Description

Technical Field

[0001] The invention relates to a household appliance, and in particular to a purified drinking water temperature control system and a temperature control method. Background Art

[0002] The water purifier is used to filter the raw water and then output pure water. Some water purifiers also have a temperature adjustment function. Such water purifiers are equipped with a cooling module or a heating module at the water outlet. According to the required water outlet temperature, the water outlet of the water purifier is adjusted to the cooling module or the heating module. However, the temperature adjustment efficiency of such water purifiers is low. Every time water of different temperatures needs to be output, the cooling module or the heating module is required to directly adjust the water outlet to the target temperature, resulting in high energy consumption and poor practicality of the whole machine. Therefore, there is an urgent need for a water purifier temperature adjustment system that can better adjust the water outlet temperature. Summary of the invention The purpose of the present invention is to provide a pure drinking water temperature control system and a temperature control method to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0003] The solution of the present invention to solve its technical problem is: The first aspect of the present invention provides a pure drinking water temperature control system, comprising: a water purifier, which has a raw water inlet, a pure water outlet and a concentrated water outlet; a heat exchanger, which has a pure water heat exchange zone, a concentrated water heat exchange zone, a cold water heat exchange zone and a boiling water heat exchange zone separated from each other, the pure water outlet is connected to the pure water heat exchange zone through a pipeline, the concentrated water outlet is connected to the concentrated water heat exchange zone through a pipeline, and the concentrated water heat exchange zone is provided with a concentrated water outlet; an ice tank, which has a first pure water inlet, a second pure water inlet, a first cold water outlet and a second cold water outlet, the first cold water outlet and the first pure water inlet are respectively connected to the cold water heat exchange zone through pipelines, and the second pure water inlet is connected to the boiling water heat exchange zone through a pipeline; a heater, which has a third pure water inlet and a boiling water outlet, the third pure water inlet is connected to the pure water heat exchange zone through a pipeline, and the boiling water outlet is connected to the boiling water heat exchange zone through a pipeline.

[0004] This technical solution has at least the following beneficial effects: the raw water from outside enters the water purifier from the raw water inlet, the raw water is filtered by the water purifier, and the purified pure water is discharged from the pure water outlet to the pure water heat exchange zone of the heat exchanger, and the concentrated water containing impurities after purification is discharged from the concentrated water outlet to the concentrated water heat exchange zone of the heat exchanger. When normal temperature water is needed, the pure water in the pure water heat exchange zone can be directly discharged; when high-temperature pure water is needed, part of the pure water in the pure water heat exchange zone enters the heater from the third pure water inlet through a pipeline, and flows back to the boiling water heat exchange zone after being heated by the heater. The boiling water in the boiling water heat exchange zone exchanges heat with the pure water in the pure water heat exchange zone and the concentrated water in the concentrated water heat exchange zone, so that the pure water is heated and heated before being output, and the boiled hot water is cooled to boiled water after heat exchange, and enters the ice tank from the second pure water inlet for storage; when the temperature of the pure water heating needs to be lowered, the ice tank can also be used to cool the water. The boiled water in the ice tank is input from the first cold water outlet to the cold water heat exchange zone to neutralize the temperature in the boiling water heat exchange zone, thereby reducing the temperature of the pure water output from the pure water heat exchange zone; when cold water needs to be output, low-temperature boiled water can be directly obtained from the second cold water outlet; when the boiled water in the ice tank needs to be reheated, the boiled water in the ice tank can be input into the cold water heat exchange zone, and the temperature is increased after heat exchange with the boiling water heat exchange zone to obtain the reheated boiled water. In this process, pure water is also continuously fed from the pure water heat exchange zone into the heater for heating, and the boiled water obtained after heat exchange in the boiling water heat exchange zone is replenished into the ice tank to realize dynamic circulation and replenishment. In this way, the pure water and boiled water to be output can be temperature-controlled, and the utilization rate of thermal energy is improved by continuous circulation and conversion between pure water, boiling water, boiled water and cold water during the temperature adjustment process, thereby reducing working energy consumption, enriching the overall use function and improving the overall practicality.

