Description

Technical Field

[0001] This invention relates to the field of water dispensers, and more specifically to a heating control method for a water dispenser and a water dispenser. Background Technology

[0002] Water dispensers provide a convenient supply of hot water to users. Common types include small boiling devices like electric kettles and water boilers, as well as large-capacity electric water dispensers. During the heating process, water often needs to be added midway through the process. Compared to small boiling devices like electric kettles and water boilers, water dispensers can provide a continuous supply of hot water through large-capacity heat preservation. In actual use, users add water to the dispenser while it's in operation using a kettle. There are two scenarios: adding water that can be drunk directly, and adding raw water that needs to be boiled before drinking. Some water dispensers on the market currently boil all the water upon addition, as seen in Chinese patent [CN 108338653 A], where an electric kettle re-boiles the water after adding ingredients or water, preventing liquid overflow during cooking. Alternatively, they can maintain the temperature at a set level. For users adding water that can be drunk directly, they need to wait for the water to cool to the desired temperature before drinking. However, when the water is kept at the target temperature, there is a risk that users might add tap water before it has been boiled, resulting in them drinking unboiled water. To prevent this, related technologies incorporate water quality detection devices. However, these devices not only increase the cost of the water dispenser but also complicate its structure and circuitry, potentially affecting its reliability.

[0003] To address the aforementioned issues, existing water dispensers without water quality testing devices may result in users drinking unboiled water after adding tap water, or the added drinking water may require boiling and then cooling to the desired temperature. Therefore, effectively detecting water addition and preventing users from drinking unboiled water or requiring boiling and then cooling drinking water to the desired temperature are urgent problems to be solved. Summary of the Invention

[0004] In order to solve the technical problems described in the background art, the first objective of the present invention is to provide a heating control method for a water dispenser. This method detects whether a water adding action has occurred by detecting the water temperature inside the water dispenser components and determining whether the water temperature has changed abruptly. When the user performs the water adding action, the heating operation is performed according to the user's preferred heating mode, thereby avoiding the problem of drinking raw water after the user adds unboiled water or the problem of needing to boil and then lower the temperature to the desired temperature after the user adds drinking water.

[0005] The second objective of this invention is to provide a water dispenser.

[0006] To achieve the aforementioned primary objective, this application adopts the following technical solution:

[0007] A heating control method for a water dispenser, the water dispenser comprising: a pot body assembly for storing water; a heating module for heating the water in the pot body assembly; and a temperature measuring module for detecting the water temperature in the pot body assembly. The heating control method includes: acquiring the water temperature in the pot body assembly; determining whether the water temperature has a sudden change; and when the water temperature has a sudden change, controlling the heating module to heat the water in the pot body assembly according to the user's preferred heating mode.

[0008] Furthermore, the method also includes: the user-preferred heating mode includes a direct heat preservation mode and a boiling-then-heat preservation mode; when the user-preferred heating mode is the direct heat preservation mode, if it is determined that the water temperature changes abruptly, the heating module is controlled to heat the water in the pot body assembly using the direct heat preservation mode; when the user-preferred heating mode is the boiling-then-heat preservation mode, if it is determined that the water temperature changes abruptly, the heating module is controlled to heat the water in the pot body assembly using the boiling-then-heat preservation mode.

[0009] Furthermore, the water dispenser has no water quality detection device, but it has direct heat preservation and heating commands and boiling followed by heat preservation and heating commands. When a sudden change in water temperature is detected, the heating module is controlled to heat the water in the pot assembly based on at least one nearby user-selected heating command.

[0010] Furthermore, the method also includes: obtaining the user's preferred heating mode includes: obtaining the initial heating mode selected by the user after the first water addition; and storing the initial heating mode as the user's preferred heating mode.

[0011] Furthermore, the method also includes: after storing the initial heating mode as the user's preferred heating mode, it includes: obtaining multiple subsequent heating modes actively selected by the user multiple times; and updating the user's preferred heating mode based on the subsequent heating modes.

