Description

Technical Field

[0001] This invention relates to the field of drinking water equipment technology, specifically providing a control method for a water dispenser and a water dispenser. Background Technology

[0002] Water dispensers are everyday drinking water facilities. The water tanks of water dispensers are prone to bacterial growth. In addition, the temperature of the heating chamber of instant water dispensers with preheating function is generally set at 40-50℃. At this temperature, a favorable environment for bacterial growth is provided. With the use of water dispensers, a large number of bacteria will grow in the heating chamber. If the water tank and heating chamber of the water dispenser are not sterilized, it will pose a threat to the health of users.

[0003] Existing water dispensers cannot sterilize the water tank and heating chamber in a timely manner, thus failing to keep the water tank and heating chamber clean during use, resulting in a poor user experience.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that existing water dispensers cannot sterilize the water tank and heating chamber in a timely manner, thus failing to keep the water tank and heating chamber clean during use, resulting in a poor user experience.

[0006] In a first aspect, the present invention provides a control method for a water dispenser, the water dispenser including a water tank, a heating assembly, a connecting pipe, and a water dispensing component. The heating assembly has a heating chamber and the heating chamber is in communication with the water tank. The connecting pipe enables a circulating water path to be formed between the water tank and the heating chamber. The water dispenser also includes a water pump disposed on the connecting pipe, the water pump being used to allow water in the heating chamber to flow between the circulating water paths. The water dispenser has a water dispensing mode and a sterilization mode. When the water dispenser activates the sterilization mode, water in the water tank is allowed to enter the heating chamber, and hot water in the heating chamber is allowed to flow between the circulating water paths to sterilize the water dispenser. The control method includes: obtaining the running time T of the water dispenser since the last execution of the sterilization mode; obtaining the water level L in the water tank; and selectively activating the sterilization mode based on the running time T and the water level L.

[0007] In the preferred embodiment of the above control method, the specific steps of "selectively activating the sterilization mode according to the running time T and the water level L" include: comparing the running time T with a first preset time T1 and a second preset time T2 respectively; comparing the water level L with a first preset water level L1; and selectively activating the sterilization mode according to the comparison result; wherein the first preset time T1 is less than the second preset time T2.

[0008] In the preferred embodiment of the above control method, the specific steps of "selectively activating the sterilization mode according to the comparison results" include: if T≥T2 and L≥L1, then the sterilization mode is activated.

[0009] In the preferred embodiment of the above control method, the specific steps of "selectively activating the sterilization mode according to the comparison results" include: if T1≤T<T2 and L≥L1, then further determine whether the current time is during the peak water usage period based on the historical usage data of the water dispenser; if the determination result is "no", then activate the sterilization mode.

[0010] In a preferred embodiment of the above control method, after activating the sterilization mode, the control method further includes: acquiring the water temperature t in the circulating water circuit; and selectively terminating the sterilization mode based on the water temperature t.

[0011] In the preferred embodiment of the above control method, the specific steps of "selectively ending the sterilization mode according to the water temperature t" include: comparing the water temperature t with a preset water temperature t0; if t ≥ t0, then ending the sterilization mode; if t < t0, then not ending the sterilization mode.

[0012] In the preferred embodiment of the above control method, the specific steps of "selectively activating the sterilization mode based on the comparison results" include:

[0013] If T < T1, the sterilization mode will not be activated.

[0014] In the preferred embodiment of the above control method, the step of "selectively activating the sterilization mode according to the comparison result" further includes: if the judgment result is "yes", then the sterilization mode is not activated.

[0015] In a preferred embodiment of the above control method, the water dispenser further includes an antibacterial component disposed in the water tank, and the control method further includes: comparing the water level L with a second preset water level L2; if L≥L2, then activating the antibacterial component.

[0016] In a second aspect, the present invention provides a water dispenser including a controller configured to perform the control method described above.