[0005] As a further improvement of the above technical solution, the present invention also includes a water mixing and temperature regulating valve, which has a first water mixing inlet, a second water mixing inlet and a water mixing outlet, wherein the first water mixing inlet is connected to the boiling water outlet through a pipeline, and the second water mixing inlet is connected to the boiling water heat exchange zone through a pipeline. When in use, the outputted boiled water can also be temperature-regulated. Specifically, boiled water cooled in the boiling water heat exchange zone is input into the water mixing and temperature regulating valve from the second water mixing inlet, and boiling water heated by the heater is output into the water mixing and temperature regulating valve from the first water mixing inlet, thereby heating boiled water again. The water flow entering from the first water mixing inlet and the second water mixing inlet is controlled by the water mixing and temperature regulating valve itself, thereby realizing outputting boiled water heated again from the water mixing outlet, thereby better meeting different usage requirements.

[0006] As a further improvement of the above technical solution, the heat exchanger includes a heat exchange shell, a pure water heat exchange tube, a cold water heat exchange tube and a boiling water heat exchange tube. The pure water heat exchange tube, the cold water heat exchange tube and the boiling water heat exchange tube are respectively in contact with each other and arranged in the heat exchange shell. Both ends of the pure water heat exchange tube, the two ends of the cold water heat exchange tube, and the two ends of the boiling water heat exchange tube extend out of the heat exchange shell respectively. The pure water heat exchange zone is formed in the pure water heat exchange tube, the cold water heat exchange zone is formed in the cold water heat exchange tube, the boiling water heat exchange zone is formed in the boiling water heat exchange tube, and the concentrated water heat exchange zone is formed in the heat exchange shell. Pure water heat exchange tubes for conveying pure water, cold water heat exchange tubes for conveying cold water, and boiling water heat exchange tubes for conveying boiling water are arranged in the heat exchange shell, while concentrated water flows directly in the heat exchange shell. The pure water heat exchange tubes and the cold water heat exchange tubes exchange heat by contact with the boiling water heat exchange tubes, thereby transferring the heat of the boiling water to the pure water, cold water and concentrated water. Since the concentrated water is conveyed by utilizing the space inside the heat exchange shell, the blockage of the concentrated water heat exchange area can be effectively reduced, thereby ensuring stable heat exchange in the heat exchanger.

[0007] As a further improvement of the above technical solution, the pure water heat exchange tube, the cold water heat exchange tube and the boiling water heat exchange tube are respectively extended back and forth in a serpentine shape along the length direction of the heat exchange shell. The serpentine design of the pure water heat exchange tube, the cold water heat exchange tube and the boiling water heat exchange tube extends the water flow path, thereby improving the heat exchange efficiency of pure water, cold water, boiling water and concentrated water in the heat exchanger and improving the heat utilization rate.

[0008] As a further improvement of the above technical solution, a plurality of limiting ribs are connected at intervals along the length direction of the heat exchange shell, and the pure water heat exchange tube, the cold water heat exchange tube and the boiling water heat exchange tube all bypass the plurality of limiting ribs. The plurality of limiting ribs can form multiple flow barriers along the length direction of the space inside the heat exchange shell, which can reduce the flow rate of concentrated water, extend the flow path of concentrated water in the heat exchange shell, and improve the heat exchange efficiency between concentrated water and boiling water. In addition, the plurality of limiting ribs can limit the pure water heat exchange tube, the cold water heat exchange tube and the boiling water heat exchange tube, and improve the installation stability of the pure water heat exchange tube, the cold water heat exchange tube and the boiling water heat exchange tube in the heat exchange shell.

[0009] As a further improvement of the above technical solution, the heat exchanger includes a heat exchange main pipe, and four mutually separated flow channels are formed in the heat exchange main pipe, and the four flow channels are respectively the pure water heat exchange area, the concentrated water heat exchange area, the cold water heat exchange area and the boiling water heat exchange area. Four mutually separated flow channels are directly formed in a heat exchange main pipe, and pure water, concentrated water, cold water and boiling water directly flow and exchange heat in the heat exchange main pipe, and the overall structure is simple.

[0010] As a further improvement of the above technical solution, the heat exchange main pipe extends back and forth in a serpentine shape. The heat exchange main pipe extends in a serpentine shape, which prolongs the flow path of pure water, concentrated water, cold water and boiling water during heat exchange, thereby improving the heat exchange efficiency.

