Description

A smart temperature- and flow-regulating water dispenser for cooling boiled water. Technical Field

[0001] This utility model relates to the field of drinking water equipment technology, specifically to an intelligent temperature- and flow-regulating boiled water drinking device. Background Technology

[0002] Water dispensers typically use heat exchange to produce cooled boiled water. Room temperature water is supplied from the dispenser's pressure tank or water tank through the cold water pipes of the heat exchanger to the bottom of the hot water tank. Hot water then flows from the top of the hot water tank through the heat exchanger's hot water pipes, where it exchanges heat with the cold water before being dispensed at the outlet. In current technology, the temperature of the cooled boiled water is usually adjusted by a mechanical mixing valve to regulate the ratio of hot or cold water entering the heat exchanger.

[0003] Water dispensers need to dispense boiled water at different temperatures depending on the season. The water temperature needs to be lower in summer and higher in winter for direct drinking. Additionally, school water dispensers typically have multiple taps, and different taps require different total water flow rates. Meeting these two requirements is essential for a good customer experience. However, current solutions require manual adjustment of the boiled water temperature and cannot automatically adjust according to seasonal changes. Furthermore, the water flow rate is also unadjustable; the flow is too high when a single tap is open and too low when multiple taps are open, resulting in a poor user experience. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model proposes an intelligent temperature and flow rate regulating device for cooled boiled water. It can intelligently adjust the temperature of the cooled boiled water according to seasonal changes or user needs, and can also intelligently adjust the flow rate of the cooled boiled water according to the number of taps opened.

[0005] To achieve the above objectives, the intelligent temperature- and flow-regulating boiled water dispenser of this utility model includes:

[0006] Ambient temperature water tank, used to store ambient temperature water;

[0007] A hot water tank can heat the water stored inside;

[0008] A heat exchanger, which is connected to a room temperature water tank and a hot water tank, is used to exchange heat between room temperature water in the room temperature water tank and hot water in the hot water tank to obtain cooled boiled water at a certain temperature.

[0009] At least one faucet is connected to a heat exchanger via a pipe for cooled boiled water.

[0010] The intelligent controller can intelligently adjust the temperature and flow rate of cooled boiled water.

[0011] In one embodiment, the heat exchanger includes a first heat exchange channel and a second heat exchange channel. The inlet of the first heat exchange channel is connected to the outlet of the ambient temperature water tank, and the outlet of the first heat exchange channel is connected to the inlet of the hot water tank. The inlet of the second heat exchange channel is connected to the outlet of the hot water tank, and the outlet of the second heat exchange channel is connected to the cooled boiled water outlet pipe.

[0012] In one embodiment, a normal temperature water outlet pump and a first water valve are provided on the first heat exchange channel, and a hot water outlet pump is provided on the second heat exchange channel.

[0013] In one embodiment, the boiled water cooling equipment also includes a hot water tank replenishment pipeline connected in parallel with the first heat exchange channel, and the hot water tank replenishment pipeline is equipped with a replenishment pump and a replenishment valve.

[0014] In one embodiment, the boiled water cooling device further includes a boiled water cooling circulation pipeline, the inlet of which is connected to the boiled water cooling outlet pipeline, and the outlet of which is connected to the inlet of the hot water tank or leads to the outside of the boiled water cooling device.

[0015] In one embodiment, the cooled boiled water drinking equipment also includes a drain pipe connected to the first heat exchange channel.

[0016] In one embodiment, the ambient temperature water tank is equipped with an ambient temperature water tank temperature probe for detecting the temperature of ambient temperature water; the hot water tank is equipped with a first hot water tank temperature probe and a second hot water tank temperature probe for detecting the temperature of hot water at the low and high positions of the hot water tank, respectively; and the cooled boiled water outlet pipe is equipped with a cooled boiled water temperature probe for detecting the temperature of cooled boiled water.

