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 "202110977628.7", and an invention title of "Instant heating device and its control method and 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 and control device, a water treatment device and a medium. Background Art

[0003] Due to the limitation of the production process level, each component of the instant heating device has its own tolerance. For example, the rated power tolerance level of the heating component is between -10% and +5%, and the water flow rate tolerance of the water supply component at the same driving value is ±20%. Just the error superposition of these two important components, the tolerance of the heating capacity value of the mass-produced instant heating device has reached about -30% to +25%. In addition, there are also errors such as water temperature sensor error, pipeline structure / size error, and airtightness error of the instant heating device. The superposition of various errors will be more serious.

[0004] Therefore, during the actual use of the instant heating device, problems such as the outlet water temperature not reaching the target temperature, the temperature rising too slowly, the temperature rising too fast, the temperature overshoot being too large, or the temperature being unable to be stabilized will occur. 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, the first aspect of the present invention provides a control method for an instant heating device.

[0007] The second aspect of the present invention provides a control device for an instant heating device.

[0008] The third aspect of the present invention provides an instant heating device.

[0009] The fourth aspect of the present invention provides a water treatment device.

[0010] The fifth aspect of the present invention provides a readable storage medium.

[0011] The first aspect of the present invention provides a control method for an instant heating device, including: obtaining the inlet water temperature and the outlet water temperature of the instant heating device; determining the difference between the outlet water temperature and the inlet water temperature, and taking the difference as the temperature difference value of the instant heating device; and determining the heating capacity value according to the temperature difference value and the parameter value of the instant heating device group.

[0012] The regulation method of the instant heating device proposed by the present invention can calculate the heating capacity value of a single instant heating device before the whole batch of instant heating devices leave the factory, thereby ensuring that each instant heating device has an accurate heating capacity value, avoiding the errors and impacts of various components of the instant heating device, and ensuring that the instant heating device can accurately heat the water flow to the specified temperature during use, realizing precise control of the water temperature.

[0013] The present invention first obtains the inlet water temperature before the instant heating device is heated and the outlet water temperature after the instant heating device is heated; then, calculates the difference between the outlet water temperature and the inlet water temperature, and takes the difference between the outlet water temperature and the inlet water temperature as the temperature difference value of the instant heating device. Then, according to the above temperature difference value and parameter value, the heating capacity value of this instant heating device is calculated, thereby realizing the learning process of the heating capacity value of a single instant heating device and ensuring the accuracy of the heating capacity value of a single instant heating device.

[0014] It should be noted here that the instant heating device includes a heating component and a water supply component. The above heating capacity value refers to: the heating capacity value reflected by the maximum stable temperature rise generated by the instant heating device when the heating component is driven by a fixed power supply voltage and the water supply component is driven by a fixed driving voltage. Those skilled in the art can understand the concept of the above heating capacity value.

[0015] Therefore, the regulation method of the instant heating device proposed by the present invention can accurately calculate the true heating capacity value of the instant heating device, effectively solve the technical problem of inaccurate heating capacity value caused by the superposition of tolerances of various components in the instant heating device, enable the instant heating device to determine the accurate heating capacity value according to its actual situation, and ensure the best performance effect and water outlet control of the instant heating device.

[0016] In some possible designs, the parameter value includes a temperature difference standard value and a maximum temperature difference value.

[0017] In this design, the parameter value includes a temperature difference standard value and a maximum temperature difference value. That is, the present invention can determine the heating capacity value of the heating device according to the temperature difference value of the instant heating device and the above temperature difference standard value and maximum temperature difference value. It can be understood that the above temperature difference standard value is a parameter value related to the outlet water temperature and the inlet water temperature of the instant heating device, and the above maximum temperature difference value is also a parameter value related to the outlet water temperature and the inlet water temperature of the instant heating device. The outlet water temperature and the inlet water temperature of the instant heating device also reflect the heating capacity value of the instant heating device.

[0018] In some possible designs, determining the heating capacity value of the instant heating device according to the temperature difference value and the parameter value specifically includes: determining the first difference between the temperature difference value and the temperature difference standard value; determining the second difference between the maximum temperature difference value and the temperature difference standard value; and determining the heating capacity value according to the proportional relationship between the first difference and the second difference.

[0019] In this design, when determining the heating capacity value of the instant heating device, the first difference between the temperature difference value of the instant heating device and the standard temperature difference value, and the second difference between the maximum temperature difference and the standard temperature difference value are calculated respectively; then, according to the proportional relationship between the first difference and the second difference, the heating capacity value of the instant heating device is determined. Specifically, the heating capacity value of the above-mentioned instant heating device can be obtained according to the ratio between the first difference and the second difference.

[0020] In some possible designs, the parameter values are preset in the instant heating device.

[0021] In this design, the parameter values can be preset in the instant heating device. Specifically, they can be preset in the main control board of the instant heating device. That is to say, when determining the heating capacity value of the instant heating device, the above-mentioned parameter values stored in advance can be directly retrieved.

[0022] Particularly, the process of storing the parameter values has been completed during the design or manufacturing process of the instant heating device. Specifically, during the process of selecting the parameter values, they can be confirmed according to the tolerance combinations of the various components of the instant heating device.

