Part of the water flows through the third water flow channel directly into the heating element for heating, and part of the water flows through the fourth water flow channel from the cooling water inlet into the heat exchange structure to cool the hot water.

The cooling water enters the cooling water channel through the cooling water inlet of the heat exchange structure.

Then, it flows into the heat exchange inlet through the hot water outlet and flows out from the first water outlet along the second channel for user use. The flow rate of cooling water can be controlled by adjusting the ratio of the flow rate of water entering the third water flow channel and the fourth water flow channel to achieve the goal of taking boiled water at different temperature levels. The energy absorbed by the cooling water is not wasted. The temperature of the cooling water increases after heat exchange and flows to the heating element for heating, and this part of the heat can be recycled. When the boiled water level at a lower temperature is read, the water in the clean water tank flows into the second water flow channel through the first end of the second water flow channel, and all the water flows into the fourth water flow channel. The water flows through my solution number.

[0038] The fourth water flow channel enters the heat exchange structure from the cooling water inlet to cool the hot water. The cooling water after heat exchange and heating flows into the fifth water flow channel through the cooling water outlet, enters the heating element and is heated to a boiling water state. The boiled water flows into the first water inlet, and then flows from the heat exchange outlet along the first channel to the hot water channel of the heat exchange structure. After heat exchange with the cooling water in the heat exchange structure, the boiled water is cooled into boiled water. Since the flow rate of cooling water entering the heat exchange structure is large, the temperature of the boiled water drops relatively low, and then flows into the heat exchange inlet through the hot water outlet, and flows out from the first water outlet along the second channel for user use.

[0065] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0066] Example 1

[0067] As people's living standards gradually improve, the health of drinking water is receiving increasing attention. As an emerging category of water purifiers, tabletop water purifiers, featuring features like installation-free operation and instant hot water delivery, are gaining widespread popularity. Currently, packaged boiled water is also emerging on the market and is proving popular with consumers.

[0068] Bottled boiled water currently on the market is prepared on an assembly line and then bottled for sale, making it less fresh. Boiling water in a kettle and then cooling it to the desired temperature takes time and isn't instantaneous. A small number of water purifiers or dispensers with boiled water functions are available on the market, but these machines suffer from large overall size, low integration, complex water piping, and complex assembly, resulting in low efficiency.

[0069] For this reason, Figures 1 to 18 As shown, this embodiment provides a water channel assembly.

[0070] In one embodiment, the water channel assembly includes a first water channel plate 1 , a heating element 3 , a heat exchange structure 4 , and a second water channel plate 20 .

[0071] Among them, the first water channel plate 1 is formed with a first water inlet 102, a first water outlet 104, a heat exchange outlet 105, a heat exchange inlet 106, a first channel 108 connecting the first water inlet 102 and the heat exchange outlet 105, and a second channel 109 connecting the heat exchange inlet 106 and the first water outlet 104; the heating element 3 has a heating water inlet 301 and a heating water outlet 302; the heat exchange structure 4 has a cooling water inlet 401, a cooling water outlet 402, a hot water inlet 403, a hot water outlet 404, a cooling water channel connecting the cooling water inlet 401 and the cooling water outlet 402, and a hot water channel connecting the hot water inlet 403 and the hot water outlet 404, the hot water inlet 403 is connected to the heat exchange outlet 105, and the hot water outlet 404 is connected to the heat exchange inlet 106; the second water channel 2006 and the second water channel 2007 are formed on the second water channel plate 20 , the third water flow channel 2008, the fourth water flow channel 2009 and the fifth water flow channel 2010, the first end of the first water flow channel 2006 is suitable for being connected to the clean water outlet of the filter element, the second end of the first water flow channel 2006 is suitable for being connected to the clean water tank, the first end of the second water flow channel 2007 is suitable for being connected to the clean water tank, the first end of the third water flow channel 2008 is suitable for being connected to the second end of the second water flow channel 2007, the second end of the third water flow channel 2008 is connected to the heating water inlet 301, the first end of the fourth water flow channel 2009 is suitable for being connected to the second end of the second water flow channel 2007, the second end of the fourth water flow channel 2009 is connected to the cooling water inlet 401, the first end of the fifth water flow channel 2010 is connected to the cooling water outlet 402, and the second end of the fifth water flow channel 2010 is connected to the heating water inlet 301.

