Description

Technical Field

[0001] This utility model relates to the technical field of water boilers, specifically to a preheating high-flow-rate water boiler. Background Technology

[0002] Existing water dispensers generally heat room temperature water directly to boiling. Because there is a large temperature difference between room temperature water and boiling water, and the power of the water dispenser is relatively fixed, users need to wait a relatively long time, or the water dispenser cannot provide enough hot water in a relatively short time, which affects the user experience.

[0003] Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a preheating high-flow-rate water dispenser that can relatively shorten the user's waiting time and relatively increase the maximum water output, thereby improving the user's experience.

The circulating heating module includes an instant heating module and a water circulation component for circulating water within the circulating heating module through the instant heating module. The circulating heating module has an external water inlet and an external water outlet. The external water inlet is connected to an inlet valve for controlling the entry of new external water into the circulating heating module. The external water outlet is equipped with a reversing valve assembly. The electrical control device is electrically connected to the instant heating module and the reversing valve assembly, respectively. The electrical control device guides the water flow to circulate within the circulating heating module or to discharge it externally through the reversing valve assembly.

[0007] As a specific embodiment, the circulating heating module further includes a water storage tank, which has a water tank outlet, a fresh water inlet, and a circulating water inlet. An external water inlet is located at the fresh water inlet of the water storage tank. The water tank outlet is connected to the water inlet of the instant heating module. The water outlet of the instant heating module is connected to the water inlet of the reversing valve assembly. The reversing valve assembly has a first water outlet and a second water outlet for supplying water externally. The first water outlet of the reversing valve assembly is connected to the circulating water inlet of the water storage tank.

[0008] As a specific embodiment, the water storage tank is equipped with a water tank temperature control probe and a water level probe, the water inlet valve is a water inlet solenoid valve, and the electrical control device is electrically connected to the water inlet solenoid valve, the water tank temperature control probe and the water level probe respectively.

[0009] As a specific embodiment, the water outlet end and / or the water outlet end of the instant heating module is equipped with a circulating water temperature control probe, which is electrically connected to the electrical control device.

[0010] As a specific embodiment, the circulating heating module further includes a water pump and a stepping regulating valve.

[0013] The beneficial effects of this utility model are:

[0014] The circulating heating module preheats the water before the user demands hot water. When the user starts demanding hot water, the instant heating module heats the relatively hot water in the circulating heating module, thus shortening the user's waiting time. At the same time, because the water temperature in the circulating heating module is relatively high, the instant heating module with the same power can heat more hot water, increasing the maximum hot water output of the water dispenser.

[0021] Figure 7This is a flowchart illustrating the third embodiment of the present invention. Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] First embodiment:

[0024] See Figures 1-4 This preheating high-flow-rate water dispenser includes an electronic control unit and a circulating heating module. The circulating heating module includes an instant heating module and a water circulation component for circulating water within the instant heating module 1 through the instant heating module. The circulating heating module has an external water inlet and an external water outlet. The external water inlet is connected to an inlet valve 2 for controlling the entry of new external water into the circulating heating module, and the external water outlet is equipped with a reversing valve assembly 3. The electronic control unit is electrically connected to the instant heating module 1 and the reversing valve assembly 3, respectively. The electronic control unit guides the water flow to circulate within the circulating heating module or to discharge it externally through the reversing valve assembly 3. The circulating heating module can preheat the water temperature before the user demands hot water. When the user demands hot water, the instant heating module 1 can heat the relatively high-temperature water in the circulating heating module, thereby relatively shortening the user's waiting time. At the same time, because the water temperature in the circulating heating module is relatively high, the instant heating module 1 with the same power can heat more hot water, enabling the water dispenser to relatively increase the maximum hot water output and improve the user experience.

[0025] As the water circulates within the circulating heating module, its temperature gradually increases, ensuring a continuous flow of relatively warm water within the module, thus achieving a certain disinfection and sterilization effect.

