Description

Liquid heating container and control method and control device thereof

Technical Field

The invention relates to the field of household appliances, in particular to a control method of a liquid heating container, a control device of the liquid heating container and the liquid heating container comprising the control device.

Background

At present, some existing liquid heating containers mainly preserve heat, such as electric hot water bottles, and automatically turn to a certain heat preservation temperature for heat preservation after water boils. However, if the heat preservation is not needed, the user must unplug the power cord or manually shut down the device or perform other related operations to cancel the heat preservation function, which is very inconvenient and affects the application range of the products. For example, in hot regions or high temperature environments such as summer, since users rarely use the heat insulating function, the liquid heating containers such as electric hot water bottles are used less frequently in these regions or in these seasons.

Disclosure of Invention

In order to solve at least one of the above technical problems, an object of the present invention is to provide a control method of a liquid heating vessel.

It is a further object of the present invention to provide a control for a liquid heating vessel.

It is a further object of the present invention to provide a liquid heating vessel incorporating the above control means.

In order to achieve the above object, an embodiment of a first aspect of the present invention provides a control method for a liquid heating container, the liquid heating container including a liner for containing liquid, a heating assembly for heating the liquid in the liner, and an insulating assembly for insulating and heating the liquid in the liner, the control method including: receiving a function instruction, and selecting a function mode corresponding to the function instruction according to the received function instruction; when the functional instruction is a first functional instruction, starting the heating assembly to heat the liquid to boiling, and then stopping all heating functions to naturally cool the liquid to a temperature balance point; when the functional instruction is a second functional instruction, the heating assembly is started to heat the liquid to boiling, and then the heat preservation assembly is started to heat and heat the liquid.

In the method for controlling a liquid heating container according to an embodiment of the first aspect of the present invention, the functional instructions may correspond to a plurality of different functional modes, so that after the liquid heating container completes a heating process, the liquid heating container can be selected to enter a heat preservation state and a natural cooling state, so that a user can obtain drinkable cool boiled liquid, instead of entering the heat preservation state only in the prior art, that is: the liquid heating container is added with a 'cool and white boiling' function mode or a 'self-cooling' mode, in other words, the 'cool and white boiling' or 'self-cooling' mode is added on the basis of the existing 'heating', 'heat preservation setting', 'electric water outlet' function modes and the like, so that different requirements of users are met, the use range of the liquid heating container is expanded (including the use range in regions and the use range in time, the liquid heating container can be used in regions such as hot regions and cold regions, and can be used in seasons such as summer and winter), and the market popularization of products is facilitated.

In other words, the first functional instruction may be a cool-to-white command or a self-cool command or a natural-to-cool command, and if the user issues the first functional instruction at the beginning, the machine will run the first functional mode, namely: heating the liquid to boiling, and then automatically stopping all heating functions to naturally cool the liquid to a temperature balance point which is balanced with the ambient temperature so as to obtain drinkable cool boiled liquid for a user; and the second functional instruction then can be heat preservation heating instruction or heating heat preservation instruction, indicates to accomplish and enters the heat preservation state automatically after the heating process, if the user when beginning, has sent the second functional instruction, then the machine will operate the second functional mode, promptly: the liquid is heated to boiling and then automatically enters a heat preservation state.

It is worth to be noted that, in the processes of heating operation and heat preservation operation, the product needs to heat the liquid, only the heating power is different, so that the heating operation process and the heat preservation operation process can be completed by the same heating device, the heating device has different heating powers, the heating operation adopts high power, and the heat preservation operation adopts low power; of course, the heating operation and the holding operation can also be performed by two separate heating devices, namely: one is used as a heating component for heating operation, and the other is used as a heat preservation component for heat preservation operation. Therefore, in the present application, the heating assembly and the thermal insulation assembly only represent a heating device generating heat during heating operation and a heating device generating heat during thermal insulation operation, respectively, and the two assemblies may be the same heating device or two separate heating devices, which are within the protection scope of the present invention.

In addition, the control method of the liquid heating container in the above embodiment provided by the present invention may further have the following additional technical features:

in the above technical solution, the liquid heating container further comprises a cooling device for cooling the liquid in the inner container; when the function instruction is a second function instruction, before the step of activating the heating component to heat the liquid to boiling, the method further comprises the following steps: receiving a temperature setting instruction; between "start heating element with liquid heating to boiling" step and "start heat preservation subassembly and carry out heat preservation heating to liquid" step, still include: stopping heating of the heating assembly on the liquid so as to naturally cool the liquid to the temperature set by the temperature setting instruction; or stopping heating the liquid by the heating assembly, and simultaneously starting the cooling device to cool the liquid to the temperature set by the temperature setting instruction.

When the received functional instruction is a second functional instruction (namely the received functional instruction corresponds to a second functional mode), if a temperature setting instruction is received before heating is started, after the heating process is completed, and when the liquid is cooled to the temperature set by the temperature setting instruction, the heat preservation assembly is started to heat and preserve heat for the liquid, namely the second functional instruction can be matched with the temperature setting instruction for use, so that the liquid heating container has a heating and heat preservation setting mode, and thus, a user can select the heat preservation temperature of the liquid according to the personal taste or other requirements of the user, thereby further meeting different requirements of the user and improving the use comfort level of the user; as for the cooling process before the heat preservation is started after the boiling, the cooling can be natural cooling (namely, all heating functions are stopped), or active cooling (namely, all heating functions are stopped, and the cooling device is also started), and the cooling device can obviously improve the cooling speed of the liquid, so that the waiting time of a user can be reduced, and the use comfort of the user can be improved.

