Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical equipment, in particular to a boiled water machine, a control method and device of the boiled water machine and a computer device. BACKGROUND

[0002] With the improvement of living standards, the performance of the pure drinking machine is constantly improved. The boiled water machine, as a new darling of the industry, is mainly capable of quickly providing different temperature boiled water, and is deeply favored by the majority of consumers. The boiled water machine can provide different temperature boiled water. Essentially, the raw water is first boiled and then cooled to the set temperature. The cooling is achieved by relying on the heat exchanger. In order to achieve the effect of rapid cooling, while taking into account the appearance requirement of small volume of the whole machine, the heat exchange flow channel is usually designed as W type. If the water pump stops pumping water, the water in the heating body gathers at the bottom of the heat exchanger under the action of gravity, and cannot be discharged from the water outlet nozzle in time. Long-term non-use is easy to produce dead water, and the next time the boiled water mode is started, the initial water outlet temperature of the boiled water machine will be lower than the set water outlet temperature, which will cause poor user experience. SUMMARY

[0003] Therefore, the present application provides a boiled water machine, a control method and device of the boiled water machine and a computer device to solve the problem of low initial water outlet temperature of the boiled water machine due to the existence of cold water in the heat exchanger of the boiled water machine.

[0004] In a first aspect, the present application provides a control method of a boiled water machine, comprising the following steps: obtaining a first temperature of a heating body at the current time when the boiled water operation stops; obtaining a first threshold value, wherein the first threshold value is determined according to the action temperature of a temperature limiter; determining the extension heating mode of the boiled water machine according to the size relationship between the first temperature and the first threshold value; and controlling the boiled water machine to perform extension heating according to the determined extension heating mode.

[0005] The control method of the boiled water machine provided by the present application can obtain the first temperature of the heating body at the current time when the boiled water operation stops and the first threshold value, determine the extension heating mode of the boiled water machine according to the size relationship between the first temperature and the first threshold value, and further control the boiled water machine to perform extension heating according to the determined extension heating mode. The extension heating after the boiled water operation stops makes the energy generated by the heating body unable to be taken away by the water flow, causing the water vapor in the heating body to vaporize, and the water vapor is discharged through the heat exchange flow channel to push the residual water in the heat exchange flow channel to flow out to the water outlet nozzle, so that the heat exchange flow channel is emptied, thereby solving the problem that the initial water outlet temperature of the boiled water machine is lower than the set water outlet temperature due to the existence of cold water in the heat exchanger of the boiled water machine, and the extension heating will not cause the temperature limiter to act.

[0006] In an alternative embodiment, the determining the extension heating mode of the water feeding machine according to the magnitude relationship between the first temperature and the first threshold value comprises: determining whether the first temperature is less than a preset first threshold value; when the first temperature is less than the first threshold value, taking the full dry burning mode as the extension heating mode of the water feeding machine; and when the first temperature is greater than or equal to the first threshold value, taking the half dry burning mode as the extension heating mode of the water feeding machine.

[0007] That is, when the first temperature is low (the first temperature is less than the first threshold value), the extension heating adopts the full dry burning mode, and since the actual temperature of the heating device is relatively low at this time, the extension heating even in the full dry burning mode will not cause the action of the temperature limiter. When the first temperature is high (the first temperature is greater than or equal to the first threshold value), the extension heating adopts the half dry burning mode, and since the actual temperature of the heating device is relatively high at this time, in order not to cause the action of the temperature limiter, the extension heating needs to adopt the half dry burning mode.

[0008] In an alternative embodiment, the controlling the water feeding machine to perform the extension heating according to the determined extension heating mode comprises: when the extension heating mode is the full dry burning mode, controlling the water pump to stop pumping water but the heating body to continue heating; obtaining a second temperature of the heating body at the current time; determining whether the second temperature is less than the first threshold value; when the second temperature is less than the first threshold value, returning to the step of controlling the water pump to stop pumping water but the heating body to continue heating; and when the second temperature is greater than or equal to the first threshold value, controlling the heating body to stop heating.

