Description

Technical Field

[0001] The utility model relates to an instant heating type intelligent temperature control water channel structure. Background Art

[0002] At present, the temperature control technology of common instant water dispensers on the market generally controls the water outlet temperature by controlling the power of the heating plate and the water flow rate. When the heating plate starts to heat at room temperature, it will be preheated for a few seconds. After the temperature of the heating plate rises to a certain value, the water pump or solenoid valve will be started to heat the water while flowing through the heating plate. For example, if you want to produce 98-degree hot water, preheat the heating plate to 50 degrees before discharging water. At this time, the temperature of the water flowing out of the outlet will slowly rise from 50 degrees to 98 degrees. This process takes about 8-10 seconds, which causes the water temperature flowing into the cup to fail to reach the target temperature. For example, if 300ml of water is discharged, the average water temperature is only about 80 degrees, which seriously affects the user experience. If you want to achieve an average water temperature of more than 92 degrees, you must pour out the first cup of water and discharge the second cup of water while the heating plate is still in a hot state of more than 90 degrees, so that the average temperature of the hot water in the cup can reach more than 92 degrees. If you want to extend the preheating time and make the heating plate reach more than 80 degrees When water comes out again, it will cause splashing, because the preheating temperature is too high before water comes out. At the moment when the water pump or solenoid valve is turned on, the water temperature will reach 100 degrees and splash out. This is because the water in the heating plate is heated under static conditions. If the preheating temperature is too high, it will splash out at the moment the water is turned on. This phenomenon has been confirmed in countless experiments. This may scald the user and the user experience is also very poor. The existing instant water dispensers have fully reflected this defect. For the time being, there is no instant water dispenser whose first sip of water at room temperature can reach more than 95 degrees, and the highest water outlet temperature cannot reach 100 degrees, and it is difficult to avoid splashing. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes an instant intelligent temperature-controlled water channel structure, which can achieve high-temperature hot water output and solve the splashing problem.

[0004] The utility model proposes an instant heating type intelligent temperature control water circuit structure, which includes a first flow meter, a heating tube, a high-temperature water collecting chamber, a hot water temperature probe and a first pump body which are sequentially connected to a first water circuit, the output end of the first pump body is connected to the input end of the heating tube, the high-temperature water collecting chamber is provided with a steam exhaust port and a water outlet, the water outlet is connected to a hot water outlet pipe, the hot water outlet pipe is sequentially connected to an electromagnetic valve and a water outlet nozzle, the steam exhaust port is connected to a pressure relief valve, the first flow meter, the heating tube, the hot water temperature probe, the first pump body and the electromagnetic valve are all electrically connected to a controller.

[0005] In one or more embodiments, the water outlet nozzle is a steam-water separation nozzle, and the output end of the pressure relief valve is connected to the steam inlet of the steam-water separation nozzle.

[0006] In one or more embodiments, the first pump body is a high-temperature water pump.

[0007] In one or more embodiments, the input end of the first water circuit is connected to a pressure-stabilizing valve.

[0008] In one or more embodiments, the controller is a single chip microcomputer.

[0009] In one or more embodiments, the water circuit structure also includes a second water circuit, the water inlet end of the second water circuit is connected to the first water circuit, the second water circuit is connected to a second flow meter and a second pump body, the water outlet end of the second water circuit is connected to a hot water outlet pipe, the hot water outlet pipe is provided with a water outlet temperature probe located in the input end direction of the water outlet nozzle, the hot water outlet pipe is connected to a pressure regulating valve, the first water circuit is connected to a water inlet temperature probe, and the controller is electrically connected to the water inlet temperature probe, the water outlet temperature probe, the pressure regulating valve, the second flow meter and the second pump body.

[0010] The beneficial effects of the utility model are as follows: a high-temperature water collecting chamber is added to the water circuit structure, and hot water is circulated through the first pump body and input into the heating tube for heating to the target temperature. During the circulating heating process, since the water circuit is closed, the pressure in the high-temperature water collecting chamber is relatively high. Therefore, even if the water temperature reaches 100 degrees Celsius, boiling will not occur under high-pressure conditions. After the water outlet temperature is reached through circulation, hot water of sufficient temperature is directly output by opening the solenoid valve, thereby solving the splashing phenomenon and also preventing water waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic diagram of the waterway structure of the utility model. DETAILED DESCRIPTION

[0012] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0013] Please see attached Figure 1The utility model provides an instant heating intelligent temperature control water circuit structure, which includes a first water circuit and a second water circuit. The first water circuit is connected with a pressure regulating valve 12, a water inlet temperature probe 17, a first flow meter 1, a heating pipe 2, a high-temperature water collecting chamber 3, a hot water temperature probe 4 and a first pump body 5 in sequence. The output end of the first pump body is connected with the input end of the heating pipe 2. The high-temperature water collecting chamber 3 is provided with a steam exhaust port 6 and a water outlet 7. The water outlet is connected with a hot water outlet pipe 8. The hot water outlet pipe is connected with a solenoid valve 9, a pressure regulating valve 16 and a water outlet nozzle 10 in sequence. The steam exhaust port is connected with a pressure relief valve 11. The water inlet end of the second water circuit is connected with the first water circuit. The second water circuit is connected, and the connection is located between the water inlet temperature probe 17 and the first flow meter 1, the second flow meter 13 and the second pump body 14 are connected, the water outlet end of the second water circuit is connected to the hot water outlet pipe 8, specifically can be connected to the water outlet end of the pressure regulating valve, the hot water outlet pipe 10 is provided with a water outlet temperature probe 15 in the input end direction, the water inlet temperature probe 17, the first flow meter 1, the heating tube 2, the hot water temperature probe 4, the first pump body 5, the solenoid valve 9, the second flow meter 13, the second pump body 14, the pressure regulating valve 16, the water outlet temperature probe 15 are all electrically connected to the controller, preferably, the controller is a single chip microcomputer.