[0011] A second aspect of the present invention provides a temperature adjustment method, using the above-mentioned purified drinking water temperature adjustment system, comprising: Obtain the required pure water temperature, pure water flow rate and inlet water temperature; Calculate a first temperature difference according to the pure water temperature and the inlet water temperature; The water inlet flow rate is controlled and adjusted according to the first temperature difference and the pure water flow rate.

[0012] This technical solution has at least the following beneficial effects: according to the required pure water temperature and the inlet water temperature such as the water temperature required for heat exchange with the pure water, the first temperature difference between the two is determined; at this time, according to the pure water flow rate required for the pure water output, the required mixing ratio for heat exchange between the pure water and the inlet water is determined, thereby controlling and adjusting the inlet water flow rate to achieve the regulation of the pure water temperature, so that the temperature of the pure water to be output can be adjusted, and in the temperature adjustment process, the utilization rate of thermal energy is improved by the continuous circulation and conversion between pure water, boiling water, boiled water and cold water, thereby reducing working energy consumption, enriching the overall use function, and improving overall practicality.

[0013] As a further improvement of the above technical solution, the water inlet temperature includes the cold water temperature in the ice liner and / or the boiling water temperature in the heater. According to the required output pure water temperature, it is determined whether cold water or boiling water needs to be added for heat exchange, or whether cold water and boiling water need to be added at the same time. At this time, the cold water temperature in the ice liner and the boiling water temperature in the heater need to be obtained accordingly to obtain the first temperature difference with the pure water.

[0014] A third aspect of the present invention provides a temperature adjustment method, using the above-mentioned purified drinking water temperature adjustment system, comprising: Obtaining the required mixed water temperature, mixed water flow rate, boiling water temperature in the heater and outlet water temperature of the boiling water heat exchange zone; A second temperature difference is calculated based on the mixed water temperature and the boiling water temperature in the heater, and a third temperature difference is calculated based on the boiling water temperature in the heater and the outlet water temperature of the boiling water heat exchange zone; The water inlet flow rate of the first mixed water inlet and the water inlet flow rate of the second mixed water inlet are controlled and adjusted according to the second temperature difference, the third temperature difference and the mixed water flow rate.

[0015] This technical solution has at least the following beneficial effects: the second temperature difference is determined according to the required output temperature of boiled water, the required temperature of boiled water mixed from the boiling water heat exchange zone, and the boiling water temperature mixed from the heater. At this time, the required mixing ratio for heat exchange between boiled water and boiling water is determined according to the mixed water flow required for the output of boiled water, so as to control and adjust the water inlet flow to achieve the regulation of the temperature of boiled water. In this way, the temperature of boiled water to be output can be adjusted, and in the process of temperature adjustment, the utilization rate of thermal energy is improved by continuous circulation and conversion between boiled water, boiling water, boiled water and cold water, thereby reducing working energy consumption, enriching the overall use function, and improving overall practicality.

[0023] In this pure drinking water temperature control system, the raw water from the outside enters the water purifier 1 from the raw water inlet, and the raw water is filtered by the water purifier 1 to obtain purified pure water, which is discharged from the pure water outlet to the pure water heat exchange zone of the heat exchanger 2, and the concentrated water containing impurities after purification is discharged from the concentrated water outlet to the concentrated water heat exchange zone of the heat exchanger 2. When normal temperature water is needed, the pure water in the pure water heat exchange zone can be directly discharged; when high-temperature pure water is needed, part of the pure water in the pure water heat exchange zone enters the heater 4 from the third pure water inlet through the pipeline, and is heated by the heater 4 and refluxed to the boiling water heat exchange zone. The boiling water in the boiling water heat exchange zone exchanges heat with the pure water in the pure water heat exchange zone and the concentrated water in the concentrated water heat exchange zone, so that the pure water is heated and heated before being output, and the boiled hot water is cooled to boiled water after heat exchange, and enters the ice tank 3 from the second pure water inlet for storage; when the temperature of the pure water heating needs to be lowered, the water in the ice tank 3 can also be heated. The boiled water is input from the first cold water outlet to the cold water heat exchange zone, neutralizing the temperature in the boiling water heat exchange zone, thereby reducing the temperature of the pure water output from the pure water heat exchange zone; when cold water needs to be output, low-temperature boiled water can be obtained directly from the second cold water outlet; when the boiled water in the ice tank 3 needs to be reheated, the boiled water in the ice tank 3 can be input into the cold water heat exchange zone, and the temperature is increased after heat exchange with the boiling water heat exchange zone to obtain the reheated boiled water. In this process, pure water is also continuously fed from the pure water heat exchange zone into the heater 4 for heating, and the boiled water obtained after heat exchange in the boiling water heat exchange zone is replenished into the ice tank 3, realizing dynamic circulation and replenishment, so that the pure water and boiled water to be output can be temperature-controlled, and in the temperature control process, the utilization rate of thermal energy is improved by continuous circulation and conversion between pure water, boiling water, boiled water and cold water, thereby reducing working energy consumption, enriching the overall use function and improving the overall practicality.