[0012] Furthermore, the method also includes: updating the user's preferred heating mode based on the subsequent heating mode includes: counting the number of times the direct heat preservation mode and the boiling-then-heat preservation mode are selected in the subsequent heating modes respectively; when either the direct heat preservation mode or the boiling-then-heat preservation mode reaches a preset number of selections, and the difference between the selections of the other mode and the preset number of selections reaches a preset number difference, the subsequent heating mode corresponding to the selections reaching the preset number of selections is taken as the user's preferred heating mode.

[0013] Furthermore, the method also includes: when the water temperature changes abruptly, confirming the time interval since the last heating was performed; when the time interval is longer than a preset time, prompting the user to reselect the heating mode; obtaining the heating mode reselected by the user, and using the reselected heating mode as the user's preferred heating mode.

[0014] Furthermore, the method also includes determining whether the water temperature has abruptly changed, which includes: acquiring sampled values ​​of the water temperature based on time series; determining the temperature change state of the water temperature based on the sampled values; and determining whether the water temperature has abruptly changed based on the temperature change state.

[0015] Furthermore, the method further includes: determining the temperature change state of the water temperature based on the sampled values ​​includes: acquiring the sampled values ​​within two or more consecutive time periods; determining whether there are identical sampled values ​​within any pair or more adjacent time periods; and determining that the temperature change state is a sudden change state when there are no identical sampled values ​​within two adjacent time periods.

[0016] Furthermore, the method also includes: determining whether there are identical sampled values ​​in any pair or more adjacent time periods includes: determining whether the absolute value of the difference between any sampled value in the later time period and any sampled value in the previous time period is greater than a preset value; when the absolute value of the difference between any sampled value in the later time period and any sampled value in the previous time period is greater than the preset value, the temperature change state is determined to be a sudden change state.

[0017] Furthermore, to achieve the second objective mentioned above, a water dispenser is also provided, comprising: a pot body assembly for storing water; a heating module for heating the water in the pot body assembly; and a temperature measuring module for detecting the water temperature in the pot body assembly. The water dispenser also includes a processor, a memory, and execution instructions stored in the memory, wherein the execution instructions are configured to enable the water dispenser to perform the heating control method of the water dispenser described above when executed by the processor.

[0018] In this application, the water temperature inside the cooker assembly is monitored to determine if a sudden temperature change has occurred. When such a change occurs, the controller acquires the user's preferred heating mode and controls the heating module to heat the water inside the cooker assembly according to this mode. A sudden temperature change indicates that the user has added water. Based on the user's preferred heating mode, the controller determines the water quality and heats it accordingly. This ensures that if the user adds tap water, it is immediately boiled, preventing the user from drinking unboiled water. Furthermore, if the user prefers to add drinking water, the system immediately keeps the water warm, eliminating waiting time.

[0019] The above control methods solve the problems of users drinking unboiled water after adding it or needing to boil the water and then cool it to the desired temperature after adding drinking water. Attached Figure Description

[0025] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0027] As described in the background section, existing water dispensers without water quality testing devices can lead to users drinking unboiled water after adding it. Most water dispensers currently on the market do not solve this problem. Some dispensers simply boil the water or keep it at a set temperature after adding it. With the boiled water option, users adding water that is ready to drink immediately must wait for the water to cool to the desired temperature before drinking. With the keep-warm option, users may add unboiled water, resulting in them drinking unboiled water.

[0028] To address the aforementioned technical problems, this application adopts the following technical solution:

[0029] A heating control method for a water dispenser, applicable to water dispensers, such as... Figure 1As shown, the water dispenser includes: an upper cover assembly 11, a control assembly 12, a water outlet assembly 13, a heating module 14, a pot body assembly 15, a bottom cover assembly 16, and a temperature measuring module 17.

[0030] The function of the control component 12 is to control the operation logic of the heating module 14, and also includes providing power and user interaction functions;

[0031] The function of the water outlet component 13 is to drain the water from the pot and inject it into the container required by the user.

[0032] The function of the heating module 14 is to convert the input electrical energy into heat energy and transfer it to the water in the kettle;

[0033] The function of the temperature measuring module 17 is to detect the water temperature inside the water dispenser and convert it into an analog signal, which is then transmitted to the control component 12.