[0023] In some possible designs, the parameter values are determined according to the parameter values of one instant heating device among multiple instant heating devices.

[0024] In this design, the parameter values can be determined according to the parameter values of one instant heating device among multiple instant heating devices. Specifically, during the production process of the instant heating device, multiple instant heating devices will be manufactured. Therefore, the present invention can select one of the multiple instant heating devices as the target instant heating device, and select the relevant parameters of this target instant heating device as the above-mentioned parameter values. Particularly, the target instant heating device can be in the same batch as the instant heating device for which the heating capacity value is to be calculated, or can be in a different batch from the instant heating device for which the heating capacity value is to be calculated.

[0025] In some possible designs, the parameter values are determined according to the heating power of the heating component of the instant heating device and the liquid flow rate of the water supply component of the instant heating device.

[0026] In this design, the parameter values based on which the present invention determines the heating capacity value of the instant heating device are determined according to the heating power of the heating component of the instant heating device and the liquid flow rate of the water supply component of the instant heating device. In this way, during the process of calculating the heating capacity value, the heating power of the above-mentioned heating component and the liquid flow rate of the water supply component can be fully considered to ensure that the calculation result of the heating capacity value is more accurate.

[0027] In some possible designs, the parameter values are determined through the following process: controlling the heating component to operate at the nominal maximum power and the water supply component to operate at the nominal minimum flow rate to obtain the maximum outlet water temperature; controlling the heating component to operate at the nominal minimum power and the water supply component to operate at the nominal maximum flow rate to obtain the minimum outlet water temperature; taking the difference between the maximum outlet water temperature and the inlet water temperature as the maximum temperature difference; selecting any temperature value between the maximum outlet water temperature and the minimum outlet water temperature; and taking the difference between the temperature value and the inlet water temperature as the standard temperature difference.

[0028] In this design, each instant heating device has a nominal power range and a nominal flow rate range. When the inlet water temperature is the same, if the instant heating device operates at different heating powers, the outlet water temperature will also be different; correspondingly, when the inlet water temperature is the same, if the instant heating device operates at different liquid flow rates, the outlet water temperature will also be different.

[0029] Therefore, the determination process of the above maximum temperature difference and standard temperature difference is as follows:

[0030] First, control the heating component to operate at the nominal maximum power, and at the same time control the water supply component to operate at the nominal minimum flow rate. Under this state, obtain the maximum outlet water temperature of the instant heating device; then, control the heating component to operate at the nominal minimum power, and at the same time control the water supply component to operate at the nominal maximum flow rate. Under this state, obtain the minimum outlet water temperature of the instant heating device.

[0031] In this way, calculate the difference between the maximum outlet water temperature and the inlet water temperature, and take this difference as the maximum temperature difference.

[0032] In this way, select any temperature value between the maximum outlet water temperature and the minimum outlet water temperature, calculate the difference between this temperature value and the inlet water temperature, and take this difference as the above standard temperature difference.

[0033] In some possible designs, the temperature value is the average of the maximum outlet water temperature and the minimum outlet water temperature.

[0034] In this design, the temperature value is the average of the maximum outlet water temperature and the minimum outlet water temperature. That is, in the process of calculating the standard temperature difference, first calculate the average of the maximum outlet water temperature and the minimum outlet water temperature, then calculate the difference between this average value and the inlet water temperature, and take this difference as the above standard temperature difference.

[0035] In some possible designs, the regulation method of the instant heating device further includes: storing the heating capacity value; and controlling the driving value of the water supply component and / or the heating component of the instant heating device according to the heating capacity value.

[0036] In this design, after calculating the heating capacity value, store the calculated heating capacity for the subsequent use of the instant heating device.

[0037] In addition, after obtaining the heating capacity value of the instant heating device, the instant heating device can be controlled to operate according to the heating capacity value. Specifically, it is to control the water supply component or the heating component of the instant heating device to operate, or it can also be to control the water supply component and the heating component to operate simultaneously.

[0038] In some possible designs, before the step of determining the difference between the outlet water temperature and the inlet water temperature, it further includes: judging whether the change amount of the outlet water temperature is less than or equal to the change amount threshold; based on the change amount of the outlet water temperature being less than or equal to the change amount threshold, determining the difference between the outlet water temperature and the inlet water temperature.

[0039] In this design, when the instant heating device operates, it can be divided into two stages. The first stage is the heating-up stage, during which the outlet water temperature of the instant heating device continuously rises; the second stage is the stable outlet water stage, within this stage, the outlet water temperature of the instant heating device is within a stable range.

[0040] Particularly, before detecting the inlet water temperature and the outlet water temperature of the instant heating device, the present invention first judges whether the instant heating device is in the temperature outlet stage, and only when the instant heating device is in the stable outlet water stage, starts to detect the inlet water temperature and the outlet water temperature of the instant heating device. In this way, it can be ensured that the subsequent obtained temperature difference value is the temperature difference value in the stable outlet water stage of the instant heating device, and it can be ensured that the finally obtained heating capacity value is more accurate.

