Description

[0001] This application is a divisional application of a Chinese patent application with an application date of August 24, 2021, an application number of "202110976354.X", and an invention title of "Instant Heating Device and Its Control Method, Control Device, Water Treatment Device and Medium". Technical Field

[0002] The present invention relates to the field of instant heating technology, and in particular, to an instant heating device and its control method, control device, water treatment device and medium. Background Art

[0003] Instant heating products have the advantages of energy saving, small volume, low cost, etc., and are becoming more and more popular in daily life.

[0004] During the use of instant heating products, in different usage scenarios, the instant heating products may need to execute different power levels of the instant heating pipe. In particular, factors such as the inlet water temperature, the temperature of the heating component, and the AC grid voltage are not clear and are variable. Therefore, the combined scenarios are also changing in real time. If the usage scenario changes abnormally due to unpredictable reasons, it will further cause frequent and rapid switching of the power level of the heating component (such as switching on and off at a frequency of once every 0.2 seconds). In this way, it is extremely easy to cause damage to the heating component or electronic components, and even cause fuse ignition and the like. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0006] To this end, in the first aspect of the present invention, a control method for an instant heating device is provided.

[0007] In the second aspect of the present invention, a control device for an instant heating device is provided.

[0008] In the third aspect of the present invention, an instant heating device is provided.

[0009] In the fourth aspect of the present invention, a water treatment device is provided.

[0010] In the fifth aspect of the present invention, a readable storage medium is provided.

[0011] In the first aspect of the present invention, a control method for an instant heating device is provided. The instant heating device includes a heating component, and the control method includes: obtaining a gear control instruction for the heating component; based on the gear control instruction for switching the target gear of the heating component from the first gear to the second gear, controlling the heating component to switch to the second gear after a set delay.

[0012] The present invention provides a control method for an instant heating device, which can be applied to an instant heating device with a heating component. Specifically, the control method provided by the present invention can obtain the gear control instruction of the heating component during the operation of the instant heating device, and this gear control instruction is used to change the gear of the heating component. Among them, different gears correspond to different heating powers, and by changing the gear of the heating component, the heating power of the heating component can be changed.

[0013] During the operation of the instant heating device, after obtaining the above-mentioned gear control instruction, the control method provided by the present invention analyzes the gear control instruction and determines which gear the heating component will be controlled to or switched to under the control of this gear control instruction. If the heating component will change from the first gear to the second gear under the control of this gear control instruction; at this time, the control method provided by the present invention will not control the heating component to immediately switch gears, but will control the heating component to perform a delay operation, and after a preset delay duration, then control the heating component to switch to the above-mentioned second gear.

[0014] In this way, during the operation of the instant heating device, under the control of the control method provided by the present invention, when the heating component of the instant heating device changes from the first gear to the second gear, there will be a certain delay, which can reduce the frequency of gear switching of the heating component to a certain extent, and reduce the number of gear changes of the heating component within the same time. In this way, the service life of the heating component can be extended to a great extent, and at the same time, the service life of the electronic components used in conjunction with this heating component can be extended, and the service life of the entire instant heating device can be extended. Moreover, due to the above-mentioned delay control, the use safety of the instant heating device can be greatly improved, so that the heating component will not be easily fused, further ensuring the personal and property safety of users.

[0015] Therefore, for the control method of the instant heating device provided by the present invention, when the heating component of the instant heating device changes from the first gear to the second gear, it will not control the heating component to immediately switch gears, but will control the heating component to perform a delay operation, and then control the heating component to switch to the above-mentioned second gear after a preset delay duration. In this way, the service life and use safety of the heating component can be ensured, and at the same time, it is ensured that the heating component will not be easily fused, further ensuring the personal and property safety of users.

[0016] In some possible designs, the first gear includes an off gear, and the second gear includes an on gear.

[0017] In this technical solution, the first gear may include an off gear, and the second gear may include an on gear. That is, during the operation of the instant heating device, if the heating component changes from the off gear to the on gear under the control of the gear control instruction, instead of immediately controlling the heating component to switch gears, the heating component will be controlled to perform a delay operation, and after a preset delay duration, the heating component will be controlled to switch from the off gear to the on gear, achieving the delayed startup of the instant heating device.

[0018] Specifically, during the operation of the instant heating device, parameters such as the inlet water temperature, the temperature of the heating component, and the AC grid voltage are not clear and are variable. This causes the usage scenarios of the instant heating device to change, and the heating component will continuously switch gears to adapt to the real-time usage scenarios, especially continuous on and off operations. Frequent on and off of the heating component will seriously affect its service life and even cause the heating component to fuse and lead to fires, etc.

[0019] Therefore, during the operation of the instant heating device of the present invention, when the gear of the heating component changes, if the heating component changes from the off gear to the on gear, the heating component will be controlled to start after a preset delay duration. This can reduce the switching frequency of the gear of the heating component, play a certain protective role for the heating component, and at the same time extend the service life of the heating component and the entire instant heating device.

[0020] In some possible designs, the control method further includes: obtaining the target outlet water temperature of the heating component; based on the target outlet water temperature being within a preset temperature range, controlling the heating component to switch to the third gear.

[0021] In this design, during the operation of the instant heating device, the control method proposed by the present invention can obtain the target outlet water temperature of the heating component, which can be input by the user or default or calculated by the instant heating device. Then, it is judged whether the target outlet water temperature is within the preset temperature range; if the target outlet water temperature is within the preset temperature range, the heating component can be directly controlled to work in the third gear. In this way, specific control within the preset temperature range can be achieved, and thus, when the target outlet water temperature is within the preset temperature range, the frequent change of the gear of the heating component can be avoided.

[0022] In some possible designs, the third gear includes a zero gear.

[0023] In this design, the above preset temperature range can be the room temperature range, that is, the temperature range of the environment where the instant heating device is located. And the above third gear may include a zero gear. Specifically, the heating power corresponding to the zero gear is 0, and when the heating component is in the zero gear, no heating will be performed.

