Description

Technical Field

[0001] This invention relates to the field of liquid heating technology, and more particularly to a heater and its control method, as well as a bathroom fixture. Background Technology

[0002] Most bathroom heaters use heating elements for heating, and generally employ heat conduction as the heat transfer method. This means that the heating element directly heats the water, or the heating element itself uses a stainless steel tube as its outer shell, transferring heat to the outer shell through heat conduction to heat the water. However, this method can cause the heating element to melt at high temperatures during use, resulting in the water coming into direct contact with the circuit and potentially causing electric shock. This poses a certain safety hazard to users. Summary of the Invention

[0066] Most bathroom heaters use heating elements for heating, and generally employ heat conduction as the heat transfer method. This means that the heating element directly heats the water, or the heating element itself uses a stainless steel tube as its outer shell, transferring heat to the outer shell through heat conduction to heat the water. However, this method can cause the heating element to melt at high temperatures during use, resulting in the water coming into direct contact with the circuit and potentially causing electric shock. This poses a certain safety hazard to users.

[0067] To address the aforementioned problems, the present invention provides a heater and its control method, as well as a bathroom fixture. Figures 1 to 7 This is a specific embodiment of the heater provided by the present invention. Figure 8 A schematic diagram of a structure of an embodiment of the bathroom device provided by the present invention; Figures 9 to 10 A schematic flowchart of the heater control method provided by the present invention.

[0068] Please see Figures 1 to 3 The heater 100 includes a main body 1 and a heating component 2. The main body 1 has a spaced water flow cavity 11 and a protective cavity 12. The heating component 2 is installed in the protective cavity 12. The heating component 2 can heat the water flow in the water flow cavity 11. The heating component 2 includes a mounting part 21 and a heating element 22 uniformly wound around the mounting part 21.

[0069] In the technical solution provided by this invention, since the heating component 2 is installed inside the protective cavity 12, the heating component 2 can heat the water flow in the water flow cavity 11, thus isolating the heating component 2 from the water flow and achieving water-electricity separation, resulting in high safety performance. The heating component 2 includes a mounting part 21 and a heating element 22 disposed on the mounting part 21, which fixes the heating element and ensures that the heat generated by the heating element 22 is evenly radiated to the water flow cavity 11, resulting in good heating effect, improved user experience, and avoidance of localized overheating of the heating element 22, which could lead to safety hazards.

[0070] Specifically, the mounting part 21 includes a first glass tube 211, and the heating element 22 is connected to the outer wall of the first glass tube 211. This arrangement provides good heat conduction and saves costs.

[0071] It should be noted that in other embodiments, the mounting part 21 may also include a ceramic rod, a glass rod, etc., but this application does not limit it in this respect.

[0072] Specifically, the heating component 22 includes carbon fiber filaments, which are fixed by the mounting portion to fix the shape of the carbon fiber filaments. In addition, when carbon atoms in the carbon fiber filaments mounted on the surface of the mounting portion 21 are excited by electrons in the current, the electrons in the carbon atoms undergo energy level transitions and vibrate at a frequency of 4 to 20 micrometers. The electron vibration generates heat, which is propagated by thermal radiation in the form of electromagnetic waves. The electrothermal conversion rate is high, and the service life of the heater 100 is greatly improved.

[0073] Furthermore, the carbon fiber filaments are wound around the mounting part 21, so that the heat generated by the carbon fiber filaments is evenly radiated to the water flow cavity 11, resulting in good heating effect, improving the user experience, and avoiding the problem of localized excessive heat and temperature of the carbon fiber filaments, which could lead to safety hazards.

[0074] Specifically, refer to Figure 2The main body 1 includes an outer shell 13 and a metal inner shell 14 disposed inside the outer shell 13. The outer shell 13 and the metal inner shell 14 are sealed together, forming a water flow cavity 11 between them. A protective cavity 12 is formed inside the metal inner shell 14. This arrangement allows the heat generated by the heating element 22 to be better conducted to the metal inner shell 14, improving heat conduction efficiency. Furthermore, when the heating element 22 includes carbon fiber filaments, the metal inner shell 14 immediately absorbs most of the electromagnetic waves generated by the carbon fiber filaments and converts them into heat energy. According to the second law of thermodynamics, heat can only be transferred spontaneously from a high-temperature object to a low-temperature object. The heat energy on the metal inner shell 14 will be transferred to the water, producing a heating effect.

