Abstract
Description
Technical Field
[0001] This application relates to the field of water purifier equipment technology, and in particular to a circulating water circuit structure and a water purifier. Background Technology
[0002] A water purifier is a household appliance that integrates filtration and heating functions, primarily used to provide safe and healthy drinking water. It removes impurities, bacteria, and harmful substances from water through multiple filtration technologies, and also has a heating function to directly provide hot water for daily drinking, tea brewing, coffee making, and other needs.
[0003] Traditional water purifiers mostly use a hot water tank, with a heating plate at the bottom. Cold water enters the tank, is first boiled by the heating plate, and then stored as hot water. When water is needed, the water is drawn out of the tank. Currently, most water purifiers on the market use an integrated design for the hot water tank and heating plate. This makes it easy for heat to be lost from the heating plate, leading to a drop in water temperature in the tank and insufficient hot water output. Adding multiple heating modules would increase costs or lead to excessive power consumption. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of this application and are not intended to limit the embodiments of this application.
[0032] This application provides a circulating waterway structure. Figure 1 This is a schematic diagram of a circulating water system structure provided in an embodiment of this application, such as... Figure 1 As shown, the circulating water circuit structure includes an inlet pipe 1, a heat storage module 3, a heating module 2, a circulation pipe 4, a circulation valve 5, and an outlet pipe 6.
[0033] like Figure 1 As shown, the inlet of the heat storage module 3 is connected to the outlet of the inlet pipe 1, the outlet of the heat storage module 3 is connected to the inlet of the heating module 2, and the outlet of the heating module 2 is connected to the inlet of the outlet pipe 6. The inlet of the circulation pipe 4 is connected to the outlet of the heating module 2, and the outlet of the circulation pipe 4 is connected to the inlet of the heat storage module 3. A circulation valve 5 is installed at the inlet of the circulation pipe 4 to draw the heat storage medium heated by the heating module 2 into the circulation pipe 4 and then into the heat storage module 3.
[0034] When the heat storage medium, such as water, enters the inlet pipe 1 and then the heat storage module 3, it is further heated by the heating module 2 and then flows out through the outlet pipe 6 for immediate use by the user. When not in use, the circulating water system can still store hot water. The hot water heated by the heating module 2 enters the circulation pipe 4 through the circulation valve 5 and then enters the heat storage module 3 for storage. If the hot water is stored in the heat storage module 3 for a long time, its temperature may drop. The water flowing out of the heat storage module 3 can be reheated by the heating module 2 and then flows out through the outlet pipe 6 for user use. Through the above settings, the circulation pipe 4 and the circulation valve 5 circulate the heat storage medium in the circulating water system, allowing it to be reheated by the heating module 2 before being discharged, ensuring that the outlet water temperature meets the requirements.
[0035] The heat storage module 3 includes a vacuum heat storage tank 31, the interior of which is in a vacuum state. By using a vacuum heat storage tank 31, the heat exchange between the heat storage medium and the air inside the vacuum heat storage tank 31 is reduced, thus optimizing the heat storage effect of the heat storage module 3. At the same time, the separate arrangement of the heating module 2 and the heat storage module 3 reduces heat loss at the heating module 2, further ensuring the outlet water temperature.
[0036] Figure 2 This is a schematic diagram of a circulating water system structure provided in an embodiment of this application, such as... Figure 2 As shown, in some possible embodiments, the circulating water circuit structure also includes a first temperature detection element 7 and a control module.
[0037] In some possible embodiments, the first temperature detection element 7 is disposed between the water outlet of the vacuum heat storage tank 31 and the water inlet of the heating module 2, and is used to detect the first temperature data of the heat storage medium in the vacuum heat storage tank 31. Specifically, the first temperature detection element 7 is configured as a temperature sensor, which can detect the temperature of the water flowing through the water outlet of the vacuum heat storage tank 31 in real time.
[0038] In this embodiment, the first temperature sensor 7 is communicatively connected to the control module and is used to send first temperature data to the control module. The control module is communicatively connected to the heating module 2 and is used to control the heating module 2 based on the first temperature data.
[0039] If the first temperature sensor 7 detects that the water temperature in the vacuum storage tank 31 is 3 degrees Celsius below the boiling point, for example, 97 degrees Celsius, it is considered that the water does not need to be reheated and the heating module 2 does not need to be activated. If the first temperature sensor 7 detects that the water temperature in the vacuum storage tank 31 is below 97 degrees Celsius, the heating module 2 can be activated to reheat the water, and then the water will flow out through the water outlet pipe 6 to ensure that the water temperature meets the requirements.
[0040] In some possible embodiments, the circulating water circuit structure also includes a second temperature sensing element 8. For example... Figure 2 As shown, the second temperature detection element 8 is set between the water outlet of the heating module 2 and the water inlet of the circulation pipe 4, and is used to detect the second temperature data of the heat storage medium after it is heated by the heating module 2.
[0041] In this embodiment, the second temperature sensor 8 is communicatively connected to the control module and is used to send second temperature data to the control module. The control module is communicatively connected to the circulation valve 5 and is used to control the circulation valve 5 based on the second temperature data.