[0024] That is, when the control method proposed by the present invention determines that the target outlet water temperature is within the room temperature range, it controls the heating component to switch to the zero gear. At this time, the heating component does not heat the liquid, let alone switch gears. In this way, on the one hand, it can avoid frequent changes in the gear of the heating component to extend the service life of the heating component, and on the other hand, it can avoid the heating component consuming energy, thereby achieving the purpose of energy conservation.

[0025] In some possible designs, the control method further includes: obtaining the number of gear changes of the heating component within a preset duration; controlling the gear of the heating component according to the number of gear changes.

[0026] In this design, during the operation of the instant heating device, calculate the number of gear changes of the heating component within a preset duration, and then judge the gear change situation of the heating component according to the above number of gear changes. If the number of gear changes of the heating component within the preset duration is large, it means that the heating component is prone to damage in this case. Therefore, the gear of the heating component can be controlled according to the number of gear changes of the heating component within the preset duration, thereby avoiding damage to the heating component and ensuring the service life of the heating component.

[0027] In some possible designs, the preset duration includes a first preset duration, and the step of controlling the gear of the heating component according to the number of gear changes includes: based on the number of gear changes of the heating component within the first preset duration being greater than or equal to a first threshold, controlling the heating component to switch to a set gear.

[0028] In this design, the preset duration may include a first preset duration. During the process of controlling the gear of the heating component, first judge whether the number of gear changes of the heating component within the preset duration is greater than the first threshold or equal to the first threshold. If the judgment result is yes, it means that the gear of the heating component changes relatively frequently within the preset duration.

[0029] At this time, control the heating component to be in a fixed set gear, and control the heating component to be fixed in the set gear, so that the heating component works according to the set gear. In this way, it can greatly avoid damage to the heating component and ensure the service life of the heating component.

[0030] In some possible designs, based on the heating component switching to the set gear, prohibit the heating component from switching gears.

[0031] In this design, when the gear of the heating component changes frequently within a preset duration and the heating component has been fixed at a set gear, the gear of the heating component is restricted, and the gear of the heating component is controlled not to change until the current operation of the instant heating device ends. That is, when the gear of the heating component changes frequently within a preset duration and the heating component has been fixed at a set gear, even if the instant heating device receives a gear change instruction again, it will not control the heating component to switch to the corresponding target gear. In this way, the damage of the heating component can be greatly avoided, and the service life of the heating component is guaranteed.

[0032] In some possible designs, the preset duration includes a second preset duration, the instant heating device further includes a water supply component, and the step of controlling the gear of the heating component according to the number of gear changes includes: based on the number of gear changes of the heating component gear within the second preset duration being greater than or equal to a second threshold, controlling the heating component and the water supply component to stop working.

[0033] In this design, the preset duration may include a second preset duration. During the process of controlling the gear of the heating component, first, it is judged whether the number of gear changes of the heating component gear within the preset duration is greater than the second threshold or equal to the second threshold. If the judgment result is yes, it indicates that the gear of the heating component changes more frequently within the preset duration and the damage to the heating component is more serious. At this time, control the heating component to stop working, and at the same time, control the water supply component to stop working. In this way, the damage of the heating component can be greatly avoided, and the service life of the heating component is guaranteed.

[0034] That is, when the number of gear changes of the heating component gear within the preset duration is greater than the second threshold or equal to the second threshold, force the entire instant heating device to stop working, and control the water supply component and the heating component to stop working simultaneously. In this way, the damage of the heating component can be maximally avoided, and the service lives of the heating component, the water supply component, and the entire instant heating device are guaranteed.

[0035] In some possible designs, the control method further includes: based on the gear control instruction for switching the target gear of the heating component from the second gear to the first gear, controlling the heating component to directly switch to the first gear.

[0036] In this design, after receiving the gear control instruction, the control method proposed by the present invention analyzes the gear control instruction and judges which gear the heating component will change to or switch to under the control of the gear control instruction. If the heating component will change from the second gear to the first gear under the control of the gear control instruction, the control method proposed by the present invention can directly control the heating component to immediately switch to the above-mentioned first gear.

[0037] Specifically, the first gear includes a closed gear, and the second gear includes an open gear. That is, during the operation of the instant heating device of the present invention, when the gear of the heating component changes, if the heating component changes from the open gear to the closed gear, the heating component can be directly controlled to switch to the closed gear.

[0038] In some possible designs, the set duration is greater than or equal to 1 second and less than or equal to 2 seconds.

[0039] In this design, the set duration can be 1 second, 2 seconds, or any duration between 1 second and 2 seconds. Among them, if the set duration is less than 1 second, the delay operation effect of the heating component will be weak, resulting in relatively frequent changes in the gear of the heating component. If the set duration is greater than 2 seconds, the delay time of the heating component will be too long, thereby affecting the heating effect of the instant heating device.

[0040] Therefore, the present invention optimizes the set duration. The set duration can be 1 second, 2 seconds, or any duration between 1 second and 2 seconds. On the basis of ensuring the delayed change of the gear of the heating component, the continuous heating ability of the instant heating device is ensured, and thus the heating effect of the instant heating device is ensured.

[0041] The second aspect of the present invention provides a control device for an instant heating device. The instant heating device includes a heating component, and the control device includes: an acquisition unit that acquires a gear control instruction for the heating component; a control unit that, based on the gear control instruction, switches the target gear of the heating component from the first gear to the second gear, and the control unit is used to control the heating component to switch to the second gear after a set duration of delay.

[0042] The present invention proposes a control device for an instant heating device, which can be applied to an instant heating device having a heating component. Specifically, the control device proposed by the present invention includes a control unit and an acquisition unit. The acquisition unit can acquire the above-mentioned gear control instruction for the heating component during the operation of the instant heating device, and this gear control instruction is used to change the gear of the heating component. Among them, different gears correspond to different heating powers, and the heating power of the heating component can be changed by changing the gear of the heating component.