[0017] When adopting the above technical solution, the control method of the present invention includes: obtaining the running time T of the water dispenser since the last execution of the sterilization mode; obtaining the water level L in the water tank; and selectively activating the sterilization mode based on the running time T and the water level L. With this setting, on the one hand, the water dispenser can be selectively activated to perform the sterilization mode based on the running time since the last execution of the sterilization mode and the water level in the water tank. On the other hand, this allows for timely sterilization of the water tank and heating chamber, preventing bacterial growth in the water tank and heating chamber that could threaten the user's health, thus keeping the water tank and heating chamber clean during use. Furthermore, it prevents the sterilization mode from being activated when the water level in the tank is insufficient, avoiding energy waste and improving the user experience.

[0018] Furthermore, the specific steps of "selectively activating the sterilization mode based on the running time T and the water level L" include: comparing the running time T with a first preset time T1 and a second preset time T2 respectively; comparing the water level L with a first preset water level L1; and selectively activating the sterilization mode based on the comparison results; wherein the first preset time T1 is less than the second preset time T2. Through this setting, the cleanliness of the water tank and heating chamber is reflected based on the running time of the water dispenser since the last sterilization mode execution. On the one hand, this allows for timely sterilization of the water dispenser, while ensuring sufficient water in the tank when the sterilization mode is executed; on the other hand, when the cleanliness of the water tank and heating chamber is high, the sterilization mode is not activated, thus saving energy and improving the user experience.

[0019] Furthermore, the specific steps of "selectively activating the sterilization mode based on the comparison results" include: if T≥T2 and L≥L1, then the sterilization mode is activated. With this setting, when the water dispenser's running time T since the last sterilization exceeds the second preset time T2, it indicates that the time since the last sterilization is sufficiently long, and the cleanliness level in the water tank and heating chamber is low. At this point, as long as the water level L in the tank exceeds the minimum water volume L1 required for sterilization, the sterilization mode is activated to sterilize the water tank and heating chamber, keeping them clean during use and preventing bacterial growth that could affect the user's drinking water health.

[0020] Furthermore, the specific steps of "selectively activating the sterilization mode based on the comparison results" include: if T1≤T<T2 and L≥L1, then further determine whether the current time is during a peak water usage period based on the historical usage data of the water dispenser; if the determination result is "no", then activate the sterilization mode. With this setting, when the water dispenser's operating time T since the last sterilization operation reaches the first preset time T1 but does not exceed the second preset time T2, it indicates that although the cleanliness level in the water tank and heating chamber is not very high, it is not very low either. If the water level in the tank exceeds the first water level L1 at this time, further determining whether it is during a peak water usage period can prevent the water dispenser from executing the sterilization mode during peak water usage periods, thereby avoiding the water temperature in the tank rising during sterilization and affecting normal user operation.

[0021] Furthermore, after activating the sterilization mode, the control method of the present invention further includes: acquiring the water temperature t in the circulating water circuit; and selectively terminating the sterilization mode based on the water temperature t. This setting ensures that the water temperature in the circulating water circuit is sufficient for high-temperature sterilization, while also preventing excessively long sterilization times from affecting normal user operation.

[0022] Furthermore, the specific steps of "selectively ending the sterilization mode based on water temperature t" include: comparing the water temperature t with the preset water temperature t0; if t ≥ t0, then ending the sterilization mode; if t < t0, then not ending the sterilization mode. With this setting, when the water temperature t exceeds the preset water temperature t0, it indicates that the water temperature during sterilization is high enough to perform high-temperature sterilization of the circulating water circuit. Ending the sterilization mode at this time saves energy and avoids excessively long sterilization times that could affect normal user operation. When the water temperature t has not yet reached t0, it indicates that the water temperature in the circulating water circuit is too low to perform high-temperature sterilization of the circulating water circuit; in this case, the sterilization mode is not ended.

[0023] Furthermore, the specific steps of "selectively activating the sterilization mode based on the comparison results" include: if T < T1, then the sterilization mode is not activated. With this setting, if the running time T has not yet reached the first preset time T1, it indicates that the cleanliness level in the water tank and heating chamber is relatively high. In this case, the sterilization mode is not activated, thereby saving energy and further improving the user experience.

