air passes downward through the ceramic PTC heating block 41, taking away the heat on the ceramic PTC heating block 41. Finally, hot air is blown out from the gap between the swing plate 33 and the swing notch 314. When a person moves around in the bathroom, the embedded AI human-sensing radar 312 continuously detects the position, speed, and trajectory of the human body. Based on the changes in the human body's position, the drive motor 34 rotates forward or backward accordingly (at this time, the rotation direction of the drive motor 34 is opposite to the aforementioned rotation direction), thereby causing the swing plate 33 to rotate forward or backward accordingly. At this time, the air blown out from the swing gap 314 does not blow directly onto the human body, avoiding excessively high temperatures that could burn the skin or make the skin feel dry. Furthermore, it prevents the flow of hot air during or between showers from accelerating the evaporation of moisture from the human body and carrying away heat (evaporative heat absorption effect). Even if the air is hot, it will feel cool, just like the feeling of getting colder the more a fan blows in summer. Moreover, when a person is showering, their pores open, and direct hot air can easily cause the pores to contract rapidly, which may lead to headaches or trigger joint diseases in the long run.

[0040] When the bathroom heater is running, the lighting strip 316 can be turned on as needed, allowing the heater to function as a light fixture. Furthermore, during operation, the corresponding electronic components on the indicator panel 315 operate, and the results are displayed on the screen 313 for easy monitoring of the heater's status. The hot air blower 46 and exhaust fan 48 can operate simultaneously or independently. The advantages of simultaneous operation include: efficient dehumidification and mold prevention: simultaneous exhaust during heating quickly removes moisture, preventing dampness and mold growth in the bathroom; improved air circulation: convection between hot and exhaust air eliminates stuffiness and provides more even temperature distribution; safety protection: preventing moisture from contacting high-temperature components (such as the ceramic PTC heating element 41), reducing the risk of electrical leakage. The disadvantages of simultaneous operation include: reduced efficiency due to airflow interference; increased energy consumption: simultaneous operation increases power consumption; noise amplification: simultaneous operation may amplify noise levels, affecting comfort. In actual operation, users can choose according to their actual needs; it is not mandatory.

[0041] In summary, the bathroom heater and its usage method solve the problem of the inability to sterilize the exhaust air by using the exhaust component 2. When the bathroom heater is ventilating, a large number of bacteria and organic odor molecules are discharged together, causing pollution to the surrounding environment at the air outlet of the bathroom heater.