[0017] Beneficial effects:

[0018] (1) The boiled water drinking device of this utility model has an intelligent controller that can intelligently adjust the temperature and flow rate of the boiled water, so that the temperature of the boiled water can always meet the user's needs, and the flow rate of the boiled water can match the number of faucets opened, thus solving the problem that the water temperature adjustment is not intelligent and the flow rate of the boiled water cannot match the number of faucets opened in the prior art.

[0019] (2) The water drinking equipment of this utility model has a cooled boiled water circulation pipeline. When the water temperature in the cooled boiled water outlet pipeline is lower than the required temperature, the water in the cooled boiled water outlet pipeline is drained into the hot water tank or discharged from the water drinking equipment, so that the water in the cooled boiled water outlet pipeline is always kept at the temperature required by the user. Thus, the first cup of water that the user receives from the tap is cooled boiled water at the required temperature, realizing a "zero cold water" water drinking equipment.

[0025] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.

[0026] This utility model discloses an intelligent temperature- and flow-regulating boiled water dispenser. The dispenser includes a room-temperature water tank, a hot water tank, a heat exchanger, at least one faucet, and an intelligent controller. The room-temperature water tank stores room-temperature water; the hot water tank heats the water stored therein; the heat exchanger connects to both the room-temperature and hot water tanks to exchange heat between the room-temperature water and the hot water, thus obtaining boiled water at a certain temperature; the faucet is connected to the heat exchanger via a boiled water outlet pipe; and the intelligent controller intelligently adjusts the temperature and flow rate of the boiled water.

[0027] The aforementioned boiled water drinking device intelligently adjusts the water temperature and flow rate of the boiled water through a smart controller, thereby enabling the device to provide boiled water at different temperatures under different climatic conditions and to meet users' special needs for water temperature. Furthermore, when multiple taps are available, the flow rate of the boiled water provided by the device matches the number of taps that are turned on, solving the problem in the prior art where the flow rate is high when a single tap is turned on and low when multiple taps are turned on.

[0028] Figure 1 shows the preferred embodiment of this utility model. The cooled boiled water drinking device includes a room temperature water tank 1, a hot water tank 2, a heat exchanger 3, at least one faucet 4, and an intelligent controller.

[0029] A room temperature water tank 1 is used to store room temperature water. Preferably, the room temperature water is pure water filtered from tap water by a filtration device. The room temperature water tank 1 has an inlet 1a and an outlet 1b. The inlet 1a is connected to the pure water outlet of the filtration device, allowing pure water from the filtration device to enter and be stored in the room temperature water tank 1. The outlet 1b allows the room temperature water in the room temperature water tank 1 to flow out and then into the heat exchanger 3 for heat exchange, or into the hot water tank 2 to replenish the hot water tank 2. A room temperature water tank temperature probe 11 is provided in the room temperature water tank 1 to detect the temperature of the room temperature water. An exhaust port 12 is provided at the top of the room temperature water tank 1, allowing gas in the room temperature water tank 1 to escape from the exhaust port 12, and allowing excess water to overflow from the exhaust port 12 when the room temperature water tank 1 is full. Preferably, the room temperature water tank 1 is provided with a sterilization device 13, such as UV sterilization technology, for sterilizing the room temperature water. The ambient temperature water tank 1 is also equipped with a liquid level probe 15, which is used to detect the liquid level of ambient temperature water in the ambient temperature water tank.

[0030] Hot water tank 2 is used to store hot water and has the function of heating the stored water. Hot water tank 2 has an inlet 2a and an outlet 2b. The inlet 2a is indirectly connected to the outlet 1b of the ambient temperature water tank 1, allowing ambient temperature water in the ambient temperature water tank 1 to enter the hot water tank 2 through the inlet 2a. The specific method of this indirect connection will be described below. The outlet 2b allows the hot water in the hot water tank 2 to flow out and then into the heat exchanger 3 for heat exchange. A heating device 20 is installed at the bottom of the hot water tank 2 to heat the water inside. Preferably, the heating device 20 heats the water in the hot water tank 2 to boiling point, and then exchanges heat with the ambient temperature water in the ambient temperature water tank 1 to achieve the desired temperature of cooled boiled water. Therefore, the water provided by this drinking water device is boiled water that has been cooled. Of course, as an optional method, the heating device 20 can also be set to heat the water to the desired temperature, and is not limited to heating it to boiling point.

