Abstract
Description
Technical Field
[0001] The invention relates to a temperature-controlled water outlet system and a method for controlling the outlet water temperature. Background Art
[0002] Traditionally, in order to obtain water of the right temperature from a faucet, users need to manually operate the faucet handle to adjust the supply ratio of cold water to hot water in a purely mechanical way to adjust the water temperature out of the faucet. However, with the above adjustment method, users must repeatedly confirm the water temperature to know whether the adjusted water temperature meets expectations.
[0003] To solve the above problems, the industry has developed a conventional electronic temperature-controlled water outlet system, whereby the user only needs to pre-set the water temperature in the system, and the system can automatically adjust the ratio of cold water to hot water, eliminating the need for the user to repeatedly confirm the water temperature. However, the system can only control the water temperature in the system before the water is discharged, and the water temperature that the user really needs is the water temperature when the water flows out into the container. For example, the user sets the water temperature in the system to 90 degrees Celsius, but when the water flows out into the container, the water temperature has become between 87-89 degrees Celsius, so the conventional system cannot accurately control the water temperature in the container.
[0004] In view of this, the development of a temperature-controlled water outlet system that can accurately control the water temperature in a container has long been anticipated by the industry. Summary of the invention
[0005] Therefore, to achieve the above-mentioned purpose, an embodiment of the present invention relates to a temperature-controlled water outlet system, which includes: a temperature control module, which is configured to output a first fluid having a first temperature and a second fluid having a second temperature, respectively; a faucet, which includes a temperature sensor, for detecting a third temperature of the surface of the third fluid when the third fluid is in a container, and the third fluid includes the first fluid alone or the second fluid or a mixture of the first fluid and the second fluid; a setting device, which is used for a user to set a preset temperature; and an operation processing device, which is configured to compare the difference between the third temperature and the preset temperature.
[0006] Another embodiment of the present invention relates to a method for controlling the outlet water temperature, comprising: dividing the fluid into a first fluid having a first temperature and a first flow rate and a second fluid having a second flow rate via a flow controller; heating the second fluid with a heater to have a second temperature, the second temperature being greater than or equal to the first temperature; draining the first fluid alone or the second fluid, or a mixture of the first fluid and the second fluid into a third fluid with a faucet; detecting a third temperature of the third fluid when the third fluid is in a container with a temperature sensor; and comparing the difference between the preset temperature and the third temperature.

[0014] In order to more clearly understand the features, contents and advantages of the present invention and the effects that can be achieved, the present invention is described in detail as follows in conjunction with the accompanying drawings and in the form of embodiments. The drawings used therein are only for illustration and auxiliary description purposes, so the proportions and arrangement relationships of the drawings should not be interpreted or limited to the claims of the present invention.
[0015] Please refer to Figure 1 . Figure 1 Schematic diagram of a temperature-controlled water outlet system 1 of a preferred embodiment of the present invention. The temperature-controlled water outlet system 1 includes a temperature control module 2, a faucet 3, a setting device 4, and an operation processing device 5. The temperature control module 2 includes a first inlet 21, a flow controller 22, a heater 25, a first outlet 26, a second outlet 27, and a steam exhaust port 28. The first inlet 21 is connected to the water inlet end to provide a fluid to flow into the temperature control module 2. The flow controller 22 is configured to divert the fluid flowing into the temperature control module 2 to the first path 23 to become a first fluid with a first flow rate and to divert the fluid to the second path 24 to become a second fluid with a second flow rate, wherein the first fluid has a first temperature, which is substantially the same as the temperature of the fluid when it flows into the first inlet 21, for example: the temperature of normal temperature water. The heater 25 is arranged in the second path 24 to heat the second fluid to a second temperature, so that the second temperature of the second fluid is greater than the first temperature of the first fluid. The steam generated when the heater 25 heats the second fluid is discharged from the temperature control module 2 through the steam exhaust port 28.
[0016] The first outlet 26 is located at the end of the first path 23 for outputting the first fluid. The second outlet 27 is located at the end of the second path 24 for outputting the second fluid. Figure 1 As shown, the first fluid and the second fluid flow out of the temperature control module 2 through the first outlet 26 and the second outlet 27 respectively. In other embodiments of the present invention (not shown), the first fluid and the second fluid may first merge into a third fluid inside the temperature control module 2 and then be output to the faucet 3.