[0041] Specifically, during the process of judging whether the instant heating device is in the temperature outlet stage, the change amount of the outlet water temperature can be detected, and it is judged whether the change amount is less than the change amount threshold or equal to the change amount threshold. If the change amount of the outlet water temperature is less than the change amount threshold or equal to the change amount threshold, it indicates that the outlet water temperature of the instant heating device has been stable at this time, that is, the instant heating device is in the stable outlet water stage. Specifically, the above change amount threshold can be designed according to the actual situation, and generally the change amount threshold is relatively small.

[0042] In some possible designs, before the step of obtaining the inlet water temperature and the outlet water temperature of the instant heating device, the control method further includes: controlling the water supply component of the instant heating device to operate according to the set driving value; controlling the heating component of the instant heating device to operate according to the set heating power.

[0043] In this design, before detecting the inlet water temperature and the outlet water temperature of the instant heating device, it is necessary to control the heating component and the water supply component of the instant heating device to work. Moreover, both the heating power of the heating component and the driving power of the water supply component will directly affect the temperature difference value of the instant heating device. Therefore, before detecting the inlet water temperature and the outlet water temperature of the instant heating device, the water supply component is controlled to work according to the set driving value to ensure a certain liquid flow rate of the instant heating device; the heating component is controlled to work according to the set heating power to ensure a certain heating power of the instant heating device. In this way, the calculation accuracy of the heating value can be greatly improved. Specifically, the set driving value can be the set driving power or the set driving current.

[0044] In some possible designs, before the step of obtaining the inlet water temperature and the outlet water temperature of the instant heating device, the regulation method further includes: determining whether a regulation instruction is received; and based on the received regulation instruction, controlling the water supply component and the heating component of the instant heating device to work.

[0045] In this design, before detecting the inlet water temperature and the outlet water temperature of the instant heating device, it is first determined whether a regulation instruction is received, and this regulation instruction is used to control the opening of the regulation of the heating capacity value of the instant heating device. If the regulation instruction is received, then the inlet water temperature and the outlet water temperature of the instant heating device are detected, and subsequent calculation and determination steps are performed.

[0046] A second aspect of the present invention provides a regulation device for an instant heating device, including: an acquisition unit for acquiring the inlet water temperature and the outlet water temperature of the instant heating device; and a control unit for determining the difference between the outlet water temperature and the inlet water temperature, and taking the difference as the temperature difference value of the instant heating device, and determining the heating capacity value of the instant heating device according to the temperature difference value and the parameter value.

[0047] The regulation device for the instant heating device proposed by the present invention can calculate the heating capacity value of a single instant heating device before the entire batch of instant heating devices leave the factory, thereby ensuring that each instant heating device has an accurate heating capacity value, avoiding the errors and impacts brought by each component of the instant heating device, and ensuring that the instant heating device can accurately heat the water flow to the specified temperature during use, realizing precise control of the water temperature.

[0048] The regulation device for the instant heating device includes an acquisition unit and a control unit. Among them, the acquisition unit acquires the inlet water temperature before the instant heating device is heated and acquires the outlet water temperature after the instant heating device is heated; then, the control unit calculates the difference between the outlet water temperature and the inlet water temperature, and takes the difference between the outlet water temperature and the inlet water temperature as the temperature difference value of the instant heating device. Then, the control unit calculates the heating capacity value of this instant heating device according to the above temperature difference value and the parameter value, thereby realizing the learning process of the heating capacity value of a single instant heating device and ensuring the accuracy of the heating capacity value of a single instant heating device.

[0049] It should be noted here that the instant heating device includes a heating component and a water supply component. The above-mentioned heating capacity value refers to the heating capacity value reflected by the maximum stable temperature rise generated by the instant heating device when the heating component is driven by a fixed power supply voltage and the water supply component is driven by a fixed driving voltage. Those skilled in the art can understand the concept of the above-mentioned heating capacity value.

[0050] Therefore, the control device of the instant heating device proposed by the present invention can accurately calculate the true heating capacity value of the instant heating device, effectively solve the technical problem of inaccurate heating capacity value caused by the tolerance superposition of each component in the instant heating device, enable the instant heating device to determine the accurate heating capacity value according to its actual situation, and ensure the best performance effect and water outlet control of the instant heating device.

[0053] In addition, the instant heating device further includes a liquid supply component, a heating component, a first temperature detection component and a second temperature detection component. Among them, the liquid supply component is used to drive the liquid, the heating component is used to heat the liquid, the first temperature detection component is used to detect the water outlet temperature of the instant heating device, and the second temperature detection component is used to detect the water inlet temperature of the instant heating device.

[0071] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below in conjunction with 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 may be combined with each other.

[0072] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways than those described herein. Therefore, the scope of the present invention is not limited by the specific embodiments disclosed below.

[0073] The following will refer to Figures 1 to 7 to describe an instant heating device, a control method and a control device therefor, a water treatment device, and a medium according to some embodiments of the present invention.

[0074] A first embodiment of the present invention proposes a control method for an instant heating device. Before the whole batch of instant heating devices leave the factory, the heating capacity value of a single instant heating device can be calculated, thereby ensuring that each instant heating device has an accurate heating capacity value, avoiding the errors and impacts of various components of the instant heating device, and ensuring that the instant heating device can accurately heat the water flow to a specified temperature during use, realizing precise control of the water temperature.

