Inside component 3.

In these embodiments, the liquid treatment device further includes a liquid inlet assembly 1 and a liquid outlet assembly 3. The liquid inlet assembly 1 is used to connect to a water source for supplying water to the heat exchange device 4 or the heating channel, and the liquid outlet assembly 3 It is used to discharge the water at the outlet of the heat exchange device 4. This kind of liquid treatment device is provided with independent liquid inlet assembly 1, heat exchange device 4 and liquid outlet assembly 3, which makes each part of the entire product relatively simple, thus making the product easier to process. Of course, in another solution, the liquid inlet assembly 1 and the liquid outlet assembly 3 may not be separately provided. In this case, the liquid inlet channel, the liquid outlet channel 32, the heating assembly 2 and the heat exchange device 4 can be combined into one water collection unit. , Heating, heat exchange and water outlet as an integral part. Of course, in another solution, the heat exchange device 4, the liquid outlet channel 32 and the liquid inlet channel can also be integrated, and the heating assembly 2 can be an independent part. Of course, the heating assembly 2 and the liquid inlet channel can also be integrated. At this time, the heat exchange device 4 and the liquid outlet channel 32 can be integrated or can be separate parts.

In some embodiments, a heating channel is provided in the heating assembly 2, and when the heating channel is connected between the liquid inlet channel and the heat exchange device 4, the heating assembly 2 and the liquid inlet assembly 1 have a separate structure, and the heating assembly 2 and the heat exchange device The device 4 has a split structure; when the heating assembly 2 is set corresponding to the liquid inlet assembly 1, the heating assembly 2 is set in the liquid inlet channel; when the heating assembly 2 is set corresponding to the heat exchange device 4, the heating assembly 2 is set in the heat exchange device 4.

In these embodiments, the heating assembly 2 may be configured to include a heating channel, and the heating assembly 2 can be connected between the liquid inlet channel and the heat exchange device 4, so that the heat exchange device 4 can pass through the heating channel and the inlet The liquid channel is connected. At this time, the water entering from the liquid inlet channel can first enter the heating channel, and enter the heat exchange device 4 after being heated in the heating channel, and flow out from the liquid outlet channel 32 after passing through the heat exchange device 4 . At this time, the heating assembly 2 and the heat exchange device 4 and the liquid inlet device may be of a separate structure, that is, the heating assembly 2 may be a structure independent of the heat exchange device 4 and the liquid inlet device. Of course, in another solution, The heating assembly 2 and the heat exchange device 4 and the liquid inlet device may also be an integrated structure, such as an integrated structure or an integrated structure formed by processing. In addition, in another solution, the heating element 2 can also be directly arranged in the heat exchange device 4. At this time, the heating of the liquid can be directly realized in the heat exchange device 4. When it is hot, the heating element 2 can also be directly arranged in the heat exchange device 4. In the liquid inlet channel, so as to be able to directly realize the heating of the liquid in the liquid inlet channel. When the heating assembly 2 is arranged in the heat exchange device 4 or the liquid inlet channel, the heating assembly 2 and the heat exchange device 4 or the liquid inlet channel may be an integrated structure or a separate structure.

Among them, a heat exchange channel can be provided in the heat exchange device 4 so that the liquid entering the heat exchange channel can be transferred to the liquid outlet channel 32 after heat exchange. Of course, a non-heat exchange channel can also be provided in the heat exchange device 4 At this time, the liquid entering the non-heat exchange channel can be directly transported to the liquid outlet channel 32 without being cooled. That is, here, the heat exchange device 4 has the function of exchanging heat to cool the water, but this does not mean that the liquid entering the heat exchange device 4 must undergo heat exchange before being transported to the liquid outlet channel 32, that is, passing through the heat exchange device. The liquid in 4 can also flow out directly without heat exchange.

In some embodiments, as shown in FIGS. 8 and 9, the heat exchange device 4 includes a first heat exchange channel 40 and a second heat exchange channel 42, and the second heat exchange channel 42 is in communication with the liquid inlet channel and the liquid outlet channel 32. , The first heat exchange channel 40 can exchange heat with the second heat exchange channel 42 to cool the liquid in the second heat exchange channel 42.

In these embodiments, the heat exchange device 4 has the first heat exchange channel 40 and the second heat exchange channel 42 built-in, and at the same time, the second heat exchange channel 42 can be connected to the liquid inlet channel and the liquid outlet channel 32 and guided In this way, the liquid such as water heated by the heating assembly 2 can exchange heat with the first heat exchange channel 40 in the second heat exchange channel 42 and then be discharged through the liquid outlet assembly 3 after cooling. When the high-temperature liquid heated by the heating element 2 flows through the second heat exchange channel 42, its temperature is higher than the temperature of the coolant in the first heat exchange channel 40, so that the first heat exchange channel 40 can continuously absorb the first heat exchange channel 40. The heat of the liquid such as water in the second heat exchange channel 42 to realize the heat exchange between the first heat exchange channel 40 and the second heat exchange channel 42, so that it can pass through the first heat exchange channel 40 and the second heat exchange channel The heat exchange between 42 realizes cooling of liquid such as water in the second heat exchange channel 42. However, this structure can use the principle of heat exchange to cool liquids such as water heated by the heating device. This cooling method has a simple structure and is easy to implement, thereby simplifying the structure of the product and reducing the cost of the product. Of course, other cooling methods can also be used to achieve cooling, such as installing a fan to perform air cooling. In this case, the heat exchange device 4 may also be an air cooling device or the like.

Further, when a heating channel is provided in the heating assembly 2, the second heat exchange channel 42 communicates with the liquid inlet channel through the heating channel, and when the heating assembly 2 is arranged in the heat exchange channel, the heating assembly 2 is arranged in the second heat exchange channel 42 Inside.

In this embodiment, when a heating channel is provided in the heating assembly 2, the second heat exchange channel 42 can be connected to the liquid inlet channel through the heating channel, so that liquids such as water can enter through the liquid inlet channel and the heating channel in turn. In the second heat exchange channel 42, when the heating element 2 is arranged in the heat exchange device 4, the heating element 2 can be arranged in the second heat exchange channel 42 to directly heat the water in the second heat exchange channel 42. At this time, the first half of the second heat exchange channel 42 can be used for heating, and the second half can be used for heat exchange and cooling of liquids such as water.

In some embodiments, the inlet of the first heat exchange channel 40 communicates with the liquid inlet channel; when the second heat exchange channel 42 communicates with the liquid inlet channel through the heating channel, the outlet of the first heat exchange channel 40 communicates with the inlet of the heating channel , Or communicate with the inlet channel.

