Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and in particular to a water cooking machine, a control method and device for the water cooking machine, and computer equipment. Background Art

[0002] With the improvement of living standards, the performance of water purifiers has been continuously improved. As the new favorite of the industry, the boiled water machine is mainly able to quickly provide boiled water at different temperatures, and is deeply favored by consumers. The reason why the boiled water machine can provide boiled water at different temperatures is essentially to boil the raw water first, and then cool it to the set temperature, where the cooling is achieved by the heat exchanger. In order to achieve the effect of rapid cooling while taking into account the appearance requirements of the small size of the whole machine, the heat exchange flow channel is usually designed to be W-shaped. If the water pump stops pumping water in this pipeline design, the water in the heating body will gather at the bottom of the heat exchanger under the action of gravity and cannot be discharged from the water outlet in time. It is easy to produce dead water when not used for a long time. Moreover, when the boiled water mode is started next time, this part of cold water will cause the initial water outlet temperature of the boiled water machine to be lower than the set water outlet temperature, resulting in a poor user experience. Summary of the invention

[0003] In view of this, the present invention provides a water cooker, a control method, a device and a computer equipment for the water cooker to solve the problem of low initial water outlet temperature of the water cooker due to cold water in the heat exchanger of the water cooker.

[0004] In a first aspect, the present invention provides a control method for a water cooking machine, comprising the following steps: when the operation of taking cooked water stops, obtaining a first temperature of the heating element at the current moment; obtaining a preset first threshold value, wherein the first threshold value is determined according to the action temperature of a temperature limiter; determining an extended heating mode of the water cooking machine according to a relationship between the first temperature and the first threshold value; and controlling the water cooking machine to perform extended heating according to the determined extended heating mode.

[0005] The control method of the water cooking machine provided by the present invention can determine the extended heating mode of the water cooking machine according to the size relationship between the first temperature and the first threshold value by obtaining the first temperature of the heating element at the current moment and the preset first threshold value when the operation of taking cooked water is stopped, and further control the water cooking machine to perform extended heating according to the determined extended heating mode. The extended heating after the operation of taking cooked water is stopped makes it impossible for the energy generated by the heating element to be carried away by the water flow, resulting in the vaporization of water inside the heating element to generate water vapor, which is discharged through the heat exchange flow channel, thereby pushing the residual water inside the heat exchange flow channel to flow out to the water outlet, so that the heat exchange flow channel is emptied, thereby solving the problem that the initial water outlet temperature of the water cooking machine is lower than the set water outlet temperature due to the presence of cold water in the heat exchanger of the water cooking machine, and the extended heating will not cause the temperature limiter to operate.

[0006] In an optional embodiment, based on the relationship between the first temperature and the first threshold, determining the extended heating mode of the water delivery machine includes: judging whether the first temperature is less than a preset first threshold; when the first temperature is less than the first threshold, using the full dry-burning mode as the extended heating mode of the water cooking machine; when the first temperature is greater than or equal to the first threshold, using the semi-dry-burning mode as the extended heating mode of the water cooking machine.

[0007] That is to say, when the first temperature is relatively low (the first temperature is less than the first threshold), the extended heating adopts the full dry burning method. Since the actual temperature of the heater is relatively low at this time, the extended heating will not cause the action of the temperature limiter even if the full dry burning method is adopted. When the first temperature is relatively high (the first temperature is greater than or equal to the first threshold), the extended heating adopts the semi-dry burning method. Since the actual temperature of the heater is relatively high at this time, in order not to cause the action of the temperature limiter, the extended heating needs to adopt the semi-dry burning method.

[0008] In an optional embodiment, controlling the water boiled water machine for extended heating according to the determined extended heating mode includes: when the extended heating mode is the full dry burning mode, controlling the water pump to stop pumping water but the heating element to continue heating; obtaining the second temperature of the heating element at the current moment; determining whether the second temperature is less than a 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 element to continue heating; when the second temperature is greater than or equal to the first threshold value, controlling the heating element to stop heating.