[0075] As Figure 1 shown, the control method of the instant heating device includes:

[0076] Step 102, obtaining the inlet water temperature and the outlet water temperature of the instant heating device;

[0077] Step 104, determining the difference between the outlet water temperature and the inlet water temperature, and taking the difference as the temperature difference value of the instant heating device;

[0078] Step 106, determining the heating capacity value of the instant heating device according to the temperature difference value and the parameter value.

[0079] In this embodiment, first, the inlet water temperature of the instant heating device before heating is obtained, and the outlet water temperature of the instant heating device after heating is obtained; then, the difference between the outlet water temperature and the inlet water temperature is calculated, and the difference between the outlet water temperature and the inlet water temperature is taken as the temperature difference value of the instant heating device. Then, according to the above temperature difference value and the parameter value, the heating capacity value of this instant heating device is calculated, thereby realizing the learning process of the heating capacity value of a single instant heating device and ensuring the accuracy of the heating capacity value.

[0080] It should be noted here that the instant heating device includes a heating component and a water supply component. The above-mentioned heating capacity value refers to: the heating capacity value reflected by the maximum stable temperature rise generated by the instant heating device when the heating component is driven by a fixed supply voltage and the water supply component is driven by a fixed driving voltage. Those skilled in the art can understand the concept of the above-mentioned heating capacity value.

[0081] Therefore, the control method of the instant heating device proposed in this embodiment can accurately calculate the true heating capacity value of the instant heating device, effectively solve the technical problem of inaccurate heating capacity value caused by the tolerance superposition of each component in the instant heating device, enable the instant heating device to determine the accurate heating capacity value according to its actual situation, and ensure the best performance effect and water outlet control of the instant heating device.

[0082] The second embodiment of the present invention proposes a control method of an instant heating device. On the basis of the first embodiment, further:

[0083] The parameter values include the standard temperature difference value and the maximum temperature difference value. That is, the present invention can determine the heating capacity value of the heating device according to the temperature difference value of the instant heating device and the above-mentioned standard temperature difference value and maximum temperature difference value.

[0084] It can be understood that the above-mentioned standard temperature difference value is a parameter value related to the outlet water temperature and the inlet water temperature of the instant heating device, and the above-mentioned maximum temperature difference value is also a parameter value related to the outlet water temperature and the inlet water temperature of the instant heating device. The outlet water temperature and the inlet water temperature of the instant heating device also reflect the heating capacity value of the instant heating device.

[0085] In this embodiment, further, when determining the heating capacity value of the instant heating device, respectively calculate the first difference between the temperature difference value of the instant heating device and the standard temperature difference value, and the second difference between the maximum temperature difference value and the standard temperature difference value; then, determine the heating capacity value of the instant heating device according to the proportional relationship between the first difference and the second difference. Specifically, the heating capacity value of the above-mentioned instant heating device can be obtained according to the ratio between the first difference and the second difference.

[0086] In a specific embodiment, the above-mentioned temperature difference value, maximum temperature difference value and standard temperature difference value can be substituted into a preset formula, and then the heating capacity value can be calculated through the formula.

[0087] Among them, the preset formula is M = f(△T, △T 最大 , △T 标准 ); where M is the heating capacity value of the instant heating device, △T is the temperature difference value of the instant heating device, △T 最大 is the maximum temperature difference value, and △T 标准 is the standard temperature difference value.

[0088] More specifically, the preset formula is where a and b are constants. It should be noted here that the selection of a and b is for normalization processing, so those skilled in the art can select them according to their needs, and those skilled in the art can also understand this.

[0089] The third embodiment of the present invention proposes a control method of an instant heating device. On the basis of the first embodiment, further:

[0090] The parameter value can be preset in the instant heating device. Specifically, it can be preset in the main control board of the instant heating device. That is to say, when determining the heating capacity value of the instant heating device, the above-mentioned parameter value stored in advance can be directly retrieved.

[0091] In particular, the process of storing the parameter value has been completed during the design or manufacturing process of the instant heating device. Specifically, during the process of selecting the parameter value, it can be confirmed according to the tolerance combination of each component of the instant heating device.

[0092] The fourth embodiment of the present invention proposes a control method for an instant heating device. On the basis of the first embodiment, further:

[0093] The parameter value can be determined according to the parameter value of one instant heating device among multiple instant heating devices. Specifically, during the production process of the instant heating device, multiple instant heating devices will be manufactured. Therefore, in this embodiment, one of the multiple instant heating devices can be selected as the target instant heating device, and the relevant parameters of this target instant heating device can be used as the above-mentioned parameter value.

[0094] In particular, the target instant heating device can be in the same batch as the instant heating device for which the heating capacity value is to be calculated, or in a different batch from the instant heating device for which the heating capacity value is to be calculated.

[0095] The fifth embodiment of the present invention proposes a control method for an instant heating device. On the basis of the second embodiment, further:

[0096] The parameter value on which the process of determining the heating capacity value of the instant heating device in this embodiment is based is determined according to the heating power of the heating component of the instant heating device and the liquid flow rate of the water supply component of the instant heating device. In this way, during the process of calculating the heating capacity value, the heating power of the above-mentioned heating component and the liquid flow rate of the water supply component can be fully considered to ensure that the calculation result of the heating capacity value is more accurate.