As to the sequence of receiving the second function instruction and the temperature setting instruction, there is no specific limitation, and the second function instruction may be before the temperature setting instruction, or the temperature setting instruction may be before the temperature setting instruction and the second function instruction may be after the temperature setting instruction.

It should be noted that, for a liquid heating container such as an electric hot water bottle mainly used for heat preservation, the heat preservation temperature may be manually selected or input by a user or may be a default of the product (i.e., the user does not manually select the heat preservation temperature). Such as: the function center is provided with a heat preservation setting module, the heat preservation setting module comprises functions of 'milk making', 'coffee', 'honey', 'scented tea' and the like, different functions correspond to different heat preservation temperatures, for example, 'milk making' corresponds to 45℃, 'coffee' corresponds to 85℃ and the like, a user can set the heat preservation temperature by selecting the functions of 'milk making', 'coffee making' and the like, and can also switch among the functions, of course, for a product with the heat preservation temperature capable of being manually input, the heat preservation can also be manually input by the user; meanwhile, the product is also provided with a default heat preservation temperature (such as 80 ℃), and if the temperature is not set at the beginning of the user, the liquid is heated and boiled and then is preserved at the default heat preservation temperature of the product. Therefore, in the present application, the second function command does not include a separate temperature setting command, but includes information of the heat preservation temperature, and the temperature setting command refers to the heat preservation temperature manually selected or input by the user.

In any one of the above technical solutions, when the function instruction is a second function instruction, before the step of starting the heat-insulating component to heat-insulating and heating the liquid, the method further includes: judging whether a first function instruction is received or not; if a first function instruction is received, stopping all heating functions after the liquid is heated to be boiled so as to naturally cool the liquid to a temperature balance point; and if the first functional instruction is not received, continuing to execute the functional mode corresponding to the second functional instruction.

The method comprises the steps of firstly receiving a second functional instruction, namely the received functional instruction corresponds to a second functional mode, namely the liquid automatically enters a heat preservation state after the heating process is finished, and for the functional mode, before entering the heat preservation state (namely before starting a heat preservation component to preserve heat and heat the liquid), if the first functional instruction is received, the liquid is heated to boiling and then directly enters a natural cooling state, so that the liquid is naturally cooled to a temperature balance point without starting the heat preservation component, and finally the drinkable cool boiled liquid is obtained.

In other words, the first functional instruction can be sent before heating begins, namely, when a user uses the liquid, the liquid can be automatically heated to a boiling state and then automatically cooled naturally, so that the drinkable cold boiled liquid can be obtained by one-time operation of the user, namely, one-key operation is realized, and the operation is very convenient; in the scheme, the first function instruction is received before the heat preservation starts after the heating starts, so that the first function instruction can be sent out before the heat preservation starts after the heating starts, and therefore when the water heater is used by a user, if the second function mode is selected just before the heating starts, and the cool boiled liquid is wanted to be obtained after the heating starts (in the heating process before boiling, or in the cooling process of cooling to the heat preservation temperature after boiling), the second function mode can be switched to the first function mode to continue to operate only by selecting the cool boiled mode or the self-cooling mode, and the cool boiled liquid which can be drunk is finally obtained by the user. Of course, if the first functional instruction is not received, the machine continues to operate the second functional mode.

In any one of the above technical solutions, when the function instruction is a second function instruction, after the step of "starting the heat-insulating component to heat-insulating and heating the liquid", the method further includes: judging whether a first function instruction is received or not; if the first function instruction is received, all heating functions are stopped so that the liquid is naturally cooled to the temperature equilibrium point.

And (2) receiving a second functional instruction, namely the received functional instruction corresponds to a second functional mode, namely the liquid automatically enters a heat preservation state after the heating process is finished, stopping all heating functions after the liquid enters the heat preservation state (namely after the heat preservation component is started to preserve heat and heat the liquid) for the functional mode, naturally cooling the liquid to a temperature balance point, and finally obtaining drinkable cool boiled liquid. In the scheme, the first functional instruction is received in the heat preservation process, so that the first functional instruction can be sent out in the heat preservation process, and therefore when the liquid cooling device is used by a user, if the second functional mode is selected at the beginning and the cool and white boiled liquid is needed to be obtained in the heat preservation process, the cool and white boiled mode or the self-cooling mode is selected.