In these embodiments, the first heat exchange channel 40 can connect the inlet of the liquid inlet channel and the heating channel on the one hand, and the outlet of the heating channel is connected to the second heat exchange channel 42. Therefore, the liquid inlet channel in the present application- The first heat exchange channel 40-the heating channel and the second heat exchange channel 42 are connected end to end in turn, so that the water and other liquids entering from the liquid inlet channel first pass through the first heat exchange channel 40 of the heat exchange device 4, and then from the first heat exchange channel The channel 40 enters the heating channel, then enters the second heat exchange channel 42 from the heating channel, and after the second heat exchange channel 42 exchanges heat with the first heat exchange channel 40, it flows out from the outlet of the liquid outlet channel 32. With this arrangement, the low-temperature liquid entering the liquid inlet channel, that is, the liquid that is not heated, can be used to cool the liquid that enters the second heat exchange channel 42 after heating, so there is no need to provide additional cooling liquid, and also There is no need to separately set up a cooling circulation circuit, but only a reasonable arrangement of the liquid flow path structure inside the product, so that the cooling cost can be reduced. In addition, after the first heat exchange channel 40 and the second heat exchange channel 42 exchange heat, the liquid in the first heat exchange channel 40 will increase in temperature due to absorbing the heat of the liquid such as water in the second heat exchange channel 42 , And the cooling liquid after the temperature rises will directly enter the heating channel for heating, so that when it is heated in the heating channel, the heat required to heat it to boiling can be reduced. That is to say, this structure can not only use the water before heating to cool the heated water and other liquids, but also can directly transport the cooling liquid after absorbing heat to the heating channel to be heated to the water required by the user, which can achieve heating After making full use of the excess heat in the water, the heat utilization rate of the product can be improved.

In another solution, after the inlet of the first heat exchange channel 40 communicates with the liquid inlet channel, the outlet of the first heat exchange channel 40 may not communicate with the inlet of the heating channel, but directly communicate with the liquid inlet channel. After the liquid entering the first heat exchange channel 40 from the liquid inlet channel exchanges heat with the second heat exchange channel 42, it passes through the first heat exchange channel 40 and returns to the liquid inlet channel so as to be able to heat the liquid in the liquid inlet channel. In this way, the temperature of the liquid entering the heating channel can be increased, and the heat in the first heat exchange channel 40 can be recovered and utilized. In a possible embodiment, the liquid storage tank 44 can be connected to the liquid inlet channel, so that the liquid in the liquid inlet channel can first enter the liquid storage tank 44, and then the inlet of the first heat exchange channel 40 can be The outlet is connected to the liquid storage tank 44, and the inlet of the heating channel is also connected to the liquid storage tank 44, so that the liquid storage tank 44 can form a refrigeration cycle with the first heat exchange channel 40 to realize the second heat exchange channel. The cooling of 42, on the other hand, also enables the liquid storage tank 44 to use the hot water absorbed by the first heat exchange channel 40 to heat the liquid to enter the heating channel, so as to realize the reuse of heat.

In some embodiments, as shown in FIGS. 6 and 7, the heat exchange device 4 further includes: a liquid storage tank 44 connected to the inlet of the first heat exchange channel 40 and the outlet of the first heat exchange channel 40 to form a cooling circulation loop .

In these embodiments, a liquid storage tank 44 may be additionally provided, and the liquid storage tank 44 forms a loop with the first heat exchange channel 40, so as to continuously provide cold energy to realize the control of the water in the liquid outlet channel 32. Wait for the liquid to cool down. With this structure, the cooling circuit can be separated from the liquid flow path formed by the liquid inlet assembly 1, the heating module 2 and the liquid outlet assembly 3, so that the cooling circuit and the liquid flow path can work independently, thereby enabling cooling The circulation loop can be opened or closed separately, so that when the liquid treatment device is working, it can be determined whether to open the cooling loop according to actual needs, and when the cooling loop is not opened, the heated water can directly discharge the hot water of the corresponding temperature , Such as boiling water, and when the cooling cycle is turned on, the water can be heated to a higher temperature such as boiling, and then cooled to a lower temperature before being discharged. This structure enables the product to not only directly discharge the water after heating, but also to discharge the water after heating and then cooling it. This can expand the function of the product and realize the diversification of the product, so that the product can better meet the needs of users. Multiple needs.

In some embodiments, as shown in FIGS. 6 and 7, when a heating channel is provided in the heating assembly 2, the liquid storage tank 44 communicates with the liquid inlet channel, and the heating channel is directly connected to the liquid inlet channel, or the inlet of the heating channel is connected to the inlet of the heating channel. The liquid storage tank 44 is connected to connect with the liquid inlet channel through the liquid storage tank 44.

In these embodiments, a heating channel is provided in the heating assembly 2, and the heating channel is connected between the liquid inlet channel and the heat exchange device 4, so that when the heat exchange device 4 communicates with the liquid inlet channel through the heating channel, The liquid storage tank 44 is connected between the inlet of the heating channel and the liquid inlet channel, so that on the one hand, the liquid inlet assembly 1 can be used to add cooling liquid into the liquid storage tank 44, and on the other hand, the first heat exchange channel 40 and the first heat exchange channel 40 can be The heat exchanged by the second heat exchange channel 42 can also flow back into the liquid storage tank 44 through the first heat exchange channel 40, and then heat the liquid in the liquid storage tank 44, and since the heating channel is also connected to the liquid storage tank 44, In this way, the heat after the cooling and heat exchange can be used in the liquid storage tank 44 to heat the water liquid entering the heating channel in advance, so that the heat generated by the heat exchange can be fully utilized. In another solution, the heating channel and the liquid storage tank 44 can also be directly connected to the liquid inlet channel at the same time, so that water can be supplied to the liquid storage tank 44 and the heating channel simultaneously through the liquid inlet channel.

Wherein, since the first heat exchange channel 40 and the second heat exchange channel 42 exchange heat, the water discharged after heating by the heating assembly 2 can interact with the water in the first heat exchange channel 40 during the process of flowing through the second heat exchange channel 42 The material exchanges heat, so that the water heated by the heating assembly 2 can be effectively cooled before being discharged along the liquid outlet 34, so that the liquid heating appliance can provide water at different temperature gears to meet the user's water outlet requirements at different temperatures. In addition, in this structure, the heating element 2 can heat the water to a certain temperature to remove most of the bacteria in the water and meet the food safety requirements. Compared with the related technology that heats water to a specified temperature in the non-boiling gear to provide multi-range temperature water output, it can meet the water temperature needs of users at different temperature gears, while the sterilization effect is more guaranteed, and the user can be taken into consideration. Water outlet temperature requirements and food safety requirements, and the heat-exchanged and heated water in the first heat exchange channel 40 of the heat exchange box 10 can be used to enter the heating assembly 2 to realize the heat recovery of the product and improve the operating energy efficiency of the product.

In this way, the temperature control adjustment of the waterway system can be formed, which can improve the stability and accuracy of the product water outlet temperature, so that the actual water outlet temperature of the product can better meet the water outlet temperature requirements, and the product use experience can be improved.

