Description

Technical Field

[0001] This application relates to the field of water purifier technology, and in particular to a heating module and a water purifier. Background Technology

[0002] Existing thick film heaters typically consist of a metal substrate, an insulating layer, and a thick film resistive layer, and achieve rapid heating by directly heating water flowing over its surface with an electric current.

[0003] In existing technology, the working process of a thick-film heater is as follows: When a user needs hot water, cold water flows over the surface of the heater. The thick-film resistive layer heats up rapidly after being energized and transfers the heat to the flowing water. However, due to the high heating power density of the thick-film heater, rapid heating can easily lead to a sharp rise in local water temperature, generating a large number of bubbles. These bubbles cause water disturbance and generate significant noise during their formation, growth, and detachment. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0024] Existing thick-film heating tubes generate large bubbles during the heating process, and these bubbles produce significant noise when they detach from the heating tube surface or rupture.

[0025] In response to the above problems, such as Figure 1 and Figure 2 As shown, an embodiment of this application provides a heating module 100, mainly used for heating water flowing through a heating pipe 110. The heating module 100 includes a heating pipe 110, a bubble puncture structure 140, a first end cap 120, and a second end cap 130.

[0026] The heating tube 110 includes a heating tube 110 body and a resistive film layer.

[0027] The heating element 110 body is made of stainless steel (such as 304 or 316L) because it has good strength, corrosion resistance, and thermal conductivity. The heating element 110 body serves as the mechanical support and pressure-bearing carrier for the entire heating element. An insulating dielectric layer made of one or more vitreous glazes or ceramic materials is provided on the surface of the heating element 110 body. This insulating dielectric layer serves as electrical insulation and thermal conductivity.

[0028] The resistive film layer is a special paste made of metal oxides (such as oxides of ruthenium, silver, palladium, etc.), glass powder, and organic solvents. This paste can be precisely coated onto the insulating dielectric layer using screen printing technology. When electricity is applied, current passes through this resistive film layer, generating heat.

[0029] The first end cap 120 and the second end cap 130 are respectively connected to the heating tube 110 body, and the resistive film layer covers the outer side of the heating tube 110 body.

[0030] The first end cap 120 is connected to one end of the heating tube 110, and the second end cap 130 is connected to the other end of the heating tube 110. The portions of the first end cap 120 and the second end cap 130 that are in contact with the resistive film layer are conductive. The first end cap 120 and the second end cap 130 are respectively connected to an external power source to supply power to the resistive film layer.

[0031] A bubble-puncturing structure 140 is disposed on the first end cap 120 and / or the second end cap 130, and at least part of the surface of the bubble-puncturing structure 140 protrudes outward. It should be noted that the surface of the outwardly protruding part is a densely distributed micro-protrusion surface or a continuous protrusion surface. When a bubble moves to the micro-protrusion surface or the continuous protrusion surface, the large bubble will be punctured or divided into several small bubbles by the protrusion surface, reducing the shock wave generated when the large bubble bursts, thereby achieving the purpose of reducing the noise level during the heating process.

[0032] In some embodiments, the bubble puncture structure 140 is a cylindrical spring, a ceramic bellows, a metal wire mesh, or a metal needle mesh.

[0033] For example, such as Figure 2 As shown, when the bubble punctures the structure 140, which is a cylindrical spring or a ceramic bellows, its surface is a continuous raised surface. This continuous raised surface forms a structure similar to a cutting blade, which plays the role of cutting large bubbles.

[0034] For example, when the bubble punctures the structure 140, which is a metal wire mesh or metal needle mesh, its surface is a densely covered micro-protrusion surface. This densely covered micro-protrusion surface forms a needle-like structure, which serves to puncture the large bubble.

[0035] In some embodiments, when the bubble puncturing structure 140 is disposed on the first end cap 120, the first end cap 120 includes a first connecting tube 121 and a second connecting tube 122. The first connecting tube 121 is connected to the heating tube 110, and the second connecting tube 122 is connected to the side of the first connecting tube 121 away from the heating tube 110. The bubble puncturing structure 140 is sleeved on the outside of the second connecting tube 122 and fixed by a slot or groove.