[0009] That is to say, when the first temperature is relatively low (the first temperature is less than the first threshold value) and the extended heating is performed in a full dry-burning manner, whether to exit the extended heating is determined by judging whether the actual temperature of the heater is greater than or equal to the first threshold value.

[0010] In an optional embodiment, controlling the water boiled water machine to perform extended heating according to the determined extended heating mode includes: when the extended heating mode is the semi-dry burning mode, controlling the water pump to pump water at a preset flow rate and the heating element continues to heat; obtaining the actual duration of the semi-dry burning mode; judging whether the actual duration reaches a preset second threshold; when the actual duration reaches the second threshold, controlling the water pump to stop pumping water and the heating element stops heating.

[0011] That is to say, when the first temperature is relatively high (the first temperature is greater than or equal to the first threshold) and the extended heating is performed in a semi-dry heating manner, whether to exit the extended heating is determined by judging whether the actual duration of the heating by the heater reaches the second threshold.

[0012] In an optional embodiment, before obtaining the first temperature of the heating element at the current moment, the following steps are also included: obtaining the actual water extraction time of the boiled water extraction operation; determining whether the actual water extraction time is greater than a preset third threshold; when the actual water extraction time is greater than the third threshold, executing the step of obtaining the first temperature of the heating element at the current moment.

[0013] That is to say, only when the water volume exceeds the fourth threshold (equivalent to the actual water extraction time being greater than the third threshold), the heating is extended after the water extraction is completed. This is because if the user continuously operates water extraction, water stop, water extraction..., and performs extended heating after each water extraction, the heat will continue to accumulate, causing the heating element to dry burn, affecting the life of the entire machine or abnormal tripping of the temperature limiter. The present invention only performs extended heating after the water extraction is completed when the actual water extraction time exceeds the third threshold, thereby preventing dry burning abnormalities from occurring inside the heating element even if water is frequently extracted.

[0014] In an optional embodiment, before obtaining the actual water extraction time of the cooked water extraction operation, the following steps are also included: obtaining the water extraction mode of the cooked water extraction operation; when the water extraction mode is indefinite water extraction, executing the step of obtaining the actual water extraction time of the cooked water extraction operation.

[0015] That is to say, when the water collection mode is unquantified water collection, it is necessary to determine whether the actual water collection volume exceeds the preset fourth threshold value according to the actual water collection time. When the water collection mode is quantitative water collection, because the actual water collection volume of quantitative water collection is large, it generally exceeds the preset fourth threshold value, so there is no need to determine whether the actual water collection volume during quantitative water collection exceeds the preset fourth threshold value.

[0016] In the second aspect, the present invention also provides a control device for a water cooker, comprising a first acquisition module, a second acquisition module, an extended heating mode determination module and an extended heating control module; the first acquisition module is used to acquire the first temperature of the heating element at the current moment when the cooked water extraction operation stops; the second acquisition module is used to acquire a preset first threshold value, wherein the first threshold value is determined according to the action temperature of the temperature limiter; the extended heating mode determination module is used to determine the extended heating mode of the water cooker according to the relationship between the first temperature and the first threshold value; the extended heating control module is used to control the water cooker to perform extended heating according to the determined extended heating mode.

[0017] In a third aspect, the present invention further provides a computer device, comprising a memory and a processor, the memory and the processor being communicatively connected to each other, the memory storing computer instructions, and the processor executing the control device of the water cooking machine of the first aspect or any corresponding embodiment thereof by executing the computer instructions.

[0018] In a fourth aspect, the present invention further provides a water cooking machine, comprising the computer device of the third aspect.

[0019] In a fifth aspect, the present invention further provides a computer-readable storage medium having computer instructions stored thereon, the computer instructions being used to enable a computer to execute the control device for the water cooking machine of the first aspect or any corresponding embodiment thereof.