In any of the above technical solutions, the liquid heating container includes a temperature controller; in the process of starting the heating component to heat the liquid to boiling, judging whether the liquid is boiled or not, and if so, stopping heating the liquid by the heating component; wherein, the temperature controller is an electronic temperature controller, and the step of judging whether the liquid is boiled comprises the following steps: acquiring the liquid temperature detected by the electronic temperature controller in real time; judging whether the temperature of the liquid is gradually increased within an initial preset time period or not; if the temperature of the liquid is gradually increased within the initial preset time period, determining that the liquid is not boiled; if the temperature of the liquid is not gradually increased within the initial preset time period, determining that the liquid is boiled; or, the temperature controller is a mechanical temperature controller, and the step of judging whether the liquid is boiled specifically comprises the following steps: detecting the state of the mechanical temperature controller in real time; judging whether the mechanical temperature controller is tripped off or not; if the mechanical temperature controller is not tripped off, the liquid is judged not to be boiled; if the mechanical thermostat trips, it is determined that the liquid has boiled.

For the technical scheme that the temperature controller of the liquid heating container is the electronic temperature controller, the electronic temperature controller can detect the temperature of liquid in real time, and then can judge whether the temperature of the liquid rises within the initial preset time (namely a period of time from receiving the functional instruction) according to the detection result, so that whether the liquid is boiled can be judged.

Specifically, if the temperature of the liquid gradually rises within the initial preset time period, which indicates that the liquid is still in a temperature-rising state after receiving the functional instruction, the heating process is not completed, and it is determined that the liquid is not boiling; if the temperature of the liquid is not gradually increased within the initial preset time period, namely: if the temperature of the liquid is kept unchanged, then the temperature of the liquid is gradually reduced or gradually reduced, the liquid is in a temperature reduction process after being boiled and before being reduced to the temperature of the heat preservation temperature, so that the heating process is finished, and the liquid is judged to be boiled.

Of course, the liquid temperature may not be obtained from the detection result of the electronic thermostat, for example, a separately provided detection device, such as a temperature sensor, and thus, the present invention is not limited by the spirit and scope of the present invention.

For the technical scheme that the temperature controller of the liquid heating container is a mechanical temperature controller, the temperature change of the liquid in the inner container can be indirectly converted into a mechanical acting force (such as steam pressure) to act on the mechanical temperature controller, so that the mechanical temperature controller is deformed, and when the deformation amount generated by the mechanical temperature controller reaches the corresponding deformation amount when the boiling point of the liquid, the mechanical temperature controller is mechanically tripped; therefore, whether the liquid is boiled or not can be judged according to the state (whether the mechanical temperature controller is tripped or not), so that the scheme indirectly judges whether the liquid is boiled or not according to the state of the mechanical temperature controller and has higher accuracy and reliability.

Specifically, if the mechanical temperature controller is not tripped off, the liquid is still in a temperature rising state after receiving the function instruction, so that the heating process is not finished, and the liquid is judged not to be boiled; if the mechanical thermostat has tripped, indicating that the liquid has boiled, and thus the heating process has been completed, it is determined that the liquid has boiled.

In other words, after mechanical temperature controller detected the water boiling in the inner bag, machinery was jumped absolutely promptly, cut off heating element's power supply, guaranteed simultaneously that the thermal insulation component can not open, and the water in the inner bag is cooled down naturally to last temperature balance point, nevertheless in-process at liquid natural cooling or after the cooling is accomplished, electronic play water function still can use, and the user of being convenient for takes at any time.

Of course, the method for determining whether the liquid is boiled is not limited to the above two methods of analyzing the detection result of the electronic thermostat or the mechanical thermostat, and other methods, such as providing a special detection component for detecting vapor pressure to determine whether the liquid is boiled, etc., may be used as long as the state of the liquid can be reflected and further whether the liquid is boiled, and the technical solutions should be understood by those skilled in the art without departing from the design concept and spirit of the present invention.

In any of the above technical solutions, the liquid heating container includes a reminder; in the process of stopping all heating functions to enable the liquid to be naturally cooled to the temperature balance point, judging whether the liquid is cooled to the temperature balance point or not, and if the liquid is judged to be cooled to the temperature balance point, starting a reminding device to send out a reminding signal; wherein, the step of judging whether the liquid is cooled to the temperature balance point comprises the following steps: detecting the ambient temperature of the liquid heating container and the temperature of the liquid in real time; judging whether the temperature of the liquid is kept within a preset balance temperature range within a preset time; if the temperature of the liquid is kept within the preset equilibrium temperature range within the preset time length, the liquid is judged to be cooled to the temperature equilibrium point; the maximum value of the preset balance temperature range is the sum of the current environment temperature and a preset temperature floating value, and the minimum value of the preset balance temperature range is the sum of the current environment temperature and the preset temperature floating value.

In the above technical solution, preferably, the reminding signal includes an acoustic signal and/or an optical signal; and/or the value range of the preset temperature floating value is 3-7 ℃; and/or the preset duration ranges from 30s to 60 s.

At the in-process of natural cooling, whether the temperature through judging liquid keeps in predetermineeing balanced temperature range in certain time, can accurately learn whether the natural cooling process of liquid has accomplished, promptly: whether the temperature is cooled to a temperature balance point which is balanced with the ambient temperature, wherein the preset balance temperature range is a certain value of the current ambient temperature which can be the same or different. Specifically, if the temperature of the liquid is kept within the preset equilibrium temperature range within the preset duration, it is indicated that the temperature of the liquid has decreased to the equilibrium point and cannot be decreased, and at this time, it can be determined that the natural cooling process of the liquid has been completed, and then the reminding device is started to send a reminding signal.

