Description

Technical Field

[0002] In existing water purifiers, the output of warm water is generally achieved by mixing hot and cold water. This limits the flow rate of warm water, resulting in a relatively small flow that cannot meet people's regular needs. Traditional water purifiers typically use heat exchange to produce warm water, requiring hot and cold water to exchange heat in heat exchange tubes. If the interval between two water extractions is long, the water remaining in the heat exchange tubes will cool down, affecting user experience. Summary of the Invention

[0054] Example 1

[0055] Figure 1 This is a schematic diagram of a water-using device provided in Embodiment 1 of this disclosure. The water-using device includes a controller (not shown in the figure), a water tank 101, a temperature control unit 102, a heat exchanger 103, a first water pump 104, a second water pump 105, a first outlet valve 106, a second outlet valve 107, a third outlet valve 108, a first outlet 109, and a second outlet 110. The heat exchanger 103 includes a water pipe 111 and a heat exchange pipe 112. The controller is electrically connected to the first water pump 104, the second water pump 105, the first outlet valve 106, the second outlet valve 107, and the third outlet valve 108, respectively.

[0056] The outlet of the water tank 101 is connected to the inlet of the first water pump 104 and the inlet of the second water pump 105, respectively.

[0057] The inlet of the temperature control unit 102 is connected to the outlet of the first water pump 104, and the outlet of the temperature control unit 102 is connected to one end of the first outlet valve 106. The other end of the first outlet valve 106 is connected to the first outlet 109. The temperature control unit 102 is used to control the temperature of the incoming water.

[0058] The inlet end of the water pipe 111 is connected to the outlet end of the second water pump 105. The first outlet end of the water pipe 111 is connected to one end of the third outlet valve 108. The other end of the third outlet valve 108 is connected to the second outlet 110. One end of the second outlet valve 107 is connected to the inlet end of the temperature control unit 102. The second outlet end of the water pipe 111 is connected to the other end of the second outlet valve 107. The water injected into the heat exchange pipe 112 is used to exchange heat with the water in the water pipe 111.

[0059] In this embodiment, when the water temperature in the water pipe reaches the preset temperature and the temperature-controlled water in the temperature control unit reaches the preset temperature, the first outlet valve and the third outlet valve open simultaneously, allowing water to flow from the first outlet and the second outlet at the same time, increasing the water flow rate. Furthermore, by controlling the second outlet valve to open, water in the water pipe that has not reached the preset temperature flows back into the temperature control unit for temperature control, increasing the speed at which the water flow in the water-using equipment is temperature-controlled, thereby increasing the water flow rate and improving the user's water usage experience.

[0060] In a specific example, the water-using device can be applied to a water purifier. Water purified by the water purifier can be passed through the water-using device provided in this embodiment to obtain water at the preset temperature required by the user.

[0061] In practical implementation, the heat exchanger's outer layer can be covered with multiple layers of insulation material, such as aluminum foil and polyurethane insulation. The aluminum foil reduces heat radiation, thereby reducing energy loss; the polyurethane insulation material outside the aluminum foil has low heat loss, giving the entire heat exchanger excellent insulation properties. In practical applications, it is also necessary to periodically inject water into the heat exchange pipes within the heat exchanger to maintain the cold / hot temperatures within the pipes. In a specific example, water injection can be triggered based on time intervals or based on whether the water temperature within the heat exchange pipes is below or above a certain temperature.

[0062] In one alternative embodiment, such as Figure 2 As shown, the water-using equipment also includes a fourth water outlet valve 201 and a third water outlet 202. The fourth water outlet valve 201 is electrically connected to the controller. One end of the fourth water outlet valve 201 is connected to the outlet of the second water pump 105, and the other end is connected to the third water outlet 202. In this embodiment, when the user uses water but does not set a preset temperature, water from the water tank is discharged through the third water outlet by default. If the water in the water tank is at room temperature, then room temperature water is discharged from the third water outlet.

