In addition, in the description of the present embodiment, unless otherwise specified, the meaning of "plurality" is two or more.

[0054] Example 1

[0055] Figure 1 This is a structural schematic diagram of a water-using device provided in Example 1 of the present disclosure, wherein 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 water outlet valve 106, a second water outlet valve 107, a third water outlet valve 108, a first water outlet 109 and a second water outlet 110; the heat exchanger 103 includes a water pipe 111 and a heat exchange pipe 112, and the controller is electrically connected to the first water pump 104, the second water pump 105, the first water outlet valve 106, the second water outlet valve 107 and the third water outlet valve 108, respectively.

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

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

[0058] The water inlet end of the water pipe 111 is connected to the water outlet end of the second water pump 105, the first water outlet end of the water pipe 111 is connected to one end of the third water outlet valve 108, the other end of the third water outlet valve 108 is connected to the second water outlet 110, and one end of the second water outlet valve 107 is connected to the water inlet end of the temperature control unit 102; the second water outlet end of the water pipe 111 is connected to the other end of the second water 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 temperature of the water in the water pipe reaches the preset temperature and the water in the temperature control unit that has been temperature-controlled reaches the preset temperature, the first water outlet valve and the third water outlet valve are opened at the same time, so that water can be discharged from the first water outlet and the second water outlet at the same time, thereby increasing the water flow rate; and by controlling the second water outlet valve to open, the water in the water pipe whose temperature has not reached the preset temperature can flow back into the temperature control unit for temperature control, thereby increasing the speed of temperature control of the water flow in the water-using equipment, thereby increasing the water flow rate and improving the user's water use experience.

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

[0061] In a specific implementation, the outer layer of the heat exchanger can be covered with multiple layers of insulation materials, such as aluminum foil and polyurethane insulation materials. The aluminum foil can reduce heat radiation, thereby reducing energy loss; the polyurethane insulation material outside the aluminum foil has low heat loss, making the entire heat exchanger have an excellent insulation effect. In practical applications, it is also necessary to periodically inject water into the heat exchange pipes in the heat exchanger to ensure the cold / hot temperature in the heat exchange pipes. In a specific example, water injection can be triggered according to a time interval, or it can be triggered according to whether the water flow temperature in the heat exchange pipe is lower than or higher than a certain temperature.

[0062] In an optional embodiment, Figure 2 As shown, the water-using device further 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 water 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, the water in the water tank is discharged through the third water outlet by default. If the water in the water tank is room temperature water, the third water outlet discharges room temperature water.

[0063] In an optional embodiment, the temperature control unit 102 is a heating unit, which is 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 temperature for water use, the water in the water tank flows into the heating unit through the first water pump for heating. When the heating unit heats the inflowing water to the preset temperature, the first water outlet valve is controlled to open, and water flows out of the hot water outlet; at the same time, the water in the water tank flows into the water pipe of the heat exchanger through the second water pump.

[0064] When the water flow temperature in the heat exchange pipe of the heat exchanger is not enough to raise the normal temperature water in the water pipe to the preset temperature, the second water outlet valve is controlled to open, and the warm water in the water pipe flows out from the first water outlet and then flows into the heating unit through the second water outlet valve for reheating, thereby reducing the time required for heating; when the water flow temperature in the heat exchange pipe of the heat exchanger can heat the normal temperature water in the water pipe to the preset temperature, the third water outlet valve is controlled to open. At this time, since the heating unit heats the water flowing into it to the preset temperature, the first water outlet valve is controlled to open, so that the warm water outlet and the hot water outlet discharge water together, greatly increasing the water outlet flow rate of the hot water.

[0065] In another optional embodiment, the temperature control unit 102 is a refrigeration unit, which is specifically used to cool 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 and cold water outlet. After the user sets the preset temperature for water use, the water in the water tank flows into the refrigeration unit through the first water pump for refrigeration. When the refrigeration unit cools the inflowing water to the preset temperature, the first water outlet valve is controlled to open, and water flows out of the cold water outlet; at the same time, it flows into the water pipe of the heat exchanger through the second water pump.