The reminding device is arranged, so that a user does not need to keep in front of the liquid heating container and repeatedly check before arriving at the machine once, the information can be timely and accurately acquired, and the use comfort of the user is further improved.

Specifically, the reminding signal may be an audio signal, such as "dropping" sound, or playing a piece of music or playing a piece of voice; it can also be a light signal, such as a warning by flashing a signal light; or a combination of both. Of course, the reminding signal is not limited to the sound signal and/or the light signal, and is within the protection scope of the present invention as long as the reminding function is achieved.

The value range of the preset temperature floating value is 3-7 ℃, and 5 ℃ is preferred; the preset time period is in the range of 30s-60s, preferably 45 s. The values of the preset temperature floating value and the preset time are not limited to the above ranges, and can be adjusted correspondingly according to the product structure, the user requirements and the environment of the use area in the actual production process.

An embodiment of the second aspect of the present invention provides a control device for a liquid heating container, the liquid heating container comprising a liner for containing liquid, a heating assembly for heating the liquid in the liner, and an insulating assembly for insulating and heating the liquid in the liner, the control device comprising: the receiving module is used for receiving the functional instruction and selecting the corresponding functional mode according to the received functional instruction; and the control module is used for firstly starting the heating assembly to heat the liquid to boiling when the functional instruction received by the receiving module is a first functional instruction, then stopping all heating functions to naturally cool the liquid to a temperature balance point, and is used for firstly starting the heating assembly to heat the liquid to boiling and then starting the heat-insulating assembly to heat the liquid in a heat-insulating manner when the functional instruction received by the receiving module is a second functional instruction.

In the control device for a liquid heating container according to the embodiment of the second aspect of the present invention, the function instruction received by the receiving module may correspond to a plurality of different function modes, so that after the liquid heating container completes the heating process, the liquid heating container can be selected to enter the heat preservation state and the natural cooling state, so that the user can obtain drinkable cool boiled liquid, instead of entering the heat preservation state only in the prior art, that is: a 'cool and white boiling' function mode or a 'self-cooling' mode is added to the liquid heating container, so that different requirements of users are met, the use range (including the use range in regions and the use range in time) of the liquid heating container is expanded, and the market popularization of products is facilitated.

In other words, the first functional instruction may be a cool and white boiling instruction, a self-cooling instruction or a natural cooling instruction, and if the receiving module receives the first functional instruction at the beginning, the machine will operate the first functional mode, that is, the liquid is heated to boiling first, and then all heating functions are automatically stopped, so that the liquid is naturally cooled to a temperature balance point which is balanced with the ambient temperature, so that the user can obtain drinkable cool and white boiling liquid; and the second functional instruction can be a heat preservation heating instruction or a heating heat preservation instruction, which means that the machine automatically enters a heat preservation state after the heating process is completed, and if the receiving module receives the second functional instruction at the beginning, the machine runs a second functional mode, namely: the liquid is heated to boiling and then automatically enters a heat preservation state.

In addition, the control device in the above embodiment provided by the present invention may further have the following additional technical features:

in the above technical solution, the liquid heating container further comprises a cooling device for cooling the liquid in the inner container; the control module is further used for stopping heating of the liquid by the heating assembly after the heating assembly is started to heat the liquid to boiling and before the heat preservation assembly is started to heat the liquid for heat preservation heating when the function instruction received by the receiving module is a second function instruction and the control module also receives a temperature setting instruction before the heating assembly is started to heat the liquid to boiling, so that the liquid is naturally cooled to the temperature set by the temperature setting instruction; or stopping heating the liquid by the heating assembly, and simultaneously starting the cooling device to cool the liquid to the temperature set by the temperature setting instruction.

When the functional instruction received by the receiving module is a second functional instruction (namely the received functional instruction corresponds to a second functional mode), if the receiving module receives a temperature setting instruction before heating is started, after the heating process is completed, and when the liquid is cooled to the temperature set by the temperature setting instruction, the control module starts the heat preservation assembly to heat and preserve heat for the liquid, namely the second functional instruction can be matched with the temperature setting instruction for use, so that the liquid heating container has a heating and heat preservation setting mode, and thus, a user can select the heat preservation temperature of the liquid according to the personal taste or other requirements of the user, thereby further meeting different requirements of the user and improving the use comfort of the user; as for the cooling process before the heat preservation is started after the boiling, the cooling can be natural cooling (namely, all heating functions are stopped), or active cooling (namely, all heating functions are stopped, and the cooling device is also started), and the cooling device can obviously improve the cooling speed of the liquid, so that the waiting time of a user can be reduced, and the use comfort of the user can be improved.

As for the sequence of the receiving module receiving the second function instruction and the temperature setting instruction, the sequence is not particularly limited, and the second function instruction may be before the temperature setting instruction, or the temperature setting instruction may be before the temperature setting instruction and the second function instruction may be after the temperature setting instruction.

In any one of the above technical solutions, the control device further includes: the initial judgment module is used for judging whether the receiving module receives a first functional instruction before the control module starts the heat preservation assembly to preserve heat and heat the liquid when the functional instruction received by the receiving module is a second functional instruction; the control module is further configured to, when the initial determination module determines that the receiving module receives the first function instruction, stop all heating functions after the liquid is heated to boiling so that the liquid is naturally cooled to a temperature equilibrium point, and continue to execute the function mode corresponding to the second function instruction when the initial determination module determines that the receiving module does not receive the first function instruction.

