[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0026] Currently, the main function of water purifiers on the market is to filter and purify water, providing safe drinking water. However, as consumers' demands for quality of life increase, they are also placing more demands on the functions of water purifiers. For example, users may need water at different temperatures at different times of the day, such as hot water for making tea in the morning, ice water for quenching thirst at noon, and warm water for preparing formula in the evening. Regarding water temperature regulation, many water purifiers on the market still only provide room temperature water, requiring users to use other devices (such as kettles or refrigerators) to adjust the water temperature, or to directly replace the model of the water purifier. This not only increases operating costs but also reduces ease of use and leads to low energy efficiency.

[0027] Therefore, there is a need for a water purification auxiliary device that can expand or adjust the functions of a water purifier based on the original water purifier, increasing ease of use and reducing the burden on users. This application provides a water purification auxiliary device, such as... Figure 1 As shown, the water purification auxiliary device includes a normal temperature pipeline 1, a cold water pipeline 2, a hot water pipeline 3, a cooler 4, and a heating element 5. The cooler 4 is installed in the cold water pipeline 2, and the heating element 5 is installed in the hot water pipeline 3. The inlet of the normal temperature pipeline 1, the inlet of the cold water pipeline 2, and the inlet of the hot water pipeline 3 are all connected to the water purifier. The outlet of the normal temperature pipeline 1, the outlet of the cold water pipeline 2, and the outlet of the hot water pipeline 3 are all used to connect to the faucet.

[0028] Among them, the water purifier filters and purifies the connected tap water, removing impurities and improving its purity. The purified water it outputs can be called clean water. A water purification auxiliary device is connected to the purified water supply and further processes it before it is output from the connected faucet, thus meeting different user water needs.

[0029] Specifically, the inlets of the ambient temperature pipe 1, the cold water pipe 2, and the hot water pipe 3 are all connected to the water purifier. This means that the ambient temperature pipe 1, cold water pipe 2, and hot water pipe 3 are connected in parallel to the outlet of the water purifier, allowing for the intake of purified water. Different devices on each pipe achieve different water purification processes. The hot water pipe 3 is equipped with a heating element 5 to heat the flowing purified water, resulting in hot water output. The cold water pipe 2 is equipped with a cooler 4 to cool the flowing purified water, resulting in cold water output. The ambient temperature pipe 1 does not treat the purified water output from the water purifier; it directly outputs ambient temperature water. Clearly, the hot water output from the hot water pipe 3 is at a higher temperature than the ambient temperature water, while the cold water output from the cold water pipe 2 is at a lower temperature than the ambient temperature water. Since the outlets of the three pipes—normal temperature pipe 1, cold water pipe 2, and hot water pipe 3—can all be connected to faucets, purified water at different temperatures can be output through the faucets to meet the different water needs of users.

[0030] For example, the refrigerator 4 can be classified into compression refrigeration equipment, absorption refrigeration equipment, and thermoelectric refrigeration equipment according to its different working principles. Compression refrigeration equipment uses the compression and expansion of the refrigerant to absorb and release heat, thereby achieving a cooling effect; absorption refrigeration equipment uses the interaction between the absorbent and the refrigerant to generate cold air; and thermoelectric refrigeration equipment uses the thermoelectric effect to generate cold air. In this embodiment, the selection of the refrigerator 4 is not limited; the refrigerator 4 can be a semiconductor refrigerator 4, a heat exchange refrigerator 4, or a nuclear refrigerator 4, etc.

[0031] Optionally, such as Figure 1 As shown, the three pipes—room temperature pipe 1, cold water pipe 2, and hot water pipe 3—can be connected to the same faucet. The faucet can then connect to the corresponding pipe according to the user's selected flow method, achieving the output of purified water at different temperatures. Alternatively, the room temperature pipe 1, cold water pipe 2, and hot water pipe 3 can be connected to different faucets, i.e., three faucets are installed, each connected to one of the three pipes. In this case, the user can select to control the flow of different faucets, thereby controlling the flow of different pipes and outputting purified water at the temperature corresponding to that pipe.