[0043] In addition, during the operation of the instant heating device, after the acquisition unit obtains the above-mentioned gear control instruction, it sends the gear control instruction to the control unit, and the control unit determines which gear the heating component will switch to under the control of this gear control instruction. If the heating component will change from the first gear to the second gear under the control of this gear control instruction, the control unit will not control the heating component to switch gears immediately, but will control the heating component to perform a delay operation, and after a preset duration of delay, then control the heating component to switch to the above-mentioned second gear.

[0044] In this way, during the operation of the instant heating device, under the control of the control device proposed by the present invention, when the heating component of the instant heating device changes from the first gear to the second gear, there will be a certain delay, which can reduce the frequency of gear switching of the heating component to a certain extent, and reduce the number of gear changes of the heating component within the same time. In this way, the service life of the heating component can be extended to a great extent, and at the same time, the service life of the electronic components used in cooperation with the heating component can be extended, and the service life of the entire instant heating device can be extended. Moreover, due to the above-mentioned delay control, the use safety of the instant heating device can be greatly improved, so that the heating component will not easily fuse, further ensuring the personal and property safety of users.

[0045] In some possible designs, the first gear includes an off gear, and the second gear includes an on gear.

[0046] In this design, the first gear may include an off gear, and the second gear may include an on gear. That is, during the operation of the instant heating device, if the heating component changes from the off gear to the on gear under the control of the gear control instruction, at this time, the heating component is not controlled to immediately switch gears, but the heating component is controlled to perform a delay operation, and after a preset delay duration, the heating component is then controlled to switch from the off gear to the on gear to achieve the delayed start of the instant heating device.

[0047] In some possible designs, the acquisition unit is further configured to acquire the target outlet water temperature of the heating component; the control unit is further configured to control the heating component to switch to the third gear based on the target outlet water temperature being within a preset temperature range.

[0048] In this design, during the operation of the instant heating device, the acquisition unit can obtain the target outlet water temperature of the heating component, which can be input by the user or default or calculated by the instant heating device. Then, the control unit determines whether the target outlet water temperature is within the preset temperature range; if the target outlet water temperature is within the preset temperature range, the control unit can directly control the heating component to work in the third gear. In this way, specific control within the preset temperature range can be achieved, and thus, when the target outlet water temperature is within the preset temperature range, the frequent change of the gear of the heating component can be avoided.

[0049] In some possible designs, the third gear includes a zero gear.

[0050] In this design, the above-mentioned preset temperature range can be the room temperature range, that is, the temperature range of the environment where the instant heating device is located. And the above-mentioned third gear may include a zero gear. In particular, the heating power corresponding to the zero gear is 0, and when the heating component is in the zero gear, no heating will be performed.

[0051] In some possible designs, the obtaining unit is further configured to obtain the number of gear changes of the heating component within a preset time period; the control unit is further configured to control the gear of the heating component according to the number of gear changes.

[0052] In this design, during the operation of the instant heating device, the obtaining unit calculates the number of gear changes of the heating component within a preset time period; the control unit determines the gear change situation of the heating component according to the above-mentioned number of gear changes. If the number of gear changes of the heating component within the preset time period is large, it indicates that the heating component is likely to be damaged in this case. Therefore, the control unit can control the gear of the heating component according to the number of gear changes of the heating component within the preset time period, thereby avoiding damage to the heating component and ensuring the service life of the heating component.

[0053] In some possible designs, the preset time period includes a first preset time period, and the control unit is specifically configured to control the heating component to switch to a set gear based on the number of gear changes of the heating component within the first preset time period being greater than or equal to a first threshold.

[0054] In this design, the preset time period may include a first preset time period. During the process of controlling the gear of the heating component, the control unit determines whether the number of gear changes of the heating component within the preset time period is greater than the first threshold or equal to the first threshold. If the judgment result is yes, it indicates that the gear of the heating component changes relatively frequently within the preset time period. At this time, the control unit controls the heating component to be at a fixed set gear and controls the heating component to be fixed at the set gear, so that the heating component works according to the set gear. In this way, damage to the heating component can be greatly avoided, and the service life of the heating component is ensured.

[0055] In some possible designs, the control unit is specifically configured to prohibit the heating component from switching gears based on the heating component switching to the set gear.

[0056] In this design, when the gear of the heating component changes relatively frequently within the preset time period and the heating component has been fixed at the set gear, the control unit restricts the gear of the heating component and controls the gear of the heating component not to change until the instant heating device finishes its current operation. That is, when the gear of the heating component changes relatively frequently within the preset time period and the heating component has been fixed at the set gear, even if the instant heating device receives a gear change instruction again, the control unit will not control the heating component to switch to the corresponding target gear. In this way, damage to the heating component can be greatly avoided, and the service life of the heating component is ensured.

[0057] In some possible designs, the preset duration includes a second preset duration. That is, the instant heating device further includes a water supply component. Specifically, the control unit is configured to control the heating component and the water supply component to stop working based on the number of gear changes of the heating component within the second preset duration being greater than or equal to a second threshold value.

[0058] In this design, the preset duration may include a second preset duration. During the process of controlling the gear of the heating component, the control unit first determines whether the number of gear changes of the heating component within the preset duration is greater than the second threshold value or equal to the second threshold value. If the determination result is yes, it indicates that the gear of the heating component changes more frequently within the preset duration, and the damage to the heating component is more serious. At this time, the control unit controls the heating component to stop working and also controls the water supply component to stop working. In this way, the damage to the heating component can be greatly avoided, and the service life of the heating component can be ensured.

[0059] In some possible designs, the control unit is further configured to directly switch the heating component to the first gear based on the gear control instruction for switching the target gear of the heating component from the second gear to the first gear.

[0060] In this design, if the heating component will change from the second gear to the first gear under the control of this gear control instruction, the control unit can directly control the heating component to immediately switch to the above-mentioned first gear. Specifically, the first gear includes the off gear, and the second gear includes the on gear.