[0072] In this embodiment, when the whole machine is taking out clean water, Figure 15 As shown, the purified water produced by the water system enters the first water flow channel 2006 from the first end of the first water flow channel 2006 of the second waterway plate 20, and then flows out through the second end of the first water flow channel 2006 into the purified water tank. Figure 18As shown, the water in the clean water tank flows into the second water flow channel 2007 through the first end of the second water flow channel 2007, and the water flows in the third water flow channel 2008 and the fourth water flow channel 2009 in a certain proportion. A part of the water flows through the third water flow channel 2008 and directly enters the heating element 3 for heating, and a part of the water flows through the fourth water flow channel 2009 and enters the heat exchange structure 4 from the cooling water inlet 401 to cool the hot water. The cooling water after heat exchange and temperature increase flows into the fifth water flow channel 2010 through the cooling water outlet 402, and cools the third water flow channel 2010. The water in the water flow channel 2008 is merged and enters the heating element 3 to be heated to the boiling water state. The boiling water flows into the first water inlet 102, and then flows along the first channel 108 from the heat exchange outlet 105 to the hot water channel of the heat exchange structure 4. The cooling water enters the cooling water channel through the cooling water inlet 401 of the heat exchange structure 4. The cooling water cools the boiling water in the hot water channel and cools the boiling water into boiled water or warm water. Then, it flows into the heat exchange inlet 106 through the hot water outlet 404, and flows out from the first water outlet 104 along the second channel 109 for user use. The flow rate of cooling water can be controlled by adjusting the ratio of the water flow entering the third water flow channel 2008 and the fourth water flow channel 2009, so as to achieve boiled water of different temperature levels. The energy absorbed by the cooling water is not wasted. The temperature of the cooling water increases after the heat exchange, and flows to the heating element 3 for heating, and this part of the heat can be recycled. When reading the boiled water level with a lower temperature, such as Figure 17 As shown, the water in the clean water tank flows into the second water flow channel 2007 through the first end of the second water flow channel 2007, and all the water flows into the fourth water flow channel 2009. The water flows through the fourth water flow channel 2009 and enters the heat exchange structure 4 from the cooling water inlet 401 to cool the hot water. The cooling water after heat exchange and temperature increase flows into the fifth water flow channel 2010 through the cooling water outlet 402, enters the heating element 3 and is heated to a boiling water state. The boiling water flows to the first water inlet 102, and then my scheme number

[0073] The boiled water flows from the heat exchange outlet 105 along the first channel 108 to the hot water channel of the heat exchange structure 4. After heat exchange with the cooling water in the heat exchange structure 4, the boiled water is cooled into boiled water. Since the flow rate of the cooling water entering the heat exchange structure 4 is large, the temperature of the boiled water drops relatively low. Then, the boiled water flows into the heat exchange inlet 106 through the hot water outlet 404, and flows out from the first water outlet 104 along the second channel 109 for user use.

[0074] By integrating the first channel 108 and the second channel 109 on the first waterway plate 1, complex water pipe connections are avoided, the integration is high, and it is convenient to connect with the solenoid valve 2 and the heat exchange structure 4. By forming the first water flow channel 2006, the second water flow channel 2007, the third water flow channel 2008, the fourth water flow channel 2009 and the fifth water flow channel 2010 on the second waterway plate 20, the integration of the second waterway plate 20 is high, complex water pipe connections are avoided, and it is convenient to connect with the water pump 21, which can greatly reduce the volume of the entire machine.

[0075] On the basis of the above embodiment, in a preferred embodiment, the first waterway plate 1 is further formed with a second water inlet 101, a second water outlet 103, and a third channel 107 connecting the second water inlet 101 and the second water outlet 103. The waterway assembly further comprises a solenoid valve 2 having a water inlet end 201. The solenoid valve 2 has a first state in which the water inlet end 201 is connected to the second water inlet 101 and a second state in which the water inlet end 201 is connected to the first water inlet 102. The heating water outlet 302 is connected to the water inlet end 201. In this embodiment, when the water level is turned on, as shown in FIG. Figure 16 As shown, the water in the clean water tank flows into the second water flow channel 2007 through the first end of the second water flow channel 2007, and then flows into the third water flow channel 2008. There is no flow in the fourth water flow channel 2009. Then the water flows into the heating element 3 and is heated to the boiling water state. The boiling water flows from the heating water outlet 302 to the second water inlet 101, and then flows out from the second water outlet 103 along the third channel 107 for user use. When the normal temperature boiled water gear is read, the solenoid valve 2 is switched to In the second state, boiling water flows from the solenoid valve 2 to the first water inlet 102, and then flows along the first channel 108 from the heat exchange outlet 105 to the hot water channel of the heat exchange structure 4. The cooling water enters the cooling water channel through the cooling water inlet 401 of the heat exchange structure 4. The cooling water cools the boiling water in the hot water channel, cooling the boiling water into boiled water or warm water, and then flows into the heat exchange inlet 106 through the hot water outlet 404, and flows out from the first water outlet 104 along the second channel 109 for user use.