[0031] The hot water tank 2 is equipped with a first hot water tank temperature probe 21 and a second hot water tank temperature probe 22, located at the low and high positions within the hot water tank 2, respectively, to detect the temperature of the hot water at the low and high positions. The inlet 2a is preferably located at the bottom of the hot water tank 2. Therefore, the water temperature at the low position is usually lower than the water temperature at the high position. Therefore, setting temperature probes at both the low and high positions allows for more accurate measurement of the hot water temperature. Also, because the water temperature at the high position is usually higher than the water temperature at the low position, the outlet 2b is connected to a water intake pipe 23 on one side inside the hot water tank 2. The water intake pipe 23 extends from the outlet 2b at the bottom to the high position of the hot water tank 2, ensuring that the water flowing from the outlet 2b is preferentially drawn from the relatively warmer hot water at the high position. This makes it easier to obtain the desired cooled boiled water temperature and to obtain more cooled boiled water when entering the heat exchanger 3 for heat exchange. The top of the hot water tank 2 is equipped with an exhaust port 24, which serves the same purpose as the exhaust port 12 of the ambient temperature water tank 1, for venting and overflow. The hot water tank 2 is also equipped with a liquid level probe 25, which is used to detect the liquid level of the hot water in the hot water tank.

[0032] A heat exchanger 3 is provided between the ambient temperature water tank 1 and the hot water tank 2. The heat exchanger 3 is connected to both tanks and is used to exchange heat between the ambient temperature water in the ambient temperature water tank 1 and the hot water in the hot water tank 2 to obtain cooled boiled water at a certain temperature. Specifically, the heat exchanger 3 includes a first heat exchange channel 31 and a second heat exchange channel 32. The inlet 31a of the first heat exchange channel 31 is connected to the outlet 1b of the ambient temperature water tank 1, and the outlet 31b of the first heat exchange channel 31 is connected to the inlet 2a of the hot water tank 2. The inlet 32a of the second heat exchange channel 32 is connected to the outlet 2b of the hot water tank 2, and the outlet 32b of the second heat exchange channel 32 is the cooled boiled water outlet. A portion of the first heat exchange channel 31 is located around a portion of the second heat exchange channel 32, enclosing it. This enclosing section forms the core of the heat exchanger 3. Within this enclosing section, the hot water inside exchanges heat with the ambient temperature water outside, lowering the temperature of the hot water to obtain cooled boiled water. During heat exchange, ambient temperature water flows through the first heat exchange channel 31 to the heat exchanger 3, then into the hot water tank 2. The hot water flows through the second heat exchange channel 32 to the heat exchanger 3, where it exchanges heat with the ambient temperature water within the enclosing section of the heat exchanger 3 to form cooled boiled water.

[0033] The first heat exchange channel 31 is equipped with a room temperature water outlet pump 311 and a first water valve 312. The room temperature water outlet pump 311 is used to control the flow rate of room temperature water in the first heat exchange channel 31 to the heat exchanger 3, and the first water valve 312 is used to control whether the first heat exchange channel 31 is open or closed. The second heat exchange channel 32 is equipped with a hot water outlet pump 321, which is used to control the flow rate of hot water in the second heat exchange channel 32 to the heat exchanger 3.

[0034] The outlet 32b of the second heat exchange channel 32 leads to a tap 4 that provides cooled boiled water to the user. A cooled boiled water outlet pipe 5 is located between the outlet and the tap 4. A cooled boiled water temperature probe 50 is installed on this pipe 5 to detect the temperature of the cooled boiled water after heat exchange. The cooled boiled water drinking equipment has at least one tap 4. In some applications, such as on a school campus, the equipment may have multiple taps 4. In the embodiment shown in Figure 1, the equipment has four taps, each with a dispensing valve 40 for controlling the opening and closing of the tap.