[0063] In one optional embodiment, the temperature control unit 102 is a heating unit, specifically used to heat water. In this embodiment, the temperature control unit is a heating unit, the first water outlet is a hot water outlet, and the second water outlet is a warm water outlet. After the user sets the preset water temperature, the water in the water tank flows into the heating unit for heating via the first water pump. When the heating unit heats the incoming water to the preset temperature, it controls the first water outlet valve to open, and water flows out of the hot water outlet; simultaneously, the water in the water tank flows into the water pipe of the heat exchanger via the second water pump.

[0064] When the water temperature in the heat exchanger's heat exchange pipes is insufficient to raise the ambient temperature water in the water pipes to the preset temperature, the second outlet valve is opened, allowing the warm water in the water pipes to flow out from the first outlet and then through the second outlet valve into the heating unit for reheating, reducing the heating time. When the water temperature in the heat exchanger's heat exchange pipes can heat the ambient temperature water in the water pipes to the preset temperature, the third outlet valve is opened. At this time, since the heating unit heats the water flowing into it to the preset temperature, the first outlet valve is opened, allowing the warm and hot water outlets to discharge water simultaneously, greatly increasing the hot water flow rate.

[0065] In an alternative embodiment, the temperature control unit 102 is a refrigeration unit, specifically used to cool the water. In this embodiment, the temperature control unit is a refrigeration unit, the first water outlet is a cold water outlet, and the second water outlet is a warm / cold water outlet. After the user sets the preset water temperature, the water in the water tank flows into the refrigeration unit for cooling via the first water pump. When the refrigeration unit cools the incoming water to the preset temperature, it controls the first water outlet valve to open, and water flows out of the cold water outlet; simultaneously, it flows into the water pipe of the heat exchanger via the second water pump.

[0066] When the water temperature in the heat exchanger's heat exchange pipes is insufficient to lower the ambient temperature water in the water pipes to the preset temperature, the second outlet valve is opened. The warm or cold water in the water pipes flows out from the first outlet and then through the second outlet valve into the refrigeration unit for further cooling, reducing the cooling time. When the water temperature in the heat exchanger's heat exchange pipes can cool the ambient temperature water in the water pipes to the preset temperature, the third outlet valve is opened. At this time, since the heating unit heats the water flowing into it to the preset temperature, the first outlet valve is opened, so that the warm and cold water outlets and the cold water outlet both discharge water, greatly increasing the flow rate of cold water.

[0067] In one alternative embodiment, such as Figure 3 As shown, the water-using equipment also includes a control valve 301, which is electrically connected to the controller. One end of the control valve 301 is connected to the inlet end of the heat exchange pipe 112, and the other end is connected to the outlet end of the temperature control unit 102.

[0068] In this embodiment, when the water temperature in the heat exchange pipe is insufficient to reach the preset temperature in the water supply pipe, the controller opens the control valve and closes the first outlet valve to replace the water in the heat exchange pipe. This provides energy for periodic heat exchange, allowing the water in the water supply pipe to quickly reach the preset temperature using the energy from the water in the heat exchange pipe, thereby greatly increasing the water flow rate and improving the user's water experience. Additionally, the outlet of the heat exchange pipe is connected to a drain. Before replacing the water, the drain is opened to remove any residual water from the heat exchange pipe.

[0069] This embodiment also provides a method for controlling the water output of a water-using device. Figure 4 A flowchart of a water outlet control method provided in this embodiment, applied to the above-mentioned water-using equipment, is included in the following steps:

[0070] S401. In response to a first water usage command, control the first water pump and the second water pump to start, wherein the first water usage command includes a preset temperature.

[0071] In this embodiment, the first water usage command can be issued after the user sets a preset temperature, for example, by pressing a corresponding button or triggering a corresponding icon on the screen after setting the preset temperature.

[0072] S402. Control the temperature control unit to control the inflowing water to the preset temperature.