[0066] When the water flow temperature in the heat exchange pipe of the heat exchanger is not enough to reduce the normal temperature water in the water pipe to the preset temperature, the second water outlet valve is controlled to open, and the warm and cold water in the water pipe flows out from the first water outlet end and then flows into the refrigeration unit from the water inlet end of the refrigeration unit through the second water outlet valve for re-refrigeration, thereby reducing the time required for refrigeration; when the water flow temperature in the heat exchange pipe of the heat exchanger can cool the normal temperature water in the water pipe to the preset temperature, the third water outlet valve is controlled to open. At this time, since the heating unit heats the water flowing into it to the preset temperature, the first water outlet valve is controlled to open, so that the warm and cold water outlet and the cold water outlet discharge water together, greatly increasing the water outlet flow rate of the cold water.

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

[0068] In this embodiment, when the water flow temperature in the heat exchange pipe is not enough to reach the preset temperature of the water flow temperature in the water pipe, the controller controls the control valve to open, controls the first water outlet valve to close, and changes the water in the heat exchange pipe to provide energy for periodic heat exchange, so that the water in the water pipe quickly reaches the preset temperature by using the energy of the water in the heat exchange pipe, thereby greatly increasing the water flow rate and improving the user's water experience. In addition, the water outlet end of the heat exchange pipe is connected to the drain port. Before changing the water, the drain port is controlled to open to discharge the residual water in the heat exchange pipe.

[0069] This embodiment also provides a water output control method for water-using equipment. Figure 4 A flow chart of a water outlet control method provided in this embodiment is applied to the above-mentioned water-using equipment. The water outlet control method comprises the following steps:

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

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

[0072] S402: Control the temperature control unit to perform temperature control on the inflowing water at the preset temperature.

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

[0074] S403: In response to the temperature-controlled water in the temperature control unit reaching the preset temperature, control the first water outlet valve to open.

[0075] S404, determining whether the temperature of the water in the water pipe reaches the preset temperature, if so, executing step S405, if not, executing step S406.

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

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

[0078] In this embodiment, when the temperature of the water in the water pipe reaches the preset temperature and the water in the temperature control unit that has been temperature-controlled reaches the preset temperature, the first water outlet valve and the third water outlet valve are opened at the same time, so that water can be discharged from the first water outlet and the second water outlet at the same time, thereby increasing the water flow rate; and by controlling the second water outlet valve to open, the water in the water pipe whose temperature has not reached the preset temperature can flow back into the temperature control unit for temperature control, thereby increasing the speed of temperature control of the water flow in the water-using equipment, thereby increasing the water flow rate and improving the user's water use experience.

[0079] In an optional embodiment, Figure 5 As shown, the water outlet control method further includes the following steps:

[0080] S501 . In response to satisfying a water injection trigger condition, controlling the temperature control unit to perform temperature control on the inflowing water at a target temperature.

[0081] S502: In response to the temperature-controlled water in the temperature control unit reaching the target temperature, control the control valve between the temperature control unit and the heat exchange pipe to open, and control the first water outlet valve to close, so as to re-inject water for heat exchange into the heat exchange pipe.

[0082] In this embodiment, when the water flow temperature in the heat exchange pipe is not enough to reach the preset temperature, the control valve is opened to exchange water in the heat exchange pipe. In a specific example, the temperature control unit is controlled to control the temperature of the incoming water to the target temperature, and other independent temperature control units can also be set to control the temperature of the incoming water to the target temperature.

[0083] In an optional embodiment, the water injection trigger condition is that this water injection is the first water injection. In this embodiment, when the water-using device 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, and the controller controls the control valve to open to inject water into the heat exchange pipe.

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

[0085] In this embodiment, the water injection trigger condition is that the time from the last water injection reaches a preset time, that is, the water injection is triggered according to the time interval. When the time from the last water injection reaches the preset time, the controller controls the control valve to open and the first water outlet valve to close, and the water in the heat exchange pipe is replaced. In addition, the water outlet of the heat exchange pipe is connected to the drain port. Before the water is replaced, the drain port is controlled to open to discharge the residual water in the heat exchange pipe.