[0075] Furthermore, the inner metal shell 14 and / or the outer shell 13 are made of stainless steel, which improves the service life of the heater 100 due to the strong corrosion resistance of stainless steel.

[0076] It should be noted that, in other embodiments, the material of the inner metal shell 14 and / or the outer shell 13 may also include iron, aluminum, copper, or magnesium-aluminum alloy, etc., and this application does not specifically limit this. Furthermore, the shape of the inner and outer metal shells is not limited, as long as the water-electricity separation effect is achieved. In the embodiments of this application, the inner metal shell is cylindrical; of course, in other embodiments, the shape of the inner and outer metal shells can be selected as needed.

[0077] In addition, the material of the outer shell 13 may also include stainless steel, iron, aluminum, copper or magnesium-aluminum alloy, etc. Specifically, in the embodiments of this application, the material of the outer shell 13 is stainless steel, which improves the service life of the outer shell 13. In addition, the outer shell 13 and the metal inner shell 14 can be set separately and fixed by welding, or they can be integrally formed. Specifically, this application does not limit this.

[0078] Reference Figure 2 and Figure 4 The heating component 2 also includes a second glass tube 23 disposed in the protective cavity 12. The mounting part 21 is sealed and installed in the second glass tube 23. With this arrangement, the heating component 22 is sealed and protected by the second glass tube 23, preventing water from contacting the heating component 22, which is safe and reliable and improves the service life.

[0079] Furthermore, the mounting part 21 includes a first glass tube 211, the outer wall of which is connected to the heating element 22. The first glass tube 211 and the second glass tube 23 are coaxially arranged. This arrangement avoids direct contact between the heating element 22 and the second glass tube 23, which could lead to uneven heating and damage to the second glass tube 23.

[0080] Specifically, the interior of the second glass tube 23 is vacuum-sealed, protecting the heating element 22. Furthermore, when the heating element 22 includes carbon fiber filaments, the carbon atoms in the carbon fiber filaments wound around the mounting portion 21 undergo energy level transitions after being excited by electrons in the current, resulting in vibrations with a frequency of 4–20 micrometers. This electron vibration generates heat, which propagates as electromagnetic waves. As shown by the formula v = c / n, the propagation speed of electromagnetic waves is negatively correlated with the propagation medium. In a vacuum, the refractive index of electromagnetic waves is 1, so refraction is negligible, minimizing energy loss and resulting in good performance.

[0081] Reference Figure 4 At least one end of the second glass tube 23 is open. The heating assembly 2 also includes a connector 24 corresponding to the opening. The connector 24 is used to seal the opening, preventing water from entering the second glass tube 23 and preventing water from entering the circuit. This design serves as a second layer of protection for the water-electricity separation of the heater 100. The connector 24 is used for mounting the mounting part 21, with one end electrically connected to the heating assembly 22 and the other end electrically connected to an external power source. This configuration allows for the installation of the mounting part 21, resulting in a simple structure and easy installation.

[0082] Furthermore, the connector 24 is made of ceramic. Since ceramic is a high-temperature resistant material, it prevents the ceramic connector 24 from overheating due to the heat from the heating element 22. In addition, ceramic is less prone to breakage than glass, thus increasing its service life. Furthermore, since the ceramic terminal also functions as the mounting part 21, it effectively isolates the heat conducted through the mounting part 21.

[0083] It should be noted that the connector 24 includes a connector terminal. Of course, in other embodiments, the connector 24 can be selected as needed, and this application does not limit it.

[0084] Reference Figure 4 The cross-section of the connector 24 is larger than the cross-section of the second glass tube 23. This arrangement prevents the second glass tube 23 from colliding and breaking during placement, thus extending the service life of the heater 100.