[0061] In some possible designs, the set duration is greater than or equal to 1 second and less than or equal to 2 seconds.

[0062] In this design, the set duration can be 1 second, 2 seconds, or any duration from 1 second to 2 seconds. Among them, if the set duration is less than 1 second, the effect of the delay operation performed by the heating component will be weak, resulting in the gear of the heating component still changing relatively frequently. If the set duration is greater than 2 seconds, the delay time of the heating component will be too long, thereby affecting the heating effect of the instant heating device.

[0063] Therefore, the present invention optimizes the set duration. The preset duration can be 1 second, 2 seconds, or any duration from 1 second to 2 seconds. On the basis of ensuring the delayed change of the gear of the heating component, the continuous heating ability of the instant heating device is ensured, and thus the heating effect of the instant heating device is ensured.

[0085] In order to more clearly understand the above-mentioned objects, features, and advantages of the invention, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0086] In the following description, many specific details are set forth in order to fully understand the invention. However, the invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the invention is not limited by the specific embodiments disclosed below.

[0087] The following will refer to Figures 1 to 9 to describe an instant heating device, its control method and control device, a water treatment device, and a medium provided according to some embodiments of the present invention.

[0088] The first embodiment of the present invention proposes a control method for an instant heating device, which can be applied to an instant heating device having a heating component. As Figure 1 shown, the control method includes:

[0089] Step 102, obtaining a gear control instruction of the heating component;

[0090] Step 104, based on the gear control instruction, controlling the heating component to switch from the first gear to the second gear after a set delay time when the target gear of the heating component is switched from the first gear to the second gear.

[0091] The control method proposed in this embodiment can obtain the above-mentioned gear control instruction of the heating component during the operation of the instant heating device, and this gear control instruction is used to change the gear of the heating component. Among them, different gears correspond to different heating powers, and by changing the gear of the heating component, the heating power of the heating component can be changed.

[0092] During the operation of the instant heating device, after obtaining the above gear control instruction, the control method proposed in this embodiment analyzes the gear control instruction and determines which gear the heating component will change to or be controlled to under the control of this gear control instruction. If the heating component will change from the first gear to the second gear under the control of this gear control instruction.

[0093] At this time, the control method proposed in this embodiment will not directly control the heating component to immediately switch gears, but will control the heating component to perform a delay operation, and after delaying for a preset duration, then control the heating component to switch to the above second gear.

[0094] In this way, during the operation of the instant heating device, under the control of the control method proposed in this embodiment, when the heating component of the instant heating device changes from the first gear to the second gear, there will be a certain delay, which can reduce the frequency of gear switching of the heating component to a certain extent and reduce the number of gear changes of the heating component within the same time.

[0095] In this way, the service life of the heating component can be extended to a great extent, at the same time, the service life of the electronic components used in conjunction with the heating component and the service life of the entire instant heating device can be extended. And due to the above delay control, the use safety of the instant heating device can be greatly improved, so that the heating component will not easily fuse, further ensuring the personal and property safety of users.

[0096] Therefore, for the control method of the instant heating device proposed in this embodiment, when the heating component of the instant heating device changes from the first gear to the second gear, it will not directly control the heating component to immediately switch gears, but will control the heating component to perform a delay operation, and then control the heating component to switch to the above second gear after delaying for a preset duration. In this way, the service life and use safety of the heating component can be ensured, while ensuring that the heating component will not easily fuse, further ensuring the personal and property safety of users.

[0097] In this embodiment, further, the first gear may include a closed gear, and the second gear may include an open gear.

[0098] That is, during the operation of the instant heating device, if the heating component will change from the closed gear to the open gear under the control of the gear control instruction, at this time, the heating component will not be controlled to immediately switch gears, but will be controlled to perform a delay operation, and after delaying for a preset duration, then control the heating component to switch from the closed gear to the open gear to realize the delayed start of the instant heating device.

[0099] Specifically, during the operation of the instant heating device, parameters such as the inlet water temperature, the temperature of the heating component, and the AC grid voltage are all uncertain, and the above parameters are variable. This causes the usage scenario of the instant heating device to change as well. In order to adapt to the real-time usage scenario, the heating component will continuously switch gears, especially continuously turn on and off. Frequent on-off of the heating component will seriously affect its service life and may even cause the heating component to fuse and lead to fires, etc.

[0100] Therefore, in this embodiment, during the operation of the instant heating device, when the gear of the heating component changes, if the heating component changes from the off gear to the on gear, it will be controlled to delay for a preset duration before turning on. This can reduce the switching frequency of the gear of the heating component, play a certain protective role for the heating component, and at the same time extend the service life of the heating component and the entire instant heating device.

[0101] The second embodiment of the present invention proposes a control method for an instant heating device, which can be applied to an instant heating device with a heating component. As Figure 2 shown, the control method includes:

[0102] Step 202, obtain the target outlet water temperature of the heating component;

[0103] Step 204, based on the target outlet water temperature being within a preset temperature range, control the heating component to switch to the third gear.

[0104] During the operation of the instant heating device, the control method proposed by the present invention can obtain the target outlet water temperature of the heating component. This target outlet water temperature can be input by the user or default or calculated by the instant heating device. Then, it is judged whether the target outlet water temperature is within the preset temperature range; if the target outlet water temperature is within the preset temperature range, the heating component can be directly controlled to work in the third gear.

[0105] In this way, specific control within the preset temperature range can be realized, and thus, when the target outlet water temperature is within the preset temperature range, the frequent change of the gear of the heating component can be avoided.

[0106] In this embodiment, further, the above preset temperature range can be the room temperature range, that is, the temperature range of the environment where the instant heating device is located. And the above third gear can include the zero gear. In particular, the heating power corresponding to the zero gear is 0, and when the heating component is in the zero gear, no heating will be performed.