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

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

[0088] In an 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 a replacement temperature at which the water in the water pipe can reach a preset temperature. When it is detected that the temperature of the water in the heat exchange pipe is higher than the second temperature, the water injection trigger condition is triggered, and the controller controls the control valve to open and the first water outlet valve to close to replace the water in the heat exchange pipe. In addition, the water outlet end of the heat exchange pipe is connected to the drain port. Before replacing the water, the drain port is controlled to open to discharge the residual water in the heat exchange pipe.

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

[0091] In this embodiment, when the user needs to use water but has not set a preset temperature, that is, the second water use instruction is to need water but not set a preset temperature, the fourth water outlet valve connected to the water outlet of the second water pump is controlled to open, and the water in the water tank flows through the second water pump and the fourth water outlet valve and then flows out through the third water outlet. It should be noted that if the water in the water tank is room temperature water, the water flowing out of the third water outlet is room temperature water.

[0098] The water inlet end of the second water pipe 621 is connected to the water outlet end of the second water pump 607, the third water outlet end of the second water pipe 621 is connected to one end of the fifth water outlet valve 612, the other end of the fifth water outlet valve 612 is connected to the fourth water outlet 617, and one end of the sixth water outlet valve 613 is connected to the water inlet end of the refrigeration unit 603; the fourth water outlet end of the second water pipe 621 is connected to the other end of the sixth water 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 water outlet is a hot water outlet, and the second water outlet is a warm water outlet. After the user sets the preset temperature of the water, the water in the water tank flows into the heating unit through the first water pump for heating. When the heating unit heats the water flowing in to the preset temperature, the first water outlet valve is controlled to open, and the hot water outlet flows out; at the same time, it flows into the first water pipe of the first heat exchanger through the second water pump. When the water flow temperature in the first heat exchange pipe is not enough to raise the normal temperature water in the first water pipe to the preset temperature, the second water outlet valve is controlled to open, so that the warm water in the first water pipe flows out from the first water outlet end and then passes through the second water outlet valve and flows into the heating unit from the water inlet end of the heating unit for reheating, thereby reducing the time required for heating; when the water flow temperature in the first heat exchange pipe can heat the normal temperature water in the first water pipe to the preset temperature, the third water outlet valve is controlled to open.

After the user sets the preset temperature of the water, the water in the water tank flows into the refrigeration unit through the first water pump for refrigeration. When the refrigeration unit cools the water flowing in to the preset temperature, the seventh water outlet valve is controlled to open, and the cold water outlet is discharged; at the same time, it flows into the second water pipe of the second heat exchanger through the second water pump. When the water flow temperature in the second heat exchange pipe is not enough to reduce the normal temperature water in the second water pipe to the preset temperature, the sixth water outlet valve is controlled to open, so that the warm and cold water in the second water pipe flows out from the third water outlet end and then passes through the sixth water outlet valve and flows into the refrigeration unit from the water inlet end of the refrigeration unit for re-refrigeration, thereby reducing the time required for refrigeration; when the water flow temperature in the second heat exchange pipe can cool the normal temperature water in the second water pipe to the preset temperature, the fifth water outlet valve is controlled to open.

The temperature control of the heat exchanger in the water-using equipment is realized according to the position PID algorithm, wherein the specific calculation formula is:

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

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

[0107] In this embodiment, when the water flow temperature in the first heat exchange pipe is not high enough to make the water flow temperature in the first water pipe reach the preset temperature, the controller controls the first control valve to open and controls the first water outlet valve to close, and changes the water in the first heat exchange pipe to provide energy for periodic heat exchange, so that the water in the first water pipe can quickly reach the preset temperature by using the energy of the water in the first heat exchange pipe, thereby greatly improving the water outlet flow rate and improving the user's water use experience; in addition, the water outlet end of the first heat exchange pipe is connected to the drain port.