[0026] Furthermore, the circulating heating module also includes a water storage tank 4, which has a water tank outlet 41, a fresh water inlet 42, and a circulating water inlet 43. An external water inlet is located at the fresh water inlet 42 of the water storage tank 4. The water tank outlet 41 of the water storage tank 4 is connected to the water inlet of the instant heating module 1, and the water outlet of the instant heating module 1 is connected to the water inlet of the reversing valve assembly 3. The reversing valve assembly 3 has a first water outlet 31 and a second water outlet 32 ​​for supplying water externally. The first water outlet 31 of the reversing valve assembly 3 is connected to the circulating water inlet 43 of the water storage tank 4. The water storage tank 4 can further increase the water storage capacity of the circulating heating module, so that the water dispenser can store more relatively high-temperature warm water, further increasing the maximum hot water output.

[0027] Furthermore, the water storage tank 4 is equipped with a water tank temperature control probe 45 and a water level probe 46, the water inlet valve 2 is a water inlet solenoid valve, and the electrical control device is electrically connected to the water inlet solenoid valve, the water tank temperature control probe 45 and the water level probe 46 respectively.

[0028] The water tank temperature control probe 45 can more accurately detect whether the water temperature in the water storage tank 4 has reached the preset preheating temperature.

[0029] The water level probe 46 can detect the amount of water stored in the water tank 4, thus preventing dry burning.

[0030] Furthermore, the outlet end and / or the outlet end of the instant heating module 1 are equipped with a circulating water temperature control probe 11. The circulating water temperature control probe 11 is electrically connected to the electronic control device to improve the detection of the water temperature passing through the instant heating module 1, so that the accuracy of the outlet water temperature detected by the equipment is higher.

[0031] Furthermore, the circulating heating module also includes a water pump 51 and a stepping regulating valve 52. The water outlet 41 of the water storage tank 4 is connected to the water inlet of the water pump 51. The water outlet of the water pump 51 is connected to the water inlet of the stepping regulating valve 52. The water outlet of the stepping regulating valve 52 is connected to the water inlet of the instant heating module 1. A flow meter 53 is provided between the water outlet of the stepping regulating valve 52 and the water inlet of the instant heating module 1. The electrical control device is electrically connected to the flow meter 53, the water pump 51 and the stepping regulating valve 52 respectively.

[0032] The water pump 51 can provide power for water circulation or external water supply. When hot water needs to be supplied externally, the step regulating valve 52 can control the water flow through the instant heating module 1, thereby improving the efficiency of water temperature rise.

[0033] When hot water needs to be supplied externally, the flow meter 53 can start working, improving the accuracy of the hot water supply flow rate.

[0034] Furthermore, the second outlet 32 ​​of the reversing valve assembly 3 is provided with a water storage container 6. The water storage container 6 has an outlet 61. The outlet 61 is provided with a switch 62. The switch 62 is connected to an outlet stepper motor 63 for controlling the opening or closing of the outlet 61. Tea can be added to the water storage container 6 for brewing. After brewing, the outlet is opened by the outlet stepper motor 63 to let the tea soup flow out.

[0035] Furthermore, the second outlet 32 ​​of the reversing valve assembly 3 is also equipped with a stirring motor 64. The stirring end of the stirring motor 64 extends into the inner side of the water storage container 6. The stirring motor 64 can stir the tea leaves and other soup ingredients in the water storage container 6, making the soup ingredients more uniform and the brewing effect better.

[0036] To heat water more efficiently, this utility model also discloses a water heating method, including the aforementioned preheating water machine, which heats water according to the following steps:

[0037] Step 1: Power on the machine and preset the preheating temperature of the water tank 4. The water level in the water tank 4 is detected by the water level probe 46. When the water level in the water tank 4 has not reached the preset position, the water inlet solenoid valve is opened until the water level rises to the preset position. When the water level in the water tank 4 reaches the preset position, the water inlet solenoid valve is closed, and the water tank temperature control probe 45 detects the water temperature in the water tank 4. When the water temperature in the water tank 4 has not reached the preheating temperature, proceed to Step 2. When the water temperature in the water tank 4 reaches the preheating temperature, proceed to Step 3.

[0038] During the process of preheating water and supplying hot water, no new water will enter the water storage tank 4 through the inlet solenoid valve, thus avoiding the impact of new water on the preheating efficiency and the efficiency of supplying hot water.

[0039] Step 2: The water pump 51 and the instant heating module 1 start working. The first water outlet 31 of the reversing valve assembly 3 is open, and the second water outlet 32 ​​of the reversing valve assembly 3 is closed. Water flows in the circulating heating module. When the water temperature in the water storage tank 4 reaches the preheating temperature, proceed to step 3.