[0097] In this embodiment, further, each instant heating device has a nominal power range and a nominal flow rate range. Under the same inlet water temperature, when the instant heating device works at different heating powers, the outlet water temperature will also be different; correspondingly, under the same inlet water temperature, when the instant heating device works at different liquid flow rates, the outlet water temperature will also be different.

[0098] Therefore, the process of determining the above maximum temperature difference and standard temperature difference is as follows:

[0099] First, control the heating component to operate at the nominal maximum power, while controlling the water supply component to operate at the nominal minimum flow rate. Under this state, obtain the maximum outlet water temperature of the instant heating device. Then, control the heating component to operate at the nominal minimum power, while controlling the water supply component to operate at the nominal maximum flow rate. Under this state, obtain the minimum outlet water temperature of the instant heating device.

[0100] In this way, calculate the difference between the maximum outlet water temperature and the inlet water temperature, and use this difference as the maximum temperature difference.

[0101] In this way, select any temperature value between the maximum outlet water temperature and the minimum outlet water temperature, calculate the difference between this temperature value and the inlet water temperature, and use this difference as the above-mentioned standard temperature difference value.

[0102] More specifically, the temperature value is the average of the maximum outlet water temperature and the minimum outlet water temperature. That is, in the process of calculating the standard temperature difference value, first calculate the average of the maximum outlet water temperature and the minimum outlet water temperature, then calculate the difference between this average value and the inlet water temperature, and use this difference as the above-mentioned standard temperature difference value.

[0103] The sixth embodiment of the present invention proposes a control method for an instant heating device. On the basis of the first embodiment, further:

[0104] After calculating the heating capacity value, store the calculated heating capacity for the subsequent use of the instant heating device.

[0105] In addition, after obtaining the heating capacity value of the instant heating device, the instant heating device can be controlled to operate according to this heating capacity value. Specifically, it is to control the water supply component or the heating component of the instant heating device to operate, or it can also be to control the water supply component and the heating component to operate simultaneously.

[0106] The seventh embodiment of the present invention proposes a control method for an instant heating device. On the basis of the first embodiment, further:

[0107] When the instant heating device is operating, it can be divided into two stages. The first stage is the heating-up stage, at this time the outlet water temperature of the instant heating device is continuously rising; the second stage is the stable outlet water stage, within this stage the outlet water temperature of the instant heating device is within a stable range.

[0108] Specifically, before detecting the inlet water temperature and the outlet water temperature of the instant heating device, the present invention first determines whether the instant heating device is in the temperature outlet stage, and only when the instant heating device is in the stable outlet water stage, starts to detect the inlet water temperature and the outlet water temperature of the instant heating device. In this way, it can be ensured that the subsequent obtained temperature difference value is the temperature difference value in the stable outlet water stage of the instant heating device, and it can be ensured that the finally obtained heating capacity value is more accurate.

[0109] Specifically, during the process of determining whether the instant heating device is in the temperature water outlet stage, the change amount of the water outlet temperature can be detected, and it can be determined whether the change amount is less than the change amount threshold or equal to the change amount threshold. If the change amount of the water outlet temperature is less than the change amount threshold or equal to the change amount threshold, it indicates that the water outlet temperature of the instant heating device has stabilized at this time, that is, the instant heating device is in the stable water outlet stage.

[0110] Specifically, the above change amount threshold can be designed according to the actual situation, and generally the change amount threshold is relatively small.

[0111] The eighth embodiment of the present invention proposes a control method for an instant heating device. On the basis of the first embodiment, further:

[0112] Before detecting the inlet water temperature and the outlet water temperature of the instant heating device, it is necessary to control the heating component and the water supply component of the instant heating device to work. Moreover, the heating power of the above heating component and the driving power of the above water supply component will directly affect the temperature difference value of the instant heating device.

[0113] Therefore, before detecting the inlet water temperature and the outlet water temperature of the instant heating device, the water supply component is controlled to work according to the set driving value to ensure a certain liquid flow rate of the instant heating device; the heating component is controlled to work according to the set heating power to ensure a certain heating power of the instant heating device. In this way, the calculation accuracy of the heating value can be greatly improved.

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

[0115] Before detecting the inlet water temperature and the outlet water temperature of the instant heating device, first determine whether a control command is received, and this control command is used to control the start of regulating the heating capacity value of the instant heating device. If the control command is received, then detect the inlet water temperature and the outlet water temperature of the instant heating device, and perform subsequent calculation and determination steps.

[0116] As Figure 2 shown, the tenth embodiment of the present invention proposes a control device 200 for an instant heating device, which can calculate the heating capacity value of a single instant heating device before the whole batch of instant heating devices leave the factory, thereby ensuring that each instant heating device has an accurate heating capacity value, avoiding the errors and influences of each component of the instant heating device, and ensuring that the instant heating device can accurately heat the water flow to the specified temperature during use, and realizing precise control of the water temperature.

[0117] The control device 200 of the instant heating device includes an acquisition unit 202 and a control unit 204. Among them, the acquisition unit 202 acquires the inlet water temperature before the instant heating device starts heating and the outlet water temperature after the instant heating device finishes heating. Then, the control unit 204 calculates the difference between the outlet water temperature and the inlet water temperature, and regards the difference between the outlet water temperature and the inlet water temperature as the temperature difference value of the instant heating device. Then, the control unit 204 calculates the heating capacity value of this instant heating device according to the above temperature difference value parameter, thereby realizing the learning process of the heating capacity value of a single instant heating device and ensuring the accuracy of the heating capacity value.