[0107] That is, when the control method proposed in this embodiment determines that the target outlet water temperature is within the room temperature range, it controls the heating component to switch to the zero gear. At this time, the heating component does not heat the liquid, let alone switch gears. In this way, on the one hand, it can avoid frequent changes in the gear of the heating component to extend the service life of the heating component, and on the other hand, it can avoid the heating component consuming energy, thereby achieving the purpose of energy conservation.

[0108] The third embodiment of the present invention proposes a control method for an instant heating device, which can be applied to an instant heating device with a heating component. As Figure 3 shown, the control method includes:

[0109] Step 302, obtaining the number of gear changes of the heating component within a preset duration;

[0110] Step 304, controlling the gear of the heating component according to the number of gear changes.

[0111] During the operation of the instant heating device, calculate the number of gear changes of the heating component within a preset duration, and then judge the gear change situation of the heating component according to the above number of gear changes. If the number of gear changes of the heating component within a preset duration is large, it means that the heating component is prone to damage in this case.

[0112] Therefore, the control method proposed in this embodiment can control the gear of the heating component according to the number of gear changes of the heating component within a preset duration, thereby avoiding damage to the heating component and ensuring the service life of the heating component.

[0113] It should be noted that the control methods defined in the first to third embodiments of the present invention do not exist in isolation, but can be combined with each other, and will not be explained one by one here.

[0114] The fourth embodiment of the present invention proposes a control method for an instant heating device. On the basis of the third embodiment, further:

[0115] The preset duration may include a first preset duration. During the process of controlling the gear of the heating component, first judge whether the number of gear changes of the heating component within the preset duration is greater than the first threshold or equal to the first threshold. If the judgment result is yes, it means that the gear of the heating component changes relatively frequently within the preset duration.

[0116] At this time, control the heating component to be in a fixed set gear, and control the heating component to be fixed in the set gear so that the heating component works according to the set gear. In this way, it can greatly avoid damage to the heating component and ensure the service life of the heating component.

[0117] In this embodiment, further, when the gear of the heating component changes frequently within a preset duration and the heating component has been fixed at a set gear, the gear of the heating component is restricted, and it is controlled that the gear of the heating component no longer changes until the current operation of the instant heating device ends.

[0118] That is, when the gear of the heating component changes frequently within a preset duration and the heating component has been fixed at a set gear, even if the instant heating device receives a gear change instruction again, it will not control the heating component to switch to the corresponding target gear. In this way, the damage of the heating component can be greatly avoided, and the service life of the heating component can be guaranteed.

[0119] In this embodiment, the set gear can be a gear of a threshold value, and the heating power of the heating component can be designed according to actual requirements at this gear. And after the heating component has been fixed at the set gear, the gear of the heating component no longer changes.

[0120] The fifth embodiment of the present invention proposes a control method for an instant heating device. On the basis of the third embodiment, further:

[0121] The preset duration can include a second preset duration. In the process of controlling the gear of the heating component, first, it is judged whether the number of gear changes of the heating component within the preset duration is greater than a second threshold value or equal to the second threshold value. If the judgment result is yes, it means that the gear of the heating component changes more frequently within the preset duration and the damage to the heating component is more serious. At this time, the heating component is controlled to stop working, and at the same time, the water supply component is also controlled to stop working. In this way, the damage of the heating component can be greatly avoided, and the service life of the heating component can be guaranteed.

[0122] That is, when the number of gear changes of the heating component within the preset duration is greater than the second threshold value or equal to the second threshold value, the entire instant heating device is forced to stop working, and the water supply component and the heating component are controlled to stop working simultaneously. In this way, the damage of the heating component can be maximally avoided, and the service lives of the heating component, the water supply component, and the entire instant heating device can be guaranteed.

[0123] The sixth embodiment of the present invention proposes a control method for an instant heating device. On the basis of the first embodiment, further:

[0124] For the control method of the embodiment of the present invention, after obtaining the gear control instruction, analyze the gear control instruction, and judge to which gear the heating component will change or be controlled under the control of the gear control instruction. If the heating component will change from the second gear to the first gear under the control of the gear control instruction, the control method proposed by the present invention can directly control the heating component to immediately switch to the above-mentioned first gear.

[0125] Specifically, the first gear includes an off gear, and the second gear includes an on gear. That is, during the operation of the instant heating device of the present invention, when the gear of the heating component changes, if the heating component changes from the on gear to the off gear, the heating component can be directly controlled to switch to the off gear.

[0126] The seventh embodiment of the present invention proposes a control method for an instant heating device. On the basis of the first embodiment, further:

[0127] The set duration can be 1 second, 2 seconds, or any duration between 1 second and 2 seconds.

[0128] Among them, if the set duration is less than 1 second, the delay operation effect of the heating component will be weak, resulting in relatively frequent changes in the gear of the heating component. If the set duration is greater than 2 seconds, the delay time of the heating component will be too long, thereby affecting the heating effect of the instant heating device.

[0129] Therefore, the present invention optimizes the set duration. The set duration can be 1 second, 2 seconds, or any duration between 1 second and 2 seconds. On the basis of ensuring the delayed change of the gear of the heating component, the continuous heating ability of the instant heating device is ensured, and thus the heating effect of the instant heating device is ensured.

[0130] In a specific embodiment, the preset duration can be 1 second, 1.2 seconds, 1.5 seconds, 1.8 seconds, 2 seconds, etc., and no specific limitation is made here, which can be understood by those skilled in the art.

[0131] As Figure 4 shown, the eighth embodiment of the present invention proposes a control device 400 for an instant heating device, which can be applied to an instant heating device having a heating component. Specifically, the control device 400 for the instant heating device proposed by the present invention includes a control unit 404 and an acquisition unit 402.

[0132] Among them, the acquisition unit 402 can acquire the above-mentioned gear control instruction of the heating component during the operation of the instant heating device, and this gear control instruction is used to change the gear of the heating component. Different gears correspond to different heating powers, and by changing the gear of the heating component, the heating power of the heating component can be changed.