In some embodiments, as shown in FIG. 73, the temperature measurement system 70 includes a first temperature measurement element 710, and the first temperature measurement element 710 collects the temperature at the water inlet 331 and sends a corresponding signal to respond according to the collection result; The control component 222 is connected to the first temperature measuring element 710. The control component 222 controls the heating power of the heating component 2 and/or the liquid flow parameters (such as flow rate, flow rate) at the water inlet 331 at least according to the signal from the first temperature measuring element 710. Wait). Among them, because the heating element 2 may absorb water from the first heat exchange channel 40 after heat exchange, the temperature is relatively high and changes in real time. The first temperature measuring element 710 is set to collect the water inlet 331 of the heating element 2 According to this, the heating power of the heating component 2 and/or the liquid flow parameters (such as flow rate, flow velocity, etc.) at the water inlet 331 can be controlled. In this way, the heat supply of the heating component 2 and the heating energy demand can be The compatibility is better, and the sterilization effect of the heating element 2 on the liquid is better ensured. For example, it is better to ensure that the water in the heating element 2 is heated to boiling, which improves the food safety and makes the heat exchange box 10 The thermal efficiency is more accurate, so that the temperature of the outlet water at the outlet nozzle 34 is accurate and stable.

For example, the first temperature measuring element 710 is arranged at the water inlet 331 of the heating assembly 2 and partially penetrates into the water inlet 331 to collect the water temperature in the water inlet 331, or is located outside the water inlet 331 through the water inlet 331. The pipe temperature reflects the water temperature in the water inlet 331 based on the pipe temperature of the water inlet 331. In this way, by controlling the heating power of the heating assembly 2 and/or the liquid flow parameters at the water inlet 331 based on the water temperature of the water inlet 331, more accurate temperature control can be achieved, so as to better realize the accurate water outlet temperature at the liquid outlet 34 And stability.

For example, a pump (which can be understood with reference to the second pump 214 in FIG. 77) or a valve may be provided upstream of the heating component 2 in the waterway system 30. Specifically, for example, a pump or valve may be connected to the water inlet 331. , Or centrally connect the pump or valve with the water inlet 331 via a pipe. The control component 222 controls the liquid flow parameters such as the flow rate and flow rate at the water inlet 331 by adjusting the working parameters of the pump (such as flow, speed, frequency, etc.) or the opening of the valve, and by setting the pump or valve at the water inlet 331 In the upstream position, in this way, the high-temperature water heated by the heating element 2 will not pass through the pump or valve, thereby better guaranteeing the service life of the pump or valve. Of course, in other embodiments, a pump or valve can also be arranged on the downstream side of the heating assembly 2 in the waterway system 30 according to requirements, which can also achieve the purpose of adjusting liquid flow parameters such as the flow rate and flow rate at the water inlet 331.

In some embodiments, as shown in FIG. 73, the temperature measurement system 70 includes a second temperature measurement element 720, and the second temperature measurement element 720 collects the temperature at the drain 332 and sends a corresponding signal to respond according to the collection result; The control component 222 is connected to the second temperature measuring element 720. The control component 222 controls the heating power of the heating component 2 and/or the liquid flow parameters (such as flow rate, flow rate) at the water inlet 331 at least according to the signal from the second temperature measuring element 720. Wait). Among them, because the heating assembly 2 may absorb water from the first heat exchange channel 40 after heat exchange, the temperature is relatively high and changes in real time, and the second temperature measuring element 720 is set to collect the water from the drain 332 of the heating assembly 2 Water temperature, and control the heating power of the heating component 2 and/or the liquid flow parameters (such as flow rate, flow rate, etc.) at the water inlet 331 accordingly. In this way, the heat supply of the heating component 2 can be compared with the heating energy demand. The adaptability is better, and the sterilization effect of the heating element 2 on the liquid is better ensured. For example, it is better to ensure that the water in the heating element 2 is heated to boiling, which improves the safety of food and enables the heat exchange in the heat exchange box 10 The efficiency is more accurate, so that the temperature of the outlet water at the outlet nozzle 34 is accurate and stable.

For example, the second temperature measuring element 720 is arranged at the drain port 332 of the heating assembly 2 and partially penetrates into the drain port 332 to collect the water temperature in the drain port 332, or is located outside the drain port 332 through the collection drain port 332 The pipe temperature reflects the water temperature in the water outlet 332 based on the pipe temperature of the water outlet 332. In this way, by controlling the heating power of the heating assembly 2 and/or the liquid flow parameters at the water inlet 331 based on the water temperature of the water outlet 332, more accurate temperature control can be achieved, so as to better realize the accurate water outlet temperature at the liquid outlet 34 And stability.

Further, as shown in FIG. 74, the control component 222 is provided with a first comparator 510, and one input end of the first comparator 510 is connected to the output end of the second temperature measuring element 720 to obtain the temperature at the drain 332, The other input terminal of the first comparator 510 is connected to the preset temperature threshold, the temperature at the drain 332 does not exceed the preset temperature threshold, and the output signal of the first comparator 510 is configured to increase the heating power and the heating power of the heating assembly 2 /Or reduce the flow rate at the water inlet 331.

Specifically, for example, when the temperature at the water outlet 332 is lower than or equal to a preset temperature threshold, the first comparator 510 sends a signal to trigger the heating power of the heating assembly 2 to increase and/or trigger the flow parameter regulator 320 to reduce the flow rate of the water inlet 331, The temperature of the liquid discharged from the heating assembly 2 is increased accordingly, which better meets the sterilization requirements and enhances food safety; when the temperature at the drain 332 is higher than the preset temperature threshold, the first comparator 510 does not output a signal to make The heating power of the heating component 2 is maintained at the present and/or the flow rate of the water inlet 331 is maintained at the present. Of course, when the temperature at the drain 332 is higher than the preset temperature threshold, the output signal of the first comparator 510 can also be designed to trigger The heating power of the heating assembly 2 is reduced and/or the flow parameter adjustment member 320 is triggered to increase the flow rate of the water inlet 331.

Among them, the preset temperature threshold is 90°C to 100°C. Furthermore, for products suitable for use at an altitude of less than 1000 meters, the preset temperature threshold is further set to 95°C to 100°C. This can make the sterilization effect of the product more secure.

It can be understood that the preset temperature threshold may be the boiling temperature of the liquid to be heated (such as water), or may be slightly lower than the boiling temperature. It is understandable that the specific value of the preset temperature threshold in this solution is not limited by the above-exemplified 90℃～100℃ and 95℃～100℃. In fact, those skilled in the art can according to specific sterilization requirements. The specific numerical value of the preset temperature threshold can be flexibly adjusted, which will not be illustrated one by one here, but it belongs to the protection scope of this solution without departing from the design concept.

