Description

Technical Field

[0001] The utility model relates to the technical field of warm water machines, in particular to a water circuit system of a warm water machine and a warm water machine. Background Art

[0002] With the improvement of people's living standards, warm water machines are widely used in people's lives. Traditional warm water machines mix the water heated to boiling with the cold water that has not been heated, so that the water temperature reaches a suitable temperature for users to drink. However, since the cold water has not been heated, there may be residual bacteria in the drinking water flowing out of such traditional warm water machines, which will affect the health of users.

[0003] In response to this, some warm water machines have emerged on the market. First, the cold water is heated and disinfected, and then a part of the heated water is cooled and mixed with another part of the uncooled hot water to obtain warm water, so as to solve the problem that the drinking water of traditional warm water machines may remain bacteria. However, the energy consumption of quickly cooling hot water is relatively large. In addition, some users may need warm water at a specific temperature. For example, when making milk powder, 40°C warm water is required. However, such warm water machines generally set a mixing valve at the water outlet, and the mixing ratio of cold and hot water is manually adjusted through the mixing valve. It is difficult for users to adjust the water temperature at the water outlet to a suitable temperature, which may cause the temperature at the water outlet to be too high or too low, and it is necessary to frequently try and adjust the mixing ratio of cold and hot water in the mixing valve.

[0012] The utility model has at least the following beneficial effects: The water inlet pipe provides cold water for the water circuit system of the warm water dispenser. The cold water enters the cold water channel of the heat exchanger from the water inlet pipe, and is preheated through the action of the heat exchanger, and then flows into the heating device. The heating device disinfects the cold water at a high temperature to obtain drinkable hot water. The heated hot water is split into a first branch and a second branch. Among them, the hot water in the first branch enters the hot water channel of the heat exchanger for heat exchange, and the temperature decreases to form warm water, which converges with the hot water in the second branch at the water outlet pipe for the user to drink. In the heat exchanger, the cold water in the cold water pipe exchanges heat with the hot water in the hot water pipe. The cold water is preheated before entering the heating device, which can reduce the energy consumption of the heating device. In addition, a first water pump is arranged on the first branch and / or the second branch, which can control the flow rate of the first branch and / or the second branch, so as to adjust the water outlet temperature at the water outlet pipe to a specific temperature, without the user frequently trying and adjusting the water temperature by trial and error, that is, it can meet the different water use requirements of the user.

[0018] As a further improvement of the above technical solution, the second water pump is arranged between the outlet end of the heating device and the inlet ends of the first branch and the second branch, and the first water pump is arranged on the first branch or the second branch. By adjusting the second water pump, the water flow rate entering the water circuit system of the warm water dispenser can be adjusted, thereby adjusting the water outlet speed, and by adjusting the first water pump to adjust the flow rate of one of the first branch or the second branch, the purpose of adjusting the water outlet temperature at the water outlet pipe can be achieved.

[0037] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model. Each technical feature in the present utility model can be combined interactively on the premise of not conflicting with each other.

[0038] In a first aspect, an embodiment of the present utility model provides a warm water machine water circuit system, which is applied to a warm water machine and can provide drinkable warm water or hot water for users to meet the drinking water needs of users.

[0039] In this embodiment, the warm water machine water circuit system includes a water inlet pipe 100, a heat exchanger 200, a heating device 300, a water outlet pipe 600, and a first water pump 700.

[0040] The water inlet pipe 100 is used to supply cold water to the entire warm water dispenser water circuit. Its inlet end can be directly connected to a faucet or can also be connected to the water tank 110. In this embodiment, the inlet end of the water inlet pipe 100 is provided with the water tank 110. The water tank 110 is used for storing water. The warm water dispenser water circuit system with the water tank 110 does not need to be externally connected to a water pipe or placed close to a water source, making the placement position of the warm water dispenser using the warm water dispenser water circuit system of this embodiment more flexible.

[0041] In this embodiment, the heat exchanger 200 is used for heat exchange. It includes a cold water channel 210 and a hot water channel 220. The cold water channel 210 and the hot water channel 220 each have an inlet end and an outlet end. Among them, the inlet end of the cold water channel 210 is connected to the outlet end of the water inlet pipe 100. The inlet end of the heating device 300 is connected to the outlet end of the cold water channel 210 of the heat exchanger 200. The heating device 300 is used to heat cold water. High-temperature heating can disinfect and sterilize the cold water and turn the cold water into boiling water that can be drunk by users.