[0035] This utility model's cooled boiled water drinking device also includes a cooled boiled water circulation pipe 6. The inlet 6a of the cooled boiled water circulation pipe 6 is connected to the cooled boiled water outlet pipe 5, and the outlet 6b of the cooled boiled water circulation pipe 6 is connected to the inlet 2a of the hot water tank 2. A circulation valve 60 is installed on the cooled boiled water circulation pipe 6 to control the flow of the pipe. When the cooled boiled water temperature in the cooled boiled water outlet pipe 5 is lower than the required temperature, typically when the drinking device has not been used for a long time, the intelligent controller controls the circulation valve 60 to open, allowing the water in the cooled boiled water outlet pipe 5 to flow into the hot water tank 2 through the cooled boiled water circulation pipe 6 for reheating. This ensures that there is no cooled boiled water in the cooled boiled water outlet pipe 5 that is not at the required temperature, thus preventing the user from getting an unsuitable temperature for the first cup of cooled boiled water from the tap, achieving a "zero cold water" cooled boiled water drinking device.

[0036] The cooled boiled water drinking water equipment also includes a hot water tank replenishment pipe 7, which is connected in parallel with the first heat exchange channel 31. The inlet of the hot water tank replenishment pipe 7 is connected to the outlet 1b of the ambient temperature water tank 1, and the outlet of the hot water tank replenishment pipe 7 is connected to the inlet 2a of the hot water tank 2, for replenishing water to the hot water tank 2, so that the hot water tank 2 always maintains a certain water volume. The hot water tank replenishment pipe 7 is equipped with a water replenishment pump 71 and a water replenishment valve 72. The water replenishment pump 71 is used to control the directional flow of water in the pipe, and the water replenishment valve 72 is used to control whether the pipe is open or closed.

[0037] The cooled boiled water drinking equipment also includes a drain pipe 8, which is connected to the outlet of the first heat exchange channel 31, and also to the outlet of the hot water tank replenishment pipe 7 and the inlet 2a of the hot water tank 2. This drain pipe is used to drain the water from the entire drinking water equipment, preventing bacterial growth due to prolonged stagnant water when the equipment is not in use for extended periods. A drain valve 80 is installed on the drain pipe 8 to control its flow.

[0038] The above-mentioned boiled water device can intelligently adjust the temperature and flow rate of boiled water to meet the different temperature requirements of boiled water in different seasons, and can match the different total water output requirements when different numbers of taps are turned on, thereby improving the user experience.

[0039] This utility model also proposes a control method for an intelligent temperature- and flow-regulating boiled water device, comprising the following steps:

[0040] The user inputs the desired temperature T of cooled boiled water through the operating interface connected to the smart controller, and the smart controller stores the desired temperature T of cooled boiled water.

[0041] The intelligent controller obtains the hot water temperature T1 of the hot water tank, the ambient water temperature T2 of the ambient water tank, and the number of faucets opened N;

[0042] Adjust the flow rate Q1 of hot water into the heat exchanger according to the number of faucets N opened, so that it matches the number of faucets N opened.

[0043] The flow rate Q1 of hot water entering the heat exchanger is determined based on the hot water temperature T1 in the hot water tank, the ambient water temperature T2 in the ambient water tank, and the required cooled boiled water temperature T.

[0044] When the cooled boiled water equipment is turned on, the intelligent controller acquires the measured cooled boiled water temperature T3 detected by the cooled boiled water temperature probe at intervals t. It compares the measured cooled boiled water temperature T3 with the required cooled boiled water temperature T. If the difference between the measured cooled boiled water temperature T3 and the required cooled boiled water temperature T exceeds the difference range, the flow rate Q2 of room temperature water entering the heat exchanger is finely adjusted.