[0085] In order to fix the heating component 22 to the mounting part 21, specifically, in the embodiments of this application, both ends of the heating component 22 are fixed to the mounting part 21 by wrapping metal wire a. This arrangement achieves the fixation of the heating component 22 and is simple to operate.

[0086] In addition, the heating component can be directly electrically connected to the connector. Specifically, in the embodiments of this application, the metal wire a is electrically connected to one end of the corresponding connector 24. This configuration makes operation simple.

[0087] For ease of installation of the mounting part 21, refer to Figure 2 and Figure 5 The main body 1 is also provided with at least one mounting port 18, which is connected to the protective cavity 12. The heater 100 also includes at least one end cover 3, which is used for mounting the connector 24. The at least one end cover 3 is arranged to cover the at least one mounting port 18. This arrangement makes the structure simple and makes the installation of the mounting part 21 easy.

[0088] Furthermore, referring to Figure 2 The connector 24 is connected to the end cap 3 via a snap-fit ​​structure 4. The snap-fit ​​structure 4 includes a snap-fit ​​protrusion 41 and a snap-fit ​​groove 42 that matches the snap-fit ​​protrusion 41. One of the snap-fit ​​protrusion 41 and the snap-fit ​​groove 42 is located on the connector 24, and the other is located on the end cap 3. With this arrangement, the snap-fit ​​between the connector 24 and the end cap 3 is achieved through the matching of the snap-fit ​​protrusion 41 and the snap-fit ​​groove 42, which makes disassembly and assembly convenient and improves installation efficiency.

[0089] It should be noted that in other embodiments, the connection between the connector 24 and the end cap 3 can also be fixed by screws. Since fixing by screws is prior art, this application will not elaborate on it here.

[0090] In addition, there are various ways to connect and fix the end cap 3 to the main body 1. For example, in one embodiment, the end cap 3 is connected to the stainless steel shell by screws. In other embodiments, the surface of the main body 1 has a closed thin-walled feature, and the end cap 3 is connected to the boss feature with threaded holes on the thin-walled feature by screws.

[0091] To better protect the heating component 2, the protective cavity 12 is filled with an insulating medium, which achieves water and electricity separation, ensuring safety and reliability.

[0092] It should be noted that there are various types of insulating media, such as helium, neon, argon, krypton, or xenon. Specifically, in the embodiments of this application, the insulating media includes air and / or oil. Of course, in other embodiments, the insulating media can be selected as needed, and this application does not limit it.

[0093] Furthermore, in the technical solution of this invention, the insulating medium inside the protective cavity is selected as air. The electromagnetic waves generated by thermal radiation need to be refracted once by the air medium and once by the glass medium. Since the refractive index of air and quartz for electromagnetic waves is extremely low, their refraction can be ignored. Therefore, the moment the electromagnetic waves generated by the carbon fiber are emitted, the stainless steel inner shell immediately absorbs most of the electromagnetic waves and converts them into heat energy. According to the second law of thermodynamics, heat can only be transferred spontaneously from a high-temperature object to a low-temperature object. The heat energy on the metal inner shell will be transferred to the water, producing a heating effect. Since air and the second glass tube carry almost no heat generated by thermal radiation, the thermal efficiency is high.

[0094] Specifically, refer to Figure 2 The main body 1 is also provided with a water inlet 15, which is connected to the water flow cavity 11. The water inlet 15 is arranged facing downwards, which facilitates installation.

[0095] Reference Figure 2 and Figure 7 The main body 1 is also provided with a water inlet 15 and a water outlet 16, both of which are connected to the water flow cavity 11. A connecting pipe 5 extends outward from the main body 1 corresponding to the water inlet 15 and / or the water outlet 16. The end of the connecting pipe 5 has an annular outward flange 51 protruding from its outer side wall. The heater 100 also includes a connecting cylinder 6 corresponding to the connecting pipe 5. One end of the connecting cylinder 6 is used to screw into an external pipeline. The inner wall surface of the other end of the connecting cylinder 6 is stepped to form a contact surface 61. The connecting cylinder 6 is sleeved on the connecting pipe 5, and the contact surface 61 and the annular outward flange 51 are sealed against the end face of the main body 1. This arrangement allows the main body 1 to be connected to the external pipeline through the connecting cylinder 6, which facilitates maintenance. When the connection between the connecting cylinder 6 and the external pipeline and / or the main body 1 is damaged, the connecting cylinder 6 can be directly replaced, saving costs.