[0133] In addition, during the operation of the instant heating device, after the acquisition unit 402 obtains the above gear control instruction, it sends the gear control instruction to the control unit 404, and the control unit 404 determines which gear the heating component will be controlled to or switched to under the control of this gear control instruction. If the heating component will change from the first gear to the second gear under the control of this gear control instruction, the control unit 404 will not control the heating component to immediately switch gears, but will control the heating component to perform a delay operation, and after a preset delay duration, then control the heating component to switch to the above second gear.

[0134] In this way, during the operation of the instant heating device, under the control of the control device 400 proposed by the present invention, there will be a certain delay in the process of the heating component of the instant heating device changing from the first gear to the second gear, which can reduce the frequency of gear switching of the heating component to a certain extent, and can reduce the number of gear changes of the heating component within the same time.

[0135] In this way, the service life of the heating component can be extended to a great extent, and at the same time, the service life of the electronic components used in cooperation with the heating component can be extended, and the service life of the entire instant heating device can be extended. Moreover, due to the above delay control, the use safety of the instant heating device can be greatly improved, so that the heating component will not easily melt, further ensuring the personal and property safety of users.

[0136] In this embodiment, further, the first gear may include an off gear, and the second gear may include an on gear.

[0137] That is to say, during the operation of the instant heating device, if the heating component will change from the off gear to the on gear under the control of the gear control instruction, at this time, the heating component is not controlled to immediately switch gears, but the heating component is controlled to perform a delay operation, and after a preset delay duration, the heating component is then controlled to switch from the off gear to the on gear to achieve the delayed start of the instant heating device.

[0138] Specifically, during the operation of the instant heating device, since parameters such as the inlet water temperature, the temperature of the heating component, and the AC grid voltage are not clear, and the above parameters are variable. The usage scenario of the instant heating device will also change, and the heating component will continuously switch gears to adapt to the real-time usage scenario, especially continuously turn on and off, and the frequent on-off of the heating component will seriously affect its service life, and even cause the heating component to melt and cause fires, etc.

[0139] Therefore, during the operation of the instant heating device in this embodiment, when the gear of the heating component changes, if the heating component changes from the off gear to the on gear, it will control the heating component to turn on after a preset time delay. This can reduce the switching frequency of the gear of the heating component, play a certain protective role for the heating component, and at the same time extend the service life of the heating component and the entire instant heating device.

[0140] The ninth embodiment of the present invention proposes a control device 400 for an instant heating device. On the basis of the eighth embodiment, further:

[0141] During the operation of the instant heating device, the acquisition unit 402 can obtain the target water outlet temperature of the heating component. This target water outlet temperature can be input by the user, or can be the default or calculated value of the instant heating device.

[0142] Then, the control unit 404 determines whether the target water outlet temperature is within a preset temperature range; if the target water outlet temperature is within the preset temperature range, the control unit 404 can directly control the heating component to work at the third gear. In this way, specific control within the preset temperature range can be realized, and further, when the target water outlet temperature is within the preset temperature range, the frequent change of the gear of the heating component can be avoided.

[0143] In this embodiment, further, the above preset temperature range can be the room temperature range, that is, the temperature range of the environment where the instant heating device is located. And the above third gear can include the zero gear. In particular, the heating power corresponding to the zero gear is 0, and when the heating component is in the zero gear, heating will not be performed.

[0144] That is to say, when the control method proposed in this embodiment determines that the target water outlet temperature is within the room temperature range, it controls the heating component to switch to the zero gear. At this time, the heating component does not heat the liquid, and the gear will not change either. In this way, on the one hand, the frequent change of the gear of the heating component can be avoided to extend the service life of the heating component, and on the other hand, the energy consumption of the heating component can be avoided, thereby achieving the purpose of energy saving.

[0145] The tenth embodiment of the present invention proposes a control device 400 for an instant heating device. On the basis of the eighth embodiment, further:

[0146] During the operation of the instant heating device, the acquisition unit 402 calculates the number of gear changes of the heating component within a preset time; the control unit 404 judges the gear change situation of the heating component according to the above number of gear changes.

[0147] If the number of gear changes of the heating component within a preset duration is relatively large, it indicates that the heating component is prone to damage in this case. Therefore, the control unit 404 can control the gear of the heating component according to the number of gear changes of the heating component within the preset duration, thereby avoiding damage to the heating component and ensuring the service life of the heating component.

[0148] Therefore, the control device 400 of the instant heating device proposed in this embodiment can control the gear of the heating component according to the number of gear changes of the heating component within the preset duration, thereby avoiding damage to the heating component and ensuring the service life of the heating component.

[0149] The eleventh embodiment of the present invention proposes a control device 400 of an instant heating device. On the basis of the tenth embodiment, further:

[0150] The preset duration may include a first preset duration. During the process of controlling the gear of the heating component, the control unit 404 determines whether the number of gear changes of the heating component within the preset duration is greater than the first threshold or equal to the first threshold.

[0151] If the judgment result is yes, it indicates that the gear of the heating component changes relatively frequently within the preset duration. At this time, the control unit 404 controls the heating component to be at a fixed set gear and controls the heating component to be fixed at the set gear, so that the heating component operates according to the set gear. In this way, damage to the heating component can be avoided to a great extent, and the service life of the heating component can be ensured.

[0152] In this embodiment, further, when the gear of the heating component changes relatively frequently within the preset duration and the heating component has been fixed at the set gear, the control unit 404 restricts the gear of the heating component and controls the gear of the heating component not to change until the instant heating device finishes working this time.

[0153] That is, when the gear of the heating component changes relatively frequently within the preset duration and the heating component has been fixed at the set gear, even if the instant heating device receives a gear change instruction again, the control unit 404 will not control the heating component to switch to the corresponding target gear. In this way, damage to the heating component can be avoided to a great extent, and the service life of the heating component can be ensured.