[0034] The structural components of the top cover assembly 11, the pot body assembly 15, and the base assembly 16 function to support the above functional modules, and provide the shape and user interface.

[0035] Figure 2 This is a flowchart of a water dispenser heating control method according to an embodiment of the present invention, referred to [reference]. Figure 1 The water dispenser heating control method may include the following steps:

[0036] S10. Obtain the water temperature inside the pot body assembly. As an exemplary embodiment, the temperature measuring module detects the water temperature inside the water dispenser and converts the measured water temperature into an analog signal, which is then transmitted to the control component. The water temperature inside the pot body assembly is obtained in this way.

[0037] S20. Determine if the water temperature has changed abruptly. Normally, when a water dispenser is in heat preservation or heating mode, the water temperature fluctuates little. However, after the user adds water, the water temperature fluctuates significantly compared to the heat preservation or heating mode. After the user adds water, the temperature inside the pot assembly may change abruptly, either rising or falling suddenly. Therefore, determining whether the user has added water can help determine if a sudden temperature change has occurred within the pot assembly. As an exemplary embodiment, the term "sudden temperature change" depends on the water dispenser's heat preservation accuracy; it can be more than 3°C greater than the accuracy, or more than 2°C greater than the temperature change of water under normal conditions. Optionally, the sudden temperature change can be 3-5°C. When a sudden temperature change occurs, proceed to step S30. When no sudden temperature change occurs, return to step S10. S30. Control the heating module to heat the water inside the pot assembly according to the user's preferred heating mode.

[0038] The user-preferred heating mode may include a first heating mode and a second heating mode. As an example, the first heating mode may be a direct heat preservation mode, and the second heating mode may be a boil-then-heat preservation mode. When the user selects the direct heat preservation heating command, the heating mode is the direct heat preservation mode; when the user selects the boil-then-heat preservation heating command, the heating mode is the boil-then-heat preservation mode. As an example, upon detecting a water addition action, the heating module is controlled to heat the water in the cooker assembly according to the user-preferred heating mode.

[0039] Based on the above-described water dispenser control method, after a sudden change in water temperature is detected, the heating module is controlled to heat the water in the boiler assembly according to the user's preferred heating mode. Specifically, if the user's preferred heating mode is boiling followed by keeping warm, the boiling-then-keeping operation is executed; if the user's preferred heating mode is direct keeping warm, the direct keeping operation is executed. This solves the problem of users adding unboiled water and then drinking unboiled water, or adding drinking water and then boiling it before cooling it to the desired temperature.

[0040] As an exemplary embodiment, the water dispenser has no water quality detection device and features direct heat preservation and heating commands, as well as commands to boil and then heat again. When a sudden change in water temperature is detected, the heating module is controlled to heat the water in the boiler assembly based on at least one of the nearest user-selected heating commands. This allows for different heating modes for drinking water and tap water, without the need for a water quality detector. The direct heat preservation mode corresponds to the user-selected direct heat preservation mode, and the boil-and-then-heat preservation mode corresponds to the user-selected boil-and-then-heat preservation mode. Different heating methods are applied to drinking water and tap water based on these modes, solving the problems of users adding tap water before it has been boiled, resulting in drinking unboiled water, or adding drinking water requiring boiling and then cooling to the desired temperature.

[0041] Controlling the heating module to heat the water inside the cooker body according to the user's preferred heating mode may include the following steps:

[0042] Obtaining user-preferred heating modes may include the following steps:

[0043] Get the water filling mode selected by the user after the first water filling, perform the heating operation according to the user's first heating mode, and store the user's first heating mode as the user's preferred heating mode.

[0044] When the user does not actively select a subsequent heating mode, the water temperature inside the cooker body assembly is obtained; it is determined whether the water temperature changes abruptly; when the water temperature changes abruptly, the user's preferred heating mode is obtained; and the heating module is controlled to heat the water inside the cooker body assembly according to the user's preferred heating mode. For details, please refer to the description of steps S10-S30 in the above embodiments.

[0045] For example, when a user selects the direct heat preservation mode after adding water for the first time, this selected mode is stored as the user's preferred heating mode. Since the heating mode selected during the first water addition is directly related to the water quality, when the user adds drinking water, they will select the direct heat preservation mode. Therefore, the user's preferred heating mode can be used as a basis for judging the user's water quality.