[0009] That is, when the first temperature is low (the first temperature is less than the first threshold value) and the extension heating adopts the full dry burning mode, whether to exit the extension heating is determined by judging whether the actual temperature of the heating device is greater than or equal to the first threshold value.

[0010] In an alternative embodiment, the controlling the water feeding machine to perform the extension heating according to the determined extension heating mode comprises: when the extension heating mode is the half dry burning mode, controlling the water pump to pump water at a preset flow rate and the heating body to continue heating; obtaining an actual duration of the half dry burning mode; determining whether the actual duration reaches a preset second threshold value; and when the actual duration reaches the second threshold value, controlling the water pump to stop pumping water and the heating body to stop heating.

[0011] That is, when the first temperature is high (the first temperature is greater than or equal to the first threshold value) and the extension heating adopts the half dry burning mode, whether to exit the extension heating is determined by judging whether the actual duration of the heating of the heating device reaches the second threshold value.

[0012] In an alternative embodiment, before the step of obtaining the first temperature of the heating body at the current time, the method further comprises the following steps: obtaining an actual water taking duration of the water taking operation; determining whether the actual water taking duration is greater than a preset third threshold value; and when the actual water taking duration is greater than the third threshold value, performing the step of obtaining the first temperature of the heating body at the current time.

[0013] That is, only when the water taking volume exceeds the fourth threshold (equivalent to the actual water taking duration being greater than the third threshold), the extended heating is performed after the water taking is finished. This is because, if the user continuously operates water taking, water stopping, water taking, and so on, and the extended heating is performed after each water taking is finished, the heat will continuously accumulate, leading to dry burning of the heating body, affecting the service life of the whole machine, or abnormal tripping of the temperature limiter. The present application only performs the extended heating after the water taking is finished when the actual water taking duration exceeds the third threshold, so that even if the water taking is frequent, dry burning of the heating body inside will not occur.

[0014] In an optional embodiment, before the actual water taking duration of the boiled water taking operation is obtained, the following step is further included: obtaining a water taking mode of the boiled water taking operation; when the water taking mode is the non-quantitative water taking, the step of obtaining the actual water taking duration of the boiled water taking operation is performed.

[0015] That is, when the water taking mode is the non-quantitative water taking, it is necessary to determine whether the actual water taking volume exceeds the preset fourth threshold through the actual water taking duration. When the water taking mode is the quantitative water taking, because the actual water taking volume of the quantitative water taking is generally large and exceeds the preset fourth threshold, it is not necessary to determine whether the actual water taking volume of the quantitative water taking exceeds the preset fourth threshold.

[0016] In a second aspect, the present application further provides a control device of a boiled water machine, which comprises a first obtaining module, a second obtaining module, an extended heating mode determining module, and an extended heating control module; the first obtaining module is used for obtaining a first temperature of the heating body at the current time when the boiled water taking operation is stopped; the second obtaining module is used for obtaining a preset first threshold, wherein the first threshold is determined according to the action temperature of the temperature limiter; the extended heating mode determining module is used for determining the extended heating mode of the boiled water machine according to the size relationship between the first temperature and the first threshold; and the extended heating control module is used for controlling the boiled water machine to perform the extended heating according to the determined extended heating mode.

[0017] In a third aspect, the present application further provides a computer device, which comprises a memory and a processor, the memory and the processor are communicatively connected with each other, the memory stores computer instructions, and the processor executes the computer instructions, thereby executing the control device of the boiled water machine of the first aspect or any of the corresponding embodiments thereof.

[0018] In a fourth aspect, the present application further provides a boiled water machine, which comprises the computer device of the third aspect.

[0019] In a fifth aspect, the present application further provides a computer readable storage medium, which stores computer instructions, and the computer instructions are used for causing a computer to execute the control device of the boiled water machine of the first aspect or any of the corresponding embodiments thereof.

[0020] In a sixth aspect, the present application further provides a computer program product comprising computer instructions for causing a computer to execute the control device of the water boiler according to the first aspect or any of its possible implementation forms.

