AI Technical Summary
In the water system of the milk brewer, the milk powder in the mixing chamber cannot be completely mixed with water when soaking milk at a small flow rate, resulting in accumulation of powder blocks and hygiene problems.
By setting the first three-way valve and the second three-way valve in the waterway system of the milk brewer, the water circulation between the boiler and the constant temperature chamber is realized. When it is necessary to use the water in the constant temperature chamber, it is directly introduced into the mixing chamber to prevent the water from passing through the boiler and other devices and reduce water pressure loss.
When brewing milk powder in small flow, the milk powder in the mixing chamber can be mixed evenly, reducing the accumulation of powder blocks, improving the hygiene of the mixing chamber, and reducing the cost and complexity of the waterway system.

Description
Technical Field
[0001] The utility model relates to the technical field of milk powder dispensers, and particularly relates to a water circuit system of a milk powder dispenser. Background Art
[0002] The milk powder dispenser generates hot water through a water circuit system to inject the hot water into a mixing bin to brew milk powder. As Figure 1 shown, in the related art, the water circuit system of the milk powder dispenser includes a water tank, a heat exchange and cooling module, a boiler, and a constant temperature bin. Water is pumped from the water tank by a water pump ①, passes through the heat exchange and cooling module and then enters the boiler to be heated and boiled. After that, it passes through the A outlet of a three-way solenoid valve ①, reaches the B outlet of a solenoid valve ② and then returns to the heat exchange. After being cooled by the heat exchange and cooling module, it enters the constant temperature bin through a three-way joint. When the water in the constant temperature bin reaches the set flow rate, a water pump ② starts to pump water, passes through the boiler, then reaches the B outlet of the three-way solenoid valve ①, and then reaches the constant temperature bin, and circulates in this way for heat preservation. After the water in the constant temperature bin is circulated and kept at a specified temperature, when water is needed, at this time, the solenoid valve ① switches to the A outlet, and the solenoid valve ② switches to the A outlet, and the water at the required temperature flows to the mixing bin for milk powder brewing.
[0003] In the above water circuit system, when the water in the constant temperature bin is needed for milk powder brewing, the water pump pumps the water in the constant temperature bin out. The water needs to pass through the boiler and two solenoid valves before it can enter the mixing bin for milk powder brewing. The resistance of the pipeline system is large, and there is more water pressure loss. When the milk powder dispenser brews milk with a small flow rate such as 20 - 30 ml, and the mixing ratio of milk powder to water is greater than 3 times or more, the milk powder in the mixing bin cannot be completely stirred and mixed evenly by the water, resulting in the accumulation of powder blocks on the inner surface of the mixing bin, uneven stirring of dry powder, etc., and there is residual milk powder on the inner surface of the mixing bin, which affects the hygiene of the mixing bin.

[0016] 1. In the present utility model, the waterway system pumps the water in the water tank into the boiler through the first water pump. After being heated by the boiler, the water can directly enter the mixing bin to make milk powder, or can be stored in the constant temperature bin and taken for use after the temperature reaches the required temperature stably. Specifically, when not making milk powder, the A water outlet interface of the first three-way valve is closed, and the B water outlet interface is opened. The water in the constant temperature bin can be driven by the second water pump and connected to the water inlet interface of the boiler through the B water outlet interface of the first three-way valve, so that the water circulates between the boiler and the constant temperature bin to keep the temperature constant; when the water in the constant temperature bin needs to be taken for use, the A water outlet interface is opened, and the B water outlet interface is closed. The water in the constant temperature bin can directly enter the mixing bin through the A water outlet interface to make milk powder. Thus, the water does not need to pass through the boiler and other devices, reducing the water flow path, and further reducing the water pressure loss, so that the milk powder in the mixing bin can be evenly mixed when making milk powder in a small flow rate, and it is not easy for powder blocks to accumulate on the inner surface of the mixing bin, ensuring the hygiene condition in the mixing bin.
[0017] 2. By connecting the mixing bin, the boiler and the A water outlet interface of the first three-way valve through the first three-way joint, the waterway between the A water outlet interface and the mixing bin shares a part of the pipeline with the waterway between the boiler and the mixing bin, which can reduce the cost of the pipeline and at the same time reduce the pipe fittings joints arranged on the mixing bin, facilitating the installation of the waterway system.
[0018] 3. By setting the second three-way valve and the third three-way valve, the water discharged from the boiler can directly enter the constant temperature bin through the D water outlet interface, or can enter the mixing bin through the C water outlet interface and the E water outlet interface to directly make milk powder.
