Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] The purpose of this invention is to provide an instant heating device to solve the problems existing in the prior art, so that the manual reset thermostat and the automatic reset thermostat can sensitively detect temperature changes, and then accurately control the temperature of the instant heating device through the manual reset thermostat and the automatic reset thermostat.
[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] like Figures 1 to 4As shown, this embodiment provides an instant heating device that can precisely control water temperature. The instant heating device includes a heating channel 2, within which a heating tube 1 is installed. When water flows through the heating channel 2, the cold water is heated by the heating tube 1. A reset thermostat is installed on the outside of the heating channel 2. The reset thermostat includes an automatic reset thermostat 11 and a manual reset thermostat 12. The automatic reset thermostat 11 and the manual reset thermostat 12 determine the heat generated by the heating tube 1 during operation by detecting the temperature of the wall of the heating channel 2, thereby determining the power of the heating tube 1. Therefore, supports are installed on the wall of the heating channel 2. The support 16 forms a protruding platform inside the heating pipe 2. A temperature measuring wall 15 is provided on the opposite side of the support 16. The support 16 is recessed into the interior of the heating channel 2, reducing the diameter of the heating channel 2 and causing the heating pipe 1 to tilt towards the temperature measuring wall 15, ensuring that the heating pipe 1 and the temperature measuring wall 15 are in contact. The temperature control probes provided at the ends of the automatic reset temperature controller 11 and the manual reset temperature controller 12 abut against the outer wall of the temperature measuring wall 15, improving the measurement accuracy of the heat of the heating pipe 1 by the automatic reset temperature controller 11 and the manual reset temperature controller 12 through the temperature measuring wall 15, and improving the safety level of the instant heating device during use.
[0027] To accommodate heating tubes 2 of different diameters, a support frame 17 is provided on the side of the support part 16 facing the inside of the heating channel 2. The support frame 17 fixes the heating tube 1 inside the heating channel 2 to prevent the heating tube 1 from shaking inside the heating channel 2. This further ensures that the heating tube 1 can be in contact with the temperature measuring wall 15. After the ends of the automatic reset temperature controller 11 and the manual reset temperature controller 12 are in contact with the outer side of the temperature measuring wall 15, the temperature change of the heating tube 1 can be detected more accurately through the wall of the heating channel 2, thereby improving the safety performance of the instant heating device.
[0028] To ensure that the heating tube 1 abuts against the temperature measuring wall 15, the side of the temperature measuring wall 15 facing the inner side of the heating channel 2 can be arc-shaped or flat. In this embodiment, the inner side of the temperature measuring wall 15 is flat.
[0029] After the heating tube 1 is inserted into the heating channel 2, one end of the heating tube 1 inside the heating channel 2 is suspended. In order to avoid the instability of the relative position between the heating tube 1 and the temperature measuring wall 15 under different postures of the heating channel 2, the support frame 17 is set with an arc-shaped groove on the side facing the axis of the heating channel 2 that can fit into the heating tube 1, so as to prevent the heating tube 1 from shifting during use.
[0030] An elastic element is also provided on the side of the support frame 17 facing the axis of the heating channel 2. When the size of the heating tube 1 is small and the support frame 17 cannot stably abut against the inner side of the temperature measuring wall 15, the elastic force generated by the elastic element pushes the heating tube 1 to continue to swing towards the temperature measuring wall 15, ensuring that the heating tube 1 can be in contact with the temperature measuring wall 15. Since the heating tube 1 has detached from the support frame 17 at this time, in order to ensure that the heating tube 1 only swings towards the temperature measuring wall 15, an arc-shaped structure is provided at the position where the elastic element contacts the heating tube 1 to fit into the heating tube 1, ensuring that the swing direction of the heating tube 1 is fixed.
[0031] The heating channel 2 is also equipped with a water inlet 4 and a water outlet 6 at both ends. The water inlet 4 and the water outlet 6 are connected to the inner cavity of the heating channel 2. Cold water from the outside can enter the inner cavity of the heating channel 2 through the water inlet on the water inlet 4 for heating. The hot water heated by the heating channel 2 flows out of the heating channel 2 through the water outlet on the water outlet 6.
[0032] Furthermore, the water inlet 4 is also provided with a fixing hole, through which the heating tube 1 passes and is sealed and connected; the heating tube 1 extends into the heating channel 2, and the end of the heating tube 1 located outside the heating channel 2 is connected to the first wire 13 and the second wire 14 by welding; the heating tube 1 is connected to an external power source through the first wire 13 and the second wire 14.
[0033] The diameter of the end of the water inlet 4 and the water outlet 6 facing the heating channel 2 is smaller than the diameter of the heating channel 2. The end of the water inlet 4 and the water outlet 6 facing the heating channel 2 is the front end. The front end of the water inlet 4 and the water outlet 6 is inserted into the heating channel 2. A sealing element is set at the position where the water inlet 4 and the water outlet 6 coincide with the heating channel 2. The sealing element ensures the airtightness between the water inlet 4 and the water outlet 6 and the heating channel 2.
[0034] Preferably, the inlet sealing sleeve 3 and the outlet sealing sleeve 5 are respectively provided at the positions where the water inlet 4 and the water outlet 6 overlap with the heating channel 2;
[0035] To reduce the damage to the heating channel 2 caused by external forces during use, a protective sleeve 10 is also provided on the outside of the heating channel 2. Preferably, the protective sleeve 10 can be made of stainless steel, which can provide protection while also preventing excessive moisture from causing the protective sleeve 10 to rust and reduce its service life. The water inlet 4 and the water outlet 6 are fixedly connected to the protective sleeve 10 after being inserted into the heating channel 2.
[0036] Preferably, the side of the end of the water inlet 4 and the water outlet 6 exposed outside the heating channel 2 is provided with a fixing ear plate. The fixing ear plate fixes the water inlet 4 and the water outlet 6 to the side of the protective sleeve 10, thereby further improving the connection strength between the water inlet 4 and the water outlet 6 and the heating channel 2.
[0037] Through holes are opened on the protective sleeve 10 at positions corresponding to the temperature measuring wall 15. The number of through holes is the same as the number of reset temperature controllers. In this embodiment, the reset temperature controllers include an automatic reset temperature controller 11 and a manual reset temperature controller 12. The automatic reset temperature controller 11 and the manual reset temperature controller 12 are fixedly installed in the corresponding through holes. The temperature control probes at the ends of the automatic reset temperature controller 11 and the manual reset temperature controller 12 abut against the temperature measuring wall 15 to improve the sensitivity of temperature detection.
[0038] An installation hole communicating with the heating channel 2 is provided on the water outlet 6. The temperature sensor 7 is inserted into the installation hole and sealed to the installation hole. The temperature sensor 7 is fixed in the installation hole by the locking pin 9. After the instant heating device heats the cold water, it detects the temperature of the heated cold water through the temperature sensor 7. The heating efficiency of the heating tube 1 is adjusted according to the temperature measured by the temperature sensor 7, so as to obtain hot water at a suitable temperature.
[0039] Preferably, a sealing ring 8 is provided on the outer surface of the temperature sensor 7. The sealing ring 8 is deformed by the compression between the temperature sensor 7 and the mounting hole, thereby ensuring the sealing between the temperature sensor 7 and the mounting hole.
[0040] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