[0096] It should be noted that the connecting cylinder can be set as a flange nut. Of course, in other embodiments, the specific setting of the connecting cylinder can be selected as needed. The position and shape of the water inlet 15 and the water outlet 16 are not limited, and the specific settings can be adjusted appropriately as needed.

[0097] Furthermore, referring to Figure 6 The connecting cylinder 6 includes a first pipe section 62 and two arc-shaped enclosure plates 631. The first pipe section 62 is screwed to the external pipe. The two arc-shaped enclosure plates 631 enclose to form a second pipe section 63. One end of the second pipe section 63 is screwed to the first pipe section 62, and the other end of the second pipe section 63 is sleeved on the connecting pipe 5. The abutment surface 61 is formed on the second pipe section 63. With this configuration, the second pipe section 63 is enclosed by the two arc-shaped enclosure plates 631. When assembling the second pipe section 63 with the connecting pipe 5, the two arc-shaped enclosure plates 631 can be placed on both sides of the connecting pipe 5, and then the two arc-shaped enclosure plates 631 can be fastened together to form the second pipe section 63. The abutment surface 61 and the annular outward flange 51 are sealed and abut against the end face of the main body 1. Then, one end of the second pipe section 63 is screwed to the first pipe section 62. The installation is convenient and the operation is simple.

[0098] It should be noted that the two arc-shaped enclosure plates 631 are fixed together by screws. Of course, in other embodiments, the two arc-shaped enclosure plates 631 can also be connected by a snap-fit ​​structure. Specifically, this application does not limit the way the two arc-shaped enclosure plates 631 are connected and fixed together.

[0099] To prevent water leakage, an installation gap is formed between the end face of the first pipe section 62 facing the main body 1 and the end face of the annular outward flange 51 facing away from the main body 1. The heater 100 also includes a sealing ring 7, which is clamped in the installation gap. The installation gap is sealed by the sealing ring 7 to prevent water leakage during use, ensuring safety and reliability and improving the user experience.

[0100] Specifically, refer to Figures 1 to 3 The heater 100 also includes a water pressure switch 8 and / or a temperature switch 9, and a controller. The water pressure switch 8 is installed on the main body 1 and detects the water pressure in the water flow chamber 11. The temperature switch 9 is installed on the main body 1 and detects the temperature of the water inside the water flow chamber 11. Since the controller is electrically connected to the water pressure switch 8 and / or the temperature switch 9 and the heating component 2, the controller controls the operation of the heating component 2 based on the water pressure signal obtained from the water pressure switch 8 and / or the temperature signal obtained from the temperature switch 9, ensuring safety and reliability. This prevents the heating component 2 from drying out due to lack of water in the water flow chamber 11, and also ensures that the water in the water flow chamber 11 is at a suitable temperature, improving the user experience.

[0101] Reference Figure 1The main body 1 has an installation area, and the water pressure switch 8 and / or the temperature switch 9 are both located in the installation area. The heater 100 also includes a waterproof cover 10, which is located in the installation area and is configured to cover the water pressure switch 8 and / or the temperature switch 9. This configuration provides waterproof protection for the water pressure switch 8 and / or the temperature switch 9, ensuring safety and reliability.

[0102] Specifically, in the embodiments of this application, the waterproof cover 10 is fixed to the main body 1 by screws. Of course, in other embodiments, the waterproof cover 10 can also be fastened by a snap-fit ​​structure. Specifically, this application does not limit the fixing method of the waterproof cover 10.

[0103] It should be noted that the waterproof cover 10 is also equipped with a power indicator light and wire inlet / outlet holes, which facilitates observation of whether the power supply is working properly and facilitates the wiring.