[0154] In this embodiment, the set gear can be a gear of the threshold, and the heating power of the heating component at this gear can be designed according to actual needs. And after the heating component has been fixed at the set gear, the gear of the heating component will no longer change.

[0155] The twelfth embodiment of the present invention proposes a control device 400 for an instant heating device. On the basis of the tenth embodiment, further:

[0156] The preset duration may include a second preset duration. During the process of controlling the gear of the heating component, the control unit 404 first determines whether the number of gear changes of the heating component within the preset duration is greater than the second threshold or equal to the second threshold.

[0157] If the judgment result is yes, it means that the gear of the heating component changes more frequently within the preset duration, and the damage to the heating component is more serious. At this time, the control unit 404 controls the heating component to stop working, and also controls the water supply component to stop working. In this way, the damage to the heating component can be greatly avoided, and the service life of the heating component can be guaranteed.

[0158] That is, when the number of gear changes of the heating component within the preset duration is greater than the second threshold or equal to the second threshold, the entire instant heating device is forced to stop working, and the water supply component and the heating component are controlled to stop working at the same time. In this way, the damage to the heating component can be maximally avoided, and the service lives of the heating component, the water supply component, and the entire instant heating device can be guaranteed.

[0159] The thirteenth embodiment of the present invention proposes a control device 400 for an instant heating device. On the basis of the eighth embodiment, further:

[0160] If the heating component will change from the second gear to the first gear under the control of this gear control instruction, the control unit 404 can directly control the heating component to immediately switch to the above-mentioned first gear. Specifically, the first gear includes a closed gear, and the second gear includes an open gear. That is, during the operation of the instant heating device of the present invention, when the gear of the heating component changes, if the heating component changes from the open / closed gear to the closed gear, the heating component can be directly controlled to switch to the closed gear.

[0161] The fourteenth embodiment of the present invention proposes a control device 400 for an instant heating device. On the basis of the eighth embodiment, further:

[0162] In this design, the set duration can be 1 second, 2 seconds, or any duration from 1 second to 2 seconds. Among them, if the set duration is less than 1 second, the delay operation effect of the heating component will be weak, and the gear of the heating component will still change relatively frequently. If the set duration is greater than 2 seconds, the delay time of the heating component will be too long, which will affect the heating effect of the instant heating device.

[0163] Therefore, the present invention optimizes the set duration, which can be 1 second, 2 seconds, or any duration between 1 second and 2 seconds. On the basis of ensuring the stepped delay change of the heating component, the continuous heating capacity of the instant heating device is ensured, and thus the heating effect of the instant heating device is ensured.

[0164] In a specific embodiment, the preset duration can be 1 second, 1.2 seconds, 1.5 seconds, 1.8 seconds, 2 seconds, etc., and specific limitations are not made here, which can be understood by those skilled in the art.

[0165] Such as Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown in

[0166] In addition, the instant heating device further includes a water supply component 504 and a heating component 502. Among them, the water supply component 504 can be used to pump liquid, and the above-mentioned heating component 502 can be used to heat the liquid driven by the water supply component 504. And, the control device of the above-mentioned instant heating device is electrically connected to the water supply component 504 and the heating component 502, and can control the water supply component 504 and the heating component 502 to work according to the actual situation.

[0167] In addition, the instant heating device proposed by the present invention also has the following advantages: energy saving; the instant heating device heats water as needed, and there is no need to carry out long-term hot water reserve work such as heating and heat preservation inside the instant heating device, reducing energy loss. The product volume is reduced, and the space adaptability is high. Since there is no need for hot water reserve inside the instant heating device, the structural design can reduce the product volume and the cost is low.

[0168] In addition, since there is no need for a water storage heat tank and related heating detection elements inside the instant heating device, the product cost can be reduced. Users can set the outlet water temperature and the water output according to their needs, and the temperature control unit and volume calculation unit inside the instant heating device can quickly and accurately reach the target temperature by heating and adjusting the water flow rate to meet the user's water outlet requirements.

[0169] The sixteenth embodiment of the present invention provides a water treatment device (not shown in the figure), including the instant heating device as described in the above embodiment.

[0170] The water treatment device proposed by the present invention includes the instant heating device as described in the above technical solution. Therefore, it has all the beneficial effects of the above-mentioned instant heating device, which will not be elaborated here one by one.

[0171] In this embodiment, further, the water treatment device includes but is not limited to water dispensers, water heaters, and water purifiers. They will not be listed one by one here.

[0172] The seventeenth embodiment of the present invention provides a readable storage medium (not shown in the figure). Among them, a program is stored on the readable storage medium.

[0173] Among them, when the program stored on the readable storage medium is executed, the steps of the control method of the instant heating device in any of the above embodiments can be realized. Therefore, it has all the beneficial effects of the above control method of the instant heating device, and will not be elaborated here one by one.

[0174] Instant heating products have the advantages of energy saving, small volume, low cost, etc., and are becoming more and more popular in daily life.

[0175] However, during the use of instant heating products, in different usage scenarios, the instant heating products may need to execute different power levels of the instant heating tube. In particular, factors such as the inlet water temperature, the temperature of the heating component, and the AC grid voltage are not clear and variable. Therefore, the combined scenarios are also changing in real time. If the usage scenario changes abnormally due to unpredictable reasons, it will lead to frequent and rapid switching of the power level of the heating component (such as switching on and off at a frequency of once every 0.2 seconds). In this way, it is extremely easy to cause damage to the heating component or electronic components, and even cause fuse ignition and the like.

[0176] Therefore, the present invention proposes a control method for an instant heating device, which can prevent the frequent switching of the power levels of the heating component and achieve the purpose of protecting the reliable operation of the instant heating device.

[0177] Specifically, the control method of the instant heating device proposed by the present invention can protect the heating component and the entire instant heating device through the following mechanisms:

[0178] Command interval protection mechanism: If the target power level of the heating component is the off power level, there is no delay and it is executed immediately; if the target power level switches from the off power level to the on power level, it is executed after a set delay to prevent the power levels from continuously switching on and off quickly. For example, when the target power level switches from the off power level to the on power level, it can be controlled to execute after a delay of 1.2 seconds.