[0021] The water boiler, the control method and device of the water boiler and the computer equipment provided by the present application have the following beneficial effects:

[0022] (1) When the taking hot water operation is stopped, the first temperature of the heating body at the current time and the preset first threshold value are obtained, and the extension heating mode of the water boiler is determined according to the size relationship between the first temperature and the first threshold value. The water boiler is further controlled to perform extension heating according to the determined extension heating mode. The extension heating after the taking hot water operation is stopped makes the energy generated by the heating body unable to be taken away by the water flow, so that the water vapor is generated by the water vaporization in the heating body, the water vapor is discharged through the heat exchange flow channel, so as to push the residual water in the heat exchange flow channel to flow out to the water outlet nozzle, so that the heat exchange flow channel is emptied, thereby solving the problem that the initial water outlet temperature of the water boiler is lower than the set water outlet temperature due to the existence of cold water in the heat exchanger of the water boiler, and the extension heating does not cause the action of the temperature limiter.

[0023] (2) The extension heating is only performed after the taking water is completed when the water volume exceeds the fourth threshold value (equivalent to the actual taking water time being longer than the third threshold value). This is because, if the user continuously operates taking water, stopping water, taking water, and the extension heating is performed after each taking water is completed, the heat will continuously accumulate, which causes the heating body to dry and burn, affecting the service life of the whole machine or causing the temperature limiter to abnormally trip. The present application only performs the extension heating after the taking water is completed when the actual taking water time exceeds the third threshold value, so that the heating body does not generate dry and burn abnormality even if the taking water is frequent. Further, when the taking water mode is the non-quantitative taking water, the actual taking water volume needs to be determined by the actual taking water time to determine whether the actual taking water volume exceeds the preset fourth threshold value. When the taking water mode is the quantitative taking water, because the actual taking water volume of the quantitative taking water is generally large and exceeds the preset fourth threshold value, it is not necessary to determine whether the actual taking water volume exceeds the preset fourth threshold value.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] According to an embodiment of the present invention, a control method for a boiled water purifier is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0032] This embodiment provides a control method for a boiled water machine, which can be used in the aforementioned computer equipment. In this embodiment, the boiled water machine is a boiled water machine using rare-earth thick-film heating. This is because the power density of conventional heating wires and quartz tubes is only 20W / cm². 2 Within this range, the power density of such heating elements is very high, reaching up to 70W / cm². 2 If dry burning occurs, the heating rate can reach 80℃ / s, posing a fire hazard. Therefore, dry burning of heating elements for such materials is strictly prohibited.

[0033] Figure 1 This is a flowchart of a water purifier control method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0034] Step S101: When the boiling water extraction operation stops, obtain the first temperature of the heating element at the current moment.

[0035] Specifically, a temperature sensor can be installed in the heating element to obtain the current temperature of the heating element.

[0036] Step S102: Obtain a preset first threshold, wherein the first threshold is determined based on the operating temperature of the temperature limiter.

[0037] All heating products on the market are equipped with a temperature limiter to meet safety standards. Specifically, the operating temperature of the temperature limiter can be determined by the following method: the whole machine is run at 1.15 times the rated power to a steady state, and the stable temperature T1 at the temperature limiter position on the surface of the heating element is measured. Then, the temperature T2 at the temperature limiter position under abnormal extreme conditions is measured. The operating temperature TS of the temperature limiter can be selected between T1 and T2.

[0038] Specifically, the first threshold is less than the operating temperature TS of the temperature limiter.

[0039] Step S103: Determine the extended heating mode of the water purifier based on the relationship between the first temperature and the first threshold.

[0040] Specifically, extended heating modes include full dry-burning mode and semi-dry-burning mode. As with all heating products on the market, in order to meet safety standards, they are equipped with a temperature limiter. During extended heating, it is also necessary to prevent the temperature limiter from activating. Therefore, it is necessary to determine whether to use full dry-burning mode or semi-dry-burning mode for extended heating based on the current first temperature and first threshold of the heating element.

