Description

Technical Field

[0001] This utility model relates to the field of instant heating device technology, and in particular to an exhaust-type anti-expansion instant heating device. Background Technology

[0002] The instant heating system in a smart toilet is the core component that enables instant hot water washing. It rapidly heats the water flow, ensuring users have access to hot water at a comfortable temperature immediately, thus enhancing the user experience and improving energy efficiency. The instant heating system mainly consists of a heating element, a water flow sensor, a temperature sensor, a control unit, and water flow pipes.

[0003] When the user activates the rinsing function, the water flow sensor detects the water flow signal, and the control unit immediately activates the heating element. The water is rapidly heated as it passes through the heating element, and the temperature sensor monitors the water temperature in real time, feeding the data back to the control unit. The control unit automatically adjusts the heating power according to the set temperature target to ensure the water temperature remains constant.

[0004] However, in low-temperature environments, such as cold regions or countries, water may freeze inside the pipes of the instant heating device. Because water expands when it freezes, this creates significant pressure inside the pipes. If this pressure cannot be released in time, the pipes may rupture or be damaged due to excessive stress. This problem not only affects the normal operation of the smart toilet but may also lead to equipment malfunction and increased maintenance costs. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention provides a venting-type anti-expansion and cracking instant heating device, which can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] According to one aspect of the present invention, it includes: an instant heating device body, wherein one end of the instant heating device body is provided with a water inlet pipe and the other end is provided with a water outlet pipe, a water flow pipe is provided between the water inlet pipe and the water outlet pipe to allow water to flow through, a heating pipe is inserted into the water flow pipe, and a pressure relief component is also included. The pressure relief component is detachably covered on the opening of the water flow pipe, and one end of the pressure relief component extends toward the heating pipe and is provided with an elastically deformable protrusion. A cavity is formed in the protrusion, and one end of the cavity is connected to the outside air.

[0008] Furthermore, the top of the protrusion is arc-shaped, and the cross-section of the protrusion is semi-elliptical.

[0009] Furthermore, the pressure relief component is made of silicone.

[0010] Furthermore, it also includes a cover plate, which is detachably installed on the pressure relief component, and the cover plate is provided with a pressure relief hole, which is connected to the cavity.

[0011] Furthermore, the cover plate is made of stainless steel.

[0012] Furthermore, it also includes a heat sink plate, which is detachably installed over the opening of the water flow pipe, and one end of the heat sink plate extends toward the outer circumference of the water flow pipe and is provided with an mounting plate, one end of which is connected to the thyristor; one end of the heat sink plate is provided with a through hole, and the protrusion passes through the through hole.

[0013] Furthermore, a sealing ring is fitted between the opening of the water flow pipe and the heat dissipation plate.

[0014] Furthermore, the opening of the water pipe is provided with an installation groove for installing a sealing ring.

[0015] Furthermore, several screws are installed between the heat sink, pressure relief components, and cover plate and the water flow pipe.

[0016] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0017] Firstly, when pressure is generated inside the water pipe due to the expansion of ice, the pressure acts on the protrusion of the pressure relief component. Under pressure, the protrusion undergoes elastic deformation, and the top of the protrusion compresses towards the cavity, causing the volume of the cavity to decrease or the shape to change. Since one end of the cavity is connected to the outside air, the internal pressure is released through gas exchange between the cavity and the external environment, thereby reducing the pressure peak inside the pipe and preventing it from bursting. After the ice melts, the elastic material of the protrusion causes it to automatically restore its shape.

[0018] Secondly, by setting up a heat sink, the heat conduction effect of the flowing water is used to actively dissipate heat from the thyristor and the surrounding high-temperature area, effectively reducing the operating temperature of the thyristor and avoiding performance degradation or device damage caused by long-term high temperature.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0027] like Figures 1 to 5 As shown, this solution provides a venting-type anti-expansion and crack-prevention instant heating device.

[0028] Please see Figures 1 to 5The device includes: an instant heating device body 1, with an inlet pipe 11 at one end and an outlet pipe 12 at the other end; a water flow pipe 14 between the inlet pipe 11 and the outlet pipe 12 for water flow; a heating pipe 15 inserted inside the water flow pipe 14; and a pressure relief component 4, which is detachably installed over the opening 141 of the water flow pipe 14. One end of the pressure relief component 4 extends towards the heating pipe 15 and has an elastically deformable protrusion 41. A cavity 42 is formed within the protrusion 41, and one end of the cavity 42 is connected to the outside air. The cavity 42 inside the protrusion 41 is connected to the outside air, and pressure is released through volume change of the cavity 42 during deformation, avoiding direct damage to the water flow pipe 14. Specifically, the top of the protrusion 41 is arc-shaped, and the cross-section of the protrusion 41 is semi-elliptical. The semi-elliptical cross-section and arc-shaped top design make it easier for the protrusion 41 to undergo uniform deformation under pressure. The pressure relief component 4 is made of silicone. The protrusion 41 is made of silicone, which has high elasticity and flexibility, allowing it to deform quickly when the pressure inside the pipe increases, releasing pressure promptly and preventing the water pipe 14 from cracking due to ice expansion or overheated steam. It also includes a cover plate 5, which is detachably mounted on the pressure relief component 4 and has a pressure relief hole 51 that communicates with the cavity 42. The cover plate 5 is made of stainless steel. The cover plate 5 is used to fix the pressure relief component 4, improving the stability of the device.

[0029] When pressure is generated inside the water pipe 14 due to ice expansion, the pressure acts on the protrusion 41 of the pressure relief component 4. The silicone protrusion 41 undergoes elastic deformation under pressure, with its tip compressing towards the cavity 42, causing a decrease in the volume or a change in shape of the cavity 42. Since one end of the cavity 42 is connected to the outside air, the pressure relief hole 51 of the cover plate 5 is directly connected to the cavity 42 of the protrusion 41, forming an outlet path for pressure release. When the protrusion 41 deforms, the gas inside the cavity 42 is discharged to the outside through the pressure relief hole 51. The internal pressure is released through gas exchange between the cavity 42 and the external environment, thereby reducing the pressure peak inside the pipe and preventing bursting. After the ice melts, the elastic material of the protrusion 41 causes it to automatically return to its original shape.

[0030] Please see Figures 1 to 5 The system also includes a heat sink 3, which is made of copper sheet. The heat sink 3 is detachably mounted on the opening 141 of the water flow pipe 14, and one end of the heat sink 3 extends towards the outer periphery of the water flow pipe 14 with a mounting plate 31. One end of the mounting plate 31 is connected to the thyristor 13. One end of the heat sink 3 has a through hole 32, through which a protrusion 41 passes. By setting up the heat sink 3, the heat conduction effect of the flowing water is used to actively dissipate heat from the thyristor 13 and the surrounding high-temperature area, effectively reducing the operating temperature of the thyristor 13 and avoiding performance degradation or device damage caused by long-term high temperature.

[0031] Please see Figures 1 to 3A sealing ring 2 is fitted between the opening 141 of the water flow pipe 14 and the heat dissipation plate 3. The sealing ring 2 fills the gap between the water flow pipe 14 and the heat dissipation plate 3, preventing water or steam from leaking out of the gap and improving the airtightness of the water flow pipe 14. Specifically, the opening 141 of the water flow pipe 14 is provided with a mounting groove 142 for installing the sealing ring 2. Several screws 6 are fitted between the heat dissipation plate 3, the pressure relief component 4, and the cover plate 5 and the water flow pipe 14 for easy disassembly and assembly.