Further, as shown in FIG. 75, the control component 222 is provided with a second comparator 520, and one input end of the second comparator 520 is connected to the output end of the second temperature measuring element 720 to obtain the temperature at the drain 332, The other input of the second comparator 520 is connected to the boiling temperature, the temperature at the drain 332 is at least the boiling temperature, and the output signal of the second comparator 520 is configured to reduce the heating power of the heating element 2 and/or increase the input The flow rate at the nozzle 331.

Specifically, for example, when the temperature at the water outlet 332 is at the boiling temperature (for example, 100°C) and above for a long time, the second comparator 520 sends a signal to trigger the heating power of the heating assembly 2 to decrease and/or to trigger the flow parameter adjustment member 320 to increase. The flow rate of the water inlet 331 meets the need for sterilization while also achieving product energy saving and emission reduction; when the temperature at the water outlet 332 is lower than the boiling temperature, the second comparator 520 does not output a signal so that the heating power of the heating element 2 is maintained at The current and/or keep the flow rate of the water inlet 331 at the current. Of course, when the temperature at the water outlet 332 is lower than the boiling temperature, the output signal of the second comparator 520 can also be designed to trigger the heating power of the heating element 2 to increase and/ Or trigger the flow parameter regulator 320 to reduce the flow rate of the water inlet 331.

For example, the boiling temperature is 90°C to 100°C. This can make the sterilization effect of the product more secure. It is understandable that the specific value of the boiling temperature in this solution is not limited by the above-exemplified 90°C to 100°C. In fact, those skilled in the art can determine the above-mentioned boiling temperature according to the ambient pressure and specific boiling temperature requirements. The specific numerical value of the boiling temperature can be adjusted flexibly, which will not be illustrated one by one here, but it belongs to the protection scope of this scheme without departing from the design concept.

In some embodiments, as shown in FIG. 73, the temperature measurement system 70 includes a third temperature measurement element 730. The third temperature measurement element 730 collects the temperature at the liquid nozzle 34 and sends out a corresponding signal to respond according to the collected result. The control component 222 is connected to the third temperature measuring element 730, and the control component 222 controls the liquid flow parameters (such as flow rate, flow velocity, etc.) in the first heat exchange channel 40 at least according to the signal from the third temperature measuring element 730. The feedback adjustment has higher response timeliness, and can realize the rapid adjustment of the water temperature of the liquid outlet 34 to the target value, so that the water outlet temperature of the product is more accurate and stable.

For example, the third temperature measuring element 730 is disposed at the liquid outlet 34 and partially penetrates into the liquid outlet 34 to collect the water temperature in the liquid outlet 34, or is located outside the liquid outlet 34 and passes through the liquid collecting nozzle 34. The tube temperature reflects the water temperature in the liquid nozzle 34 based on the tube temperature of the liquid nozzle 34. In this way, by controlling the liquid flow parameters in the first heat exchange channel 40 based on the water temperature of the liquid outlet nozzle 34, more accurate temperature control can be achieved, thereby better realizing the accuracy and stability of the outlet water temperature at the liquid outlet nozzle 34.

Further, the liquid heating appliance further includes an instruction receiving element configured to obtain a target temperature instruction or a target gear instruction; the control component 222 is connected to the instruction receiving element, and the control component 222 is at least based on the liquid outlet from the third temperature measuring element 730 The temperature at 34 and the target temperature command or target gear command from the command receiving element control the flow rate in the first heat exchange passage 40.

For example, when the temperature at the liquid outlet 34 is lower than the temperature indicated by the target water temperature command or the target gear command, the flow rate in the first heat exchange passage 40 is reduced, so that the temperature drop rate in the second heat exchange passage 42 Correspondingly, the temperature at the liquid outlet 34 can quickly rise to the temperature indicated by the target water temperature command or the target gear command. When the temperature at the liquid outlet 34 is higher than the temperature indicated by the target water temperature command or the target gear command, the flow rate in the first heat exchange passage 40 is increased, so that the temperature drop rate in the second heat exchange passage 42 increases accordingly Large, the temperature at the liquid outlet 34 can quickly drop to the temperature indicated by the target water temperature command or the target gear command. The feedback adjustment has higher response timeliness and accuracy, and can quickly adjust the water temperature of the liquid outlet 34 to the target value, so that the water outlet temperature of the product is more accurate and stable.

It is connected to the first heat exchange passage 40, or a pump or valve is centrally connected to the first heat exchange passage 40 via a pipe; specifically, for example, a pump or valve is set in series with the first heat exchange passage 40, or a valve is set to connect to the first heat exchange passage 40. The heat passage 40 is arranged in parallel to form a bypass adjustment of the flow or flow velocity of the first heat exchange passage 40. In this way, the control component 222 controls the flow rate at the first heat exchange passage 40 by adjusting the working parameters of the pump (such as flow, speed, frequency, etc.) or the opening of the valve, so that the control component 222 can control the first heat exchange passage 40. The purpose of flow rate adjustment.

In some embodiments, the temperature measurement system 70 includes a fourth temperature measurement element 740, and the fourth temperature measurement element 740 collects the inlet water temperature of the first heat exchange channel 40, and sends a corresponding signal to respond according to the collected result; the control component 222 is connected to the fourth temperature measuring element 740, and the control component 222 controls the flow parameters of the first heat exchange channel 40 at least according to the signal from the fourth temperature measuring element 740.

For example, the fourth temperature measuring element 740 is arranged at the water inlet end of the first heat exchange channel 40, and partially penetrates into the first heat exchange channel 40 to collect the water temperature in the first heat exchange channel 40, or is located in the first heat exchange channel 40. A heat exchange channel 40 collects the tube temperature of the first heat exchange channel 40 to reflect the water temperature in the first heat exchange channel 40 based on the tube temperature of the first heat exchange channel 40. In this way, by controlling the liquid flow parameters (such as flow rate, flow velocity, fluid temperature, etc.) in the first heat exchange channel 40 based on the water temperature of the first heat exchange channel 40, more accurate temperature control can be achieved, thereby better achieving liquid flow. The temperature of the outlet water at the mouth 34 is accurate and stable.

For example, according to the temperature at the drain 332 of the heating assembly 2 and the target water temperature command or target gear command, the heat exchange load of the heat exchange box 10 can be calculated. This solution collects the inlet water temperature of the first heat exchange channel 40 , And adjust the flow rate, flow rate, fluid temperature and other parameters in the first heat exchange channel 40 according to the inlet water temperature of the first heat exchange channel 40, so that the heat exchange capacity of the heat exchange box 10 can be controlled correspondingly to reach the required heat exchange load. Therefore, the temperature of the outlet nozzle 34 can be controlled to meet the target water temperature command or the target gear command requirement, and the temperature of the outlet nozzle 34 can be maintained with good stability. This is also conducive to maintaining the energy-efficient operation of the heat exchange box 10, thereby improving the product Energy efficiency.