[0179] Abnormal protection mechanism: When the target outlet water temperature of the heating component is normal water temperature (that is, the target outlet water temperature is within the preset temperature range and the instant heating device directly discharges water without heating), the power level of the heating component is forced to be zero.

[0180] Frequent switching limit mechanism: When it is detected that the number of gear changes of the heating component within the first preset duration is greater than the first threshold or equal to the first threshold (both are the on gears), control the heating component to directly switch to the set gear, and do not allow the heating component to switch gears again until the current water outlet ends. For example: When it is detected that the number of gear changes of the heating component within 3 seconds exceeds 4 times (both are non-on gears), control the heating component to directly switch to the set gear, and do not allow the heating component to switch gears again until the current water outlet ends.

[0181] Frequent switching prevention mechanism: When it is detected that the number of gear changes of the heating component within the second preset duration is greater than the second threshold or equal to the second threshold (both are the on gears), directly control the instant heating device to stop working (including controlling the heating component to stop working and controlling the water supply component to stop working). For example: When it is detected that the number of gear changes of the heating component within 3 seconds exceeds 7 times (both are non-on gears), control the heating component to directly switch to the set gear, and do not allow the heating component to switch gears again until the current water outlet ends.

[0182] It should be noted here that the above first preset duration and the second preset duration may be equal or unequal; the above second threshold is greater than the first threshold.

[0183] In addition, during the operation of the instant heating device, if the number of gear changes of the heating component within the first preset duration is greater than the first threshold or equal to the first threshold, the heating component will be directly controlled to switch to the set gear, and the heating component is not allowed to switch gears again. Therefore, when the instant heating device is not faulty, the heating component will not switch gears again. However, when the instant heating module is faulty, the heating component will still switch gears. At this time, if the number of gear changes of the heating component within the second preset duration is greater than the second threshold or equal to the second threshold, the entire instant heating device will be directly controlled to stop working. In this way, the safety and reliability of the instant heating device can be effectively improved. Those skilled in the art can also understand the above process.

[0184] Next, in combination with Figure 9 , a specific embodiment is used to explain the control method of the instant heating device proposed by the present invention. As Figure 9 shown, the control method includes:

[0185] Step 502, determine whether the heating component is in the first gear. If the determination result is yes, execute step 504; otherwise, execute step 506;

[0186] Step 504, determine whether the target gear changes from the first gear to the second gear. If the determination result is yes, execute step 508; otherwise, execute step 506;

[0187] Step 506, control the heating component to directly change to the second gear;

[0188] Step 508, control the heating component to change to the second gear after a set delay duration;

[0189] Step 510, determine whether the target outlet water temperature is within the preset temperature range. If the judgment result is yes, execute Step 512; otherwise, execute Step 514;

[0190] Step 512, control the heating component to change to the third gear;

[0191] Step 514, determine whether the number of gear changes of the heating component within the first preset duration is greater than or equal to the first threshold. If the judgment result is yes, execute Step 516; otherwise, execute Step 518;

[0192] Step 516, control the heating component to change to the set gear;

[0193] Step 518, determine whether the number of gear changes of the heating component within the second preset duration is greater than or equal to the second threshold. If the judgment result is yes, execute Step 520; otherwise, end;

[0194] Step 520, control the instant heating device to stop operating, and this water outlet is forced to end.

[0195] Therefore, after receiving the gear control instruction, determine whether the heating component is in the first gear at this time; if the heating component is not in the first gear at this time, it means that the heating component is already in the on state, so directly control the heating component to directly change to the second gear. If the heating component is in the first gear at this time, it means that the heating component is currently in the off state. At this time, judge whether the target gear changes from the first gear to the second gear; if the judgment result is yes, it is necessary to control the heating component to change to the second gear after a set delay duration; if the judgment result is no, directly control the heating component to directly change to the second gear.

[0196] Further, determine whether the target outlet water temperature is within the preset temperature range; if the judgment result is yes, it means that the target outlet water temperature is within the preset temperature range, and the instant heating device does not heat and directly discharges water. At this time, control the heating component to change to the third gear (i.e., the zero gear); if the judgment result is no, control the heating component to switch to the gear corresponding to the target outlet water temperature.

[0197] Further, it is determined whether the number of gear changes of the heating component within the first preset duration is greater than the first threshold or equal to the first threshold. If the determination result is yes, it indicates that the gear of the heating component is relatively frequent within the first preset duration. At this time, the heating component is directly controlled to switch to the set gear, and the heating component is not allowed to switch gears again until the current water outlet ends. If the determination result is yes, the heating component can be controlled to work normally.

[0198] Further, it is determined whether the number of gear changes of the heating component within the second preset duration is greater than the second threshold or equal to the second threshold. If the determination result is yes, it indicates that the gear of the heating component is even more frequent within the first preset duration. At this time, the instant heating device is directly controlled to stop working (including controlling the heating component to stop working and controlling the water supply component to stop working). If the determination result is yes, the heating component can be controlled to work normally.

[0199] It should be noted here that the above first preset duration and the second preset duration may be equal or unequal; the above second threshold is greater than the first threshold.

[0200] In addition, during the operation of the instant heating device, if the number of gear changes of the heating component within the first preset duration is greater than the first threshold or equal to the first threshold, the heating component will be directly controlled to switch to the set gear, and the heating component is not allowed to switch gears again. Therefore, in the case where the instant heating device does not malfunction, the heating component will not switch gears again. However, when the instant heating module malfunctions, the heating component will still switch gears. At this time, if the number of gear changes of the heating component within the second preset duration is greater than the second threshold or equal to the second threshold, the entire instant heating device will be directly controlled to stop working. In this way, the safety and reliability of the instant heating device can be effectively improved.