[0045] Furthermore, the flow rate Q2 of room temperature water entering the heat exchanger is based on the formula stored in the intelligent controller:

[0046] Q2 = Q1 * K * (T1 - T) / (T - T2) is determined, where K represents the heat transfer coefficient of the heat exchanger.

[0047] Furthermore, if the difference between the measured temperature of cooled boiled water T3 and the required temperature of cooled boiled water T exceeds the range of difference, the flow rate Q2 of room temperature water entering the heat exchanger will be adjusted to Q2-(T3-T)*N*Q2max / n, where Q2max is the maximum flow rate of the room temperature water outlet pump, and n indicates that Q2max is divided into n equal parts.

[0048] Specifically, the intelligent controller obtains the high-level hot water temperature T1 in the hot water tank 2 through the second hot water tank temperature probe 22, obtains the normal temperature water temperature T2 in the normal temperature water tank 1 through the normal temperature water tank temperature probe 11, and obtains the number of times the drain valve 40 is opened, N.

[0049] There is a matching relationship between the number of faucets opened (N) and the flow rate (Q1) of hot water entering the heat exchanger 3, and this matching relationship is stored in the intelligent controller. The flow rate (Q1) of hot water entering the heat exchanger 3 is the flow rate of the hot water outlet pump 321. Therefore, when the intelligent controller obtains the number of faucets opened (N), it retrieves the stored matching relationship and adjusts the flow rate of the hot water outlet pump 321 to match the number of faucets opened (N), thereby achieving a match between the total output of boiled water and the number of faucets opened. This solves the problem in the prior art where the output of boiled water decreases when more faucets are opened, ensuring that the flow rate of the drinking water equipment of this utility model is not too high when a single faucet is opened, and not too low when multiple faucets are opened.

[0050] For water cooling equipment, there is a relationship between the temperature and flow rate of the cooled boiled water. The control method of this invention takes into account both water temperature and flow rate regulation. Through a single control method, the temperature and flow rate of the cooled boiled water are adjusted simultaneously, ensuring that the cooled boiled water provided by the equipment meets both temperature and flow rate requirements. In this control method, the flow rate Q1 of hot water entering the heat exchanger is first matched with the number of faucets opened N. Based on the number of faucets opened N, the flow rate Q1 of hot water entering the heat exchanger is initially determined. With the initial flow rate Q1 of hot water entering the heat exchanger determined, the temperature of the cooled boiled water is intelligently adjusted. Specifically, based on the current state of the water dispenser, such as the water temperature T2 of the room temperature water tank, the water temperature T1 of the hot water tank, and the required cooled boiled water temperature T, the flow rate Q2 of room temperature water flowing into the heat exchanger 3 is calculated according to the formula stored in the intelligent controller. At the same time, during the operation of the water dispenser, the intelligent controller monitors the actual temperature of the cooled boiled water at intervals or in real time. When the difference between the actual water temperature T3 and the required water temperature T exceeds the difference range, the intelligent controller fine-tunes the flow rate Q2 of room temperature water flowing into the heat exchanger 3. By adjusting and fine-tuning the flow rate Q2 of room temperature water flowing into the heat exchanger 3, the temperature of the cooled boiled water can be more accurately adjusted, ensuring that the cooled boiled water produced by the water dispenser meets the required temperature.

[0051] Figure 2 shows the second embodiment of this utility model. In this second embodiment, the structure of the cooled boiled water drinking device is roughly the same as that of the preferred embodiment shown in Figure 1, except that the hot water tank 2 in the second embodiment is a closed water tank, also known as a pressurized water tank. It has a vent pipe 26 with a vent valve 260 on its top. The vent valve 260 is a mechanical structure and can only be used for venting, not for draining water. The closed water tank has a certain pressure inside, so there is no need to install a hot water pump on the second heat exchange channel 32 connected to the heat exchanger 3, thus simplifying the hot water outlet pipeline. Because the hot water tank 2 is a closed water tank, the outlet of the cooled boiled water circulation pipeline 6 leads to the outside of the drinking water device. When the cooled boiled water temperature in the cooled boiled water outlet pipeline 5 is lower than the required water temperature, the intelligent controller controls the circulation valve 60 to open, allowing the water in the cooled boiled water outlet pipeline to be directly discharged from the drinking water device through the cooled boiled water circulation pipeline 6, ensuring that the first cup of water the user receives from the tap is cooled boiled water at the required temperature.