[0104] Furthermore, the main body 1 extends upward to provide a water-blocking platform 17, which extends circumferentially along the installation area and is sealed to the waterproof cover 10. This arrangement prevents water from directly entering from the lower end of the waterproof cover 10 due to the obstruction of the water-blocking platform 17, resulting in better waterproofing.

[0105] Specifically, the working principle of the heater is as follows:

[0106] An external electrical control box or power control box supplies power to the heater 100. Firstly, a water pressure switch 8 detects whether the pressure is sufficient. When there is air in the water flow chamber 11 (air density is less than water density), the water pressure switch 8 will not open. When the pressure in the water flow chamber 11 reaches the set pressure, the water pressure switch 8 opens, connecting the power supply and the heating element 2, allowing the heating element 2 to heat the water in the water flow chamber 11 and preventing the heater 100 from drying out and being damaged. Secondly, a temperature switch 9 detects that the temperature exceeds the preset maximum temperature, disconnecting the power supply and the heating element 2. When the temperature drops to the preset minimum temperature, the power supply and the heating element 2 reconnect, allowing the heating element 2 to heat the water in the water flow chamber 11, preventing burns to the user and damage to the heater 100 due to excessive heat. This meets the requirements for constant temperature compensation heating.

[0107] Reference Figure 1 and Figure 8The bathroom fixture 1000 provided by the present invention includes a water storage section 200 and a heater 100. The water storage section 200 has a water storage tank 2001. The heater 100 includes the heater 100 described above. The specific structure of the heater 100 refers to the above embodiments. The heater 100 is installed in the water storage section 200 to deliver heated water into the water storage tank 2001. Since the bathroom fixture 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by all the technical solutions of all the above embodiments, which will not be described in detail here.

[0108] The heater 100 includes a water flow chamber 11 and a protective chamber 12 spaced apart. A heating assembly 2 is provided in the protective chamber 12. (Refer to...) Figure 9 The control method for the heater 100 provided in this application includes the following steps:

[0109] Step S10: After the actual water pressure parameters in the water flow cavity 11 meet the preset conditions, obtain the actual water temperature parameters in the water flow cavity 11.

[0110] Step S20: When the actual water temperature parameter is greater than the first preset temperature, control the heating component 2 to turn off;

[0111] Step S30: When the actual water temperature parameter is less than the second preset temperature, control the heating component 2 to turn on, wherein the second preset temperature is less than the first preset temperature.

[0112] In the above steps, after the actual water pressure parameter in the water flow cavity 11 meets the preset conditions, the actual water temperature parameter in the water flow cavity 11 is obtained. When the actual water temperature parameter is greater than the first preset temperature, the heating component 2 is controlled to turn off. When the actual water temperature parameter is less than the second preset temperature, the heating component 2 is controlled to turn on. The second preset temperature is less than the first preset temperature. In this way, the heater is controlled to work according to the actual water pressure parameter and the actual water temperature parameter. This is intelligent, safe and reliable, so that the heater 100 meets the constant temperature compensation heating requirement and the water heated by the heater 100 is always at a suitable temperature, which meets the user's needs and improves the user experience.

[0113] Specifically, refer to Figure 10 Before obtaining the actual water temperature parameters inside the water flow cavity 11, the method further includes:

[0114] Step S01: Obtain the actual water pressure parameters inside the water flow cavity 11;

[0115] Step S02: When the actual water pressure parameter is greater than the preset pressure, the actual water pressure parameter in the water flow chamber 11 meets the preset condition.

[0116] Step S03: When the actual water pressure parameter is less than the preset pressure, control the heating component 2 to turn off.

[0117] In the above steps, the actual water pressure parameter in the water flow cavity 11 is obtained. When the actual water pressure parameter is greater than the preset pressure, the actual water pressure parameter in the water flow cavity 11 meets the preset condition. When the actual water pressure parameter is less than the preset pressure, the heating component 2 is controlled to turn off. In this way, the problem of dry burning due to insufficient water in the water flow cavity is avoided.

[0118] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