[0020] In a sixth aspect, the present invention further provides a computer program product, comprising computer instructions for causing a computer to execute the control device of the water cooking machine of the first aspect or any corresponding embodiment thereof.

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

[0022] (1) When the operation of taking cooked water is stopped, by obtaining the first temperature of the heating element at the current moment and the preset first threshold value, the extended heating mode of the water cooking machine can be determined according to the size relationship between the first temperature and the first threshold value, and the water cooking machine is further controlled to perform extended heating according to the determined extended heating mode. The extended heating after the operation of taking cooked water is stopped makes it impossible for the energy generated by the heating element to be carried away by the water flow, resulting in the evaporation of water inside the heating element to generate water vapor, which is discharged through the heat exchange flow channel, thereby pushing the residual water inside the heat exchange flow channel to flow out to the water outlet, so that the heat exchange flow channel is emptied, thereby solving the problem that the initial water outlet temperature of the water cooking machine is lower than the set water outlet temperature due to the presence of cold water in the heat exchanger of the water cooking machine, and the extended heating will not cause the temperature limiter to operate.

[0023] (2) Extended heating is performed after the water extraction is completed only when the water extraction volume exceeds the fourth threshold value (equivalent to the actual water extraction time being greater than the third threshold value). This is because if the user continuously operates water extraction, water stop, water extraction..., and performs extended heating after each water extraction, the heat will continue to accumulate, causing the heating element to dry out, affecting the life of the entire machine or abnormal tripping of the temperature limiter. The present invention only performs extended heating after the water extraction is completed when the actual water extraction time exceeds the third threshold value, thereby preventing dry-burning abnormalities from occurring inside the heating element even if water is frequently extracted. Furthermore, when the water extraction mode is unquantified water extraction, it is necessary to determine whether the actual water extraction volume exceeds the preset fourth threshold value based on the actual water extraction time. When the water extraction mode is quantitative water extraction, because the actual water extraction volume of quantitative water extraction is relatively large, it generally exceeds the preset fourth threshold value, so there is no need to determine whether the actual water extraction volume during quantitative water extraction exceeds the preset fourth threshold value.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

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

[0032] In this embodiment, a control method for a water cooker is provided, which can be used in the above-mentioned computer device. In this embodiment, the water cooker is a water cooker using rare earth thick film heating. This is because the power density of conventional heating wires and quartz tubes is 20W / cm 2 The power density of this type of heating element is very high, up to 70W / cm 2 Once dry-burned, the temperature rise rate can reach 80℃ / S, which poses a fire safety hazard. Therefore, dry-burning heating elements of such materials are strictly prohibited.

[0033] Figure 1 : is a flow chart of a method for controlling a water boiled water machine according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0034] Step S101: when the boiled water extraction operation stops, obtaining the first temperature of the heating element at the current moment.

[0035] Specifically, a temperature sensor may be provided in the heating element, and the first temperature of the heating element at the current moment may be acquired through the temperature sensor.

[0036] Step S102: obtaining a preset first threshold value, wherein the first threshold value is determined according to an operating temperature of a 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 runs at 1.15 times the rated power to a steady state, detects the stable temperature T1 at the temperature limiter position on the surface of the heating element, and then tests the temperature T2 at the temperature limiter position under abnormal extreme conditions. The operating temperature TS of the temperature limiter can be selected between T1 and T2.

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

[0039] Step S103: Determine the extended heating mode of the water cooker according to the magnitude relationship between the first temperature and the first threshold.

[0040] Specifically, the extended heating mode includes a full dry burning mode and a semi-dry burning mode. For example, all heating products on the market are used with a temperature limiter to meet safety standards. When the heating is extended, it is also necessary not to cause the temperature limiter to operate. Therefore, it is necessary to determine whether the extended heating adopts a full dry burning mode or a semi-dry burning mode according to the first temperature and the first threshold of the heating element at the current moment.