[0017] The faucet 3 includes a second inlet 31, a third outlet 32, a temperature sensor 33 and a discharge port 34. The third outlet 32 is connected to the second inlet 31. Figure 1 As shown, the second inlet 31 of the faucet 3 is connected to the first outlet 26 and the second outlet 27 of the temperature control module 2 via a pipeline, so that the first fluid and the second fluid can be merged into a third fluid in the faucet 3. For example, the first fluid and the second fluid can be merged between the second inlet 31 and the third outlet 32 of the faucet 3 to form a third fluid. In another embodiment of the present invention, Figure 2 As shown, the first fluid and the second fluid do not converge into the third fluid in the faucet 3, that is, the first outlet 26 and the second outlet 27 of the temperature control module 2 pass through the second inlet 31 and the third outlet 32 of the faucet 3 via a pipeline, so that the first fluid and the second fluid are mixed in the container 6 to form the third fluid after flowing out of the faucet 3. In addition, the third fluid in the container 6 may only contain the first fluid or the second fluid according to the use requirements. When the user wants to use normal temperature water, the first fluid flows out of the faucet 3 at normal temperature. In this case, the third fluid only contains the first fluid; but when the user wants to use water with a temperature higher than that of normal temperature water, the user can control the temperature control module 2 through the setting device 4 to control the heater 25 to heat the second fluid, so that the second fluid is heated to an appropriate temperature and then flows out of the faucet 2. In this case, the third fluid may only contain the second fluid or a mixture of the first fluid and the second fluid. In another embodiment of the present invention, the first fluid and the second fluid have already converged into the third fluid before flowing into the faucet 3, for example, between flowing out from the temperature control module 2 to the faucet 3 (such as Figure 3 As shown), or first converged inside the temperature control module 2 and then output (not shown).
[0018] The temperature sensor 33 is used to detect the third temperature of the surface 61 of the third fluid when the third fluid is in the container 6. The temperature sensor 33 is disposed on the faucet 3 and on the same side as the third outlet 32, so that the temperature sensor 33 faces the surface 61 of the third fluid in the container 6. In a specific embodiment of the present invention, the temperature sensor 33 is an infrared (IR) temperature sensor.
[0019] The discharge port 34 of the faucet 3 is connected to the steam discharge port 28 of the temperature control module 2 via a pipeline, so that the steam generated when the second fluid is heated can be discharged into the environment through the steam discharge port 28 of the temperature control module 2 and the discharge port 34 of the faucet 3, so as to avoid the situation where the pressure of the water out of the faucet 3 caused by the steam during heating causes splashing. In the embodiment of the present invention, if Figure 1-3 As shown, the discharge port 34 is disposed on the upper side of the faucet 3. In other embodiments of the present invention, the discharge port 34 of the faucet 3 may be disposed on the rear side of the faucet 3 or other appropriate positions (not shown).
[0020] The setting device 4 is used for the user to set the preset water temperature. The setting device 4 includes a display screen and a temperature control key. The user sets the desired preset temperature via the temperature control key, and the preset temperature value is displayed in real time via the display screen. In an embodiment of the present invention, the temperature control key is arranged below the display screen and on the upper surface of the faucet 3, so that when the user operates the temperature control key, the hand will not cover the display screen, and the user is convenient to operate. In an embodiment of the present invention, the setting device 4 has a waterproof surface, and a waterproof structure is arranged at the installation position of the faucet 3 to prevent water from penetrating.
[0021] The processing device 5 is configured to compare the difference between the third temperature of the surface 61 of the third fluid in the container 6 and the preset temperature of the setting device 4, and to perform the water temperature control mechanism based on the difference. Figure 1-3 As shown, the operation processing device 5 is disposed in the faucet 3. In other embodiments of the present invention, the operation processing device 5 may also be disposed in the temperature control module 2 (not shown) or other locations.