[0042] In one possible embodiment, the temperature after being heated by the heating module 2 can be detected in real time using the second temperature data. If the water temperature after being heated by the heating module 2 (including one instantaneous heating and multiple cyclic heating) is lower than 97 degrees Celsius, the circulation valve 5 can be opened to allow the water to enter the circulation pipe 4 and be heated again through the vacuum heat storage tank 31 and the heating module 2. If the water temperature after being heated by the heating module 2 is higher than or equal to 97 degrees Celsius, the circulation valve 5 can be closed to allow the water to enter the outlet pipe 6 for user use.
[0043] In other possible implementations, the power of the heating module 2 can be controlled based on the temperature difference between the first temperature data and the second temperature data, thereby saving energy while ensuring the outlet water temperature.
[0044] For example, if the first temperature data indicates that the water temperature is 95 degrees Celsius, and the water temperature needs to be heated to 97 degrees Celsius, then the second temperature data needs to be 97 degrees Celsius. In this case, the power of the heating module 2 can be adjusted to the first power.
[0045] The first temperature data indicates a water temperature of 65 degrees Celsius, but the water temperature needs to be heated to 97 degrees Celsius, which means the second temperature data needs to be 97 degrees Celsius. At this time, the power of the heating module 2 can be adjusted to the second power, which is greater than the first power.
[0046] In some possible embodiments, the circulating water circuit structure also includes a water pump 9. The water pump 9 is located between the water outlet of the vacuum heat storage tank 31 and the water inlet of the heating module 2, and is used to extract the heat storage medium in the vacuum heat storage tank 31 and send it into the heating module 2 and subsequent pipelines.
[0047] In this embodiment, the water pump 9 is configured as a bidirectional water pump 9. The bidirectional water pump 9 can send the heat storage medium in the vacuum heat storage tank 31 into the heating module 2 and the water outlet pipe 6, and can also pump the heat storage medium in the heating module 2 and the water outlet pipe 6 back into the vacuum heat storage tank 31.
[0048] In some possible embodiments, the circulating water circuit structure also includes an outlet valve 61, which is specifically configured as a solenoid valve and is installed on the outlet pipe 6 to transport the heat storage medium in the outlet pipe 6 to the outlet.
[0049] In some possible embodiments, the circulating water circuit structure also includes a one-way valve 11 and an inlet valve 12.
[0050] like Figure 2 As shown, both the one-way valve 11 and the inlet valve 12 are installed on the inlet pipe 1, with the one-way valve 11 located near the inlet end of the inlet pipe 1 and the inlet valve 12 located near the outlet end of the inlet pipe 1. The inlet valve 12 is also configured as a solenoid valve, used to transport the heat storage medium from the inlet to the inlet pipe 1, and the one-way valve 11 is used to ensure that the water in the inlet pipe 1 flows in one direction to prevent backflow.
[0051] In some possible embodiments, the thermal storage module 3 further includes a high water level probe 32. The high water level probe 32 is disposed at the top of the vacuum thermal storage tank 31 and is used to detect the water level of the thermal storage medium in the vacuum thermal storage tank 31. The high water level probe 32 is communicatively connected to the control module and sends the water level status to the control module. Based on the water level status, the control module controls the water inlet valve 12 to stop water intake when the vacuum thermal storage tank 31 is full.
[0052] In some possible embodiments, the thermal storage module 3 also includes a vacuum exhaust valve 33. The vacuum exhaust valve 33 is located at the top of the vacuum thermal storage tank 31 and is used to balance the air pressure in the vacuum thermal storage tank 31. The vacuum exhaust valve 33 can be opened when water enters and exits the vacuum thermal storage tank 31, making the water entry and exit smoother.
[0053] This application embodiment also provides a water purifier, which includes the above-mentioned circulating water circuit structure and a water purification pipeline structure, wherein the water purification pipeline structure is used to purify the incoming water, and the circulating water circuit structure is used to heat the purified water.
[0054] By incorporating a reflux water circuit structure within the water purifier and employing a vacuum heat storage tank, heat exchange between the heat storage medium and the air is reduced. Separating the heating module and the heat storage device minimizes heat loss at the heating module. Furthermore, using a single heating module in conjunction with a circulation valve and circulation pipeline avoids the problems of excessive power consumption and increased costs associated with operating multiple heating modules simultaneously. Positioning the heating module after the heat storage tank, along with the circulation solenoid valve and pipeline, circulates and heats the water, ensuring the outlet water temperature meets requirements. Additionally, placing the heating module after the vacuum heat storage tank allows for timely activation, further guaranteeing sufficiently hot water.
[0055] It should be noted that the order of the embodiments described above is merely for descriptive purposes and does not represent the superiority or inferiority of the embodiments. Furthermore, specific embodiments have been described above. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps described in the claims can be performed in a different order than that shown in the embodiments and still achieve the desired result. Additionally, the processes depicted in the drawings do not necessarily require a specific or sequential order to achieve the desired result.

[0056] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to mutually.