The receiving module receives a second functional instruction, namely the received functional instruction corresponds to a second functional mode, namely the liquid automatically enters a heat preservation state after the heating process is finished, for the functional mode, before the liquid enters the heat preservation state (namely before the heat preservation component is started to preserve heat and heat the liquid), if the receiving module receives the first functional instruction again, the liquid directly enters a natural cooling state after being heated to boiling, so that the liquid is naturally cooled to a temperature balance point, the heat preservation component is not started any more by the control module, and finally the drinkable cool boiled liquid is obtained.

In other words, the receiving module can receive the first functional instruction before the heating starts, namely, when the user uses the liquid, the machine can automatically enter a heating state by directly selecting a 'cool and white boiling' mode or a 'self-cooling' mode, and automatically enter a natural cooling state after the liquid is heated to be boiled, so that the drinkable cool and white boiling liquid can be obtained by one-time operation of the user, namely, one-key operation is realized, and the operation is very convenient; in the scheme, the first function instruction is received after heating is started and before heat preservation is started, so that the receiving module can also receive the first function instruction after heating is started and before heat preservation is started, and therefore when the multifunctional electric heating kettle is used, if a second function mode is selected just before heating is started and cool boiled liquid is desired to be obtained after heating is started (in the heating process before boiling or in the cooling process of cooling to the heat preservation temperature after boiling), the second function mode can be switched to the first function mode to continue operation only by selecting the cool boiled mode or the self-cooling mode, and the cool boiled liquid which can be drunk is finally obtained by a user. Of course, if the receiving module does not receive the first functional instruction after the heating starts, the machine continues to operate in the second functional mode.

In any one of the above technical solutions, the control device further includes: the judging module is used for judging whether the receiving module receives the first functional instruction or not after the control module starts the heat preservation assembly to preserve heat and heat the liquid when the functional instruction received by the receiving module is the second functional instruction; the control module is further used for stopping all heating functions to naturally cool the liquid to a temperature balance point when the re-judging module judges that the receiving module receives the first function instruction.

The receiving module receives a second functional instruction, namely the received functional instruction corresponds to a second functional mode, namely the liquid automatically enters a heat preservation state after the heating process is finished, and for the functional mode, after the liquid enters the heat preservation state (namely, after the heat preservation assembly is started to preserve heat and heat the liquid), if the receiving module receives the first functional instruction again, the control module stops all heating functions to naturally cool the liquid to a temperature balance point, and finally the drinkable cool boiled liquid is obtained. In the scheme, the first functional instruction is received in the heat preservation process, so that the first functional instruction can be sent out in the heat preservation process, and therefore when the liquid cooling device is used by a user, if the second functional mode is selected at the beginning and the cool and white boiled liquid is needed to be obtained in the heat preservation process, the cool and white boiled mode or the self-cooling mode is selected.

In any of the above technical solutions, the liquid heating container includes a temperature controller; the control device further includes: the first judgment module is used for judging whether the liquid is boiled or not in the process that the control module starts the heating assembly to heat the liquid to be boiled; the control module is further used for stopping heating of the liquid by the heating assembly when the first judging module judges that the liquid is boiled; wherein, the temperature controller is electronic type temperature controller, first judgement module includes: the acquisition unit is used for acquiring the liquid temperature detected by the electronic temperature controller in real time after the receiving module receives the functional instruction; the judging unit is used for judging whether the temperature of the liquid is gradually increased within the initial preset time according to the result obtained by the obtaining unit; and a determination unit for determining that the liquid has not boiled when the determination unit determines that the temperature of the liquid is gradually increased within an initial preset time period, and for determining that the liquid has boiled when the determination unit determines that the temperature of the liquid is not gradually increased within the initial preset time period; or, the temperature controller is a mechanical temperature controller, and the first judgment module includes: the detection unit is used for detecting the state of the mechanical temperature controller in real time after the receiving module receives the functional instruction; the judging unit is used for judging whether the mechanical temperature controller is tripped off or not according to the detection result of the detecting unit; and the determining unit is used for determining that the liquid is not boiled when the judging unit judges that the mechanical temperature controller is not tripped, and is used for determining that the liquid is boiled when the judging unit judges that the mechanical temperature controller is tripped.

Specifically, if the determining unit determines that the temperature of the liquid gradually rises within the initial preset time period, which indicates that the liquid is still in a temperature-rising state after receiving the functional instruction, and thus the heating process is not completed, the determining unit determines that the liquid is not boiled; if the judging unit judges that the temperature of the liquid is not gradually increased within the initial preset time period, namely: the temperature of the liquid is kept unchanged, or is kept unchanged and then gradually reduced, or is gradually reduced, if the temperature is kept unchanged, the liquid is boiling or is in a heat preservation state, and if the temperature is kept unchanged and then gradually reduced or is gradually reduced, the liquid is in a temperature reduction process after boiling and before being reduced to the heat preservation temperature, so that the heating process is finished, and the determining unit determines that the liquid is boiling.