For example, under a certain heat exchange load, when the temperature of the inlet water collected in the first heat exchange channel 40 is low, the flow rate or flow velocity in the first heat exchange channel 40 can be controlled to decrease, so that the heat exchange supply The compatibility between the situation and the heat exchange load is better, so that the temperature of the liquid outlet 34 can be controlled to meet the needs of customers, and the temperature of the liquid outlet 34 can be stabilized. Under a certain heat exchange load, when the temperature of the inlet water collected in the first heat exchange channel 40 is too high, the flow rate in the first heat exchange channel 40 can be controlled to increase or the flow velocity increases, or the first heat exchange channel 40 can be switched. In order to reduce the inlet water temperature of the first heat exchange channel 40, the heat exchange supply amount and the heat exchange load are better compatible, and the temperature of the outlet nozzle 34 can be controlled to meet customer needs. The temperature of the liquid outlet 34 is stabilized. And through this design, the inlet temperature, flow, flow rate, etc. of the first heat exchange channel 40 can be better adapted to the heat exchange load, so that the first heat exchange channel 40 and the second heat exchange channel 42 can be Maintaining efficient heat exchange, in this way, to a certain extent, save the driving force requirements of the product, realize product energy saving and emission reduction, and also reduce the first heat exchange channel 40 and the second heat exchange channel 42 to a certain extent.

It is more accurate, and can predict the outlet water temperature at the liquid nozzle 34 more accurately, so that the actual outlet water temperature better meets the user's target demand temperature.

For example, when the target outlet water temperature is higher than the ambient temperature and the temperature difference is large, the outlet water temperature can be slightly increased in consideration of the accuracy of the outlet water temperature caused by the temperature difference. For example, the outlet water temperature can be increased by 0.1°C to 1°C, making the user practical The temperature difference between the temperature of the hot water received and the target outlet temperature is smaller.

For another example, when the ambient temperature is low, the heat dissipation during the process from the water outlet 332 of the heating assembly 2 to the liquid outlet 34 can be predicted based on the ambient temperature, so as to more accurately predict the heat transfer load of the heat exchange box 10 , The heat exchange box 10 can more accurately radiate and cool the hot water.

Wherein, between the first chamber and the second chamber, a conduction can be formed from the first chamber to the second chamber, for example, through a one-way valve or a through hole/channel with a certain height. This not only realizes that the liquid supply tank 5 can supply water to the heating assembly 2, but also realizes the connection between the first heat exchange channel 40 and the heating assembly 2 (that is, the connection between the first heat exchange channel 40 and the heating assembly 2 via the water distribution box 212 The realized central connection), so that the water discharged from the first heat exchange channel 40 can enter the heating assembly 2 to be heated, thereby realizing heat recovery and improving the energy saving of the product; in addition, between the first chamber and the second chamber, the The second chamber is cut off to the first chamber, so that the hot water in the second chamber will not return to the first chamber, which reduces the heat loss of the product and improves the energy-saving performance of the product.

In a working condition of the product, the water provided by the liquid supply tank 5 enters the first chamber, and the first pump 213 works to drive the water in the first chamber to enter the first heat exchange channel 40, and from the first heat exchange channel 40 After being discharged, return to the second chamber of the water distribution box 212. The second pump 214 works to drive the water in the second chamber to enter the heating assembly 2. Wherein, since the conduction can be formed from the first chamber to the second chamber, the water input into the heating assembly 2 from the second chamber may be the water provided by the liquid supply tank 5, or may be the first heat exchange channel 40 The discharged water may also be a collection of the water provided by the liquid supply tank 5 and the water discharged from the first heat exchange channel 40.

In some embodiments, the first temperature measurement element 710, the second temperature measurement element 720, the third temperature measurement element 730, the fourth temperature measurement element 740, and the fifth temperature measurement element 80 are temperature sensors. For example, the first temperature measurement element 710, the second temperature measurement element 720, the third temperature measurement element 730, the fourth temperature measurement element 740, and the fifth temperature measurement element 80 are one of a thermistor temperature sensor and a thermocouple temperature sensor. Or a combination of multiple.

Specific embodiment:

As shown in FIGS. 68 to 77, this embodiment provides a liquid heating appliance, such as a hot water bottle (bottle). That is, a waterway system 30 is formed in the hot water bottle (bottle), and a temperature measurement system 70 is connected to the waterway system 30. The temperature measurement system 70 is used to sense the temperature of the water in the waterway system 30 in real time and enable the chip (that is, the control component 222, It can also be referred to as a control panel) to control the heating power of the heating assembly 2 or the flow rate of the water pump (that is, the flow parameter adjustment member 320) to achieve the effect of controlling the water temperature.

More specifically, the hot water bottle (bottle) is more specifically an instant hot water bottle with a cooling module (ie, the heat exchange box 10). That is, the kettle (bottle) also has a heating component 2, a water pump, a liquid supply tank 5 suitable for storing water, a circuit board component (such as a power supply component 221 and a control board), a water delivery pipe and a water outlet pipe that can quickly heat water. The water delivery pipeline is arranged on the upstream side of the heating assembly 2, and the water outlet pipeline is arranged on the downstream side of the heating assembly 2. A cooling module (namely, the heat exchange box 10) is connected in series on the water outlet pipeline. A plurality of temperature measuring elements are also provided on the waterway system 30.

More specifically, as shown in Figure 77, the heating assembly 2 has a heating chamber 333, a water inlet 331 for the heating chamber 333 to enter water, and a drain 332 for the heating chamber 333 to drain water. The heating chamber 333 is provided with a heating element 334 to control The component 222 is connected to the heating element 334 and controls the power of the heating element 334 to adjust the heating power of the heating element 2. Wherein, the water inlet 331 is provided with a first temperature measuring element 710, and the drain 332 is provided with a second temperature measuring element 720. The first temperature measuring element 710 collects the inlet water temperature t1 of the heating assembly 2, and the second temperature measuring element 720 Collect the outlet water temperature t2 of the heating assembly 2.

As shown in FIG. 71 and FIG. 77, the cooling module has a first heat exchange channel 40 and a second heat exchange channel 42. The inlet of the first heat exchange channel 40 communicates with the water distribution box 212 via the first pump 213. The outlet of the first heat exchange channel 40 communicates with the water inlet 331 of the heating assembly 2 via the water distribution box 212 and the second pump 214. Since the inlet water of the water inlet 331 of the heating element 2 is absorbed into the discharge water of the first heat exchange channel 40, the temperature is relatively high and changes in real time, and because it is necessary to ensure that the water heated by the heating element 2 is boiling, the first measurement is set The temperature element 710 measures the temperature of the position of the water inlet 331 in real time, and controls the second pump 214 or the heating power to achieve a stable water outlet temperature.

Furthermore, as shown in FIG. 73, the target temperature T2 of t2 collected by the second temperature measuring element 720 is 90°C to 100°C. Generally, when the altitude is lower than 1000 meters, the target temperature T2 is further 95°C to 100°C. When t2 is lower than the target temperature T2, the temperature of t2 is increased by increasing the heating power or reducing the flow rate of the second pump 214. When t2 is at 100°C for a long time, reduce the heating power or increase the flow rate of the second pump 214 to reduce the temperature of t2.