[0024] Furthermore, the step of "selectively activating the sterilization mode based on the comparison results" also includes: if the judgment result is "yes," then the sterilization mode is not activated. With this setting, if the judgment result is "yes," it indicates that the current time is a peak water usage period. In this case, not activating the sterilization mode avoids affecting the user's normal use when the water dispenser is in sterilization mode. It also prevents the water temperature in the tank from rising due to sterilization, thus affecting the user's ability to drink room temperature water, further improving the user experience.

[0025] Furthermore, the water dispenser of the present invention also includes an antibacterial component disposed within the water tank, and the control method of the present invention further includes: comparing the water level L with a second preset water level L2; if L≥L2, then activating the antibacterial component. With this configuration, if the water level L in the water tank reaches the second preset water level L2, it indicates that water has begun to enter the water tank. At this time, activating the antibacterial component facilitates the inhibition of bacteria in the water in the tank, reducing bacterial growth and further enhancing the user experience.

[0026] Furthermore, the water dispenser provided by the present invention, based on the above technical solution, possesses the technical effects of the above control method due to the adoption of the above control method. Compared with the water dispenser before the improvement, the water dispenser of the present invention can sterilize the water tank and heating chamber in a timely manner, making the water tank and heating chamber of the water dispenser cleaner during use and providing a better user experience.

[0033] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0034] It should be noted that in the description of this invention, terms such as "upper," "lower," "inner," and "bottom," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, it should not be construed as a limitation of this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0036] Please see Figure 1 As shown, Figure 1 This is a schematic diagram of the connection structure of the water dispenser of the present invention.

[0037] like Figure 1 As shown, the water dispenser of the present invention includes a water tank 1, a heating component 2, a connecting pipe and a water outlet component. The heating component 2 has a heating chamber 21 and the heating chamber 21 is connected to the water tank 1. The connecting pipe includes a first connecting pipe 31 and a second connecting pipe 32. The first connecting pipe 31 and the second connecting pipe 32 enable a circulating water path to be formed between the water tank 1 and the heating chamber 21.

[0038] The water dispenser also includes a water pump 311 installed on the first connecting pipe 31. The water pump 311 is used to make the water in the heating chamber 21 flow between the circulating water paths. A first control valve 312 is also installed on the first connecting pipe 31.

[0039] The water outlet component includes a first water outlet pipe 41 and a second water outlet pipe 42. The first water outlet pipe 41 is connected to the water tank 1. A first water outlet valve 411 is installed on the first water outlet pipe 41. The first water outlet pipe 41 is connected to the ambient temperature water outlet 412. When the first water outlet valve 411 is opened, the water in the water tank 1 flows along the first water outlet pipe 41 and flows out from the ambient temperature water outlet 412.

[0040] One end of the second water outlet pipe 42 is connected to the heating chamber 21 via the first connecting pipe 31, and the other end of the second water outlet pipe is connected to the hot water outlet 424. A rapid heating component 421 and a second water outlet valve 423 are provided on the second water outlet pipe 42. The rapid heating component 421 can rapidly heat the water entering the second water outlet pipe 42, and the second water outlet valve 423 can allow the water in the rapid heating component 421 to flow out from the hot water outlet 424. A second control valve 422 is also provided on the second water outlet pipe 42, and the second control valve 422 is located at the front end of the rapid heating component 421.

[0041] It should be noted that, in practical applications, those skilled in the art can configure the heating component 2 as a resistance heating structure, or as a rapid heating structure, or as an electromagnetic heating structure, etc. Such adjustments and changes to the specific heating method of the heating component 2 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0042] Preferably, the heating component 2 is configured as a resistance heating structure.

[0043] It should be noted that in practical applications, the arrangement is not limited to placing the water pump 311 and the first control valve 312 on the first connecting pipe 31. For example, both the water pump 311 and the first control valve 312 can be placed on the second connecting pipe 32. Alternatively, one of the water pump 311 and the first control valve 312 can be placed on the first connecting pipe 31, and the other can be placed on the second connecting pipe 32, and so on. Such adjustments and changes to the specific positions of the water pump 311 and the first control valve 312 do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention. Of course, it is preferable to place the water pump 311 and the first control valve 312 on the first connecting pipe 31.