[0042] In this embodiment, the outlet end of the heating device 300 is provided with two branches, namely the first branch 400 and the second branch 500. Among them, the hot water channel 220 of the heat exchanger 200 is arranged in the first branch 400, that is, the hot water channel 220 is a part of the first branch 400. The outlet end of the hot water channel 220 is connected to the water outlet pipe 600 through the first branch 400, and the second branch 500 is directly connected to the water outlet pipe 600.

[0043] In this embodiment, after the hot water heated by the heating device 300 enters the hot water channel 220 through the first branch 400, it can exchange heat with the cold water in the cold water channel 210 of the heat exchanger 200. The water temperature in the hot water channel 220 decreases, while the water temperature in the cold water channel 210 increases.

[0044] It can be understood that the hot water cooled by the heat exchanger 200 is converted into warm water. The warm water flows through the first branch 400 to the water outlet pipe 600 and converges with the hot boiling water in the second branch 500 at the inlet end of the water outlet pipe 600, enabling the water outlet to flow out drinking water at a moderate temperature.

[0045] It can be understood that after the cold water enters the cold water channel 210, due to heat exchange with the hot water in the hot water channel 220, the temperature of the cold water rises before entering the heating device 300, that is, the cold water is pre-heated in the heat exchanger 200, which can reduce the energy consumption of the heating device 300 and save resources.

[0046] In this embodiment, the heat exchanger 200 is a surface heat exchanger, which includes a heat transfer wall surface. The cold water channel 210 and the hot water channel 220 are separated by the heat transfer wall surface and exchange heat through the heat transfer wall surface, and the flow of cold water and hot water will not affect each other. It can be understood that the structure of the heat exchanger 200 can be a shell-and-tube type, a sleeve type, and other structural forms, which are not specifically limited herein.

[0047] It should be noted that the warm water machine water path system in this embodiment further includes a first water pump 700. The first water pump 700 is used to control the water flow rate of the first branch 400 or the second branch 500, so as to control the water temperature at the outlet of the water outlet pipe 600 to meet the drinking water needs of users.

[0048] During the temperature adjustment process, there is no need for the user to manually adjust the mixing ratio of cold and hot water. The first water pump 700 adjusts the water flow rates of the first branch 400 and the second branch 500 according to the temperature required by the user, so that a suitable mixing ratio is achieved between the warm water and the hot water at the water outlet pipe 600 to meet the user's needs.

[0049] In some embodiments, two first water pumps 700 are provided. One of the first water pumps 700 is provided on the first branch 400, that is, between the inlet end and the outlet end of the first branch 400, and the other first water pump 700 is provided on the second branch 500, that is, between the inlet end and the outlet end of the second branch 500. Refer to Figure 1 , Figure 1 The direction of the arrow in is the water flow direction.

[0050] The first water pump 700 located on the first branch 400 can be provided between the inlet end of the hot water channel 220 and the inlet end of the first branch 400, or can be provided between the outlet end of the hot water channel 220 and the water outlet pipe 600.

[0051] It can be understood that when the first water pump 700 on the first branch 400 and the first water pump 700 on the second branch 500 are turned on, the heated hot water has a first temperature. The hot water with the first temperature flows through the first branch 400 and the second branch 500 respectively. The hot water flowing through the first branch 400 enters the heat exchanger 200 and decreases by a certain temperature, and is converted into warm water with a second temperature. The hot water flowing through the second branch 500 directly flows to the water outlet pipe 600 and converges with the warm water flowing out of the heat exchanger 200 to form drinking water with a temperature suitable for users to drink. The set temperature of the drinking water is the third temperature.

[0052] When the first water pump 700 on the first branch 400 controls the flow rate on the first branch 400 to decrease, the hot water entering the first branch 400 decreases, that is, the water flow of the water body converted into warm water with the second temperature decreases, while the hot water entering the second branch 500 remains unchanged, the mixing ratio of hot water and warm water increases, and the water temperature at the water outlet pipe 600 rises, that is, the third temperature rises.

[0053] When the first water pump 700 on the first branch 400 controls the flow rate on the first branch 400 to increase, the hot water entering the hot water channel 220 increases, that is, the water flow of the water body converted into warm water with the second temperature increases, while the hot water entering the second branch 500 remains unchanged, the mixing ratio of hot water and warm water decreases, and the water temperature at the water outlet pipe 600 drops, that is, the third temperature drops.

[0054] When the first water pump 700 on the first branch 400 controls the flow rate on the first branch 400 to remain unchanged, and the first water pump 700 on the second branch 500 controls the flow rate on the second branch 500 to increase, then the hot water entering the hot water channel 220 remains unchanged, the hot water in the second branch 500 increases, the mixing ratio of hot water and warm water increases, and the water temperature at the water outlet pipe 600 rises, that is, the third temperature rises.