[0118] Therefore, the control device 200 of the instant heating device proposed by the present invention can accurately calculate the true heating capacity value of the instant heating device, effectively solve the technical problem of inaccurate heating capacity value caused by the superposition of tolerances of each component in the instant heating device, enable the instant heating device to determine the accurate heating capacity value according to its actual situation, and ensure the best performance effect and outlet water control of the instant heating device.

[0119] The eleventh embodiment of the present invention proposes a control device 200 of an instant heating device. On the basis of the tenth embodiment, further:

[0120] The parameter values include a temperature difference standard value and a maximum temperature difference value. That is to say, the present invention can determine the heating capacity value of the heating device according to the temperature difference value of the instant heating device and the above temperature difference standard value and maximum temperature difference value.

[0121] It can be understood that the above temperature difference standard value is a parameter value related to the outlet water temperature and the inlet water temperature of the instant heating device, and the above maximum temperature difference value is also a parameter value related to the outlet water temperature and the inlet water temperature of the instant heating device. The outlet water temperature and the inlet water temperature of the instant heating device also reflect the heating capacity value of the instant heating device.

[0122] In this embodiment, further, when determining the heating capacity value of the instant heating device, the first difference between the temperature difference value of the instant heating device and the temperature difference standard value and the second difference between the maximum temperature difference value and the temperature difference standard value are calculated respectively. Then, the heating capacity value of the instant heating device is determined according to the proportional relationship between the first difference and the second difference. Specifically, the heating capacity value of the above instant heating device can be obtained according to the ratio between the first difference and the second difference.

[0123] In a specific embodiment, the above temperature difference value, maximum temperature difference value and temperature difference standard value can be substituted into a preset formula, and then the heating capacity value is calculated through the formula.

[0124] Among them, the preset formula is M = f(△T, △T 最大 , △T 标准 ); where M is the heating capacity value of the instant heating device, △T is the temperature difference value of the instant heating device, △T最大 is the maximum temperature difference, △T 标准 is the standard value of the temperature difference.

[0125] More specifically, the preset formula is where a and b are constants. It should be noted here that the selection of a and b lies in the normalization process, so those skilled in the art can select them according to needs, and those skilled in the art can also understand this.

[0126] The twelfth embodiment of the present invention proposes a control device 200 for an instant heating device. On the basis of the tenth embodiment, further:

[0127] The parameter value can be preset in the instant heating device. Specifically, it can be preset in the main control board of the instant heating device. That is to say, when determining the heating capacity value of the instant heating device, the above-mentioned parameter value stored in advance can be directly retrieved.

[0128] The process of storing the parameter value has been completed during the design or manufacturing process of the instant heating device. Specifically, during the process of selecting the parameter value, it can be confirmed according to the tolerance combination of each component of the instant heating device.

[0129] The thirteenth embodiment of the present invention proposes a control device 200 for an instant heating device. On the basis of the tenth embodiment, further:

[0130] The parameter value can be determined according to the parameter value of one instant heating device among multiple instant heating devices. Specifically, during the production process of the instant heating device, multiple instant heating devices will be manufactured. Therefore, the present invention can select one of the multiple instant heating devices and select the relevant parameters of this instant heating device as the above-mentioned parameter value.

[0131] In particular, the instant heating device can be in the same batch as the instant heating device for which the heating capacity value is to be calculated, or can be in a different batch from the instant heating device for which the heating capacity value is to be calculated.

[0132] The fourteenth embodiment of the present invention proposes a control device 200 for an instant heating device. On the basis of the tenth embodiment, further:

[0133] The instant heating capacity value calculated by the present invention directly depends on the heating power of the heating component in the instant heating device and the liquid flow rate of the water supply component in the instant heating device. Specifically, the greater the heating power of the heating component, the greater the heating capacity value of the instant heating device; the greater the liquid flow rate of the water supply component, the smaller the heating capacity value of the instant heating device.

[0134] Therefore, the parameter values based on which the heating capacity value of the instant heating device is determined in this embodiment are determined according to the heating power of the heating component of the instant heating device and the liquid flow rate of the water supply component of the instant heating device. In this way, during the calculation of the heating capacity value, the heating power of the above-mentioned heating component and the liquid flow rate of the water supply component can be fully considered to ensure that the calculation result of the heating capacity value is more accurate.

[0135] In this embodiment, further, each instant heating device has a nominal power range and a nominal flow rate range. When the inlet water temperature is the same, if the instant heating device operates at different heating powers, the outlet water temperature will also be different; correspondingly, when the inlet water temperature is the same, if the instant heating device operates at different liquid flow rates, the outlet water temperature will also be different.

[0136] Therefore, the determination process of the above maximum temperature difference and standard temperature difference is as follows:

[0137] First, control the heating component to operate at the nominal maximum power, and at the same time control the water supply component to operate at the nominal minimum flow rate, and obtain the maximum outlet water temperature of the instant heating device in this state; then, control the heating component to operate at the nominal minimum power, and at the same time control the water supply component to operate at the nominal maximum flow rate, and obtain the minimum outlet water temperature of the instant heating device in this state.