[0032] Furthermore, the on / off control between the faucet and the pipeline can be achieved through user interaction with devices such as a touch screen or touch buttons, depending on the type, model, and setting of the faucet. In this embodiment, the user can choose the faucet as the water switch according to their needs. The operating status of the cooler 4 and the heating element 5 can also be controlled by the user. Cooling and heating can only be achieved when the user starts the cooler 4 and the heating element 5.

[0033] In this embodiment, the water purification auxiliary device includes a normal temperature pipeline 1, a cold water pipeline 2, a hot water pipeline 3, a cooler 4, and a heating element 5. The cooler 4 is installed in the cold water pipeline 2, and the heating element 5 is installed in the hot water pipeline 3. The inlets of the normal temperature pipeline 1, the cold water pipeline 2, and the hot water pipeline 3 are connected to the water purifier. The outlets of the normal temperature pipeline 1, the cold water pipeline 2, and the hot water pipeline 3 are connected to the faucet. By setting up the normal temperature pipeline 1, which can output normal temperature water, the hot water pipeline 3, which can output hot water, and the cold water pipeline 2, the water purifier can provide water at different temperatures to the faucet, in addition to purifying tap water. This compensates for the functional deficiencies of the water purifier, helps meet the different water needs of users, and improves the convenience of use.

[0034] In one embodiment, such as Figure 2 As shown, the water purification auxiliary device also includes a cold water reversing valve 6 and a cold water return pipe 7. The first end of the cold water return pipe 7 is connected to the outlet of the chiller 4 and the cold water pipe 2, and the second end of the cold water return pipe 7 is connected to the inlet of the chiller 4 and the cold water pipe 2. The cold water reversing valve 6 is located between the outlet of the cold water pipe 2, the chiller 4, and the first end of the cold water return pipe 7.

[0035] Specifically, the first end of the cold water return pipe 7 is located on the outlet side of the chiller 4 and is connected to the outlet of the cold water pipe 2, allowing purified water cooled by the chiller 4 to enter the cold water return pipe 7. The second end of the cold water return pipe 7 is located on the inlet side of the chiller 4 and is connected to the inlet of the cold water pipe 2, allowing the cooled purified water in the cold water return pipe 7 to be reintroduced into the cold water pipe 2, where it is cooled again by the chiller 4 to lower its temperature. In this way, the cold water return pipe 7 can be repeatedly cooled to achieve a lower temperature purified water output.

[0036] At the junction of the first end of the aforementioned cold water return pipe 7, the outlet of the chiller 4, and the outlet of the cold water pipe 2, a cold water reversing valve 6 is installed. This cold water reversing valve 6 can be a three-way valve, capable of controlling whether the clean water output from the outlet of the chiller 4 flows to the cold water return pipe 7 or to the outlet of the cold water pipe 2. When the cold water reversing valve 6 connects the first end of the cold water return pipe 7 and the outlet of the chiller 4, the clean water cooled by the chiller 4 flows into the cold water return pipe 7 for further cooling. When the cold water reversing valve 6 connects the outlet of the chiller 4 and the outlet of the cold water pipe 2, the clean water cooled by the chiller 4 flows to the outlet of the cold water pipe 2, reaching the faucet for user use.

[0037] Optionally, the cold water reversing valve 6 can be user-controlled to switch its direction of flow, thereby controlling the duration of the cooling return flow of purified water, that is, controlling the duration of the purified water circulation between the cold water return pipe 7 and the chiller 4, and thus controlling the temperature of the cold water. Then, the user controls the cold water reversing valve 6 to switch the flow to the outlet of the cold water pipe 2, outputting the cold water required by the user. The cold water reversing valve 6 can also have an internally set time-switching logic, for example, it can be set to open the cold water return pipe and the chiller 4 for a period of time during startup, and then switch to open the outlet of the chiller 4 and the cold water pipe 2 after a set time, outputting cold water.

[0038] Based on the same technical concept, similar structural improvements can be made to the hot water output. In one embodiment, such as... Figure 3 As shown, the water purification auxiliary device also includes a hot water reversing valve 8 and a hot water return pipe 9. The first end of the hot water return pipe 9 is connected to the outlet of the heating element 5 and the hot water pipe 3, and the second end of the hot water return pipe 9 is connected to the inlet of the heating element 5 and the hot water pipe 3. The hot water reversing valve 8 is located between the outlet of the hot water pipe 3, the heating element 5 and the first end of the hot water return pipe 9.