For the technical scheme that the temperature controller of the liquid heating container is a mechanical temperature controller, the temperature change of the liquid in the inner container can be indirectly converted into a mechanical acting force (such as steam pressure) to act on the mechanical temperature controller, so that the mechanical temperature controller is deformed, and when the deformation amount generated by the mechanical temperature controller reaches the corresponding deformation amount when the boiling point of the liquid, the mechanical temperature controller is mechanically tripped; therefore, the judging unit can judge whether the liquid is boiled or not according to the state (whether the mechanical temperature controller is tripped or not) of the mechanical temperature controller, then the judging result is sent to the determining unit, and the determining unit can determine whether the liquid is boiled or not. And after liquid natural cooling or cooling are accomplished, electronic play water function still can use, and the user of being convenient for takes at any time.

Specifically, if the determining unit determines that the mechanical temperature controller is not tripped, indicating that the liquid is still in a temperature-rising state after receiving the functional instruction, and thus the heating process is not completed, the determining unit determines that the liquid is not boiled; if the determination unit determines that the mechanical thermostat has tripped off, indicating that the liquid has boiled, and thus the heating process has been completed, the determination unit determines that the liquid has boiled.

Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

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 specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

A liquid heating container, a control method thereof, and a control apparatus thereof according to some embodiments of the present invention will be described below with reference to fig. 1 to 7.

As shown in fig. 1, an embodiment of the first aspect of the present invention provides a method for controlling a liquid heating container, including the steps of:

s102: receiving a function instruction, and selecting a function mode corresponding to the function instruction according to the received function instruction; when the function instruction is a first function instruction, executing step S106 first, and then executing step S302, and when the function instruction is a second function instruction, executing step S106 first, and then executing step S202;

s106: activating the heating assembly 30 to heat the liquid to boiling;

s202: starting the heat preservation assembly to preserve heat and heat the liquid;

s302: all heating functions are stopped to allow the liquid to cool naturally to the temperature equilibrium point.

It is worth to be noted that, in the processes of heating operation and heat preservation operation, the product needs to heat the liquid, only the heating power is different, so that the heating operation process and the heat preservation operation process can be completed by the same heating device, the heating device has different heating powers, the heating operation adopts high power, and the heat preservation operation adopts low power; of course, the heating operation and the holding operation can also be performed by two separate heating devices, namely: one as a heating assembly 30 for heating operation and the other as a keep warm assembly for keep warm operation. Therefore, in the present application, the heating assembly 30 and the thermal insulation assembly merely represent a heating device generating heat during heating operation and a heating device generating heat during thermal insulation operation, respectively, and the two assemblies may be the same heating device or two separate heating devices, which are within the protection scope of the present invention.

In an embodiment of the present invention, as shown in fig. 2, when the functional instruction is a second functional instruction, the process specifically includes the following steps:

s1022: receiving a second function instruction;

s104: receiving a temperature setting instruction;

s106: activating the heating assembly 30 to heat the liquid to boiling;

s108: stopping heating the liquid by the heating assembly 30 so as to naturally cool the liquid to the temperature set by the temperature setting instruction;

s202: and starting the heat preservation assembly to preserve heat and heat the liquid.

In another embodiment of the present invention, as shown in fig. 3, when the functional instruction is a second functional instruction, the process specifically includes the following steps:

s102: receiving a second function instruction;

s104: receiving a temperature setting instruction;

s106: activating the heating assembly 30 to heat the liquid to boiling;

s110: stopping heating the liquid by the heating assembly 30, and simultaneously starting the cooling device to cool the liquid to the temperature set by the temperature setting instruction;

In the two embodiments, when the received functional instruction is the second functional instruction (that is, the received functional instruction corresponds to the second functional mode), if the temperature setting instruction is received before heating is started, after the heating process is completed, and when the liquid is cooled to the temperature set by the temperature setting instruction, the heat preservation assembly is started to heat and preserve heat for the liquid, that is, the second functional instruction can be used in combination with the temperature setting instruction, so that the liquid heating container has the heating and heat preservation setting mode, and thus, a user can select the heat preservation temperature of the liquid according to the personal taste or other requirements of the user, thereby further meeting different requirements of the user and improving the use comfort of the user; as for the cooling process before the heat preservation is started after the boiling, the cooling can be natural cooling (namely, all heating functions are stopped), or active cooling (namely, all heating functions are stopped, and the cooling device is also started), and the cooling device can obviously improve the cooling speed of the liquid, so that the waiting time of a user can be reduced, and the use comfort of the user can be improved.

In any of the above embodiments, when the functional instruction is a second functional instruction, before step S202, the method further includes the following steps:

s112: and judging whether the first function instruction is received, if so, executing step S302 after the liquid is heated to boiling, and if not, continuing to execute the function mode corresponding to the second function instruction, as shown in fig. 4.