[0138] In this way, calculate the difference between the maximum outlet water temperature and the inlet water temperature, and use this difference as the maximum temperature difference.

[0139] In this way, select any temperature value between the maximum outlet water temperature and the minimum outlet water temperature, calculate the difference between this temperature value and the inlet water temperature, and use this difference as the above standard temperature difference.

[0140] More specifically, the temperature value is the average of the maximum outlet water temperature and the minimum outlet water temperature. That is, during the calculation of the standard temperature difference, first calculate the average of the maximum outlet water temperature and the minimum outlet water temperature, and then calculate the difference between this average value and the inlet water temperature, and use this difference as the above standard temperature difference.

[0141] The fifteenth embodiment of the present invention proposes a control device 200 for an instant heating device. On the basis of the tenth embodiment, further:

[0142] The control unit 204 is further configured to store the heating capacity value; and control the driving values of the water supply component and / or the heating component of the instant heating device according to the heating capacity value.

[0143] In this embodiment, after the control unit 204 calculates the heating capacity value, the calculated heating capacity is stored for the subsequent use of the instant heating device. In addition, after obtaining the heating capacity value of the instant heating device, the control unit 204 can control the instant heating device to work according to the heating capacity value. Specifically, the control unit 204 controls the water supply component or the heating component of the instant heating device to work, or the control unit 204 controls the water supply component and the heating component to work simultaneously.

[0144] The sixteenth embodiment of the present invention provides a control device 200 for an instant heating device. On the basis of the tenth embodiment, further:

[0145] The acquisition unit 202 is further configured to determine whether the change amount of the outlet water temperature is less than or equal to the change amount threshold; based on the change amount of the outlet water temperature being less than or equal to the change amount threshold, determine the difference between the outlet water temperature and the inlet water temperature.

[0146] In this embodiment, when the instant heating device works, it can be divided into two stages. The first stage is the heating-up stage, during which the outlet water temperature of the instant heating device continuously rises; the second stage is the stable outlet water stage, in which the outlet water temperature of the instant heating device is within a stable range.

[0147] Specifically, before detecting the inlet water temperature and the outlet water temperature of the instant heating device, the present invention first determines whether the instant heating device is in the temperature outlet stage, and when the instant heating device is in the stable outlet water stage, it starts to detect the inlet water temperature and the outlet water temperature of the instant heating device. In this way, it can be ensured that the subsequent obtained temperature difference value is the temperature difference value in the stable outlet water stage of the instant heating device, and it can be ensured that the finally obtained heating capacity value is more accurate.

[0148] Specifically, during the process of determining whether the instant heating device is in the temperature outlet stage, the change amount of the outlet water temperature can be detected, and it is determined whether the change amount is less than the change amount threshold or equal to the change amount threshold. If the change amount of the outlet water temperature is less than the change amount threshold or equal to the change amount threshold, it means that the outlet water temperature of the instant heating device is stable at this time, that is, the instant heating device is in the stable outlet water stage. Specifically, the above change amount threshold can be designed according to the actual situation, and generally the change amount threshold is small.

[0149] The seventeenth embodiment of the present invention provides a control device 200 for an instant heating device. On the basis of the tenth embodiment, further:

[0150] The control unit 204 is further configured to control the water supply component of the instant heating device to work according to the set driving value; and control the heating component of the instant heating device to work according to the set heating power.

[0151] In this embodiment, before detecting the inlet water temperature and the outlet water temperature of the instant heating device, it is necessary to control the heating component and the water supply component of the instant heating device to work. Moreover, both the heating power of the heating component and the driving power of the water supply component will directly affect the temperature difference value of the instant heating device. Therefore, before detecting the inlet water temperature and the outlet water temperature of the instant heating device, the present invention controls the water supply component to work according to a set driving value to ensure a certain liquid flow rate of the instant heating device; controls the heating component to work according to a set heating power to ensure a certain heating power of the instant heating device. In this way, the calculation accuracy of the heating value can be greatly improved.

[0152] The eighteenth embodiment of the present invention proposes a control device 200 for an instant heating device. On the basis of the tenth embodiment, further:

[0153] The control unit 204 is further configured to determine whether a control instruction is received; based on the received control instruction, control the water supply component and the heating component of the instant heating device to work.

[0154] In this embodiment, before detecting the inlet water temperature and the outlet water temperature of the instant heating device, first determine whether a control instruction is received. The control instruction is used to control the opening of the regulation of the heating capacity value of the instant heating device. If the control instruction is received, then detect the inlet water temperature and the outlet water temperature of the instant heating device, and perform subsequent calculation and determination steps.

[0155] As Figure 4 、 Figure 5 、 Figure 6 and Figure 7 shown, the nineteenth embodiment of the present invention proposes an instant heating device, including the control device for the instant heating device as described in the above embodiment.

[0156] Therefore, the instant heating device proposed in this embodiment has all the beneficial effects of the above-mentioned control device for the instant heating device, and will not be elaborated one by one here.