[0039] Specifically, the first end of the hot water return pipe 9 is located on the outlet side of the heating element 5 and connected to the outlet of the hot water pipe 3, allowing purified water heated by the heating element 5 to enter the hot water return pipe 9. The second end of the hot water return pipe 9 is located on the inlet side of the heating element 5 and connected to the inlet of the hot water pipe 3, allowing the heated purified water in the hot water return pipe 9 to be reintroduced into the hot water pipe 3, where it is reheated by the heating element 5 to further increase its temperature. In this way, the design of the hot water return pipe 9 allows for repeated heating of the purified water, achieving a higher temperature output.

[0040] At the intersection of the first end of the hot water return pipe 9, the outlet of the heating element 5, and the outlet of the hot water pipe 3, a hot water reversing valve 8 is installed. This hot water reversing valve 8 can be a three-way valve, which can control the flow of purified water from the outlet of the heating element 5 to the hot water return pipe 9 or to the outlet of the hot water pipe 3. When the hot water reversing valve 8 connects the first end of the hot water return pipe 9 and the outlet of the heating element 5, the purified water heated by the heating element 5 flows into the hot water return pipe 9 for reheating. When the hot water reversing valve 8 connects the outlet of the heating element 5 and the outlet of the hot water pipe 3, the purified water heated by the heating element 5 flows to the outlet of the hot water pipe 3, reaching the faucet for the user to use.

[0041] Optionally, the hot water reversing valve 8 can be controlled by the user to switch its conduction direction, thereby controlling the duration of the purified water heating and return flow, that is, controlling the duration of the purified water circulation between the hot water return pipe 9 and the heating element 5, and thus controlling the temperature of the hot water. Then, the user controls the hot water reversing valve 8 to switch the flow to the outlet of the hot water pipe 3, outputting the hot water required by the user. The hot water reversing valve 8 can also have an internally set time-switching logic, for example, it may conduct the hot water circuit pipe and the heating element 5 for a period of time during startup, and then switch to conducting the flow to the outlet of the heating element 5 and the hot water pipe 3 after a set time, outputting hot water.

[0042] Furthermore, the water purification auxiliary device can be equipped with a separate cold water reversing valve 6 and a cold water return pipe 7 to extend the temperature of the cold water, or it can be equipped with a separate hot water reversing valve 8 and a hot water return pipe 9 to extend the temperature of the hot water, or it can be as follows: Figure 3 As shown, it is equipped with a cold water reversing valve 6, a cold water return pipe 7, a hot water reversing valve 8, and a hot water return pipe 9, which can simultaneously expand the output temperature of cold water and hot water.

[0043] In the above embodiments, by setting up a return pipeline and a corresponding reversing valve, the purified water temperature can be repeatedly heated or cooled. The return pipeline realizes the circulation of the purified water heating or cooling process, and hot or cold water is output under the control of the reversing valve, which expands the temperature range of the output purified water and helps to improve the applicability of the water purification auxiliary device.

[0044] In one embodiment, the water purification auxiliary device further includes an inlet solenoid valve, through which the inlet of the ambient temperature pipeline 1, the inlet of the cold water pipeline 2, and the inlet of the hot water pipeline 3 are connected to the water purifier.

[0045] Specifically, inlet solenoid valves can be installed at the inlet of the ambient temperature pipeline 1, the inlet of the cold water pipeline 2, and the inlet of the hot water pipeline 3. These valves can control the on / off state of the water purifier and the water purification auxiliary device. Only when the outlet of the water purifier is connected to the three inlets of the water purification auxiliary device can purified water at different temperatures be output.

[0046] Optionally, the inlet solenoid valve can be located at the outlet of the water purifier, meaning there is only one inlet solenoid valve located at the outlet of the water purifier. In one embodiment, there are multiple inlet solenoid valves, respectively located at the inlet of the ambient temperature pipe 1, the inlet of the cold water pipe 2, and the inlet of the hot water pipe 3. Alternatively, there can be three inlet solenoid valves located at the inlet of the ambient temperature pipe 1, the inlet of the cold water pipe 2, and the inlet of the hot water pipe 3.