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

[0042] The control method of the water cooker provided in the present embodiment can determine the extended heating mode of the water cooker according to the size relationship between the first temperature and the first threshold value by obtaining the first temperature of the heating element at the current moment and the preset first threshold value when the operation of taking cooked water is stopped, and further control the water cooker to perform extended heating according to the determined extended heating mode. The extended heating after the operation of taking cooked water is stopped makes it impossible for the energy generated by the heating element to be carried away by the water flow, resulting in the vaporization of water inside the heating element to generate water vapor, which is discharged through the heat exchange flow channel, thereby pushing the residual water inside the heat exchange flow channel to flow out to the water outlet, so that the heat exchange flow channel is emptied, thereby solving the problem that the initial water outlet temperature of the water cooker is lower than the set water outlet temperature due to the presence of cold water in the heat exchanger of the water cooker, and the extended heating will not cause the temperature limiter to operate.

[0043] In this embodiment, a control method for a water cooking machine is provided, which can be used for the above-mentioned computer device. Figure 2 FIG. 4 is a flow chart of another water boiling machine control method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0044] Step S201: when the boiled water extraction operation stops, obtaining 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 according to an operating temperature of a temperature limiter.

[0046] In an optional implementation, the first threshold may be the operating temperature TS of the temperature limiter minus a temperature value, for example, the first threshold is equal to the operating temperature TS of the temperature limiter minus 10° C. Step S203: Determine the extended heating mode of the water cooker according to the magnitude relationship between the first temperature and the first threshold.

[0047] In an optional implementation, determining the extended heating mode of the water delivery machine according to the magnitude relationship between the first temperature and the first threshold value includes the following steps S2031 to S2033.

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

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

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

[0051] That is to say, when the first temperature is relatively low (the first temperature is less than the first threshold), the extended heating adopts the full dry burning method. Since the actual temperature of the heater is relatively low at this time, the extended heating will not cause the action of the temperature limiter even if the full dry burning method is adopted. When the first temperature is relatively high (the first temperature is greater than or equal to the first threshold), the extended heating adopts the semi-dry burning method. Since the actual temperature of the heater is relatively high at this time, in order not to cause the action of the temperature limiter, the extended heating needs to adopt the semi-dry burning method.

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

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

[0054] In an optional embodiment, controlling the water cooker 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 the full dry-burning mode, the water pump is controlled to stop pumping water but the heating element continues to heat.

[0056] In an optional embodiment, 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 value. When the second temperature is less than the first threshold value, return to step Sa2; otherwise, enter step Sa4.

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

[0060] That is to say, when the first temperature is relatively low (the first temperature is less than the first threshold value) and the extended heating is performed in a full dry-burning manner, whether to exit the extended heating is determined by judging whether the actual temperature of the heater is greater than or equal to the first threshold value.

[0061] In another optional embodiment, controlling the water cooker 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 the semi-dry heating mode, the water pump is controlled to pump water according to a preset flow rate and the heating element continues to heat.

[0063] In an optional embodiment, the heater is controlled to heat at full power, and the water pump pumps 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 reaches a preset second threshold; when the actual duration reaches the second threshold, proceed to step Sb4; otherwise, return to step Sb2.

[0066] The second threshold value can be predetermined and set in a computer device. The method for determining the second threshold value includes: testing the time for draining the residual water inside the heat exchanger when the whole heating element is at full power and the water pump is pumping water at the minimum flow rate, and determining the second threshold value according to the time obtained by the test.

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

[0068] That is to say, when the first temperature is relatively high (the first temperature is greater than or equal to the first threshold) and the extended heating is performed in a semi-dry heating manner, whether to exit the extended heating is determined by judging whether the actual duration of the heating by the heater reaches the second threshold.

[0069] This embodiment provides an extended heating control logic applied to the boiled water machine, that is, after the customer stops the boiled water function, the internal program defaults to fully open the heating element for a certain period of time, the self-priming water pump does not work or runs at a specific flow rate, and the heating element is used to quickly heat up to generate superheated steam to push the residual water in the heat exchange flow channel out to the water outlet. After a reasonable extended heating operation, the entire heat exchange flow channel has been basically emptied, thereby effectively solving the problem of storing dead water and the low temperature of the first cup of water in the industry.