[0055] When the first water pump 700 on the first branch 400 controls the flow rate on the first branch 400 to remain unchanged, and the first water pump 700 on the second branch 500 controls the flow rate on the second branch 500 to decrease, then the hot water entering the hot water channel 220 remains unchanged, the hot water in the second branch 500 decreases, the mixing ratio of hot water and warm water decreases, and the water temperature at the water outlet pipe 600 drops, that is, the third temperature drops.

[0056] It can be understood that when the first water pump 700 on the first branch 400 is turned on and the first water pump 700 on the second branch 500 is turned off, the heated hot water cannot flow directly to the water outlet pipe 600 through the second branch 500, but can only flow through the first branch 400 and pass through the heat exchanger 200 to reduce the temperature by a certain amount and be converted into warm water with the second temperature, and finally flow to the water outlet pipe 600. The temperature of the drinking water flowing out of the outlet of the water outlet pipe 600 is the second temperature.

[0057] When the first water pump 700 on the second branch 500 is turned on and the first water pump 700 on the first branch 400 is turned off, the heated hot water cannot enter the heat exchanger 200 through the first branch 400, but can only flow directly to the water outlet pipe 600 through the second branch 500. Therefore, the hot water with the first temperature directly flows out through the water outlet pipe 600 for users to use.

[0058] It can be seen that the first temperature here is greater than the third temperature, the third temperature is greater than the second temperature, the second temperature is greater than the water temperature of the cold water in the water inlet pipe 100, and the third temperature is adjusted within the range between the first temperature and the second temperature.

[0059] In some other embodiments, the warm water machine water circuit system further includes a second water pump 800. The second water pump 800 is disposed on the pipe before the diversion of the first branch 400 and the second branch 500, that is, between the inlet end of the water inlet pipe 100 and the inlet ends of the first branch 400 and the second branch 500, and is used to control the water flow rate of the pipe before the diversion.

[0060] In some embodiments, the second water pump 800 is disposed on the water inlet pipe 100, that is, between the inlet end and the outlet end of the water inlet pipe 100, and the first water pump 700 is disposed on the first branch 400 or the second branch 500, that is, only one first water pump 700 is provided. With such a setting, the second water pump 800 can control the water flow rate in the water inlet pipe 100 and can also control the water flow rate of the second branch 500 or the first branch 400 where the first water pump 700 is not provided.

[0061] Further, the second water pump 800 is disposed on the water inlet pipe 100, and the first water pump 700 is disposed on the first branch 400. Refer to Figure 2 and Figure 3 , Figure 2 and Figure 3 The arrow directions in

[0062] are the water flow directions. Figure 2 It can be understood that the first water pump 700 located on the first branch 400 can be disposed between the inlet end of the hot water channel 220 and the inlet end of the first branch 400. Refer to Figure 3 .

[0063] Refer to Figure 3 When both the second water pump 800 and the first water pump 700 on the first branch 400 are turned on, the water in the water tank 110 enters the heat exchanger 200 through the water inlet pipe 100, and exchanges heat with the hot water in the cold water channel 210 and the hot water channel 220 to achieve preheating. Then, it flows into the heating device 300 and is heated to a potable state. The heated hot water is diverted through the first branch 400 and the second branch 500. The hot water flowing through the first branch 400 exchanges heat through the heat exchanger 200 and the temperature is reduced, and then flows through the first water pump 700 and converges with the hot water of the second branch 500 at the water outlet pipe 600. The water temperature flowing out of the water outlet pipe 600 is the third temperature.

[0064] Adjust the second water pump 800 and keep the flow rate of the first water pump 700 on the first branch 400 unchanged, and keep the flow rate of the warm water entering the water outlet pipe 600 unchanged. The flow rate of the water entering the water inlet pipe 100 and the flow rate of the hot water entering the second branch 500 are adjusted by the second water pump 800, so that the mixing ratio of the warm water and the hot water can be changed, and the water temperature of the water outlet pipe 600 can be adjusted.

[0065] Keep the flow rate of the second water pump 800 unchanged, adjust the first water pump 700 on the first branch 400, keep the flow rate of the water entering the water inlet pipe 100 unchanged, and adjust the flow rate of the hot water entering the first branch 400 by the first water pump 700. When the flow rate in the first branch 400 increases, the flow rate in the second branch 500 decreases, the mixing ratio of the hot water and the warm water decreases, and the water temperature of the water outlet pipe 600 decreases; when the flow rate in the first branch 400 decreases, the flow rate in the second branch 500 increases, the mixing ratio of the hot water and the warm water increases, and the water temperature of the water outlet pipe 600 increases.