In other words, the first functional instruction can be sent before heating begins, namely, when a user uses the liquid, the liquid can be automatically heated to a boiling state and then automatically cooled naturally, so that the drinkable cold boiled liquid can be obtained by one-time operation of the user, namely, one-key operation is realized, and the operation is very convenient; for this embodiment, the first function instruction is received after the heating is started and before the heat preservation is started, so that the first function instruction may be sent before the heat preservation is started after the heating is started, and thus when the user uses the liquid beverage, if the user just starts to select the second function mode, and wants to obtain cool boiled liquid after the heating is started (either during the heating before boiling or during the cooling after boiling to the heat preservation temperature), the user only needs to select the "cool boiled" mode or the "self-cooling" mode again, and then the second function mode may be switched to the first function mode to continue to operate, and the user finally obtains the drinkable cool boiled liquid. Of course, if the first functional instruction is not received, the machine continues to operate the second functional mode.

In any of the above embodiments, when the functional instruction is a second functional instruction, after step S202, the method further includes:

s204: it is determined whether the first function instruction is received, and if the first function instruction is received, step S302 is executed, as shown in fig. 4.

In any of the above embodiments, the liquid heating vessel comprises a thermostat 50; in the process of starting the heating assembly 30 to heat the liquid to boiling, whether the liquid is boiled or not is judged, and if the liquid is judged to be boiled, the heating assembly 30 stops heating the liquid.

Optionally, the temperature controller 50 is an electronic temperature controller 50, and the step of "determining whether the liquid is boiled" includes:

acquiring the liquid temperature detected by the electronic temperature controller 50 in real time;

and judging whether the temperature of the liquid is gradually increased within an initial preset time period or not, if so, judging that the liquid is not boiled, and if not, judging that the liquid is boiled.

For the technical scheme that the temperature controller 50 of the liquid heating container is the electronic temperature controller 50, the electronic temperature controller 50 can detect the temperature of the liquid in real time, and then can judge whether the temperature of the liquid is increased within the initial preset time (namely, a period of time from receiving the functional instruction) according to the detection result, so that whether the liquid is boiled or not can be judged.

Of course, the liquid temperature may not be obtained from the detection result of the electronic temperature controller 50, for example, a separately provided detection device, such as a temperature sensor, and thus, the present invention is not limited by the spirit and scope of the present invention.

Optionally, the thermostat 50 is a mechanical thermostat 50, and the step of "determining whether the liquid has boiled" includes:

detecting the state of the mechanical temperature controller 50 in real time;

and judging whether the mechanical temperature controller 50 is tripped off, if the mechanical temperature controller 50 is not tripped off, judging that the liquid is not boiled, and if the mechanical temperature controller 50 is tripped off, judging that the liquid is boiled.

For the technical scheme that the temperature controller 50 of the liquid heating container is a mechanical temperature controller 50, the temperature change of the liquid in the inner container 11 can be indirectly converted into a mechanical acting force (such as steam pressure) to act on the mechanical temperature controller 50, so that the mechanical temperature controller 50 deforms, and when the deformation amount of the mechanical temperature controller 50 reaches the corresponding deformation amount when the liquid is boiled, the mechanical temperature controller 50 is mechanically tripped; therefore, it can be determined whether the liquid is boiled or not according to the state (whether the mechanical temperature controller 50 is tripped or not), so that the solution has higher accuracy and reliability although indirectly determining whether the liquid is boiled or not according to the state of the mechanical temperature controller 50.

Specifically, if the mechanical temperature controller 50 is not tripped, it indicates that the liquid is still in a temperature-rising state after receiving the functional instruction, so that the heating process is not completed, and it is determined that the liquid is not boiling; if the thermostat 50 has tripped, indicating that the liquid has boiled, and thus the heating process is complete, it is determined that the liquid has boiled.

In other words, after mechanical temperature controller 50 detects the water boiling in inner bag 11, machinery jump promptly, cuts off heating element 30's power supply, guarantees simultaneously that the thermal insulation component can not open, and the water in the inner bag 11 cools down naturally to final temperature balance point, nevertheless in-process at liquid natural cooling or after the cooling is accomplished, electronic play water function still can use, and the user of being convenient for takes at any time.

Of course, the method for determining whether the liquid is boiled is not limited to the above two methods of analyzing the detection result of the electronic temperature controller 50 or the mechanical temperature controller 50, and other methods, such as providing a special detection component for detecting vapor pressure to determine whether the liquid is boiled, etc., may be used as long as the state of the liquid can be reflected and further the liquid is boiled.

In any of the above embodiments, the liquid heating vessel comprises a reminder device; in the process of stopping all heating functions to naturally cool the liquid to the temperature balance point, judging whether the liquid is cooled to the temperature balance point or not, and if the liquid is cooled to the temperature balance point, starting a reminding device to send a reminding signal.

Wherein, the step of judging whether the liquid is cooled to the temperature balance point comprises the following steps:

detecting the ambient temperature of the liquid heating container and the temperature of the liquid in real time;

judging whether the temperature of the liquid is kept within a preset balance temperature range within a preset time, and if the temperature of the liquid is kept within the preset balance temperature range within the preset time, judging that the liquid is cooled to a temperature balance point;

the maximum value of the preset balance temperature range is the sum of the current environment temperature and a preset temperature floating value, and the minimum value of the preset balance temperature range is the sum of the current environment temperature and the preset temperature floating value.

Preferably, the alert signal comprises an acoustic signal and/or a light signal.

Preferably, the value range of the preset temperature floating value is 3-7 ℃.