[0019] 4. The water flowing out of the water tank enters through the cold water inlet of the heat exchanger and flows out from the cold water outlet of the heat exchanger. The water heated by the boiler can enter the hot water inlet of the heat exchanger through the C water outlet interface and the F water outlet interface and flow out from the hot water outlet of the heat exchanger. Thus, the water in the water tank is preliminarily heated by the heat exchanger, which can reduce the power required by the boiler, achieving the effect of energy saving. At the same time, the water heated by the boiler can be cooled down to reach the required temperature for drinking. Description of the Drawings

Specific embodiments
[0024] The present invention will be further described below with reference to the accompanying drawings.
[0025] This embodiment discloses a water circuit system 1000 of a milk powder mixer. Referring to Figure 2 , the water circuit system includes a water tank 100, a first water pump 200, a boiler 300, a constant temperature bin 400, and a mixing bin 500. The water tank 100 is used to store unheated water. The water tank 100 is connected to the water inlet of the boiler 300. The first water pump 200 is arranged between the boiler 300 and the water tank 100. The first water pump 200 pumps the water in the water tank 100 into the water inlet of the boiler 300. The water outlet of the boiler 300 is respectively connected to the constant temperature bin 400 and the mixing bin 500, so that the water heated by the boiler 300 can enter the mixing bin 500 to mix milk powder or enter the constant temperature bin 400 for storage.
[0026] A heat exchanger 600 is arranged between the water tank 100 and the boiler 300. The heat exchanger 600 has a cold water inlet 610, a cold water outlet 620, a hot water inlet 630, and a hot water outlet 640. The water tank 100 is connected to the water inlet of the first water pump 200. The water outlet of the first water pump 200 is connected to the cold water inlet 610 of the heat exchanger 600. The cold water outlet 620 of the heat exchanger 600 is connected to the water inlet of the boiler 300. The water heated by the boiler 300 can flow through the heat exchanger 600 through the hot water inlet 630 of the heat exchanger 600 and flow out from the hot water outlet 640. Thus, the cold water flowing out of the water tank 100 is preliminarily heated by the heat exchanger 600, the power requirement of the heat exchanger 600 is reduced, the energy consumption is reduced, and at the same time, the hot water flowing out of the boiler 300 can also be cooled down to a suitable temperature for drinking.
[0027] At the water outlet of the boiler 300, a second three-way valve 102 and a third three-way valve 103 are provided. The second three-way valve 102 has a C water outlet interface and a D water outlet interface, and the third three-way valve 103 has an E water outlet interface and an F water outlet interface. The water inlet interface of the second three-way valve 102 is connected to the water outlet of the boiler 300, the D water outlet interface is connected to the constant temperature chamber 400, and the C water outlet interface is connected to the water inlet interface of the third three-way valve 103. The E water outlet interface is connected to the mixing chamber 500.
[0028] Thus, the hot water at the water outlet of the boiler 300 can enter the constant temperature chamber 400 through the D water outlet interface of the second three-way valve 102 for storage, or can enter the mixing chamber 500 through the C water outlet interface of the second three-way valve 102 and the E water outlet interface of the third three-way valve 103 to brew milk powder.
[0029] Among them, the F water outlet interface of the third three-way valve 103 is connected to the hot water inlet 630 of the heat exchanger 600, and the hot water outlet 640 of the heat exchanger 600 is connected to the constant temperature chamber 400. Thus, when the C water outlet interface of the second three-way valve 102 is opened, the D water outlet interface is closed, and the E water outlet interface of the third three-way valve 103 is closed and the F water outlet interface is opened, the hot water flowing out of the water outlet of the boiler 300 can enter the hot water inlet 630 of the heat exchanger 600 for heat exchange, and then flow out from the hot water outlet 640 of the heat exchanger 600 to the constant temperature chamber 400, realizing the preliminary heating of the water flowing out of the water tank 100 and the cooling of the hot water.
[0030] In this embodiment, a second three-way joint 202 is connected between the D water outlet interface of the second three-way valve 102 and the constant temperature chamber 400. The three interfaces of the second three-way joint 202 are respectively connected to the D water outlet interface, the hot water outlet 640 of the heat exchanger 600, and the constant temperature chamber 400. Thus, a section of pipeline is shared between the water path flowing out of the heat exchanger 600 to the constant temperature chamber 400 and the water path flowing out of the D water outlet interface to the constant temperature chamber 400 between the second three-way joint 202 and the constant temperature chamber 400, reducing pipeline consumables and saving costs. In addition, in other embodiments, the second three-way joint 202 may not be provided, and the D water outlet interface and the hot water outlet 640 of the heat exchanger 600 are respectively connected to the constant temperature chamber 400 through independent pipelines.