[0073] In this embodiment, the temperature control unit can be a heating unit or a cooling unit. When the temperature control unit is a heating unit, it is used to heat the incoming water to a preset temperature; when the temperature control unit is a cooling unit, it is used to cool the incoming water to a preset temperature.

[0074] S403. In response to the water in the temperature control unit reaching the preset temperature, the first water outlet valve is opened.

[0075] S404. Determine whether the temperature of the water in the water pipe has reached the preset temperature. If yes, proceed to step S405; otherwise, proceed to step S406.

[0076] S405, Control the third outlet valve to open.

[0077] S406, Control the second outlet valve to open.

[0078] In this embodiment, when the water temperature in the water pipe reaches the preset temperature and the temperature-controlled water in the temperature control unit reaches the preset temperature, the first outlet valve and the third outlet valve open simultaneously, allowing water to flow from the first outlet and the second outlet at the same time, increasing the water flow rate. Furthermore, by controlling the second outlet valve to open, water in the water pipe that has not reached the preset temperature flows back into the temperature control unit for temperature control, increasing the speed at which the water flow in the water-using equipment is temperature-controlled, thereby increasing the water flow rate and improving the user's water usage experience.

[0079] In one alternative embodiment, such as Figure 5 As shown, the water outlet control method further includes the following steps:

[0080] S501. In response to the water injection triggering condition being met, the temperature control unit is controlled to perform temperature control on the incoming water at the target temperature.

[0081] S502, in response to the water in the temperature control unit reaching the target temperature, the control valve located between the temperature control unit and the heat exchange pipe is opened, and the first outlet valve is closed, so as to re-inject water for heat exchange into the heat exchange pipe.

[0082] In this embodiment, if the water temperature in the heat exchange pipe is insufficient to reach the preset temperature in the water supply pipe, the control valve is opened to replace the water in the heat exchange pipe. In a specific example, the temperature control unit controls the incoming water to the target temperature; alternatively, a separate temperature control unit can be used to control the incoming water to the target temperature.

[0083] In one optional embodiment, the water injection trigger condition is that this water injection is the first water injection. In this embodiment, when the water-using equipment is triggered for the first time, for example, when the power is turned on for the first time, the water injection trigger condition is triggered, the controller controls the control valve to open, and water is injected into the heat exchange pipeline.

[0084] In one optional embodiment, the water injection trigger condition is that the time elapsed since the last water injection reaches a preset time.

[0085] In this embodiment, the water injection trigger condition is that the time elapsed since the last water injection reaches a preset time, i.e., water injection is triggered according to a time interval. When the preset time elapsed since the last water injection, the controller controls the control valve to open and the first outlet valve to close, thereby replacing the water in the heat exchange pipeline. In addition, the outlet end of the heat exchange pipeline is connected to a drain port. Before replacing the water, the drain port is opened to drain any residual water in the heat exchange pipeline.

[0086] In one optional embodiment, when the temperature control unit is a heating unit, the water injection trigger condition is that the temperature of the water in the heat exchange pipe is lower than a first temperature.

[0087] In this embodiment, the first temperature is the replacement temperature at which the water in the heat exchange pipe can reach a preset temperature. When the temperature of the water in the heat exchange pipe is detected to be lower than the first temperature, the water injection trigger condition is triggered, the controller controls the control valve to open and the first outlet valve to close, thereby replacing the water in the heat exchange pipe. In addition, the outlet end of the heat exchange pipe is connected to a drain port. Before replacing the water, the drain port is opened to drain the residual water in the heat exchange pipe.

[0088] In one optional embodiment, when the temperature control unit is a refrigeration unit, the water injection trigger condition is that the temperature of the water in the heat exchange pipe is higher than the second temperature.

[0089] In this embodiment, the second temperature is the replacement temperature at which the water in the heat exchange pipe can reach a preset temperature. When the temperature of the water in the heat exchange pipe is detected to be higher than the second temperature, the water injection trigger condition is triggered, the controller controls the control valve to open and the first outlet valve to close, thereby replacing the water in the heat exchange pipe. In addition, the outlet end of the heat exchange pipe is connected to a drain port. Before replacing the water, the drain port is opened to drain the residual water in the heat exchange pipe.