[0024] The present invention also includes a water mixing and temperature regulating valve 5, which has a first water mixing inlet, a second water mixing inlet and a water mixing outlet, wherein the first water mixing inlet is connected to the boiling water outlet through a pipeline, and the second water mixing inlet is connected to the boiling water heat exchange zone through a pipeline. When in use, the outputted boiled water can also be temperature-regulated. Specifically, boiled water cooled in the boiling water heat exchange zone is inputted into the water mixing and temperature regulating valve 5 from the second water mixing inlet, and boiling water heated by the heater 4 is outputted into the water mixing and temperature regulating valve from the first water mixing inlet, thereby heating boiled water again. The water flow rate entering from the first water mixing inlet and the second water mixing inlet is controlled by the water mixing and temperature regulating valve 5 itself, thereby realizing outputting boiled water heated again from the water mixing outlet, thereby better meeting different usage requirements.

[0025] The heat exchanger 2 needs to provide multiple independent partitions inside to allow different water to flow and exchange heat. There are many structural forms, such as Figure 3As shown, in embodiment 1, the heat exchanger 2 includes a heat exchange shell 21, a pure water heat exchange tube 22, a cold water heat exchange tube 23 and a boiling water heat exchange tube 24, the pure water heat exchange tube 22, the cold water heat exchange tube 23 and the boiling water heat exchange tube 24 are respectively in contact with each other and arranged in the heat exchange shell 21, both ends of the pure water heat exchange tube 22, both ends of the cold water heat exchange tube 23, and both ends of the boiling water heat exchange tube 24 extend out of the heat exchange shell 21 respectively, the pure water heat exchange zone is formed in the pure water heat exchange tube 22, the cold water heat exchange zone is formed in the cold water heat exchange tube 23, the boiling water heat exchange zone is formed in the boiling water heat exchange tube 24, and the concentrated water heat exchange zone is formed in the heat exchange shell 21. A pure water heat exchange tube 22 for conveying pure water, a cold water heat exchange tube 23 for conveying cold water, and a boiling water heat exchange tube 24 for conveying boiling water are respectively arranged in the heat exchange shell 21, and the concentrated water flows directly in the heat exchange shell 21. The pure water heat exchange tube 22 and the cold water heat exchange tube 23 exchange heat with the boiling water heat exchange tube 24 through contact, thereby transferring the heat of the boiling water to the pure water, cold water and concentrated water. Since the concentrated water is conveyed by utilizing the space inside the heat exchange shell 21, the blockage of the concentrated water heat exchange area can be effectively reduced, thereby ensuring stable heat exchange in the heat exchanger 2.

[0026] Furthermore, the pure water heat exchange tube 22, the cold water heat exchange tube 23 and the boiling water heat exchange tube 24 extend back and forth in a serpentine shape along the length direction of the heat exchange shell 21. The serpentine design of the pure water heat exchange tube 22, the cold water heat exchange tube 23 and the boiling water heat exchange tube 24 extends the water flow path, thereby improving the heat exchange efficiency of pure water, cold water, boiling water and concentrated water in the heat exchanger 2 and improving the heat utilization rate.

[0027] Furthermore, a plurality of limiting ribs 211 are connected at intervals along the length direction of the heat exchange shell 21, and the pure water heat exchange tube 22, the cold water heat exchange tube 23, and the boiling water heat exchange tube 24 all bypass the plurality of limiting ribs 211. The plurality of limiting ribs 211 can form multiple flow barriers along the length direction of the space inside the heat exchange shell 21, which can reduce the flow rate of concentrated water, extend the flow path of concentrated water in the heat exchange shell 21, and improve the heat exchange efficiency between concentrated water and boiling water. In addition, the plurality of limiting ribs 211 can limit the pure water heat exchange tube 22, the cold water heat exchange tube 23, and the boiling water heat exchange tube 24, and improve the installation stability of the pure water heat exchange tube 22, the cold water heat exchange tube 23, and the boiling water heat exchange tube 24 in the heat exchange shell 21.