[0047] When the inlet configurations of the three inlets—normal temperature pipe 1, cold water pipe 2, and hot water pipe 3—are different, the number and location of the inlet solenoid valves can also differ. For example, such as... Figure 4 As shown, the inlet of cold water pipe 2 and the inlet of hot water pipe 3 separate after a section of common pipe, while the inlet of ambient temperature pipe 1 is connected to the outlet of the water purifier. In this case, an ambient temperature solenoid valve 10a can be installed at the inlet of ambient temperature pipe 1, and a temperature regulating solenoid valve 10b can be installed on the common pipe of cold water pipe 2 and hot water pipe 3.

[0048] In this embodiment, by setting an inlet solenoid valve to control the conduction state between the water purifier and each pipeline, the operation of the water purification auxiliary device can be controlled more accurately, improving the ease of use.

[0049] In one embodiment, such as Figure 4 As shown, the water purification auxiliary device also includes a first temperature sensor 11a, a second temperature sensor 11b, and a controller. The first temperature sensor 11a is located at the outlet of the cold water pipe 2, and the second temperature sensor 11b is located at the outlet of the hot water pipe 3. The first temperature sensor 11a, the second temperature sensor 11b, the cooler 4, and the heating element 5 are all connected to the controller.

[0050] Specifically, the first temperature sensor 11a is installed at the outlet of the cold water pipe 2 to collect the temperature of the cold water at the outlet of the cold water pipe 2; the second temperature sensor 11b is installed at the outlet of the hot water pipe 3 to collect the temperature of the hot water at the outlet of the hot water pipe 3. Both the first temperature sensor 11a and the second temperature sensor 11b are connected to the controller, which can transmit the collected cold water temperature and hot water temperature to the controller. The controller is also connected to the cooler 4 and the heating element 5. The user can input a set temperature into the controller, and the controller will control the working power of the cooler 4 or the heating element 5 to match the output cold water or hot water with the set temperature.

[0051] For example, when cooling purified water, if the temperature collected by the first temperature sensor 11a is lower than the set temperature, the controller can adjust the power of the cooler 4 to decrease so as to improve the temperature of the output cold water to match the set temperature; when heating purified water, if the temperature collected by the second temperature sensor 11b is lower than the set temperature, the controller can adjust the power of the heating element 5 to increase so as to improve the temperature of the output hot water to match the set temperature.

[0052] Furthermore, in one embodiment, such as Figure 4 As shown, the water purification auxiliary device also includes a third temperature sensor 11c, which is installed at the inlet of the ambient temperature pipeline 1, the inlet of the cold water pipeline 2, and the inlet of the hot water pipeline 3, and is connected to the controller.

[0053] Specifically, the third temperature sensor 11c can be installed at the water purifier's outlet, which is equivalent to installing it at the inlet of the ambient temperature pipe 1, the inlet of the cold water pipe 2, and the inlet of the hot water pipe 3. The third temperature sensor 11c collects the temperature of the water purifier's outlet and transmits it to the controller. The controller can determine whether to activate the heating element 5 or the cooler 4 based on the water purifier's outlet temperature and the user-input set temperature. In other words, when the water purifier's outlet temperature matches the set temperature, the cooler 4 and the heating element 5 do not need to be activated.

[0054] In one embodiment, such as Figure 4 As shown, the water purification auxiliary device also includes a water pump 12, which is installed at the inlet of the hot water pipe 3 and the inlet of the cold water pipe 2, and connected to a controller. The water pump 12 drives the water in the pipes, increasing the flow rate. By installing the water pump 12 at the inlet of the hot water pipe 3 and the inlet of the cold water pipe 2, the water flow in these pipes is driven, increasing the water pressure and ensuring smooth water flow. The controller can be connected to the water pump 12 and adjust its driving power to regulate the water pressure and flow rate. Furthermore, the water pump 12 can also pressurize the cold water return pipe 7 and the hot water return pipe 9 to ensure the reliable operation of the water purification auxiliary device. Optionally, the water pump 12 is a DC inverter pump.

[0055] Furthermore, the controller can also be connected to the cold water reversing valve 6 and the hot water reversing valve 8, enabling adjustment of their conduction directions. The controller can also be connected to the inlet solenoid valve, controlling its opening and closing status. This enhances the convenience and reliability of the water purification auxiliary device.