[0044] The water dispenser of the present invention has a water dispensing mode and a sterilization mode. For example, when the water dispenser is in the water dispensing mode, the first control valve 312 is closed and the second control valve 422 is open. When room temperature water is needed, the second water outlet valve 423 is closed and the first water outlet valve 411 is opened, so that the water in the water tank 1 flows out from the first water outlet pipe 41 at the room temperature water outlet 412 under the action of gravity, thus realizing room temperature water dispensing. When hot water is needed, the first water outlet valve 411 is closed and the second water outlet valve 423 is opened, and the water pump 311 is turned on, so that the water in the heating chamber 21 enters the rapid heating component 421 and is rapidly heated, so that the hot water flows out from the hot water outlet 424, thus realizing hot water dispensing.

[0045] With this setup, the presence of heating component 2 will raise the water temperature in heating chamber 21 to a certain level. When hot water is dispensed, the hot water in heating chamber 21 will be heated again by rapid heating component 421 to raise the temperature to the set temperature, thereby shortening the heating time, increasing the heating rate, and further enhancing the user experience.

[0046] When the water dispenser starts the sterilization mode, the second control valve 422 is closed, and the first control valve 312 and the water pump 311 are opened. The water pump 311 enables the water in the water tank 1 to enter the heating chamber 21 and makes the hot water in the heating chamber 21 flow between the circulating water circuits to sterilize the water dispenser.

[0047] It should be noted that in practical applications, when the water dispenser starts the sterilization mode, the second control valve 422 can be closed directly, and the first control valve 312 and the water pump 311 can be opened, so that the water in the water tank 1 circulates in the circulating water path, and the heating component 2 heats the water flowing through the heating chamber 21. Alternatively, it can be set so that the heating component 2 heats the water flowing through the heating chamber 21 to the set temperature first, and then the second control valve 422 is closed, and the first control valve 312 and the water pump 311 are opened, so that the hot water in the heating chamber 21 circulates in the circulating water path, and at the same time, the heating component 2 heats the water flowing through the heating chamber 21 until it is heated to the temperature required for sterilization, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0048] Preferably, the heating component 2 first heats the water flowing through the heating chamber 21 to a set temperature, then the second control valve 422 is closed, and the first control valve 312 and the water pump 311 are opened, so that the hot water in the heating chamber 21 circulates in the circulating water circuit. At the same time, the heating component 2 heats the water flowing through the heating chamber 21.

[0049] It should be noted that, in practical applications, those skilled in the art can install a temperature detection component, such as a thermometer or temperature sensor, inside the heating chamber 21. When the temperature detection component detects that the water temperature inside the heating chamber 21 has reached the set temperature, it can close the second control valve 422 and open the first control valve 312 and the water pump 311, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0050] For example, such as Figure 1 As shown, a first temperature detection component 211 is provided inside the heating chamber 21. The first temperature detection component 211 is used to detect the water temperature inside the heating chamber 21.

[0051] With this setup, the water temperature in the heating chamber 21 is first raised to a certain level, and then the water pump 311 is turned on to circulate the water between the circulation paths. This reduces the working time of the water pump 311, thereby saving energy and further improving the user experience.

[0052] For example, when the water temperature in the heating chamber 21 reaches 80°C, the second control valve 422 is closed, and the first control valve 312 and the water pump 311 are opened. The water pump 311 transports the water in the heating chamber 21 to the water tank 1, and then sends the water in the water tank 1 back to the heating chamber 21. The hot water heated by the heating component 2 is then transported to the water tank 1, so that the hot water flows between the circulating water paths to sterilize the water tank 1 and the heating chamber 21.

[0053] See next Figure 2 , Figure 2 This is a flowchart of the control method of the present invention.

[0054] like Figure 2 As shown, the control method of the present invention includes:

[0055] S1000: Get the running time T of the water dispenser since the last time it executed the sterilization mode;

[0056] S2000: Obtain the water level L in water tank 1;

[0057] S3000: Selectively activates sterilization mode based on runtime T and water level L.