[0090] In one optional embodiment, the water outlet control method further includes the following steps: in response to a second water usage command, controlling the second water pump and a fourth water outlet valve connected to the outlet end of the second water pump to open.

[0091] In this embodiment, when a user needs water but has not set a preset temperature (i.e., the second water usage command is "need water but not set a preset temperature"), the fourth outlet valve connected to the outlet of the second water pump is opened. Water from the tank flows through the second water pump and the fourth outlet valve, then exits through the third outlet. It should be noted that if the water in the tank is at room temperature, then the water flowing from the third outlet will also be at room temperature.

The unit includes a heating unit 602 and a cooling unit 603. The first heat exchanger 604 includes a first water pipe 619 and a first heat exchange pipe 620. The second heat exchanger 605 includes a second water pipe 621 and a second heat exchange pipe 622. The controller is electrically connected to the first water pump 606, the second water pump 607, the third water pump 608, the first outlet valve 609, the second outlet valve 610, the third outlet valve 611, the fifth outlet valve 612, the sixth outlet valve 613, and the seventh outlet valve 614, respectively.

[0094] The outlet of the water tank 601 is connected to the inlet of the first water pump 606, the inlet of the second water pump 607, and the inlet of the third water pump 608, respectively.

[0095] The inlet of the heating unit 602 is connected to the outlet of the first water pump 606, and the outlet of the heating unit 602 is connected to one end of the first outlet valve 609. The other end of the first outlet valve 609 is connected to the first outlet 615. The heating unit 602 is used to heat the incoming water.

[0096] The inlet end of the first water pipe 619 is connected to the outlet end of the second water pump 607, the first outlet end of the first water pipe 619 is connected to one end of the third outlet valve 611, the other end of the third outlet valve 611 is connected to the second outlet 616, one end of the second outlet valve 610 is connected to the inlet end of the heating unit 602, the second outlet end of the first water pipe 619 is connected to the other end of the second outlet valve 610, and the water injected into the first heat exchange pipe 620 is used to exchange heat with the water in the first water pipe 619.

[0097] The inlet of the refrigeration unit 603 is connected to the outlet of the third water pump 608, and the outlet of the refrigeration unit 603 is connected to one end of the seventh outlet valve 614. The other end of the seventh outlet valve 614 is connected to the fifth outlet 618. The refrigeration unit 603 is used to refrigerate the incoming water.

[0098] The inlet end of the second water pipe 621 is connected to the outlet end of the second water pump 607, the third outlet end of the second water pipe 621 is connected to one end of the fifth outlet valve 612, the other end of the fifth outlet valve 612 is connected to the fourth outlet 617, and one end of the sixth outlet valve 613 is connected to the inlet end of the refrigeration unit 603; the fourth outlet end of the second water pipe 621 is connected to the other end of the sixth outlet valve 613; the water injected into the second heat exchange pipe 622 is used to exchange heat with the water in the second water pipe 621.

[0099] In this embodiment, the first outlet is a hot water outlet, and the second outlet is a warm water outlet. After the user sets the preset water temperature, water in the tank flows into the heating unit via the first water pump for heating. When the heating unit heats the incoming water to the preset temperature, it controls the first outlet valve to open, and water flows out of the hot water outlet. Simultaneously, water flows through the second water pump into the first water pipe of the first heat exchanger. When the water temperature in the first heat exchange pipe is insufficient to raise the ambient temperature water in the first water pipe to the preset temperature, it controls the second outlet valve to open, allowing the warm water in the first water pipe to flow out from the first outlet end, then through the second outlet valve, and into the heating unit from the inlet end for reheating, reducing the heating time. When the water temperature in the first heat exchange pipe can heat the ambient temperature water in the first water pipe to the preset temperature, it controls the third outlet valve to open. At this time, since the heating unit heats the incoming water to the preset temperature, it controls the first outlet valve to open, thus allowing the warm water outlet and the hot water outlet to both outlet out, greatly increasing the hot water flow rate.