[0040] This allows the water temperature in the water storage tank 4 to be relatively increased before the water dispenser provides hot water, thereby shortening the time required to heat the water to boiling point.

[0041] Step 3: Set the user's desired water temperature and water volume and start the water dispensing command. The water tank temperature control probe 45 detects the water temperature in the water storage tank 4. When the water temperature in the water storage tank 4 is lower than the preheating temperature, proceed to Step 4; when the water temperature in the water storage tank 4 is greater than or equal to the preheating temperature, proceed to Step 5.

[0042] Step 4: The first outlet 31 of the reversing valve assembly 3 is turned on, and the second outlet 32 ​​of the reversing valve assembly 3 is turned off. That is, the heating module 1 and the water pump 51 start to work, and the water flows in the circulating heating module until the water tank temperature control probe 45 detects that the water temperature is greater than or equal to the preheating temperature, and then proceeds to step 5.

[0043] In this embodiment, the water tank preheating temperature is 70°C, meaning that the water temperature in the water storage tank 4 must reach 75°C before proceeding to step five. Since the water will experience a certain temperature drop as it flows from the water storage tank 4 to the instant heating module 1, the actual water temperature in the water storage tank 4 is 5°C higher than the preheating temperature. This ensures that the water temperature will not be lower than the preheating temperature when it flows to the instant heating module 1, thus guaranteeing that the instant heating module 1 can successfully heat the water.

[0044] Step 5: The first outlet end 31 of the reversing valve assembly 3 is turned on, and the second outlet end 32 of the reversing valve assembly 3 is turned off. The instant heating module 1 and the outlet pump 51 start to work. The electronic control device controls the opening degree of the step regulating valve 52 and the power of the instant heating module 1 according to the preset outlet water temperature and outlet water volume. When the circulating water temperature control probe 11 detects that the water temperature is greater than the preset outlet water temperature, the process proceeds to step 6.

[0045] When the preset boiling water temperature is relatively high, the water flow rate can be reduced by adjusting the opening degree of the step regulating valve 52, while the power of the instant heating module 1 can be increased.

[0046] When the preset boiling water temperature is relatively low, the water flow rate can be increased by adjusting the opening degree of the step regulating valve 52, while the power of the instant heating module 1 can be reduced.

[0047] Step 5 also prevents the relatively low-temperature water from the outlet of the heating module 1 from being discharged directly before the water is discharged, thus making the water temperature more stable.

[0048] In this embodiment, the highest water temperature is 95°C. When the highest water temperature needs to be output, the water temperature flowing through the instant heating module 1 must reach 97°C before proceeding to step six. Since there is a certain distance between the instant heating module 1 and the second water outlet 32, the boiling water at 97°C will not be lower than the highest water temperature of 95°C when it flows to the second water outlet 32, even if it cools down a bit.

[0049] Step 6: The first outlet 31 of the reversing valve assembly 3 is cut off, the second outlet 32 ​​of the reversing valve assembly 3 is opened, the flow meter 53 starts counting, and the water pump 51 stops working after the set flow rate is reached, and the preheating water dispenser stops discharging water.

[0050] Furthermore, when the water temperature detected by the water tank temperature control probe 45 in step three is 5°C lower than the preheating temperature, the process proceeds to step four.

[0051] When the water temperature detected by the water tank temperature control probe 45 in steps three and four is greater than the preheating temperature by 5°C, the process proceeds to step five.

[0052] When the circulating water temperature control probe 11 detects that the water temperature is 2°C higher than the preset outlet water temperature in step five, it proceeds to step six.

[0053] In step two, you can set it to a circulating heating mode. In the circulating heating mode, step two will not proceed to step three.

[0054] Second embodiment:

[0055] See Figure 5 The difference between this embodiment and the first embodiment is that the reversing valve assembly 3 of this water heating method includes a bypass solenoid valve 33 and an outlet solenoid valve 34, which can be independently set. The bypass solenoid valve 33 and the outlet solenoid valve 34 are respectively set at the first outlet end 31 and the second outlet end 32 of the reversing valve assembly 3. By controlling the bypass solenoid valve and the outlet solenoid valve, the first outlet end 31 and the second outlet end 32 can switch between conducting and cutting off states.