Preferably, the preset time period ranges from 30s to 60 s.

As shown in fig. 5, the control device 100 according to the second aspect of the present invention is a liquid heating container, the liquid heating container includes a liner 11 for containing liquid, a heating assembly 30 for heating the liquid in the liner 11, and an insulating assembly for insulating and heating the liquid in the liner 11, the control device 100 includes: a receiving module 200 and a control module 300.

In other words, the first functional instruction may be a cool and white boiling instruction, a self-cooling instruction, or a natural cooling instruction, and if the receiving module 200 receives the first functional instruction at the beginning, the machine will operate the first functional mode, that is, first heat the liquid to boiling, and then automatically stop all heating functions, so that the liquid is naturally cooled to a temperature equilibrium point which is in equilibrium with the ambient temperature, so that the user can obtain drinkable cool and white boiling liquid; and the second functional instruction may be a heat preservation heating instruction or a heating heat preservation instruction, which means that the machine automatically enters a heat preservation state after the heating process is completed, and if the receiving module 200 receives the second functional instruction at the beginning, the machine will operate a second functional mode, that is: the liquid is heated to boiling and then automatically enters a heat preservation state.

In some embodiments of the present invention, the liquid heating container further includes a cooling device for cooling the liquid in the inner container 11; the control module 300 is further configured to, when the function instruction received by the receiving module 200 is a second function instruction and a temperature setting instruction is received before the control module 300 starts the heating assembly 30 to heat the liquid to the boiling state, stop heating the liquid by the heating assembly 30 after the heating assembly 30 is started to heat the liquid to the boiling state and before the heat preservation assembly is started to heat the liquid, so that the liquid is naturally cooled to the temperature set by the temperature setting instruction; alternatively, the heating of the liquid by the heating assembly 30 is stopped, and the cooling device is turned on to cool the liquid to the temperature set by the temperature setting instruction.

When the functional instruction received by the receiving module 200 is a second functional instruction (i.e., the received functional instruction corresponds to a second functional mode), if the receiving module 200 further receives a temperature setting instruction before heating starts, after the heating process is completed, and when the liquid is cooled to the temperature set by the temperature setting instruction, the control module 300 starts the heat-insulating assembly to heat-insulate and heat the liquid, that is, the second functional instruction can be used in combination with the temperature setting instruction, so that the liquid heating container has a heating and heat-insulating setting mode, and thus, a user can select the heat-insulating temperature of the liquid according to the personal taste or other requirements of the user, thereby further meeting different requirements of the user and improving the use comfort of the user; as for the cooling process before the heat preservation is started after the boiling, the cooling can be natural cooling (namely, all heating functions are stopped), or active cooling (namely, all heating functions are stopped, and the cooling device is also started), and the cooling device can obviously improve the cooling speed of the liquid, so that the waiting time of a user can be reduced, and the use comfort of the user can be improved.

The receiving module 200 receives the second function instruction, that is, the received function instruction corresponds to the second function mode, that is, the liquid automatically enters the heat preservation state after the heating process is completed, for the function mode, before entering the heat preservation state (that is, before the heat preservation component is started to preserve heat and heat the liquid), if the receiving module 200 receives the first function instruction, the liquid is heated to boiling and then directly enters the natural cooling state, so that the liquid is naturally cooled to the temperature balance point, the heat preservation component is not started any more by the control module 300, and finally the drinkable cool boiled liquid is obtained.

In other words, the receiving module 200 receives the first function instruction before the heating starts, that is, when the user uses the liquid, the user directly selects the "cool and white boiling" mode or the "self cooling" mode, the machine can automatically enter the heating state, and after the liquid is heated to the boiling state, the machine automatically enters the natural cooling state, so that the drinkable cool and white boiling liquid can be obtained by one-time operation of the user, that is, one-key operation is realized, and the operation is very convenient; in the scheme, the first function instruction is received after heating is started and before heat preservation is started, so that the receiving module 200 can also receive the first function instruction after heating is started and before heat preservation is started, so that when a user uses the liquid cooling device, if the user just starts to select the second function mode, and wants to obtain cool boiled liquid after heating is started (in the heating process before boiling, or in the cooling process of cooling to the heat preservation temperature after boiling), the user only needs to select the cool boiled mode or the self-cooling mode again, and then the second function mode can be switched to the first function mode to continue to operate, and the user finally obtains the drinkable cool boiled liquid.

The receiving module 200 receives the second function instruction, that is, the received function instruction corresponds to the second function mode, that is, the liquid automatically enters the heat preservation state after the heating process is completed, for the function mode, after the liquid enters the heat preservation state (that is, after the heat preservation assembly is started to preserve heat and heat the liquid), if the receiving module 200 receives the first function instruction again, the control module 300 stops all heating functions, so that the liquid is naturally cooled to the temperature balance point, and finally, the drinkable cool boiled liquid is obtained. In the scheme, the first functional instruction is received in the heat preservation process, so that the first functional instruction can be sent out in the heat preservation process, and therefore when the liquid cooling device is used by a user, if the second functional mode is selected at the beginning and the cool and white boiled liquid is needed to be obtained in the heat preservation process, the cool and white boiled mode or the self-cooling mode is selected.