[0046] After the water addition action is confirmed, the heating module is controlled to heat the water in the cooker body according to the user's preferred heating mode. When the user adds tap water, the boiling-then-keep-warm mode is selected; when the user adds drinking water, the direct-warm-warm heating command is selected. Therefore, if the user selects the direct-warm-warm heating command a sufficient number of times, and the number of times it is selected far exceeds the boiling-then-warm-warm heating command, it can be assumed that the user's preferred heating command is the direct-warm-warm heating command, the user's preferred heating mode is the direct-warm-warm mode, and the user's preferred water quality is drinking water. Similarly, if the user selects the boiling-then-warm-warm heating command a sufficient number of times, and the number of times it is selected far exceeds the direct-warm-warm heating command, it can be assumed that the user's preferred heating command is the boiling-then-warm-warm heating command, the user's preferred heating mode is the boiling-then-warm-warm mode, and the user's preferred water quality is tap water. When the user actively selects a subsequent heating mode, the system acquires multiple selections of subsequent heating modes, counts the number of times the direct-warm-warm mode and the boiling-then-warm-warm mode are selected, and determines whether the number of times the direct-warm-warm mode is selected has reached a preset number.

[0047] When the direct heat preservation mode has been selected a preset number of times:

[0048] Determine whether the difference between the number of times the direct heat preservation mode is selected and the number of times the heat preservation mode is selected after boiling reaches the preset value;

[0049] When the difference between the number of times the direct heat preservation mode is selected and the number of times the heat preservation mode is selected after boiling reaches a preset value, the direct heat preservation mode will be stored as the user's preferred heating mode.

[0050] When the difference between the number of times the direct heat preservation mode is selected and the number of times the heat preservation mode is selected after boiling does not reach the preset value, the system continues to acquire multiple subsequent heating modes actively selected by the user.

[0051] If the number of times the direct heat preservation mode is selected has not reached the preset number, continue to obtain multiple subsequent heating modes actively selected by the user.

[0052] Determine whether the preset number of times the boil-and-keep-warm function has been selected has been reached;

[0053] When the number of times the boiling-after-keep-warm mode is selected reaches the preset value, it is determined whether the difference between the number of times the boiling-after-keep-warm mode is selected and the number of times the direct-warm-warm mode is selected reaches the preset value.

[0054] When the difference between the number of times the boiling-then-keep-warm mode is selected and the number of times the direct-warm-warm mode is selected reaches a preset value, the boiling-then-warm-warm mode will be stored as the user's preferred heating mode.

[0055] If the difference between the number of times the user selects the "keep warm after boiling" mode and the number of times the user selects the "keep warm directly" mode does not reach the preset difference value, the system will continue to acquire multiple subsequent heating modes actively selected by the user.

[0056] If the number of times the option to keep warm after boiling is not reached, the system continues to acquire multiple subsequent heating modes actively selected by the user.

[0057] For example, during long-term use, the heating mode selected by the user is recorded based on their usage habits. For instance, if the direct heat preservation mode is selected m times out of n uses, then the number of times the direct heat preservation mode is selected is m, where nm times represents the number of times the boiling heat preservation mode is selected. When it is determined that m is greater than a first preset number, i.e., m reaches the preset value, it indicates that the user has selected the direct heat preservation mode multiple times during heating. Since the direct heat preservation mode is considered the user's preferred heating mode, it can be assumed that the user habitually adds drinking water, and the direct heat preservation operation will be performed on drinking water in subsequent heating operations.

[0058] When a user reactivates a machine after it has been inactive for an extended period:

[0059] The system prompts the user to select a new heating mode, sets the selected mode as the user's preferred heating mode, and performs the heating operation according to the preferred heating mode.