[0031] In this embodiment, a second water pump 700 and a first three-way valve 101 are connected between the constant temperature chamber 400 and the water inlet of the boiler 300. The water inlet of the second water pump 700 is connected to the constant temperature chamber 400, and the water outlet of the second water pump 700 is connected to the water inlet interface of the first three-way valve 101. The first three-way valve 101 has an A water outlet interface and a B water outlet interface. The A water outlet interface is connected to the mixing chamber 500, and the B water outlet interface is connected to the water inlet of the boiler 300.
[0032] When water needs to be heated, the first water pump 200 and the boiler 300 are started, and the A water outlet interface and the B water outlet interface of the first three-way valve 101 are closed. The water in the water tank 100 flows through the heat exchanger 600 and then enters the boiler 300 for heating.
[0033] When direct milk powder brewing is needed, the C water outlet interface of the second three-way valve 102 is opened and the D water outlet interface is closed, and the E water outlet interface of the third three-way valve 103 is opened and the F water outlet interface is closed. The water heated by the boiler 300 directly enters the mixing chamber 500 through the C water outlet interface and the E water outlet interface.
[0034] When the constant temperature chamber 400 needs to store water, the C water outlet interface of the second three-way valve 102 is closed and the D water outlet interface is opened, and the water heated by the boiler 300 directly enters the constant temperature chamber 400. Or, the C water outlet interface of the second three-way valve 102 is opened and the D water outlet interface is closed, the E water outlet interface of the third three-way valve 103 is closed and the F water outlet interface is opened, and the water heated by the boiler 300 enters the heat exchanger 600 through the C water outlet interface and the F water outlet interface, and after heat exchange and temperature reduction, it flows into the constant temperature chamber 400 through the second three-way joint 202.
[0035] When the set flow rate is reached in the constant temperature chamber 400, the second water pump 700 is started, the A water outlet interface of the first three-way valve 101 is closed and the B water outlet interface is opened, and the C water outlet interface of the second three-way valve 102 is closed and the D water outlet interface is opened. The water in the constant temperature chamber 400 returns to the constant temperature chamber 400 after passing through the second water pump 700, the boiler 300 and the D water outlet interface, and circulates in this way until the water temperature in the constant temperature chamber 400 is constant.
[0036] When the water in the constant temperature chamber 400 needs to be used, the A water outlet interface of the first three-way valve 101 is opened, the B water outlet interface is closed, and the second water pump 700 is started to discharge the water in the constant temperature chamber 400 to the mixing chamber 500 through the A water outlet interface. Thus, the water does not need to pass through the boiler 300 and other devices, reducing the water flow path, thereby reducing the water pressure loss, enabling the milk powder in the mixing chamber 500 to be evenly mixed during small-flow milk powder brewing, preventing powder blocks from accumulating on the inner surface of the mixing chamber 500, and ensuring the hygiene in the mixing chamber 500.
[0037] In this embodiment, the mixing chamber 500 is connected to a first three-way joint 201. The three joints of the first three-way joint 201 are respectively connected to the mixing chamber 500, the water outlet of the boiler 300, and the A water outlet interface of the first three-way valve 101. This enables the water path between the A water outlet interface and the mixing chamber 500 to share a part of the pipeline with the water path between the boiler 300 and the mixing chamber 500, which can reduce the cost of the pipeline and at the same time reduce the pipe fittings joints provided on the mixing chamber 500, facilitating the installation of this water path system. In addition, in other embodiments, the first three-way joint 201 may not be provided, and the A water outlet interface and the boiler 300 are connected to the mixing chamber 500 through independent pipelines.
[0038] The "connection" in this embodiment can be either a direct connection between two mechanisms or an indirect connection between two mechanisms through other mechanisms.
[0039] In this embodiment, the first three-way joint 201 is provided between the E water outlet interface of the third solenoid valve and the mixing chamber 500, that is, the three joints of the first three-way joint 201 are respectively connected to the mixing chamber 500, the A water outlet interface, and the E water outlet interface.
[0040] In addition, in some embodiments, the first three-way joint 201 may also be provided between the water outlet of the boiler 300 and the second three-way valve 102. The three joints of the first three-way joint 201 are respectively connected to the water outlet of the boiler 300, the water inlet interface of the second three-way valve 102, and the A water outlet interface.
[0041] In some embodiments, the first three-way joint 201 may also be provided between the second three-way valve 102 and the third three-way valve 103. The three joints of the first three-way joint 201 are respectively connected to the C water outlet interface, the water inlet interface of the third three-way valve 103, and the A water outlet interface.
[0042] The above are only the preferred embodiments of the present invention.