[0041] Step S104: Control the water purifier to perform extended heating according to the determined extended heating mode.

[0042] The control method for the boiled water dispenser provided in this embodiment, when the boiled water dispensing operation stops, obtains the first temperature of the heating element at the current moment and a preset first threshold. Based on the relationship between the first temperature and the first threshold, the extended heating mode of the boiled water dispenser is determined. Furthermore, the boiled water dispenser is controlled to perform extended heating according to the determined extended heating mode. The extended heating after the boiled water dispensing operation stops prevents the energy generated by the heating element from being carried away by the water flow, causing the water inside the heating element to vaporize and generate water vapor. The water vapor is discharged through the heat exchange channel, thereby pushing the residual water inside the heat exchange channel to flow out to the water outlet, thus emptying the heat exchange channel. This solves the problem that the initial outlet water temperature of the boiled water dispenser is lower than the set outlet water temperature due to the presence of cold water in the heat exchanger of the boiled water dispenser. Moreover, the extended heating will not cause the temperature limiter to activate.

[0043] This embodiment provides a control method for a boiled water machine, which can be used in the aforementioned computer equipment. Figure 2 This is a flowchart of another water purifier control method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:

[0044] Step S201: When the boiling water extraction operation stops, obtain the first temperature of the heating element at the current moment.

[0045] Step S202: Obtain a preset first threshold, wherein the first threshold is determined based on the operating temperature of the temperature limiter.

[0046] In one optional implementation, the first threshold can be the operating temperature TS of the thermostat minus a temperature value, for example, the first threshold is equal to the operating temperature TS of the thermostat minus 10°C. Step S203: Determine the extended heating mode of the hot water machine based on the relationship between the first temperature and the first threshold.

[0047] In one optional implementation, determining the extended heating mode of the water conveyor based on the relationship between the first temperature and the first threshold includes the following steps S2031 to S2033.

[0048] Step S2031: Determine whether the first temperature is less than the preset first threshold.

[0049] Step S2032: When the first temperature is less than the first threshold, the dry-burning mode is used as the extended heating mode of the hot water machine.

[0050] Step S2033: When the first temperature is greater than or equal to the first threshold, the semi-dry burning mode is used as the extended heating mode of the hot water machine.

[0051] In other words, when the first temperature is low (the first temperature is less than the first threshold), the extended heating uses a fully dry-burning method. Since the actual temperature of the heating element is relatively low at this time, the extended heating will not trigger the temperature limiter even if it uses a fully dry-burning method. When the first temperature is high (the first temperature is greater than or equal to the first threshold), the extended heating uses a semi-dry-burning method. Since the actual temperature of the heating element is relatively high at this time, in order to avoid triggering the temperature limiter, the extended heating needs to use a semi-dry-burning method.

[0052] Among them, the fully dry-burning method is that the water pump stops pumping water but the heating element continues to heat; the semi-dry-burning method is that the water pump pumps water according to the preset flow rate and the heating element continues to heat.

[0053] Step S204: Control the water purifier to perform extended heating according to the determined extended heating mode.

[0054] In one optional implementation, controlling the water purifier to perform extended heating according to the determined extended heating mode includes the following steps Sa1 to Sa5.

[0055] Step Sa1: When the extended heating mode is set to full dry-burning mode, the water pump stops pumping water, but the heating element continues to heat.

[0056] In one alternative implementation, the heater is controlled to heat at full power.

[0057] Step Sa2: Obtain the second temperature of the heating element at the current moment.

[0058] Step Sa3: Determine whether the second temperature is less than the first threshold. If the second temperature is less than the first threshold, return to step Sa2; otherwise, proceed to step Sa4.

[0059] Step Sa4: Control the heating element to stop heating.

[0060] In other words, when the first temperature is low (the first temperature is less than the first threshold) and the extended heating is carried out using the full dry-burning method, the decision to stop the extended heating is made by judging whether the actual temperature of the heater is greater than or equal to the first threshold.