[0157] In addition, the instant heating device further includes a liquid supply component 406, a heating component 402, a first temperature detection component 404, and a second temperature detection component 408. Among them, the liquid supply component 406 is used to drive the liquid, the heating component 402 is used to heat the liquid, the first temperature detection component 404 is used to detect the outlet water temperature of the instant heating device, and the second temperature detection component 408 is used to detect the inlet water temperature of the instant heating device.

[0158] 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 hot water reserve work such as long-term 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. Low cost. Since there is no need for a water storage heat filling and related heating detection components 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. The temperature control unit and the volume calculation unit inside the instant heating device can quickly and accurately reach the target temperature by heating and adjusting the water flow rate, meeting the user's water outlet requirements.

[0159] In a specific embodiment, the first temperature detection component 404 may adopt an NTC temperature sensor (Negative Temperature Coefficient Sensor, whose resistance decreases as the temperature increases).

[0160] In a specific embodiment, the second temperature detection component 408 may adopt an NTC temperature sensor (Negative Temperature Coefficient Sensor, whose resistance decreases as the temperature increases).

[0161] The twentieth embodiment of the present invention proposes a water treatment device (not shown in the figure), including the instant heating device as described in the above embodiment.

[0162] 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 instant heating device, and will not be elaborated one by one here.

[0163] In this embodiment, further, the water treatment device includes, but is not limited to, water heaters, water dispensers, and water purifiers. They will not be listed one by one here.

[0164] The twenty-first 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.

[0165] When the program stored on the readable storage medium is executed, the steps of the regulation method as described in any of the above embodiments can be realized. Therefore, it has all the beneficial effects of the above regulation method, and will not be elaborated one by one here.

[0166] In a specific embodiment, the regulation method of the instant heating device proposed by the present invention can identify the comprehensive tolerance of different instant heating devices and learn with the heating capacity value as the dimension. Among them, the heating capacity value refers to: the heating capacity value reflected by the maximum stable temperature rise generated by the instant heating device when the heating component is driven by a fixed supply voltage and the water supply component is driven by a fixed driving voltage. Those skilled in the art can understand the concept of the above heating capacity value.

[0167] In addition, regarding the tolerance combinations of the various components of the instant heating device, what the regulation method is most concerned about is the heating capacity performance after the tolerances of the various components of the instant heating device are superimposed, that is, under the same driving force output, the strength of the heating capacity of the instant heating device. The regulation method can execute a more conservative or more radical temperature control strategy according to the heating strength of different instant heating devices. Under actual development and testing, satisfactory results can be obtained.

[0168] Specifically, after the instant heating device is produced in the present invention, a single-unit self-learning on the production line can be carried out. The operation steps are as follows:

[0169] Step 1: The instant heating device is put on the line, the communication port of the calibration device and other detection ports are connected, the standard water inlet and outlet pipelines are connected, and power is supplied at a fixed voltage (such as AC 220V). The calibration device issues an instruction for the water supply component to start working, and the system enters the water circulation; when the water circuit system is full of water, the water outlet stops.

[0170] Step 2: The calibration device issues a regulation instruction. After the instant heating device receives this regulation instruction, it automatically outputs a set driving value to the water supply component, and at the same time drives the heating component with a set heating power, and the instant heating device starts to output hot water.

[0171] Step 3: When it is detected by the first temperature detection component that the outlet water temperature has stabilized and the fluctuation is very small, the temperature difference value △T at this time is calculated, that is, the outlet water temperature T 出水 and the inlet water temperature T 进水 difference:

[0172] △T = T 出水 - T 进水 ;

[0173] Step 4: Substitute △T into the preset formula to calculate the heating capacity value of the instant heating device:

[0174]

[0175] where M is the heating capacity value of the instant heating device, △T is the temperature difference value of the instant heating device, △T 最大 is the maximum temperature difference, △T 标准 is the standard temperature difference value, and a and b are constants and are self-selected according to normalization processing. For example: taking a = 128 and b = 127, the value range of M can be realized from 0 to 255.

[0176] Step 5: The main control board of the instant heating device writes the heating capacity value M obtained in the above step 4 into the EEPROM on the main control board, so that this data will not be lost even after power failure. Then stop the water outlet, cut off the power and take off the line, and the production line self-learning is completed and ended. Of course, the heating capacity value M can also be stored in other memories, such as ROM, RAM, etc.

[0177] As Figure 3 shown below, a specific embodiment is used to illustrate the control method of the instant heating device proposed by the present invention. As Figure 3 shown, the control method of the instant heating device includes:

[0178] Step 302: The instant heating device goes online, connects the pipeline and the calibration device, and discharges water to flush the pipeline;

[0179] Step 304: The calibration device sends a control instruction to control the water supply component to work according to the set driving value and control the heating component to work according to the set heating power;

[0180] Step 306: Determine whether the outlet water temperature has stabilized. If the determination result is yes, execute Step 308; otherwise, continue to determine;

[0181] Step 308: Obtain the temperature difference value of the instant heating device at this time. The temperature difference value is equal to the difference between the outlet water temperature and the inlet water temperature;

[0182] Step 310: Substitute the obtained difference value into the formula to obtain the heating capacity value of the instant heating device;

[0183] Step 312: Store the heating capacity value in the EEPROM on the main control board of the instant heating device.