[0058] With this setting, on the one hand, the water dispenser can selectively activate the sterilization mode based on the running time since the last sterilization mode and the water level in water tank 1. On the other hand, it can sterilize water tank 1 and heating chamber 21 in a timely manner, keeping them clean during use and preventing bacterial growth that could threaten the user's health. On the other hand, it can prevent the sterilization mode from activating when the water level in water tank 1 is insufficient, avoiding energy waste and improving the user experience.

[0059] It should be noted that, in practical applications, those skilled in the art can directly observe the amount of water in the water tank 1 to obtain the water level in the water tank 1, or they can obtain the water level in the water tank 1 by setting a water level detection component in the water tank 1, etc. Such adjustments and changes to the specific method of obtaining the water level in the water tank 1 do not deviate from the principle and scope of the present invention, and should all be included within the protection scope of the present invention.

[0060] Preferably, such as Figure 1 As shown, a water level detection component 11 is installed inside the water tank 1 to obtain the water level inside the water tank 1.

[0061] It should be noted that, in practical applications, those skilled in the art can configure the water level detection component 11 as a water level sensor, or as a liquid level gauge, etc. Such adjustments and changes to the specific configuration type of the water level detection component 11 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0062] Preferably, the water level detection component 11 is configured as a water level sensor.

[0063] See next Figure 3 , Figure 3 This is a flowchart of an embodiment of the control method of the present invention.

[0064] Preferably, such as Figure 3 As shown, the specific steps for "selectively activating the sterilization mode based on the runtime T and water level L" include:

[0065] S3100: Compare the runtime T with the first preset runtime T1 and the second preset runtime T2 respectively;

[0066] S3200: Compare the water level L with the first preset water level L1;

[0067] S3300: Based on the comparison results, selectively activate the sterilization mode;

[0068] The first preset duration T1 is less than the second preset duration T2.

[0069] By using this setting, the cleanliness level of the water tank 1 and heating chamber 21 can be predicted based on the running time of the water dispenser since the last sterilization mode. On the one hand, if the running time since the last sterilization mode is long, it indicates that the cleanliness level of the water tank 1 and heating chamber 21 may not be high, and the water dispenser can be sterilized in time. At the same time, it can ensure that there is enough water in the water tank 1 when the water dispenser is in sterilization mode. On the other hand, if the running time since the last sterilization mode is short, it indicates that the cleanliness level of the water tank 1 and heating chamber 21 is high. In this case, the sterilization mode is not activated, which helps to save energy and improve the user experience.

[0070] It should be noted that in practical applications, the comparison is not limited to directly comparing the running time T with the first preset duration T1 and the second preset duration T2 as described above. For example, the difference between the running time T and the preset duration can be calculated first, and then compared with the first and second preset values. Alternatively, the ratio of the running time T to the preset duration can be calculated first, and then compared with the first and second preset values, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should all be included within the protection scope of this invention. Of course, it is preferable to directly compare the running time T with the first preset duration T1 and the second preset duration T2.

[0071] It should also be noted that in practical applications, the comparison is not limited to directly comparing the water level L with the first preset water level L1 as described above. For example, the difference between the water level L and the first preset water level L1 can be calculated first, and then compared with the preset value. Alternatively, the ratio between the water level L and the first preset water level L1 can be calculated first, and then compared with the preset value, etc. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should all be included within the protection scope of this invention. Of course, it is preferable to directly compare the water level L with the first preset water level L1.

[0072] Preferably, such as Figure 3 As shown, the specific steps for "selectively activating the sterilization mode based on the comparison results" include:

[0073] S3310: If T≥T2 and L≥L1, then start the sterilization mode.

[0074] With this setting, when the running time T of the water dispenser since the last sterilization mode exceeds the second preset time T2, it means that the time since the last sterilization of the water dispenser has been long enough, and the cleanliness level in the water tank 1 and heating chamber 21 is low. At this time, as long as the water level L in the water tank 1 exceeds the minimum water volume required for sterilization, i.e., the first preset water level L1, the sterilization mode is activated to sterilize the water tank 1 and heating chamber 21, thereby keeping the water tank 1 and heating chamber 21 clean during use and preventing the growth of bacteria in the water tank 1 and heating chamber 21 from affecting the user's drinking water health.