[0066] It can be understood that since the first water pump 700 is arranged between the outlet end of the hot water channel 220 and the inlet end of the water outlet pipe 600, after the hot water entering the first branch 400 is heat-exchanged by the heat exchanger 200, the flow rate is adjusted by the first water pump 700, and the first water pump 700 is more sensitive to adjusting the flow rate of the warm water entering the water outlet pipe 600.

[0067] When the second water pump 800 is turned on and the first water pump 700 is turned off, the hot water heated by the heating device 300 does not flow to the first branch 400 but all passes through the second branch 500 to reach the water outlet pipe 600, and the water outlet pipe 600 flows out the hot water heated by the heating device 300.

[0068] It can be understood that when the second water pump 800 is turned on, cold water can flow through the water inlet pipe 100 to reach the heat exchanger 200. When the second water pump 800 is turned off, the cold water cannot enter the heat exchanger 200 through the water inlet pipe 100, and the water flow cannot reach the water outlet pipe 600. After all the water in the pipelines of the warm water machine water circuit system is drained through the water outlet pipe 600, there is no residual stale water in each pipeline of the warm water machine water circuit system, which avoids the waste of water resources and also ensures the drinking water quality for the next use.

[0069] The second water pump 800 is arranged on the water inlet pipe 100, and the first water pump 700 is arranged on the second branch 500. Refer to Figure 4 , Figure 4 The direction of the arrow in is the water flow direction.

[0070] Adjust the second water pump 800 and keep the flow rate of the first water pump 700 on the second branch 500 unchanged, and keep the hot water flow rate entering the water outlet pipe 600 unchanged. The flow rate of the water entering the water inlet pipe 100 and the hot water flow rate entering the first branch 400 are adjusted by the second water pump 800, so that the mixing ratio of warm water and hot water can be changed to realize the water temperature adjustment of the water outlet pipe 600.

[0071] Keep the flow rate of the second water pump 800 unchanged, adjust the first water pump 700 on the second branch 500, keep the flow rate of the water entering the water inlet pipe 100 unchanged, and adjust the hot water flow rate entering the second branch 500 by the first water pump 700. When the flow rate in the second branch 500 increases, the flow rate in the first branch 400 decreases, the mixing ratio of hot water and warm water increases, and the water temperature of the water outlet pipe 600 rises; when the flow rate in the second branch 500 decreases, the flow rate in the first branch 400 increases, the mixing ratio of hot water and warm water decreases, and the water temperature of the water outlet pipe 600 drops.

[0072] When the second water pump 800 is turned on and the first water pump 700 is turned off, the hot water heated by the heating device 300 does not flow into the second branch 500 but all passes through the first branch 400 to reach the water outlet pipe 600, and the warm water cooled by the heat exchanger 200 flows out of the water outlet pipe 600.

[0073] In some other embodiments, the second water pump 800 is arranged between the inlet end and the outlet end of the water inlet pipe 100, and there are two first water pumps 700, which are respectively arranged on the first branch 400 and the second branch 500. Among them, the first water pump 700 located on the first branch 400 can be arranged between the inlet end of the hot water channel 220 and the inlet end of the first branch 400, referring to Figure 5 ; the first water pump 700 located on the first branch 400 can also be arranged between the outlet end of the hot water channel 220 and the water outlet pipe 600, referring to Figure 6 . Figure 5 and Figure 6 The arrow directions in

[0074] The second water pump 800 is used to control the water body flow rate entering the water inlet pipe 100, the first water pump 700 on the first branch 400 is used to control the hot water flow rate entering the first branch 400, and the first water pump 700 on the second branch 500 is used to control the hot water flow rate entering the second branch 500.

[0075] After turning on the second water pump 800, by adjusting the first water pump 700 on the first branch 400 and the first water pump 700 on the second branch 500, the adjustment of the ratio of hot water and warm water is realized, so as to change the water outlet temperature of the water outlet pipe 600 to meet the requirements of users.

[0076] In some other embodiments, the second water pump 800 is disposed on the pipeline between the outlet end of the heating device 300 and the inlet ends of the first branch 400 and the second branch 500, and the first water pump 700 is disposed on the first branch 400 or the second branch 500.

[0077] With such an arrangement, when the second water pump 800 is closed, water flow cannot flow from the outlet end of the heating device 300 to the first branch 400 or the second branch 500, and a certain amount of water is retained in the heating device 300, preventing the heating device 300 from dry burning, playing a certain protective role for the heating device 300, and improving the service life of the warm water dispenser.

