AI Technical Summary
Existing water tank heaters are prone to bursting due to the expansion of the internal liquid freezing in low-temperature environments, lacking antifreeze function.
A reflux baffle is installed inside the water tank heater to separate it into a heating space and an antifreeze space, which are connected by a reflux guide hole. The heated water mixes with the water in the antifreeze space, and an air margin is maintained to resist ice expansion. Combined with a double-layer thermostat and leakage protection device, safety is ensured.
It effectively prevents the water tank from freezing and expanding at temperatures as low as -35 degrees Celsius, protecting the tank from damage, while also ensuring the safe use of the heater in low-temperature environments and preventing dry burning.

[0026] Embodiments
[0027] As Figures 1-3As shown, the embodiment provides a water tank heater with anti-freezing space 102, comprising a tank body 1, the inside of the tank body 1 is integrally formed with a backflow partition layer 2, the backflow partition layer 2 separates the tank body 1 into two spaces, a heating space 101 at the bottom and an anti-freezing space 102 at the top, the backflow partition layer 2 is provided with a backflow guide hole 21, the side of the tank body 1 is provided with a water inlet 3 and a water outlet 4, the water inlet 3 is in through connection with the heating space 101, the water outlet 4 is in through connection with the anti-freezing space 102, and the heating space 101 is provided with a heating pipe 5. Tap water enters the heating space 101 through the water inlet 3, is heated by the heating pipe 5, enters the anti-freezing space 102 from the backflow guide hole 21, and is stirred and mixed with the water in the anti-freezing space 102, so that the water of different temperatures reaches a relatively balanced state after stirring and mixing, and then is discharged from the water outlet 4 for use by the user. The air allowance of the anti-freezing space 102 and the water storage ratio reach 14.96% (the ratio of the space above the water outlet 4 to the water storage capacity of the heating space 101 below the water outlet 4), in a low-temperature environment, the water remaining in the tank body 1 freezes and expands, and the air allowance remaining in the anti-freezing space 102 can meet the increased volume of the frozen and expanded water, preventing the tank body 1 from being broken by expansion.
[0028] Further, the vertical distance between the water inlet 3 and the bottom of the heating space 101 is 7 mm. A 7 mm water storage layer is left at the bottom of the heating space 101 to prevent tap water from being sucked back in the case of water stop, causing the heater to run out of water and dry out, and to prevent the heating pipe 5 from heating the water in the tank body 1 at the moment of starting the heater, causing the water vapor to rapidly trigger the temperature controller to disconnect and thus to protect the heater from power failure.
[0029] In an embodiment, the surface of the tank body 1 is provided with a first mounting hole 6, and a first temperature controller 61 is embedded in the first mounting hole 6. The first temperature controller 61 is used to detect the water temperature in the heating space 101, and if the water temperature in the heating space 101 is too high, the first temperature controller 61 will disconnect the power supply, thereby protecting the heater.
[0030] Further, the distance between the detection end of the first temperature controller 61 and the heating pipe 5 is 3 mm. The first temperature controller 61 is installed 3 mm above the heating pipe 5, so that when the temperature is too high, the first temperature controller 61 can disconnect the power supply at the fastest speed, thereby protecting the heater.
[0031] In an embodiment, the surface of the tank body 1 is provided with a second mounting hole 7, and a second temperature controller 71 is embedded in the second mounting hole 7, and the detection end of the second temperature controller 71 is arranged close to the water outlet 4. The second temperature controller 71 is used to detect the water temperature in the anti-freezing space 102, and if the temperature is too high, the second temperature controller 71 will disconnect the power supply, thereby protecting the heater.
[0032] In an embodiment, a third mounting hole 8 is arranged on the surface of the box 1 close to the backflow guide hole 21, and a temperature detector 81 is embedded in the third mounting hole 8. The temperature detector 81 detects the temperature of the water flowing into the upper layer and sends the detected data to the control system to assist in adjusting the temperature to a suitable range.
[0033] In an embodiment, two parallel mounting blocks 9 are fixedly connected to the side surface of the box 1, and long strip-shaped mounting holes 91 are arranged on the mounting blocks 9. The long strip-shaped mounting holes 91 can be used to adjust the installation position at will, thereby solving the problem of inconsistent installation holes.
[0034] In an embodiment, the water outlet 4 is arranged at the bottom of the anti-freezing space 102. By arranging the water outlet 4 at the bottom of the anti-freezing space 102, the space above the water outlet 4 accounts for 14.96% of the space below the water outlet 4, and sufficient space is reserved to prevent the stored water from freezing and expanding to burst the box 1.
[0035] In an embodiment, a leakage protection device 10 is connected between the first temperature controller 61 and the second temperature controller 71. The leakage protection device 10 prevents leakage and improves safety.
[0036] The working principle of the utility model is as follows: tap water enters the heating space 101 through the water inlet 3, is heated by the heating pipe 5, enters the anti-freezing space 102 through the backflow guide hole 21, is stirred and mixed with the water in the anti-freezing space 102, and is promoted to reach a relatively balanced state after stirring and mixing of water of different temperatures, and then is discharged from the water outlet 4 for use by a user. The air allowance of the anti-freezing space 102 and the ratio of the stored water are 14.96% (the ratio of the space above the water outlet 4 to the storage capacity of the heating space 101 below the water outlet 4), in a low-temperature environment, the water in the box 1 freezes and expands, the air allowance of the anti-freezing space 102 can meet the increased volume of the frozen and expanded water, and the box 1 is prevented from being burst. The first temperature controller 61 and the second temperature controller 71 are arranged to ensure that the temperature is too high and the power is turned off in time, the water inlet 3 is moved upward to leave a 7mm water layer at the bottom of the heating space 101, the tap water is prevented from being sucked back to cause the heater to dry out in the water stop condition, the heating pipe 5 heats the stored water in the box 1 at the starting moment of the heater to rapidly promote the temperature controller to be disconnected and thus be protected by power-off.
[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, and are not intended to limit the present disclosure; although the present disclosure has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions recorded in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and these modifications or replacements do not make the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present disclosure.