[0075] Preferably, such as Figure 3 As shown, the specific steps for "selectively activating the sterilization mode based on the comparison results" include:

[0076] S3320: If T1≤T<T2 and L≥L1, then further determine whether the current time is during the peak water usage period based on the historical usage data of the water dispenser;

[0077] If the judgment result is "no", then the sterilization mode will be activated.

[0078] With this setting, when the water dispenser reaches the first preset time T1 but does not exceed the second preset time T2 since the last sterilization run, it means that although the cleanliness of the water tank 1 and heating chamber 21 is not very high, its cleanliness will not threaten the user's health. If the water level in the water tank 1 exceeds the first water level L1, it is further determined whether it is a peak water usage period. This can prevent the water dispenser from executing the sterilization mode during peak water usage periods, thereby avoiding the water temperature in the water tank 1 from rising during sterilization and affecting the user's normal use.

[0079] It should be noted that, in practical applications, those skilled in the art can set the specific values ​​of the first preset duration T1, the second preset duration T2, and the first preset water level L1 based on experiments or experience.

[0080] It should be noted that those skilled in the art can obtain peak water usage periods based on historical usage data of the water dispenser, or they can obtain peak water usage periods based on the user-defined peak water usage time range, such as setting 8:00 to 18:00 as peak water usage periods, i.e., frequent water usage during the day and less water usage at night, etc. Such adjustments and changes to the method of obtaining peak water usage periods do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0081] Preferably, peak water usage periods are obtained based on historical usage data of the water dispenser. For example, a day is divided into 24 time periods, each lasting one hour. If the number of water usages exceeds 10 times within one hour, that time period is recorded as a peak water usage period.

[0082] Preferably, the control method of the present invention further includes:

[0083] If the judgment result is "yes", the sterilization mode will not be activated.

[0084] If the current time happens to be during peak water usage hours, the sterilization mode will not be activated immediately. It will be activated after the peak water usage hours have ended. This will prevent the sterilization process from affecting the normal use of the water dispenser and will also prevent the water tank 1 from becoming too hot due to sterilization, thus affecting the user's ability to drink room temperature water.

[0085] It should be noted that if the current time is close to the peak water usage period, meaning the peak water usage period will soon begin, the sterilization mode will not be activated at this time to prevent the water tank 1 from becoming too hot due to sterilization, which could affect the user's ability to drink room temperature water.

[0086] Preferably, such as Figure 3 As shown, the specific steps for "selectively activating the sterilization mode based on the comparison results" include:

[0087] S3330: If T < T1, then the sterilization mode will not be activated.

[0088] With this setting, if the running time T has not yet reached the first preset time T1, it means that the cleanliness level in the water tank 1 and heating chamber 21 is relatively high. At this time, the sterilization mode is not activated, which helps to save energy and further improve the user experience.

[0089] Preferably, the water dispenser of the present invention further includes an alarm device (not shown in the figure), and the specific steps of "selectively activating the sterilization mode according to the comparison results" include:

[0090] If L < L1, the alarm device will sound an alarm to remind the user to add water to water tank 1.

[0091] It should be noted that, in practical applications, those skilled in the art can configure the alarm device as a sound alarm module, or as a light alarm module, or even as a combined sound and light alarm module, etc. Such adjustments and changes to the specific configuration type of the alarm device do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0092] Preferably, after activating the sterilization mode, the control method of the present invention further includes:

[0093] Obtain the water temperature t in the circulating water circuit;

[0094] The sterilization mode is selectively terminated based on the water temperature t.

[0095] This setup ensures that the water temperature in the circulating water system is high enough to sterilize it, while also preventing the sterilization process from being too long and affecting normal use.