[0061] In another alternative implementation, controlling the water purifier to perform extended heating according to the determined extended heating mode includes the following steps Sb1 to Sb4.

[0062] Step Sb1: When the extended heating mode is semi-dry burning mode, control the water pump to pump water according to the preset flow rate and the heating element continues to heat.

[0063] In one alternative implementation, the heater is controlled to heat at full power, and the water pump draws water at a minimum flow rate, for example, at a minimum flow rate of 300 ml / min.

[0064] Step Sb2: Obtain the actual duration of the semi-dry burning mode.

[0065] Step Sb3: Determine whether the actual duration has reached the preset second threshold; if the actual duration has reached the second threshold, proceed to step Sb4; otherwise, return to step Sb2.

[0066] The second threshold can be predetermined and set in the computer equipment. The method for determining the second threshold includes: testing the full power of the whole machine's heating element and the time it takes to empty the residual water inside the heat exchanger when the water pump is pumping water at the minimum flow rate, and determining the second threshold based on the test duration.

[0067] Step Sb4: Control the water pump to stop pumping water and the heating element to stop heating.

[0068] In other words, when the first temperature is high (the first temperature is greater than or equal to the first threshold) and the extended heating is carried out in a semi-dry-burning manner, the decision to stop the extended heating is made by judging whether the actual heating duration of the heater reaches the second threshold.

[0069] This embodiment provides an extended heating control logic for use in a boiled water dispenser. After the customer stops dispensing boiled water, the internal program defaults to running the heating element at full power for a certain period, while the self-priming pump either stops or operates at a specific flow rate. This utilizes the rapid heating of the heating element to generate superheated steam, which pushes residual water from the heat exchange channel out to the outlet. After this extended heating operation, the entire heat exchange channel is essentially emptied, effectively solving the problems of stagnant water storage and the industry-wide issue of low initial water temperature.

[0070] This embodiment provides a control method for a boiled water machine, which can be used in the aforementioned computer equipment. Figure 3 This is a flowchart of another water purifier control method according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps:

[0071] Step S301: Obtain the water intake mode for the boiled water intake operation.

[0072] Specifically, the water dispensing modes include quantitative water dispensing and variable water dispensing. Quantitative water dispensing is usually divided into dispensing volumes of 180ml, 300ml, 400ml, or larger volumes; variable water dispensing is initiated by the user pressing a water dispensing button, and the dispensing stops when the button is pressed again, with the total dispensing volume being uncertain.

[0073] Step S302: Determine whether the water intake mode is variable water intake. If the water intake mode is variable water intake, proceed to step S303; if the water intake mode is variable water intake, proceed to step S305.

[0074] Step S303: Obtain the actual water collection time of the boiled water collection operation.

[0075] Step S304: Determine whether the actual water collection time is greater than the preset third threshold; if the actual water collection time is greater than the third threshold, proceed to step S305; otherwise, return to step S303.

[0076] It should be noted that if the actual water collection time no longer increases, and the longest actual water collection time is still less than the third threshold, no action will be taken.

[0077] The third threshold can be predetermined and set in the computer equipment. Specifically, the method for determining the third threshold includes: calculating the water volume inside the heating element based on its structural parameters; and calculating the shortest water addition time, i.e., the third threshold, based on the water volume inside the heating element and the minimum flow rate of the water dispenser. For example, if the diameter of the heating tube in the heating element is 20mm, the diameter of the water column inside the heating tube is 10mm, and the length of the heating tube is 95mm, then the water volume inside the heating element = 9.5 × 3.14(2-1) = 29.83ml. Further, assuming the minimum flow rate of the water pump is 300ml / min, and considering that repeated dry burning may occur when frequently adding water, it is necessary to ensure that the heating element is full of water each time the heating is extended. Therefore, the third threshold is required to be equal to 29.83 × 60 ÷ 300, i.e., 6 seconds.