[0056] The remaining undescribed parts are the same as in the first embodiment and will not be repeated here.

[0057] Third embodiment:

[0058] See Figure 6 , Figure 7 The difference between this embodiment and the first embodiment is that the water storage tank 4 of this water heating method is also provided with a water tank heating pipe 44. The electrical control device is electrically connected to the water tank heating pipe 44. The water tank heating pipe 44 can play an auxiliary heating role, so that the water temperature can reach the preset preheating temperature more quickly.

[0059] The preheating water heater heats water according to the following steps:

[0060] Step 1: Power on the machine and preset the preheating temperature of the water storage tank 4. The water level in the water storage tank 4 is detected by the water level probe 46. When the water level in the water storage tank 4 has not reached the preset position, the water inlet solenoid valve is opened until the water level rises to the preset position. When the water level in the water storage tank 4 reaches the preset position, the water inlet solenoid valve is closed, and the water tank temperature control probe 45 detects the water temperature in the water storage tank 4.

[0061] When the water temperature detected by the water tank temperature control probe 45 in step one is lower than the preheating temperature and the temperature difference between the two is greater than or equal to the temperature difference threshold, step one enters the cold start mode. In the cold start mode, the water tank heating tube 44 starts to work, that is, the heat module 1 and the water pump 51 are kept off until the water temperature in the water storage tank 4 reaches the preheating temperature and enters step three.

[0062] When the water temperature detected by the water tank temperature control probe 45 in step one is lower than the preheating temperature and the temperature difference between the two is less than the temperature difference threshold, step one proceeds to step two.

[0063] Step 2: The water pump 51 and the instant heating module 1 start to work. The first water outlet 31 of the reversing valve assembly 3 is open, and the second water outlet 32 ​​of the reversing valve assembly 3 is cut off. Water flows in the circulating heating module. When the water temperature in the water storage tank 4 reaches the preheating temperature, proceed to step 3.

[0064] Step 3: Set the user's desired water temperature and water volume and start the water dispensing command. The water tank temperature control probe 45 detects the water temperature in the water storage tank 4. When the water temperature in the water storage tank 4 is lower than the preheating temperature, proceed to Step 4; when the water temperature in the water storage tank 4 is greater than or equal to the preheating temperature, proceed to Step 5.

[0065] Step 4: The first outlet 31 of the reversing valve assembly 3 is turned on, and the second outlet 32 ​​of the reversing valve assembly 3 is turned off. That is, the heating module 1 and the water pump 51 start to work, and water flows in the circulating heating module until the water tank temperature control probe 45 detects that the water temperature is greater than or equal to the preheating temperature, and then proceed to step 5.

[0066] Step 5: The first outlet end 31 of the reversing valve assembly 3 is turned on, and the second outlet end 32 of the reversing valve assembly 3 is turned off. The instant heating module 1 and the water pump 51 start to work. The electronic control device controls the opening degree of the step regulating valve 52 and the power of the instant heating module 1 according to the preset outlet water temperature and outlet water volume. When the circulating water temperature control probe 11 detects that the water temperature is greater than the preset outlet water temperature, proceed to step 6.

[0067] Step 6: The first outlet 31 of the reversing valve assembly 3 is cut off, the second outlet 32 ​​of the reversing valve assembly 3 is opened, the flow meter 53 starts counting, and the water pump 51 stops working after the set flow rate is reached, and the preheating water dispenser stops discharging water.

[0068] The temperature difference threshold is 10℃.

[0069] For example, if the preheating temperature is set to 75℃, but the actual inlet water temperature does not reach 65℃, the machine will enter the cold start mode from step one. When the machine is started cold, such as when the equipment is used for the first time or when cold water is refilled after the whole machine is cleaned, the water temperature in the water storage tank 4 is generally much different from the preset preheating temperature, usually more than 10℃. In this case, internal circulation heating is not required, and the instant heating module 1 and the outlet water pump 51 do not need to be started. This avoids the situation where the instant heating module 1 and the outlet water pump 51 need to be started for a long time during cold start, which would shorten their lifespan. It also reduces continuous noise to a certain extent.

[0070] The remaining undescribed parts are the same as in the first embodiment and will not be repeated here.

[0071] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible.