[0100] In this embodiment, the fifth outlet is a cold water outlet, and the fourth outlet is a warm / cold water outlet. After the user sets the preset water temperature, water in the water tank flows into the refrigeration unit for cooling via the first water pump. When the refrigeration unit cools the incoming water to the preset temperature, the seventh outlet valve is opened, and water flows out of the cold water outlet. Simultaneously, water flows through the second water pump into the second water pipe of the second heat exchanger. When the water temperature in the second heat exchange pipe is insufficient to lower the ambient temperature water in the second water pipe to the preset temperature, the sixth outlet valve is opened, allowing the warm / cold water in the second water pipe to flow out from the third outlet, pass through the sixth outlet valve, and flow into the refrigeration unit from the inlet for further cooling, reducing the cooling time. When the water temperature in the second heat exchange pipe can cool the ambient temperature water in the second water pipe to the preset temperature, the fifth outlet valve is opened. At this time, since the refrigeration unit cools the incoming water to the preset temperature, the seventh outlet valve is opened, allowing water to flow out from both the warm / cold water outlet and the cold water outlet, greatly increasing the flow rate of cold water.

[0101] In one optional embodiment, the water-using device further includes a first temperature sensor and a third temperature sensor electrically connected to the controller, wherein the first temperature sensor is used to detect the water flow temperature in the first water-using pipe, and the third temperature sensor is used to detect the water flow temperature in the second water-using pipe.

[0102] In one optional embodiment, the water-using equipment further includes a second temperature sensor and a fourth temperature sensor electrically connected to the controller, wherein the second temperature sensor is used to detect the water flow temperature in the first heat exchange pipe, and the fourth temperature sensor is used to detect the water flow temperature in the second heat exchange pipe.

[0103] In this embodiment, a first temperature sensor is used to detect the water temperature in the first water pipe, a third temperature sensor is used to detect the water temperature in the second water pipe, a second temperature sensor is used to detect the water temperature in the first heat exchange pipe, and a fourth temperature sensor is used to detect the water temperature in the second heat exchange pipe. Temperature control of the heat exchanger in the water-using equipment is achieved using a positional PID algorithm, wherein the specific calculation formula is as follows:

[0104] U(t)=Kp×e(t)+Ki×Σe(t)+Kd×(e(t)-e(t-1))

[0105] Wherein, U(t) is the energy of the difference between the water flow temperature and the preset temperature of a certain heat exchange pipe in the heat exchanger; e(t) is the difference between the preset temperature and the water flow temperature of a certain heat exchange pipe, that is, the preset temperature minus the water flow temperature; e(t-1) is the temperature difference calculated after the last test; Kp, Ki, and Kd are set coefficients, which are obtained by conducting multiple heat exchange experiments based on the preset temperature and the temperature after water flow.

[0106] In one alternative embodiment, such as Figure 6 As shown, the water-using equipment also includes a first control valve 623 and a second control valve 624, both of which are electrically connected to the controller; one end of the first control valve 623 is connected to the inlet of the first heat exchange pipe 620, and the other end is connected to the outlet of the heating unit 602; one end of the second control valve 624 is connected to the inlet of the second heat exchange pipe 622, and the other end is connected to the outlet of the refrigeration unit 603.

[0107] In this embodiment, when the water temperature in the first heat exchange pipe is insufficient to reach the preset temperature in the first water supply pipe, the controller controls the first control valve to open and the first outlet valve to close, thereby replacing the water in the first heat exchange pipe and providing energy for periodic heat exchange. This allows the water in the first water supply pipe to quickly reach the preset temperature using the energy of the water in the first heat exchange pipe, thus greatly increasing the water flow rate and improving the user's water experience. In addition, the outlet end of the first heat exchange pipe is connected to the drain outlet. Before replacing the water, the drain outlet is opened to discharge the residual water in the first heat exchange pipe.