[0022] A first preferred embodiment of the method for controlling the outlet water temperature of the present invention is as follows: Figure 4 The method for controlling the outlet water temperature includes the following steps:
[0023] (a) dividing the fluid into a first fluid having a first temperature and a first flow rate and a second fluid having a second flow rate via a flow controller 22;
[0024] (b) heating the second fluid by the heater 25 to have a second temperature;
[0025] (c) using the faucet 3 to drain the first fluid alone or the second fluid, or a mixture of the first fluid and the second fluid into a third fluid;
[0026] (d) using the temperature sensor 33 to detect a third temperature of the surface of the third fluid when the third fluid is in the container 6;
[0027] (e) the processing device 5 compares the difference between the preset temperature and the third temperature;
[0028] (f) Based on the temperature difference obtained in step (e), the operation processing device 5 instructs the flow controller 22 to adjust the ratio of the first flow rate to the second flow rate, thereby adjusting the third temperature of the third fluid. In step (f), when the third temperature of the third fluid is lower than the preset temperature, the operation processing device 5 instructs the flow controller 22 to reduce the second flow rate (so that the temperature of the second fluid can be increased more quickly) or to simultaneously reduce the second flow rate and reduce the first flow rate, thereby increasing the third temperature of the third fluid. Conversely, when the third temperature of the third fluid is higher than the preset temperature, the operation processing device 5 instructs the flow controller 22 to increase the second flow rate (to reduce the temperature rise rate of the second fluid by increasing the flow rate) or to simultaneously increase the first flow rate and increase the second flow rate, thereby reducing the third temperature of the third fluid.
[0029] A second preferred embodiment of the method for controlling the outlet water temperature of the present invention is as follows: Figure 5 As shown. Steps (a') to (e') of the second preferred embodiment are substantially the same as steps (a) to (e) of the previous first preferred embodiment, but step (f') is different from step (e) of the previous first preferred embodiment. In step (f'), based on the temperature difference obtained in step (e'), the operation processing device 5 instructs the flow controller 22 to adjust the second temperature of the second fluid, thereby adjusting the third temperature of the third fluid. When the temperature sensor 33 detects that the third temperature is lower than the preset temperature, the operation processing device 5 instructs the heater 25 to increase the heating power of the second fluid to increase the second temperature of the second fluid, thereby increasing the third temperature of the third fluid. Conversely, when the temperature sensor 33 detects that the third temperature is higher than the preset temperature, the operation processing device 5 instructs the heater 25 to reduce the heating power of the second fluid to reduce the second temperature of the second fluid (the second temperature is higher than or equal to the first temperature), so that the second temperature is lower than the third temperature, thereby reducing the third temperature of the third fluid.
[0030] A third preferred embodiment of the method for controlling the outlet water temperature of the present invention is as follows: Figure 6As shown. Steps (a") to (e") of the third preferred embodiment are substantially the same as steps (a) to (e) of the first preferred embodiment, but step (f") is different from step (f) of the first preferred embodiment. In step (f"), based on the difference in step (e"), the processing device 5 instructs the flow controller 22 to adjust the ratio of the first flow rate to the second flow rate, and the processing device 5 also instructs the heater 25 to adjust the second temperature of the second fluid, thereby adjusting the third temperature of the third fluid. When the temperature sensor 33 detects that the third temperature is lower than the preset temperature, the processing device 5 instructs the flow controller 22 to reduce the second flow rate or to perform the operation simultaneously. The processing device 5 instructs the flow controller 22 to increase the second flow rate or increase the first flow rate and increase the second flow rate at the same time, and the processing device 5 instructs the heater 25 to reduce the heating power of the second fluid to increase the second temperature of the second fluid, thereby increasing the third temperature of the third fluid. Conversely, when the temperature sensor 33 detects that the third temperature is higher than the preset temperature, the processing device 5 instructs the flow controller 22 to increase the second flow rate or increase the first flow rate and increase the second flow rate at the same time, and the processing device 5 instructs the heater 25 to reduce the heating power of the second fluid to reduce the second temperature of the second fluid (the second temperature is higher than or equal to the first temperature), thereby reducing the third temperature of the third fluid.