Further, as shown in FIG. 73, the temperature measurement system 70 further includes a third temperature measurement element 730, which is provided at the liquid nozzle 34, and is used to sense the actual temperature t3 of the water outlet of the liquid nozzle 34. , The target temperature T3 of t3 is the temperature file selected by the user. When t3 does not reach the target temperature T3, the temperature of t3 is adjusted by controlling the first pump 213 to adjust the flow rate in the first heat exchange passage 40.

Further, as shown in FIG. 73, the temperature measurement system 70 further includes a fourth temperature measurement element 740, which is arranged at an upstream position of the first heat exchange channel 40, for example, when water enters the first heat exchange channel A fourth temperature measuring element 740 is provided in the channel before 40 to sense the temperature t4 of the cooling water inlet. Since the water temperature of t4 will affect the cooling water temperature t3, different cooling water flow control programs can be called according to the temperature of t4 to ensure the stability of the water temperature.

Further, as shown in FIG. 76, there is a fifth temperature measuring element 80 outside the waterway system 30. The fifth temperature measuring element 80 is used to sense the temperature t5 of the air. According to the temperature of the air, the transmission to the air can be predicted. The amount of heat, so as to predict the water temperature more accurately.

The cavity 313 communicates with the liquid outlet nozzle 34, the steam outlet pipe 311 and the inlet 312. Wherein, the cavity 313 enters water and water vapor from the inlet 312, and the liquid outlet 34 is formed at the bottom of the cavity 313 to facilitate the discharge of the water in the cavity 313 as much as possible. The steam outlet pipe 311 protrudes from the inner bottom surface of the cavity 313, and the end of the steam outlet pipe 311 away from the inner bottom surface of the cavity 313 is formed with an air inlet. The position of the air inlet is higher than that of the outlet nozzle 34 and the inlet 312. High to prevent water leakage in the steam outlet pipe 311.

As shown in Fig. 71, the heat exchange box 10 is similar to a plate heat exchanger. The heat exchange box 10 has a first heat exchange channel 40 and a second heat exchange channel 42. The first heat exchange channel 40 and the second heat exchange channel 42 are separated by a heat conducting plate, which can realize the first heat exchange channel 40 and the second heat exchange channel. The two heat exchange channels 42 exchange heat efficiently. Of course, this solution is not limited to this. In other implementations, the heat exchange box 10 can also be set as a tube heat exchanger, such as a shell-and-tube heat exchanger or a double-pipe heat exchanger.

Wherein, the upper part of the heating chamber 333 is provided with a boiling chamber 335, and the steam generated by heating in the heating chamber 333 is distributed in the boiling chamber 335 and discharged along the air holes on the boiling chamber 335. The heating chamber 333 or the boiling chamber 335 is provided with a water inlet 331 and/or a drain port 332 for the heating chamber 333 to enter and drain water.

This specific embodiment controls the heating power and the pump flow rate and flow rate of the pump through the temperature of each point detected by the temperature measurement system 70, thereby controlling the temperature of the boiling water and the temperature of the outlet water, so as to achieve both the sterilization effect of the product and the user The different outlet water temperature requirements and the stability of the outlet water temperature enhance the product experience.

In one of the working conditions of the product, the first temperature measuring element 710 at the water inlet 331 of the heating assembly 2 and the second temperature measuring element 720 at the drain 332 measure the temperature of the corresponding position. If the water outlet 332 of the heating assembly 2 The outlet water temperature is not within the set temperature range. For example, if the outlet water temperature of the water outlet 332 of the heating assembly 2 does not exceed a preset temperature threshold (such as 90°C to 100°C), then adjust the flow/velocity of the second pump 214 or The heating power of the heating assembly 2 makes the water outlet temperature of the water outlet 332 of the heating assembly 2 enter the set temperature range. In this way, it can be ensured that the water discharged from the liquid outlet nozzle 34 has a good sterilization effect after boiling, and the safety of use is improved.

In another working condition of the product, the third temperature measuring element 730 at the outlet nozzle 34 measures the temperature of the corresponding position to determine the temperature of the outlet water, and adjusts the first temperature at least according to the actual temperature measured by the third temperature measuring element 730 Liquid flow parameters in a heat exchange channel 40 (for example, by controlling the first pump 213 to adjust the flow rate, flow rate, etc.) in the first heat exchange channel 40, so that the temperature of the liquid outlet 34 can be controlled at the target temperature selected by the user. Further, a fourth temperature measuring element 740 is provided at the water inlet position of the first heat exchange channel 40 to measure the temperature, and the first pump is further controlled in combination with the inlet water temperature of the first heat exchange channel 40 collected by the fourth temperature measuring element 740 213 adjusts the flow or flow rate in the first heat exchange channel 40 and other parameters, so that the outlet water temperature of the liquid outlet nozzle 34 can be further finely controlled, and the outlet water temperature of the liquid outlet nozzle 34 can also be more stable. In addition, a fifth temperature measuring element 80 is provided to collect the ambient temperature. By determining the air temperature, the temperature measurement accuracy and control accuracy of each link can be better ensured, so as to better ensure the accuracy and temperature stability of the outlet water temperature.

As shown in FIG. 80, the embodiment of the sixth aspect of the present application provides a method for controlling a liquid heating appliance. For the liquid heating appliance in any embodiment of the above first aspect, the control method of the liquid heating appliance includes the following steps:

Step S1302, measuring the temperature of the waterway system;

Step S1304, controlling the heating power of the heating device and/or the liquid flow parameters in the waterway system according to the collected temperature of the waterway system.

The control method of the liquid heating appliance provided in the above-mentioned embodiment of the present application measures the temperature of the waterway system, and enables the control device to adjust the heating power of the heating device and/or the liquid flow parameters in the waterway system in time according to the temperature of the waterway system to form a waterway system Temperature control adjustment can improve the stability and accuracy of the product's outlet temperature, so that the actual outlet temperature of the product can better meet the outlet temperature requirements, improve the product experience, and has the advantages of fast response speed and high control accuracy, which can help improve the Thermal liquid heating products.

FIG. 81 is a schematic flowchart of a method for controlling a liquid heating appliance according to an embodiment of the application. The control method of the liquid heating appliance of this embodiment specifically includes the following steps:

Step S1402, collecting the temperature at the water inlet of the heating device in the waterway system;

In step S1404, at least the power parameter and the first flow parameter are generated according to the temperature at the water inlet, and the heating power of the heating device is controlled to the power parameter, and the flow rate at the water inlet is controlled to the first flow parameter.