[0052] Based on this second embodiment, the present invention proposes another method for intelligently adjusting the temperature and flow rate of cooled boiled water, which includes the following steps:

[0053] The user inputs the desired temperature T of cooled boiled water through the operating interface connected to the smart controller, and the smart controller stores the desired temperature T of cooled boiled water.

[0054] The intelligent controller obtains the hot water temperature T1 of the hot water tank, the ambient water temperature T2 of the ambient water tank, and the number of faucets opened N;

[0055] Based on the number N of faucets opened, the intelligent controller retrieves the stored hot water flow rate Q1 entering the heat exchanger to match the number N of faucets opened.

[0056] The flow rate Q1 of hot water entering the heat exchanger is determined based on the hot water temperature T1 in the hot water tank, the ambient water temperature T2 in the ambient water tank, and the required cooled boiled water temperature T.

[0057] Determine the flow rate Q3 of the hot water supply pump based on Q3 = Q1 - Q2;

[0058] When the cooled boiled water equipment is started, the intelligent controller acquires the measured cooled boiled water temperature T3 detected by the cooled boiled water temperature probe every t time interval. It compares the measured cooled boiled water temperature T3 with the required cooled boiled water temperature T. If the difference between the measured cooled boiled water temperature T3 and the required cooled boiled water temperature T exceeds the difference range, the flow rate Q2 of room temperature water entering the heat exchanger is finely adjusted, and the flow rate Q3 of the hot water replenishment pump is also finely adjusted.

[0059] Furthermore, the flow rate Q2 of room temperature water entering the heat exchanger is based on the formula stored in the intelligent controller:

[0060] Q2 = Q1 * K * (T1 - T) / (T - T2) is determined, where K represents the heat transfer coefficient of the heat exchanger.

[0061] Furthermore, if the difference between the measured cooled boiled water temperature T3 and the required cooled boiled water temperature T exceeds the range of difference, the flow rate Q2 of room temperature water entering the heat exchanger is adjusted to Q2-(T3-T)*N*Q2max / n, where Q2max is the maximum flow rate of the room temperature water outlet pump, and n indicates that Q2max is divided into n equal parts. Then, according to Q3=Q1-Q2, the flow rate Q3 of the hot water supply pump is further fine-tuned.

[0062] In this control method, the flow rate Q1 of hot water entering the heat exchanger is first matched with the number of faucets opened N. Based on the number of faucets opened N, the intelligent controller retrieves the stored flow rate Q1 of hot water entering the heat exchanger. With the flow rate Q1 of hot water entering the heat exchanger initially determined, the temperature of the cooled boiled water is intelligently adjusted. Specifically, based on the current state of the water dispenser, such as the temperature T2 of the room temperature water in the room temperature water tank, the temperature T1 of the hot water in the hot water tank, and the required cooled boiled water temperature T, the flow rate Q2 of room temperature water entering the heat exchanger and the flow rate Q3 of room temperature water replenishing the hot water tank 2 (i.e., the hot water replenishment pump) are calculated according to formulas stored in the intelligent controller. Simultaneously, during the operation of the water dispenser, the intelligent controller monitors the actual temperature of the cooled boiled water at intervals or in real time. When the difference between the actual water temperature and the required water temperature exceeds the specified range, the intelligent controller fine-tunes the flow rate Q2 of room temperature water entering the heat exchanger and the flow rate Q3 of the hot water replenishment pump. In this control method, Q2 and Q3 are fine-tuned while ensuring that Q2+Q3=Q1, so that the temperature of the boiled water can be adjusted more precisely, ensuring that the boiled water produced by the water supply equipment meets the required temperature.
