The detailed features and advantages of the embodiments of the present invention are described in detail in the following description, and the contents are sufficient to enable any person with ordinary knowledge in the art to understand the technical content of the embodiments of the present invention and implement them accordingly, and according to the disclosure in this specification Any person with ordinary knowledge in the art can easily understand the related objects and advantages of the present invention. The following examples further illustrate the concept of the present invention in detail, but do not limit the scope of the present invention in any way.

Please refer to Figure 1 and Figure 2. FIG. 1 is a system configuration diagram of a water temperature control system according to an embodiment of the present invention. 2 is a perspective view of a water heater according to an embodiment of the present invention.

In one embodiment of the present invention, the water temperature control system may include a water heater 1 , a water outlet 2 , an external pipeline 3 and a water outlet element 4 .

The water heater 1 may include a casing 11 , an internal pipeline 12 , a heating device 13 , a controller 14 and a power adjustment element 15 .

The casing 11 has an accommodating space. Internal piping 12 is located in the containment empty and the internal pipeline 12 is used for conveying a working fluid (eg, water). The heating device 13 is located in the accommodating space, and the heating device 13 is used for heating the working fluid in the inner pipeline 12 . The heating device 13 may be, for example, a burner for a gas water heater or an electric heating rod for an electric water heater. In this embodiment, the heating device 13 is a burner of a gas water heater as an example of the heating device 13, but the present invention is not limited to this.

The controller 14 is electrically connected to the heating device 13 and is used for controlling the heating device 13 to operate with a preset power. The power adjustment element 15 is disposed on the casing 11 and is electrically connected to the controller 14, so that the controller 14 controls the heating device 13 to operate at an increased power greater than the preset power for a preset time, and after the preset time elapses , so that the controller 14 controls the heating device 13 to operate at a preset power. In other words, when the user finds that the water temperature of the hot water provided by the water heater 1 is lower than the expected water temperature, the user can manually trigger the power adjustment element 15 to make the water heater 1 operate at a higher power than the preset power within a preset time. The power of the water heater 1 can be used to operate, thereby increasing the water temperature of the hot water provided by the water heater 1 . In this way, even if the hot water provided by the water heater 1 is affected by the low temperature of the wall surface in contact with the external pipeline 3 or the low temperature of the outside air temperature, the water temperature of the hot water provided by the water heater 1 can be maintained as much as possible at the expected water temperature. Or provide hot water at the expected water temperature as soon as possible.

The water outlet 2 is located on the water heater 1 . One side of the external pipeline 3 is communicated with the water heater 1 via the water outlet 2 . The water outlet element 4 communicates with the side opposite to the side where the external pipeline 3 communicates with the water heater 1 . In this embodiment, the water outlet element 4 is, for example, a faucet or a shower head installed in a bathroom. The external pipeline 3 is, for example, a water pipe embedded in the wall of the bathroom or installed on the wall, and used to connect the water heater 1 and the water outlet element 4 . When the hot water flows through the external pipe 3 , the heat of the hot water will be transferred to the wall or the outside air, and the heat transferred to the wall or the outside air will be proportional to the length of the external pipe 3 . In addition, if the length of the external pipeline 3 is longer, it means that more heat is lost from the hot water in the external pipeline 3. Therefore, it is necessary to increase the difference between the increased power and the preset power to prevent the actual temperature of the hot water from being lower than expected temperature. That is to say, the difference between the increased power and the preset power is roughly positively correlated with the length of the external pipeline 3 , so the set value of the increased power of the water heater 1 can be set according to the length of the external pipeline 3 . When the external pipeline 3 is longer, the difference between the increased power and the preset power is larger.

In this embodiment, the water heater 1 may further include a power input interface 16 . The power input interface 16 is disposed on the casing 11 and is electrically connected to the controller 14, and is used for setting the preset power and increasing the power.

In this embodiment, the controller 14 can further be used to execute a power determination procedure. The power judging procedure includes judging whether the set increased power is greater than or equal to the maximum power of the heating device 13 . If so, the controller 14 makes the heating device 13 heat the working fluid in the inner pipeline 12 with the maximum power of the heating device 13 . If not, the controller 14 instructs the heating device 13 to heat the working fluid in the inner pipeline 12 with the set increased power. In other words, if the currently set parameters (eg, temperature, power) will cause the water heater 1 to be overloaded, the controller 14 will make the water heater 1 operate at the maximum load power. The purpose of controlling the water heater to operate at a power not exceeding the maximum load is to avoid carbon dioxide emissions caused by excessive use of the water heater 1, and to further comply with safety regulations.

In this embodiment, the water heater 1 may further include a time setting interface 17. The time setting interface 17 is disposed on the casing 11 and is electrically connected to the controller 14, wherein the time setting interface 17 is used for setting a preset time.

In this embodiment, the water heater 1 may further include a timing element 18 . The timing element 18 is disposed in the casing 11 and is electrically connected to the controller 14 , wherein the timing element 18 sends a timing signal to the controller 14 after a preset time. The signal enables the controller 14 to control the heating device 13 to operate at a preset power. In other words, within the preset time, the water heater 1 will operate with a power greater than the preset power, thereby increasing the water temperature of the hot water provided by the water heater 1 at the beginning. In this way, even if the hot water provided by the water heater 1 at the beginning is affected by the low temperature of the wall surface in contact with the external pipeline 3 or the low temperature of the outside air temperature, the water temperature of the hot water provided by the water heater 1 at the beginning can be maintained as much as possible. Provide hot water at the expected water temperature or as soon as possible. However, the temperature of the wall surface in contact with the external pipeline 3 will rise because the water heater 1 is continuously turned on, thereby reducing the heat exchange between the hot water provided by the water heater 1 and the wall surface in contact with the external pipeline 3, so the wall surface in contact with the external pipeline 3 is reduced. The influence of the low temperature on the temperature of the hot water provided by the water heater 1 will also decrease accordingly. Therefore, if the water heater 1 still operates with a larger power than the preset power after the preset time, the temperature of the hot water provided by the water heater 1 may be higher than the expected water temperature. In this embodiment, after the preset time has elapsed, the controller 14 will control the heating device to switch from increasing the power to running at the preset power corresponding to the expected temperature. In this way, it can be avoided that the temperature of the hot water provided by the water heater 1 after the preset time is higher than the expected temperature, causing inconvenience and discomfort to the user in toileting.

In addition, setting the preset time can avoid switching the water heater 1 from the increased power back to the preset power due to forgetting, and further avoid the excessive use of the water heater 1. Carbon monoxide emissions and energy waste.