[0078] Based on the above embodiments, further, the first water pump 700 is disposed on the first branch 400. Refer to Figure 7 , Figure 7 where the arrow direction in

[0079] is the water flow direction. Adjust the second water pump 800 and keep the flow rate of the first water pump 700 on the first branch 400 unchanged. The flow rate of the warm water entering the water outlet pipe 600 remains unchanged, while the flow rate of the water entering the water inlet pipe 100 and the flow rate of the hot water entering the second branch 500 are adjusted by the second water pump 800, so as to be able to change the mixing ratio of the warm water and the hot water and achieve the temperature adjustment of the water in the water outlet pipe 600.

[0080] Keep the flow rate of the second water pump 800 unchanged and adjust the first water pump 700 on the first branch 400. The flow rate of the water entering the water inlet pipe 100 remains unchanged, while the flow rate of the hot water entering the first branch 400 is adjusted by the first water pump 700. When the flow rate in the first branch 400 increases, the flow rate in the second branch 500 decreases, the mixing ratio of the hot water and the warm water decreases, and the water temperature in the water outlet pipe 600 decreases; when the flow rate in the first branch 400 decreases, the flow rate in the second branch 500 increases, the mixing ratio of the hot water and the warm water increases, and the water temperature in the water outlet pipe 600 increases.

[0081] When the second water pump 800 is turned on and the first water pump 700 is turned off, the hot water heated by the heating device 300 does not flow to the first branch 400 but all passes through the second branch 500 to reach the water outlet pipe 600, and the water outlet pipe 600 discharges the hot water heated by the heating device 300.

[0082] When the second water pump 800 is disposed on the pipeline between the outlet end of the heating device 300 and the inlet ends of the first branch 400 and the second branch 500, and the first water pump 700 is disposed on the second branch 500. Refer to Figure 8 , Figure 8 where the arrow direction in

[0083] Adjust the second water pump 800 and keep the flow rate of the first water pump 700 on the second branch 500 unchanged, and keep the hot water flow rate entering the water outlet pipe 600 unchanged. The flow rate of the water entering the water inlet pipe 100 and the hot water flow rate entering the first branch 400 are adjusted by the second water pump 800, so as to change the mixing ratio of warm water and hot water and realize the temperature adjustment of the water outlet pipe 600.

[0084] Keep the flow rate of the second water pump 800 unchanged, adjust the first water pump 700 on the second branch 500, keep the flow rate of the water entering the water inlet pipe 100 unchanged, and adjust the hot water flow rate entering the second branch 500 by the first water pump 700. When the flow rate in the second branch 500 increases, the flow rate in the first branch 400 decreases, the mixing ratio of hot water and warm water increases, and the water temperature of the water outlet pipe 600 rises; when the flow rate in the second branch 500 decreases, the flow rate in the first branch 400 increases, the mixing ratio of hot water and warm water decreases, and the water temperature of the water outlet pipe 600 drops.

[0085] When the second water pump 800 is turned on and the first water pump 700 is turned off, the hot water heated by the heating device 300 does not flow to the second branch 500 but all passes through the first branch 400 to reach the water outlet pipe 600, and the warm water cooled by the heat exchanger 200 flows out of the water outlet pipe 600.

[0086] In some other embodiments, the second water pump 800 is arranged on the pipeline between the outlet end of the heating device 300 and the inlet ends of the first branch 400 and the second branch 500, and two first water pumps 700 are arranged. The two first water pumps 700 are respectively arranged on the first branch 400 and the second branch 500. Refer to Figure 9 , Figure 9 The direction of the arrow in is the water flow direction.

[0087] The second water pump 800 is used to control the water flow rate flowing out of the heating device 300, the first water pump 700 on the first branch 400 is used to control the hot water flow rate entering the first branch 400, and the first water pump 700 on the second branch 500 is used to control the hot water flow rate entering the second branch 500.

[0088] After turning on the second water pump 800, by adjusting the first water pump 700 on the first branch 400 and the first water pump 700 on the second branch 500, the adjustment of the ratio of hot water and warm water is realized, so as to change the water outlet temperature of the water outlet pipe 600 to meet the requirements of users.

[0089] In some embodiments, the waterway system of the warm and hot water dispenser further includes a temperature detector and a controller. The temperature detector is arranged on the water outlet pipe 600 and is used to detect the water temperature at the water outlet pipe 600. The first water pump 700 and the temperature detector are respectively electrically connected to the controller.

[0090] The water temperature at the water pipe 600 can be detected by the temperature detector, and the first water pump 700 is controlled by the controller to intelligently adjust the flow rate of the first branch 400 or the second branch 500, so as to intelligently adjust the water temperature of the outlet pipe 600 to meet the needs of users.