For example, if you need to control the product to heat the liquid to 100°C to achieve good sterilization conditions, when the temperature collected at the water inlet of the heating device is 45°C, according to the information that the temperature at the water inlet is 45°C , It can be obtained that the heating demand is 55℃ (that is, the difference between 100℃ and 45℃). In this way, according to the law of conservation of energy, based on the heating demand, the appropriate power parameters of the heating device and the first flow parameter at the water inlet can be estimated , By adjusting the power of the heating device to the power parameter and the flow rate at the water inlet to the first flow rate parameter, this not only meets the sterilization requirements, but also guarantees the water outlet demand, and makes the water temperature of the heating device Always control roughly at the sterilization temperature set by the target (such as 100°C), the temperature fluctuation of the outlet water temperature of the heating device will not be too large, so that the fluctuation amount of the outlet water temperature of the water outlet will not be too large, and the heat exchange device will also exchange heat. More efficient.

Of course, this solution is not limited to this. For working conditions that need to control the temperature of the product outlet at 50°C and do not require sterilization, when the temperature at the inlet of the heating device is 20°C, according to the temperature at the inlet If the temperature is 20°C, the heating demand is 30°C (that is, the difference between 50°C and 20°C). In this way, the power parameters and water inlet of the suitable heating device can be estimated based on the heating demand according to the law of conservation of energy. By adjusting the power of the heating device to the power parameter and the flow rate at the water inlet to the first flow parameter at the first flow rate parameter, this not only satisfies the water outlet demand and temperature demand, but also makes the heating device The outlet water temperature is always roughly controlled at the target set outlet water temperature (for example, 50°C), and the outlet temperature fluctuation of the heating device will not be too large, so that the outlet temperature fluctuation of the water outlet will not be too large.

FIG. 82 is a schematic flowchart of a method for controlling a liquid heating appliance according to an embodiment of the application. The control method of the liquid heating appliance of this embodiment specifically includes the following steps:

Step S1502, collecting the temperature at the water outlet of the heating device in the waterway system;

In step S1504, if the temperature at the drain outlet is outside the target drain temperature range, adjust the heating power of the heating device and/or the flow rate at the water inlet so that the temperature at the drain outlet meets the target drain temperature range.

For example, when the temperature at the drain outlet is lower than the target drain temperature range (for example, the target drain temperature range is the sterilization target temperature range, more specifically, the sterilization target temperature range may be 90°C to 100°C, and further 92°C to 97°C, It is further from 94°C to 95°C; or, for example, the target drainage temperature interval is the outlet water target temperature interval. More specifically, the outlet water target temperature interval may be 30°C to 100°C, further 60°C to 90°C, and still further 65 ℃～85℃, the value interval can be set according to the product function or user needs), the heating power of the heating device can be appropriately increased and/or the flow rate (or flow velocity) at the water inlet of the heating device can be reduced to make the water drain The temperature at the outlet can rise to a certain extent to meet the target drainage temperature range; or for example, when the temperature at the drain outlet is higher than the target drainage temperature range, the heating power of the heating device can be appropriately reduced and/or the heating can be increased The flow rate (or flow rate) at the water inlet of the device allows the temperature at the water outlet to drop to a certain extent so as to meet the target water temperature range.

FIG. 83 is a schematic flowchart of a method for controlling a liquid heating appliance according to an embodiment of the application. The control method of the liquid heating appliance of this embodiment specifically includes the following steps:

Step S1602, collecting the temperature at the water outlet of the heating device in the waterway system;

In step S1604, if the temperature at the water outlet does not exceed the preset temperature threshold, increase the heating power of the heating device and/or reduce the flow rate at the water inlet.

For further example, the preset temperature threshold is 90°C to 100°C. The water temperature in the heating device can be approximately 90°C to 100°C, which has a good sterilization effect and improves food safety.

Furthermore, for products suitable for use at an altitude of less than 1000 meters, the preset temperature threshold is further set to 95°C to 100°C. This can make the sterilization effect of the product more secure.

In this solution, the temperature at the water outlet of the heating device is collected to feedback and adjust the heating power and/or the flow rate or flow rate of the water inlet, which can better improve the sterilization effect and stabilize the temperature of the water outlet.

Of course, it is understandable that the specific value of the preset temperature threshold in this solution is not limited by the above-exemplified 90°C-100°C, 95°C-100°C, etc., in fact, those skilled in the art can make specific The sterilization requirements for the flexibly adjust the specific values of the preset temperature thresholds, which will not be illustrated here one by one, but they are all within the protection scope of this solution without departing from the design concept.

FIG. 84 is a schematic flowchart of a method for controlling a liquid heating appliance according to an embodiment of the application. The control method of the liquid heating appliance of this embodiment specifically includes the following steps:

Step S1702, collecting the temperature at the water outlet of the heating device in the waterway system;

In step S1704, if the temperature at the water outlet within the first preset time period is at least the boiling temperature, the heating power of the heating device is reduced and/or the flow rate at the water inlet is increased.

For further example, the boiling temperature is 90°C to 100°C. It can meet the needs of a variety of altitudes, combine the product use environment to more accurately regulate the product, meet the need for sterilization, and better achieve product energy saving and emission reduction. Furthermore, the boiling temperature is 95°C to 100°C.

It is understandable that the specific value of the boiling temperature in this solution is not limited by the above-exemplified 90°C to 100°C. In fact, those skilled in the art can determine the above-mentioned boiling temperature according to the ambient pressure and specific boiling temperature requirements. The specific numerical value of the boiling temperature can be adjusted flexibly, which will not be illustrated one by one here, but it belongs to the protection scope of this scheme without departing from the design concept.

This solution collects feedback and adjusts the temperature at the drain outlet of the heating device within the first preset duration (the value of the first preset duration is, for example, 3s to 500s, further, for example, 10s to 400s, and further, for example, 15s to 200s). Heating power and/or the flow rate or flow rate of the water inlet. For example, when the temperature at the water outlet is at 100°C for a long time, reduce the heating power or increase the flow rate of the second pump to reduce the temperature at the water outlet to prevent the product from being high for a long time. Power operation, which is more conducive to component maintenance and energy saving and emission reduction.

FIG. 85 is a schematic flowchart of a method for controlling a liquid heating appliance according to an embodiment of the application. The control method of the liquid heating appliance of this embodiment specifically includes the following steps:

Step S1802, collecting the temperature at the water inlet of the heating device in the waterway system;

In step S1804, if the temperature of the water inlet shows an increasing trend within the second preset time period, the heating power of the heating device is reduced and/or the flow rate at the water inlet is increased.