[0070] In this embodiment, a control method for a water cooking machine is provided, which can be used for the above-mentioned computer device. Figure 3 FIG. 1 is a flow chart of another method for controlling a water boiling machine according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0071] Step S301: obtaining a water fetching mode for a boiled water fetching operation.

[0072] Specifically, the water dispensing mode includes quantitative water dispensing and unquantified water dispensing. Quantified water dispensing is usually divided into 180ml, 300ml, 400ml or other larger water dispensing modes; unquantified water dispensing is when the user starts the water dispensing function by operating the water dispensing button, and presses the water dispensing button again, the water outlet stops dispensing water, and the total water dispensing volume is uncertain.

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

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

[0075] Step S304: Determine whether the actual water extraction time is greater than a preset third threshold; when the actual water extraction 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 fetching time does not increase any more and the longest actual water fetching time is still less than the third threshold, no processing will be performed.

[0077] Among them, the third threshold value can be predetermined and set in a computer device. Specifically, the method for determining the third threshold value includes: calculating the water storage volume inside the heating element according to the structural parameters of the heating element, and calculating the shortest water adding time, that is, the third threshold value, according to the water storage volume inside the heating element and the minimum flow rate of the water discharged by the water boiler. For example, 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 storage volume inside the heating element = 9.5×3.14(2-1) = 29.83ml. Further, assuming that the minimum flow rate of the water pump is 300ml / min, considering that repeated dry burning will occur when water is frequently taken, it is necessary to ensure that the inside of the heating element is full of water each time the heating is extended, so the third threshold value is required to be equal to 29.83×60÷300, that is, 6S.

[0078] That is to say, when the water collection mode is unquantified water collection, it is necessary to determine whether the actual water collection volume exceeds the preset fourth threshold value (e.g., the above-mentioned 29.83 ml) through the actual water collection time. When the water collection mode is quantitative water collection, because the actual water collection volume of quantitative water collection is relatively large, it generally exceeds the preset fourth threshold value, so there is no need to determine whether the actual water collection volume during quantitative water collection exceeds the preset fourth threshold value.

[0079] In this embodiment, the heating is extended after the water extraction is completed only when the water extraction volume exceeds the fourth threshold value (equivalent to the actual water extraction time being greater than the third threshold value). This is because if the user continuously operates water extraction, water stop, water extraction, etc., and performs extended heating after each water extraction, the heat will continue to accumulate, causing the heating element to dry out and affect the life of the entire machine or the temperature limiter to trip abnormally. The heating is extended after the water extraction is completed only when the actual water extraction time exceeds the third threshold value, so that even if water is frequently extracted, dry burning abnormalities will not occur inside the heating element.

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

[0081] Step S306: obtaining a preset first threshold, wherein the first threshold is determined according to the action temperature of the temperature limiter.

[0082] Step S307: Determine the extended heating mode of the water cooker according to the magnitude relationship between the first temperature and the first threshold.

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

[0084] The control method of the water cooker provided in the present embodiment prevents the energy generated by the heating element from being carried away by the water flow by extending the heating after the operation of taking the cooked water is stopped, thereby causing the water inside the heating element to vaporize and generate water vapor, which is discharged through the heat exchange flow channel, thereby pushing the residual water inside the heat exchange flow channel to flow out to the water outlet, so that the heat exchange flow channel is emptied, thereby solving the problem that the initial water outlet temperature of the water cooker is lower than the set water outlet temperature due to the presence of cold water in the heat exchanger of the water cooker, and the extended heating will not cause the temperature limiter to operate; and only when the actual water taking time exceeds the third threshold, the extended heating will be performed after the water taking is completed, thereby even if water is taken frequently, the dry burning abnormality will not occur inside the heating element.