[0014] The specific working principle of the water circuit structure is that the first water circuit enters water, and the pressure regulating valve outputs the water pressure stably. The output pressure of the pressure regulating valve is specifically 1.5KG, and the pressure of the pressure relief valve is 2KG, so that the pressure of the first water circuit and the second water circuit is also maintained at about 1.5KG. When the water is started for the first time, the second pump body, the first pump body and the solenoid valve work simultaneously for several seconds. At the same time, the first flow meter and the second flow meter detect whether there is flow to determine whether there is water in the first water circuit and the second water circuit. If there is no water, the controller reports water shortage, indicating that the next step cannot be performed. If it is determined that there is flow, the next step can be performed.

[0015] At this time, select 100-degree water outlet, the first pump body and the heating tube are started at the same time, and the first water circuit performs internal circulation heating. Specifically, the solenoid valve is in a closed state, and the water in the first water circuit is output from the heating tube to the high-temperature water collecting chamber, the first pump body, and then enters the heating tube to achieve circulation heating. When the hot water temperature probe detects that the temperature reaches the preset value, the solenoid valve opens and hot water is output from the water outlet. In order to continuously and stably output hot water at the target temperature, the controller obtains the water inlet temperature through the water inlet temperature probe, obtains the water flow through the first flow meter, controls the power of the heating tube, and controls the output flow of the pressure regulating valve, thereby controlling the water flow entering the heating tube and the output water flow to achieve continuous and stable output of the target outlet water temperature. In this way, the water can reach a temperature of more than 95 degrees as soon as it comes out, and can even reach a water outlet temperature of 100 degrees, and there will be no splashing, because the pressure in the high-temperature water collection chamber reaches more than 1.5KG, so even if the water temperature reaches 100 degrees, it will not boil, and the water will gather at the bottom of the high-temperature water collection chamber, and the water vapor will rise to the top of the high-temperature water collection chamber. Even if the temperature is high, only water will come out without water vapor, thereby ensuring the temperature and stability of the water outlet, and there will be no splashing to scald the user. This method can be used to heat water from room temperature to hot water of different temperatures, ensuring that the first mouthful of hot water reaches the target temperature, and there will be no phenomenon of heating while the water is being discharged, which lowers the average water temperature in the cup. In addition, there is a steam exhaust port on the upper part of the high-temperature water collecting chamber, which is connected in series with a pressure relief valve and then discharged to the steam-water separation nozzle and connected to the atmosphere. In this way, if the solenoid valve cannot be opened or the temperature control fails, causing the pressure in the high-temperature water collecting chamber to be greater than the pressure of the pressure relief valve, the pressure relief valve will automatically open to release the pressure of the first water channel, ensuring the safety of the equipment and preventing explosion.

[0016] In addition, if you want to produce normal temperature water after producing high-temperature hot water, you only need to open the second pump body to bypass the high-temperature heating tube and directly produce normal temperature water.

[0017] If you want to produce 40-degree warm water after producing high-temperature hot water, you should first open the second pump body, solenoid valve and pressure regulating valve. The second pump body and pressure regulating valve are calculated by the single-chip microcomputer according to the hot water temperature and the normal temperature water temperature to calculate the best flow ratio, and then control the voltage of the second pump body and the rotation of the pressure regulating valve to make the flow of the first flow meter and the second flow meter reach the best ratio, so that the hot water and normal temperature water are mixed together in the best ratio to produce water, so that the outlet water temperature reaches 40 degrees as soon as possible. In addition, the outlet water temperature probe will monitor in real time whether the outlet water temperature reaches 40 degrees, so as to further control the rotation of the second pump body and the pressure regulating valve to make the outlet water temperature more accurate. The same principle, after producing high-temperature water and other low-temperature water, you can use this method to blend the ratio of hot water and normal temperature water, so that the target outlet water temperature can be achieved as soon as the water is produced. In this way, no matter what temperature of water has been produced, the next gear will produce a lower temperature of water, and the target temperature can be achieved as soon as the water is produced, and the water will not be discharged while cooling, so that the water temperature in the water cup is higher than the target value.

[0018] The water outlet nozzle 10 is a steam-water separation nozzle, and the output end of the pressure relief valve 11 is connected to the steam inlet of the steam-water separation nozzle. When high pressure appears in the high-temperature water collecting chamber, the pressure is directly released through the steam-water separation nozzle to ensure the safety of the waterway and equipment.

[0019] Since the first water circuit needs to circulate hot water to reach the target water outlet temperature, a high temperature water pump is preferably used for the first pump body 5. The heating tube in this solution can be a thick film heating tube, a nano film heating tube, a quartz glass heating tube, a traditional tungsten wire heating tube, etc.