It can be understood that since the water inflow of the heating device in this solution is at least partly derived from the drainage of the first medium channel, in this way, based on the change of the heat exchange amount of the heat exchange device, the temperature of the drainage of the first medium channel may change accordingly, resulting in heating The inlet water temperature of the device changes. In this solution, if the second preset duration (the second preset duration takes a value such as 2s～300s, further such as 5s～200s, and even further such as 6s～30s), it is continuously collected at the water inlet of the heating device. Increase the temperature, reduce the heating power of the heating device and/or increase the flow rate at the water inlet, so that the stability of the water outlet temperature of the heating device can be controlled more timely, and the problem of large fluctuations in the water outlet temperature of the heating device can be prevented. The nozzle temperature is correspondingly more stable and accurate, which prevents the product temperature control distortion problem, and is more conducive to accurate adjustment of the outlet temperature. In this way, the heat exchange load and temperature fluctuations of the heat exchange device are also smaller, which is more conducive to maintaining heat exchange The device operates efficiently and stably.

FIG. 86 is a schematic flowchart of a method for controlling a liquid heating appliance according to an embodiment of the application. The control method of the liquid heating appliance of this embodiment specifically includes the following steps:

Step S1902, collecting the temperature at the water outlet in the waterway system;

Step S1904, if the temperature at the water outlet is higher than the target water temperature corresponding to the target temperature command or the target gear command, increase the flow rate in the first medium channel of the water system; if the temperature at the water outlet is lower than the target temperature The target outlet water temperature corresponding to the command or target gear command reduces the flow rate in the first medium channel.

For example, if the target water temperature corresponding to the target temperature command or target gear command received by the product is 60°C, and when the temperature collected at the water outlet is 58°C, reduce the flow rate in the first medium channel In this way, the heat dissipation from the second medium channel to the first medium channel is reduced, so that the temperature at the water outlet can quickly rise to 60°C. If the temperature collected at the water outlet is 65°C, increase the first medium channel In this way, the heat dissipation from the second medium channel to the first medium channel increases, so that the temperature at the water outlet can be quickly dropped to 60°C. Of course, if the collected temperature at the water outlet is 60°C, the flow rate in the first medium channel can be maintained at the current flow rate. This feedback adjustment has higher response timeliness, and can realize the rapid adjustment of the water outlet temperature to the target value, so that the product outlet temperature is more accurate and stable, and the structure can ensure that the outlet water flow rate meets the demand and makes the outlet water flow rate more accurate. stable.

FIG. 87 is a schematic flowchart of a method for controlling a liquid heating appliance according to an embodiment of the application. The control method of the liquid heating appliance of this embodiment specifically includes the following steps:

Step S2002, collecting the inlet water temperature of the first medium channel of the waterway system;

Step S2004, generating a second flow parameter according to the target outlet temperature corresponding to the target temperature command or the target gear command and the inlet water temperature of the first medium channel, and controlling the flow rate of the first medium channel to the second flow parameter.

For example, if the target temperature command received by the product or the target gear command corresponds to the target outlet temperature of 55°C, if the collected water inlet temperature of the first medium channel is 20°C, according to the law of conservation of energy and The heat exchange efficiency of the heat exchange device can predict the heat exchange required to cool the water discharged from the heating device to 55°C. According to the required heat exchange and the inlet water temperature of the first medium channel at 20°C, the first The second flow parameter required by the medium channel is controlled by controlling the flow rate of the first medium channel to the second flow parameter. In this way, the instant heat of the product is better, and the outlet water temperature can be more stable, and it will not be hot and cold. It guarantees the user experience of the product, and has the advantages of good response timeliness and more precise control.

Fig. 88 is a schematic flowchart of a method for controlling a liquid heating appliance according to an embodiment of the application. The control method of the liquid heating appliance of this embodiment specifically includes the following steps:

Step S2102, collecting ambient temperature;

Step S2104, generating a first compensation parameter and/or a second compensation parameter according to the ambient temperature;

In step S2106, the heating power of the heating device is controlled to increase or decrease the first compensation parameter, and/or the liquid flow parameter in the waterway system is controlled to increase or decrease the second compensation parameter.

By collecting the ambient temperature and compensating the heating power and/or the liquid flow parameters of the water system based on the ambient temperature, the error of the outlet water temperature caused by the environmental temperature factor can be reduced, and the accuracy of the outlet water temperature can be improved.

For example, when the collected ambient temperature is 2°C and the required outlet water temperature is 80°C, the heat dissipation of the water discharged to the environment during the water receiving process can be estimated based on this, and the first compensation parameter and/or the first compensation parameter can be provided accordingly. The second compensation parameter, for example, increasing the heating power. The first compensation parameter (which can be a predetermined compensation value/scale factor or a value calculated according to a preset curve or a preset formula. It can be understood that the accuracy requirements are different, The compensation value/scale factor, preset curve and preset formula can be flexibly designed, and no special requirements and restrictions are made here), or the water volume of the first medium channel can be reduced by the second compensation parameter (which can be a predetermined compensation The value/scale factor can also be a value calculated according to a preset curve or a preset formula. It is understandable that for different accuracy requirements, the compensation value/scale factor, preset curve and preset formula can be flexibly designed, so I won’t do it here. Special requirements and restrictions) to make the actual drain temperature slightly higher than 80°C to properly compensate for the heat loss of the hot water. In this way, the hot water temperature obtained by the user is closer to 80°C, and the user experience is better, for example, it can be more accurately satisfied The brewing needs of users.

Of course, this embodiment is not limited to the above-mentioned example. In fact, the heating power of the heating device and/or the liquid flow parameters in the waterway system are controlled according to the environmental temperature feedback (specifically, adjusting the flow rate/velocity of the first medium channel). , The flow rate at the water inlet of the heating device, etc.) can be implemented in any of the above embodiments, so that the control parameter objects therein are well compensated, thereby reducing control errors and improving control accuracy. I will not give an example one by one here, but they all belong to the protection scope of this scheme without departing from the design concept.

Of course, the control method of the liquid heating appliance of this design is not limited to the case of any of the above embodiments. It is understandable that any of the above embodiments can also be combined in a non-conflicting manner. The detailed examples are as follows:

Step S2204, generating a power parameter and a first flow parameter at least according to the temperature at the water inlet, and controlling the heating power of the heating device to the power parameter, and controlling the flow rate at the water inlet to the first flow parameter;

Step S2206: If the temperature at the drain outlet is outside the target drain temperature range, adjust the heating power of the heating device and/or the flow rate at the water inlet so that the temperature at the drain outlet meets the target drain temperature range.

In this way, the power parameter and the first flow parameter are estimated according to the temperature of the water inlet, and the heating power of the heating device is controlled to the power parameter, and the flow at the water inlet is controlled to the first flow parameter, so that the water heated by the heating device The temperature does not deviate too much from the required heated water temperature, and water with sterilization effect can be basically obtained, with good sanitation and safety, and the working efficiency of the heating device can be taken into account at the same time to realize product energy saving. After that, by collecting the temperature at the drain outlet and performing feedback adjustment based on the temperature at the drain outlet, the temperature at the drain outlet can be more refined to meet the target drain temperature range. In this way, the sterilization effect is further guaranteed and the water quality is guaranteed. Good, and the energy-saving performance of the product can also be further optimized.