[0078] In other words, when the water dispensing mode is non-quantitative, it is necessary to determine whether the actual water volume exceeds the preset fourth threshold (e.g., 29.83 ml as mentioned above) based on the actual water dispensing time. When the water dispensing mode is quantitative, since the actual volume of quantitative water dispensing is generally larger and usually exceeds the preset fourth threshold, it is not necessary to determine whether the actual water volume exceeds the preset fourth threshold.

[0079] In this embodiment, extended heating is only performed after water dispensing ends when the water volume exceeds the fourth threshold (equivalent to the actual water dispensing time exceeding the third threshold). This is because if the user continuously operates the system to dispense water, stop water supply, dispense water again, etc., and extends heating after each dispensing, heat will continuously accumulate, causing the heating element to burn out and affecting the overall lifespan of the machine, or causing the temperature limiter to trip abnormally. Extended heating is only performed after water dispensing ends when the actual water dispensing time exceeds the third threshold, thus preventing the heating element from burning out even with frequent water dispensing.

[0080] Step S305: Obtain the first temperature of the heating element at the current moment.

[0081] Step S306: Obtain a preset first threshold, wherein the first threshold is determined based on the operating temperature of the temperature limiter.

[0082] Step S307: Determine the extended heating mode of the boiled water machine based on the relationship between the first temperature and the first threshold.

[0083] Step S308: Control the water purifier to perform extended heating according to the determined extended heating mode.

[0084] The control method for the boiled water dispenser provided in this embodiment extends the heating after the boiled water dispensing operation stops, preventing the energy generated by the heating element from being carried away by the water flow. This causes the water inside the heating element to vaporize and generate steam. The steam is discharged through the heat exchange channel, which pushes the residual water inside the heat exchange channel to the water outlet, thus emptying the heat exchange channel. This solves the problem that the initial outlet water temperature of the boiled water dispenser is lower than the set outlet water temperature due to the presence of cold water in the heat exchanger. Furthermore, the extended heating does not trigger the temperature limiter. Moreover, the extended heating is only performed after the water dispensing is completed when the actual water dispensing time exceeds the third threshold. Therefore, even with frequent water dispensing, the heating element will not experience dry burning.

[0085] This embodiment also provides a control device for a boiled water machine, which is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0086] This embodiment provides a control device for a boiled water machine, such as... Figure 4 As shown, it includes:

[0090] Extended heating control module 404 is used to control the water purifier to perform extended heating according to the determined extended heating mode.

[0091] In some optional implementations, the extended heating mode determination module 403 is specifically used to: determine whether the first temperature is less than a preset first threshold; when the first temperature is less than the first threshold, use the full dry-burning mode as the extended heating mode of the hot water machine; when the first temperature is greater than or equal to the first threshold, use the semi-dry-burning mode as the extended heating mode of the hot water machine.

[0094] In some optional embodiments, the control device for the boiled water dispenser further includes a water dispensing time processing module. Before acquiring the first temperature of the heating element at the current moment, the water dispensing time processing module is used to acquire the actual water dispensing time of the boiled water dispensing operation; determine whether the actual water dispensing time is greater than a preset third threshold; when the actual water dispensing time is greater than the third threshold, the step of acquiring the first temperature of the heating element at the current moment is executed.

[0095] In some optional embodiments, the control device for the boiled water dispenser further includes a water dispensing mode processing module. Before obtaining the actual water dispensing time of the boiled water dispensing operation, the water dispensing mode processing module is used to: obtain the water dispensing mode of the boiled water dispensing operation; when the water dispensing mode is variable water dispensing, perform the step of obtaining the actual water dispensing time of the boiled water dispensing operation.

Figure 5 As shown, the computer device includes one or more processors 10, memory 20, and interfaces for connecting the components, including high-speed interfaces and low-speed interfaces. The components communicate with each other via different buses and can be mounted on a common motherboard or otherwise installed as needed. The processors can process instructions executed within the computer device, including instructions stored in or on memory to display graphical information of a GUI on external input / output devices (such as display devices coupled to the interfaces).