[0060] For example, when a user restarts the machine after a long period of inactivity, they may have selected a new water quality. The water quality determined by the user's preferred heating mode may not be suitable for the new water addition, potentially leading to situations where the user adds unboiled tap water or needs to boil and then cool drinking water. Therefore, when restarting the machine after a long period of inactivity, if the user's previous preferred heating mode was direct heat preservation, adding tap water upon restarting will boil the water using the user's newly selected boil-then-heat preservation mode, thus resolving the issue of drinking unboiled tap water. Similarly, if the user's previous preferred heating mode was boil-then-heat preservation, adding drinking water upon restarting will keep the drinking water at the target temperature using the user's newly selected direct heat preservation mode, thus resolving the issue of needing to boil and then keep the drinking water warm after adding it.

[0061] Based on the above method, the problems of users drinking unboiled water after adding raw water or needing to boil water and then cool it to the desired temperature after adding drinking water have been solved.

[0062] For example, as described in the background art, the most common solution for detecting whether water has been added is to use a water level electrode to detect the water level. This application proposes an optimized detection method, namely, a method that detects water addition by detecting temperature changes. As an exemplary embodiment, water temperature samples can be acquired based on a time sequence; the temperature change state of the water temperature can be determined based on the sample values; and whether a sudden change in water temperature has occurred can be determined based on the temperature change state. After obtaining the sample values ​​ordered in time sequence, the successively acquired temperature values ​​can be compared. When there is a significant change in the temperature values, a sudden change in water temperature can be determined. Alternatively, the temperature change rate over multiple time periods can be calculated based on the time-series sample values, and a significant change in the temperature change rate can be determined to indicate a sudden change in water temperature. In the exemplary embodiment, the comparison of sample values ​​can be used as an example for illustration:

[0063] Water temperature is sampled over two or more consecutive time periods, with at least one sampled value existing within each time period. The water temperature change state is determined based on the sampled values. After obtaining the sampled values ​​sorted by time, the acquired temperature values ​​are compared. When the comparison value shows a significant change, the water temperature is considered to be in a changing state, and a sudden change in water temperature is determined based on this change state.

[0064] After obtaining water temperature samples based on time sequence, it is determined whether any pair or more adjacent time periods contain identical samples. For example, during the heat preservation phase, water temperature sampling may result in identical samples within any pair or more adjacent time periods. However, after adding water, due to the significant temperature difference between the added water and the water temperature inside the cooker assembly, identical samples will not exist within any pair or more adjacent time periods. Therefore, if it is determined that no identical samples exist within any pair or more adjacent time periods, it is determined that a sudden change in water temperature has occurred within the cooker assembly.

[0065] For example, during the heat preservation process, when the sampling frequency is sufficiently high, there may be instances where different sampling values ​​exist within one or more pairs of adjacent time periods. Therefore, to address this situation, when performing a water-addition operation at a sufficiently high sampling frequency, the temperature change during the water-addition phase is more pronounced compared to the heating or cooling phases because the temperature of the added water differs significantly from the temperature inside the cooker assembly. Based on this, this application proposes another preferred method for determining the water temperature change state.

[0066] Based on the time-series acquisition of water temperature sampling values, the absolute value of the difference between any sampling value in a later time period and any sampling value in a previous time period is compared with a water-adding action threshold. When the absolute value of the difference between any sampling value in a later time period and any sampling value in a previous time period is greater than the water-adding action threshold, it is determined that a sudden change in water temperature has occurred. The water-adding action threshold is determined by the heat preservation accuracy and can be 3-5℃.

[0067] To more accurately determine the difference between the heating or cooling phases during the water addition and heat preservation processes, the method described above can be further refined by determining the number of temperature changes that occur when the absolute value of the difference between any sampled value in a later time period and any sampled value in a previous time period exceeds a preset value. The number of temperature changes can be determined based on factors such as the remaining water in the bottle, the water temperature, and the response speed of the temperature measuring module. Generally, 3-5 changes are considered.

[0068] For example, a water dispenser provided in this application includes: Figure 1 The water dispenser shown includes: a top cover assembly 11, a control assembly 12, a water dispensing assembly 13, a heating module 14, a cooker body assembly 15, a bottom cover assembly 16, a temperature measuring module 17, and also includes, for example, Figure 3 The processor, memory, and execution instructions stored in the memory are shown. These instructions are configured to enable the water dispenser to perform the aforementioned heating control method when executed by the processor. Optionally, a memory and bus are also included.