[0056] In one embodiment, the water purification auxiliary device further includes a water tank, which is located at the inlet of the ambient temperature pipeline 1, the inlet of the cold water pipeline 2, and the inlet of the hot water pipeline 3, and is connected to the water purifier. The water tank may be equipped with a sterilization device, such as an LED ultraviolet sterilization device or a quantum sterilization device, to sterilize the purified water and the interior of the water tank. A level sensor connected to a controller may also be installed in the water tank to monitor the water level. Furthermore, a drive pump may be installed between the water tank and the inlets of the ambient temperature pipeline 1, the cold water pipeline 2, and the hot water pipeline 3, capable of drawing water from the water tank to these inlets. In this embodiment, the water tank can store water output from the water purifier, ensuring purified water output when the water purifier malfunctions or experiences a water outage, thus improving the applicability of the water purification auxiliary device.

[0057] Based on the same technical concept, this application also provides a water purification device, which includes a water purifier and a water purification auxiliary device as described in the above embodiments, wherein the water purifier and the water purification auxiliary device are connected. Further, the water purification device may also include a faucet connected to the water purification auxiliary device.

[0058] To better understand the above solution, a detailed explanation will be provided below with reference to a specific embodiment.

[0059] In one embodiment, such as Figure 4 As shown, the water purification equipment includes a water purifier, a faucet, and auxiliary purification devices. The auxiliary devices include a normal temperature water pipe 1, a cold water water pipe 2, a hot water water pipe 3, a chiller 4, a heating element 5, a cold water reversing valve 6, a cold water return pipe 7, a hot water reversing valve 8, a hot water return pipe 9, a normal temperature water solenoid valve 10a, a temperature regulating solenoid valve 10b, a first temperature sensor 11a, a second temperature sensor 11b, a third temperature sensor 11c, a water pump 12, a water tank, a drive pump, a zero-pressure valve, and a controller. The zero-pressure valve is located at the inlet of both the cold water pipe 2 and the hot water pipe 3 to prevent excessive pressure from causing safety accidents. The auxiliary purification devices can also include an overheat protection relay, such as a thermistor or a fuse, at the heating element 5. This relay provides safety protection when the second temperature sensor 11b detects excessively high temperatures in the hot water pipe 3. The heating element 5 can be a heating element capable of rapidly responding to temperature changes, such as a PTC heater or an electromagnetic heater. Optionally, the temperature regulating solenoid valve 10b can also be replaced by a hot water solenoid valve and a cold water solenoid valve respectively installed on the hot water pipe 3 and the cold water pipe 2, wherein the hot water solenoid valve is installed at the inlet of the hot water pipe 3 and the cold water solenoid valve is installed at the inlet of the cold water pipe 2.

[0060] All connections in the water purification auxiliary device are detachable, allowing users to easily adjust the device's structure. The auxiliary device may also include a display element connected to the controller, capable of displaying various parameters of the auxiliary device, such as temperature and running time.

[0061] Based on the combined treatment of purified water by auxiliary water purification devices and water purifiers, the purified water can be dispensed directly as room temperature water, or it can be heated or cooled into hot or ice water before being dispensed to meet users' different drinking temperature needs. When hot water is needed, the water pump 12 is started, the hot water solenoid valve is opened, the heating element 5 is started, and the cooler 4, the cold water solenoid valve, and the room temperature water solenoid valve 10a are all closed. At this time, the hot water reversing valve 8 opens the hot water return pipe 9 and the heating element 5 to heat the hot water. Then, after a set time, the hot water reversing valve 8 opens the heating element 5 and the hot water pipe 3, and the user can turn on the tap to get hot water.

[0062] In this embodiment, users can enjoy the convenience of purified water heating and cooling without replacing the entire machine, saving costs and time. Users can adjust the water temperature at any time according to their personal needs, meeting diverse water temperature requirements in different scenarios and improving the user experience. By setting up a room temperature pipe 1 that can output room temperature water, a hot water pipe 2 that can output hot water, and a cold water pipe 3 that can output cold water, the water purifier can provide water at different temperatures to the faucet, making up for the functional deficiencies of the water purifier, which is conducive to meeting different water needs of users and improving ease of use.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