[0036] like Figure 2As shown, it can be understood that the bubbles generated during the heating process will move towards the end and gather. By setting the bubble puncture structure 140 in the second connecting tube 122, the bubbles actively move towards the bubble puncture structure 140 and gather, thereby improving the puncture efficiency of large bubbles and reducing the volume and material consumption of the bubble puncture structure 140, thus saving costs.

[0037] In some embodiments, when the bubble puncture structure 140 is disposed on the second end cap 130, the second end cap 130 includes a third connecting tube 131 and a fourth connecting tube 132. The third connecting tube 131 is connected to the heating tube 110, and the fourth connecting tube 132 is connected to the side of the third connecting tube 131 away from the heating tube 110. The bubble puncture structure 140 is sleeved on the outside of the fourth connecting tube 132 and fixed by a slot or groove.

[0038] like Figure 2 As shown, it can be understood that the bubbles generated during the heating process will move towards the end and gather. By setting the bubble puncture structure 140 in the fourth connecting tube 132, the bubbles actively move towards the bubble puncture structure 140 and gather, thereby improving the puncture efficiency of large bubbles and reducing the volume and material consumption of the bubble puncture structure 140, thus saving costs.

[0039] In some embodiments, the heating module 100 further includes a first fixing plate 151 and a first connecting pipe 152.

[0040] like Figure 2 and Figure 3 As shown, the first fixing plate 151 is connected to the end of the second connecting pipe 122 away from the first connecting pipe 121. The first connecting pipe 152 is disposed on the first fixing plate 151 and communicates with the first end cap 120. The heating medium (such as hot oil, steam, or hot water) is introduced into or out of the heating pipe 110 through the first connecting pipe 152 to achieve uniform heating. The first fixing plate 151 supports the second connecting pipe 122 to reduce displacement or deformation of the pipe due to thermal expansion and contraction or pressure changes.

[0041] In some embodiments, the heating module 100 further includes a second fixing plate 161 and a second connecting pipe 162.

[0042] like Figure 1 and Figure 2 As shown, the second fixing plate 161 is connected to the end of the fourth connecting pipe 132 away from the third connecting pipe 131. The second connecting pipe 162 is disposed on the second fixing plate 161 and communicates with the second end cap 130. Heating medium (such as hot oil, steam, or hot water) is introduced into or out of the heating pipe 110 through the first connecting pipe 152 to achieve uniform heating. Furthermore, by connecting the first connecting pipe 152 and the second connecting pipe 162 to external circulation equipment, the heating medium circulates, improving heating efficiency and uniformity.

[0043] The fourth connecting pipe 132 is supported by the second fixing plate 161, which reduces the displacement or deformation of the pipe due to thermal expansion and contraction or pressure changes.

[0044] like Figure 1 and Figure 2 As shown, a first switch 153 is provided on the first fixing plate 151, and a second switch 163 is provided on the second fixing plate 161. The first switch 153 switches the connection and disconnection states of the first connecting tube 121 and the heating tube 110, and the second switch 163 switches the connection and disconnection states of the second connecting tube 122 and the heating tube 110.

[0045] In some embodiments, the heating module 100 further includes a protective sleeve 170.

[0046] like Figure 1 and Figure 3 As shown, the protective sleeve 170 covers the surface of the heating tube 110, the first end cap 120, and the second end cap 130, and the first fixing plate 151 is connected to one end of the protective sleeve 170. This physically isolates the easily damaged resistive film layer from the external environment (especially moisture and corrosive liquids) to prevent it from being oxidized, corroded, or mechanically scratched.

[0047] In some embodiments, such as Figure 3 As shown, the second fixing plate 161 is connected to the other end of the protective sleeve 170. There is a gap between the surface of the protective sleeve 170 and the heating tube 110. The protective sleeve 170 is provided with a water inlet / outlet interface 171. The water inlet / outlet interface 171 is connected to the gap between the protective sleeve 170 and the heating tube 110, so that water flows through the surface of the heating tube to heat the water.

[0048] This application also provides a water purifier, which includes the heating module 100 in any of the above embodiments. Therefore, it has all the beneficial effects of the heating module 100 in any of the above embodiments, which will not be described in detail here.
