Description

Technical Field

[0001] This utility model relates to the field of water-using equipment, and in particular to a water-using equipment. Background Technology

[0002] In existing water purifiers, the output of warm water is generally achieved by mixing hot and cold water.

If the interval between two water extractions is long, the water remaining in the heat exchange tubes will cool down, affecting user experience. Utility Model Content

[0038] In this embodiment of the invention, prefixes such as "first" and "second" are used merely to distinguish different descriptive objects and do not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes to distinguish descriptive objects in this embodiment of the invention does not constitute a limitation on the described objects.

Furthermore, in the description of this embodiment, unless otherwise stated, "multiple" means two or more.

[0039] Example 1

[0040] Figure 1 This is a schematic diagram of a water-using device provided in an embodiment of the present invention. 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] In one alternative embodiment, the water-using equipment further includes a first temperature sensor electrically connected to the controller for detecting the water flow temperature in the water-using pipe.

[0048] In one alternative embodiment, the water-using equipment further includes a second temperature sensor electrically connected to the controller for detecting the water flow temperature in the heat exchange pipe.

[0049] In this embodiment, the temperature control of the heat exchanger in the water-using equipment is achieved based on a positional PID algorithm, wherein the specific calculation formula is as follows:

[0050] U(t)=Kp×e(t)+Ki×Σe(t)+Kd×(e(t)-e(t-1))

[0051] Wherein, U(t) is the energy of the difference between the water flow temperature and the preset temperature in the heat exchange pipe in the heat exchanger; e(t) is the difference between the preset temperature and the water flow temperature in the 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.

[0052] In one alternative embodiment, such as Figure 2As 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 has not set a preset temperature, the fourth water outlet valve connected to the outlet of the second water pump is opened, and the water in the water tank flows through the second water pump and the fourth water outlet valve before flowing out through the third water outlet. It should be noted that if the water in the water tank is at room temperature, then the water flowing out of the third water outlet is also at room temperature.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] In one alternative embodiment, such as Figure 4 As shown, the water-using equipment also includes a first one-way valve 401; the inlet of the first one-way valve is connected to the outlet of the temperature control unit, and the outlet of the first one-way valve is connected to the first outlet valve.

[0060] In one alternative embodiment, such as Figure 4 As shown, the water-using equipment also includes a second one-way valve 402, the inlet end of which is connected to the second outlet valve, and the outlet end of which is connected to the inlet end of the temperature control unit.

[0061] In one alternative embodiment, such as Figure 4 As shown, the water-using equipment also includes a third one-way valve 403, the inlet of which is connected to the outlet of the second water pump, and the outlet of which is connected to the inlet of the water-using pipe.

[0062] In this embodiment, by setting a first one-way valve, water flowing out of the temperature control unit can be prevented from flowing back into the temperature control unit; by setting a second one-way valve, water flowing out of the first water pump can be prevented from flowing back into the second outlet end of the water pipe when the second outlet valve is open; by setting a third one-way valve, water in the water pipe can be prevented from flowing back out from the inlet end of the water pipe.

[0070] 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.

[0071] 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.

In a specific example, the temperature control of the heat exchanger in the water-using equipment is implemented according to a positional PID algorithm, wherein the specific calculation formula is as follows:

[0075] U(t)=Kp×e(t)+Ki×Σe(t)+Kd×(e(t)-e(t-1))

[0076] 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.

[0078] 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.