[0076] My plan number

[0077] Based on the above embodiment, in a preferred embodiment, the water channel assembly further includes a water pump 21 and / or a regulating valve 22. The water pump 21 is connected between the second end of the second water flow channel 2007 and the first end of the third water flow channel 2008; the regulating valve 22 is provided on the third water flow channel 2008 and can adjust the ratio of the water flow entering the third water flow channel 2008 to the water flow entering the fourth water flow channel 2009.

[0078] When taking the boiling water gear, Figure 16As shown, start the water pump 21, and the water pump 21 allows the water in the clean water tank to flow into the second water flow channel 2007 through the first end of the second water flow channel 2007. After passing through the water pump 21, the regulating valve 22 is in a fully open state. Due to the water pressure, the water flows into the third water flow channel 2008, and there is no flow in the fourth water flow channel 2009. Then the water flows into the heating element 3 and is heated to a boiling water state. The boiling water flows from the heating water outlet 302 into the water inlet end 201 of the solenoid valve 2, switching the solenoid valve 2 to the first state. The boiling water flows from the solenoid valve 2 to the second water inlet 101, and then flows out from the second water outlet 103 along the third channel 107 for user use. When reading the normal temperature boiled water gear, as shown in FIG. Figure 18 As shown, the water pump 21 is started, and the water pump 21 allows the water in the clean water tank to flow into the second water flow channel 2007 through the first end of the second water flow channel 2007. After passing through the water pump 21, the regulating valve 22 is in a non-fully open state. By adjusting the opening of the regulating valve 22, the water flows in the third water flow channel 2008 and the fourth water flow channel 2009 in a certain proportion. A part of the water flows through the third water flow channel 2008 directly into the heating element 3 for heating, and a part of the water flows through the fourth water flow channel 2009 from the cooling water inlet 401 into the heat exchange structure 4 to cool the hot water. The cooling water after heat exchange and heating flows into the cooling water outlet 402. The water in the fifth water flow channel 2010 merges with the water in the third water flow channel 2008 and enters the heating element 3 to be heated to a boiling state. The solenoid valve 2 is then switched to the second state, and the boiling water flows from the solenoid valve 2 to the first water inlet 102. It then flows along the first channel 108 from the heat exchange outlet 105 to the hot water channel of the heat exchange structure 4. Cooling water enters the cooling water channel through the cooling water inlet 401 of the heat exchange structure 4. The cooling water cools the boiling water in the hot water channel, turning it into boiled water or warm water. The cooling water then flows through the hot water outlet 404 into the heat exchange inlet 106 and out of the first water outlet 104 along the second channel 109 for user use. The ratio of the water flow rates entering the third water flow channel 2008 and the fourth water flow channel 2009 can be adjusted by the regulating valve 22 to control the cooling water flow rate, thereby achieving the goal of providing boiled water at different temperature levels. The energy absorbed by the cooling water is not wasted. After heat exchange, the cooling water temperature rises and flows to the heating element 3 for heating, where this heat can be recycled. When reading the lower temperature of boiled water, Figure 17As shown, the regulating valve 22 is adjusted to the closed state, and the water pump 21 allows the water in the clean water tank to flow into the second water flow channel 2007 through the first end of the second water flow channel 2007. After passing through the water pump 21, the water flows into the fourth water flow channel 2009. The water flows through the fourth water flow channel 2009 and enters the heat exchange structure 4 from the cooling water inlet 401 to cool the hot water. The cooling water after heat exchange and temperature increase flows into the fifth water flow channel 2010 through the cooling water outlet 402, enters the heating element 3 and is heated to a boiling water state, and the electric The magnetic valve 2 switches to the second state, and the boiled water flows from the second water outlet end 203 of the solenoid valve 2 to the first water inlet 102, and then flows along the first channel 108 from the heat exchange outlet 105 to the hot water channel of the heat exchange structure 4. After heat exchange with the cooling water in the heat exchange structure 4, the boiled water is cooled into boiled water. Since the flow rate of the cooling water entering the heat exchange structure 4 is large, the temperature of the boiled water drops relatively low, and then flows into the heat exchange inlet 106 through the hot water outlet 404, and flows out from the first water outlet 104 along the second channel 109 for user use.

[0079] It should be noted that when the regulating valve 22 is in a fully open state, the water pressure after the water pump 21 is equal to the water pressure of the heating element interface 2003, so the water flow will not enter the fourth channel.

The forward conduction pressure of the first check valve 26 is greater than the pressure of the water flow from the filter element. Without the first check valve 26, when the entire system is not in operation for water production, a small amount of water from the filter element will continue to flow toward the clean water tank. This small amount of water has the problem of a high TDS value. If it directly enters the clean water tank, it will contaminate the water in the clean water tank. In this embodiment, the first check valve 26 is installed, which requires a certain pressure to conduct forward conduction, thereby preventing the water from flowing into the clean water tank and contaminating the clean water.