[0028] In the second embodiment, the heat exchanger 2 includes a heat exchange main pipe, and four mutually separated flow channels are formed in the heat exchange main pipe, and the four flow channels are respectively the pure water heat exchange area, the concentrated water heat exchange area, the cold water heat exchange area and the boiling water heat exchange area. Four mutually separated flow channels are directly formed in a heat exchange main pipe, and pure water, concentrated water, cold water and boiling water directly flow and exchange heat in the heat exchange main pipe, and the overall structure is simple.

[0029] Furthermore, the heat exchange main pipe extends back and forth in a serpentine shape, which prolongs the flow path of pure water, concentrated water, cold water and boiling water during heat exchange, thereby improving the heat exchange efficiency.

[0030] A second aspect of the present invention provides a temperature adjustment method, which uses the above-mentioned purified drinking water temperature adjustment system, including but not limited to the following steps: Step S110, obtaining the required pure water temperature, pure water flow rate and inlet water temperature; Step S120, calculating a first temperature difference according to the pure water temperature and the inlet water temperature; Step S130, controlling and adjusting the water inlet flow rate according to the first temperature difference and the pure water flow rate.

[0031] This temperature control method is mainly used to adjust the temperature of pure water outlet. According to the required pure water temperature and the inlet water temperature required for heat exchange with the pure water, the first temperature difference between the two is determined. At this time, according to the pure water flow required for pure water output, the required mixing ratio for heat exchange between pure water and inlet water is determined, so as to control and adjust the inlet water flow to achieve the regulation of pure water temperature. In this way, the pure water to be output can be temperature-controlled, and in the temperature control process, the utilization rate of thermal energy is improved by continuous circulation and conversion between pure water, boiling water, boiled water and cold water, thereby reducing working energy consumption, enriching the overall use function and improving overall practicality.

[0032] In step S110, the water inlet temperature includes the cold water temperature in the ice liner 3 and / or the boiling water temperature in the heater 4. Therefore, in step S10, obtaining the water inlet temperature includes obtaining the cold water temperature in the ice liner 3 and / or the boiling water temperature in the heater 4. According to the required output pure water temperature, it is determined whether cold water or boiling water needs to be added for heat exchange, or whether cold water and boiling water need to be added at the same time. At this time, the cold water temperature in the ice liner 3 and the boiling water temperature in the heater 4 need to be obtained accordingly to obtain the first temperature difference with the pure water.

[0033] A third aspect of the present invention provides a temperature adjustment method, which uses the above-mentioned purified drinking water temperature adjustment system, including but not limited to the following steps: Step S210, obtaining the required mixed water temperature, mixed water flow rate, boiling water temperature in the heater 4 and outlet water temperature of the boiling water heat exchange zone; Step S220, calculating a second temperature difference value according to the mixed water temperature and the boiling water temperature in the heater 4, and calculating a third temperature difference value according to the boiling water temperature in the heater 4 and the outlet water temperature of the boiling water heat exchange zone; Step S230: controlling and adjusting the water inlet flow rate of the first mixed water inlet and the water inlet flow rate of the second mixed water inlet according to the second temperature difference, the third temperature difference and the mixed water flow rate.

[0034] This temperature control method is mainly used to adjust the temperature of the mixed boiled water output. The second temperature difference is determined according to the required boiled water temperature to be output, the required boiled water temperature to be mixed from the boiling water heat exchange zone, and the boiling water temperature to be mixed from the heater 4. At this time, the required mixing ratio of boiled water and boiling water for heat exchange is determined according to the mixed water flow required for the boiled water output, so as to control and adjust the water inlet flow to achieve the regulation of the boiled water temperature. In this way, the boiled water to be output can be temperature-controlled, and in the process of temperature control, the utilization rate of thermal energy is improved by continuous circulation and conversion among boiled water, boiling water, boiled water and cold water, thereby reducing working energy consumption, enriching the overall use function and improving the overall practicality.