[0108] In addition, if the water temperature in the second heat exchange pipe is insufficient to reach the preset temperature in the second water supply pipe, the controller opens the second control valve and closes the seventh outlet valve to replace the water in the second heat exchange pipe, providing energy for periodic heat exchange. This allows the water in the second water supply pipe to quickly reach the preset temperature using the energy of the water in the second heat exchange pipe, thereby greatly increasing the water flow rate and improving the user's water experience. Furthermore, the outlet of the second heat exchange pipe is connected to the drain. Before replacing the water, the drain is opened to discharge any residual water in the second heat exchange pipe.

[0109] In one alternative embodiment, such as Figure 6 As shown, the water-using equipment also includes a fourth water outlet valve 625 and a third water outlet 626. The fourth water outlet valve is electrically connected to the controller, with one end connected to the outlet of the second water pump and the other end connected to the third water outlet. In this embodiment, when the user needs water but has not set a preset temperature, the fourth water outlet valve connected to the outlet of the second water pump is opened, and water from the water tank is discharged through the third water outlet. If the water in the tank is at room temperature, then room temperature water is discharged from the third water outlet.

[0110] Figure 7 The water outlet control method provided in this embodiment 2 is applied to, for example... Figure 7 The water outlet control method for the water-using equipment shown includes the following steps:

[0111] S701. In response to the first water usage command, control the first water pump and the second water pump to start.

[0112] S702. Control the heating unit to heat the incoming water until the preset temperature is reached.

[0113] S703. In response to the water in the heating unit reaching the preset temperature, control the first water outlet valve to open.

[0114] S704. Determine whether the temperature of the water in the first water pipe has reached the preset temperature. If yes, proceed to step S705; otherwise, proceed to step S706.

[0115] S705, Control the opening of the third outlet valve.

[0116] S706, Control the second outlet valve to open.

[0117] S707, in response to the second water usage command, controls the second water pump and the fourth outlet valve connected to the outlet end of the second water pump to open.

[0118] S708. In response to a third water usage command, control the third water pump and the second water pump to start.

[0119] S709. Control the refrigeration unit to cool the incoming water until the preset temperature is reached.

[0120] S710. In response to the water in the refrigeration unit reaching the preset temperature, control the seventh water outlet valve to open.

[0121] S711. Determine whether the temperature of the water in the water pipe has reached the preset temperature. If yes, proceed to step S712; otherwise, proceed to step S713.

[0122] S712. In response to the water temperature in the water pipe reaching the preset temperature, control the fifth water outlet valve to open.

[0123] S713. In response to the fact that the temperature of the water in the water pipe has not reached the preset temperature, control the sixth water outlet valve to open.

[0124] In this embodiment, when the water temperature in the first water pipe reaches the preset temperature, the third water outlet valve is opened. In response to the heated water in the heating unit reaching the preset temperature, the first water outlet valve is opened. At this time, both the first and third water outlet valves open simultaneously, allowing water to flow from the first and second outlets simultaneously, increasing the hot water flow rate. When the water temperature in the second water pipe reaches the preset temperature, the fifth water outlet valve is opened. In response to the cooled water in the cooling unit reaching the preset temperature, the seventh water outlet valve is opened. At this time, both the fifth and seventh water outlet valves open simultaneously, allowing water to flow from the fourth and fifth outlets simultaneously, increasing the cold water flow rate. Furthermore, by opening the second water outlet valve, water in the first water pipe with a temperature lower than the preset temperature flows back into the heating unit for heating. By opening the fifth water outlet valve, water in the second water pipe with a temperature higher than the preset temperature flows back into the cooling unit for cooling. This improves the speed of temperature control in the water-using equipment, thereby increasing the water flow rate and enhancing the user's water experience.