[0096] It should be noted that, in practical applications, those skilled in the art can obtain the water temperature in the circulating water circuit by measuring the water temperature in the water tank 1, or by measuring the water temperature in the heating chamber 21, or by measuring the water temperature in the first connecting pipe 31 and the second connecting pipe 32, etc. Such adjustments and changes to the specific method of obtaining the water temperature in the circulating water circuit do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0097] Preferably, such as Figure 1As shown, a first water outlet pipe 41 connected to the bottom of the water tank 1 is provided. A second temperature detection component 13 is provided near the water tank 1 on the first water outlet pipe 41. When the water dispenser is in sterilization mode, the first water outlet valve 411 is closed, that is, the water in the water tank 1 will flow into the first water outlet pipe 41. The water temperature in the water tank 1 can be obtained by detecting the water temperature in the first water outlet pipe 41 through the second temperature detection component 13.

[0098] It should be noted that in practical applications, the second temperature detection component 13 is not limited to being placed inside the first water outlet pipe 41. For example, the second temperature detection component 13 can be placed directly inside the water tank 1, and the water temperature inside the water tank 1 can be directly measured through the second temperature detection component 13, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0099] Preferably, the specific steps of "selectively ending the sterilization mode according to the water temperature t" include:

[0100] Compare the water temperature t with the preset water temperature t0;

[0101] If t≥t0, then the sterilization mode ends;

[0102] If t < t0, the sterilization mode will not end.

[0103] With this setting, when the water temperature t exceeds the preset water temperature t0, it means that the water temperature during sterilization is high enough to sterilize the circulating water circuit at high temperature. At this time, the sterilization mode is ended, which can save energy and avoid the sterilization time being too long and affecting the normal use of the user. When the water temperature t has not yet reached t0, it means that the water temperature in the circulating water circuit is too low to sterilize the circulating water circuit at high temperature. At this time, the sterilization mode is not ended.

[0104] It should be noted that in practical applications, the comparison is not limited to directly comparing the water temperature t with the preset water temperature t0 as described above. For example, the difference between the water temperature t and the preset water temperature t0 can be calculated first, and then compared with the preset value. Alternatively, the ratio of the water temperature t to the preset water temperature t0 can be calculated first, and then compared with the preset value, etc. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should all be included within the protection scope of this invention. Of course, it is preferable to directly compare the water temperature t with the preset water temperature t0.

[0105] like Figure 1 As shown, the water dispenser of the present invention also includes a water storage tank 5, which is connected to the water tank 1 via a water inlet pipe 6. A self-priming pump 61 is provided on the water inlet pipe 6. When the water tank 1 is short of water, the self-priming pump 61 can draw water from the water storage tank 5 into the water tank 1.

[0106] Preferably, the control method of the present invention further includes:

[0107] When the water level L in water tank 1 is detected to be lower than the third preset water level L3, the self-priming pump 61 starts to work.

[0108] When the water level L in water tank 1 is detected to reach the third preset water level L3, the self-priming pump 61 stops working.

[0109] With this setup, when the water level in water tank 1 is lower than the set height, it indicates that the water volume in water tank 1 is insufficient. By starting the self-priming pump 61 and allowing water from the storage tank 5 to enter water tank 1, the water tank 1 will have enough water for the user. When water is being added to water tank 1, when the water level in water tank 1 reaches the set height, it indicates that the water in water tank 1 has reached its maximum capacity. At this point, stopping the self-priming pump 61 can prevent water from overflowing if water continues to be added.

[0110] It should be noted that in practical applications, the comparison is not limited to the water level L in water tank 1 being compared with the third preset water level L3. For example, a first liquid level switch can also be installed in water tank 1. When water is used in water tank 1, that is, when the water level in water tank 1 is lower than the normally open contact of the first liquid level switch, the normally open contact of the first liquid level switch is in the open state, which causes the self-priming pump 61 to start working and allow water to enter water tank 1. When the water level in water tank 1 is higher than the normally open contact of the first liquid level switch, the normally open contact of the first liquid level switch is closed, which causes the self-priming pump 61 to stop working, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0111] like Figure 1 As shown, an antibacterial component 14 is provided at the bottom of the water tank 1, which can inhibit the growth of bacteria in the water tank 1.

[0112] Preferably, the control method of the present invention further includes:

[0113] Compare the water level L with the second preset water level L2;

[0114] If L≥L2, then the antibacterial component 14 is activated.

[0115] With this setting, if the water level L in water tank 1 reaches the second preset water level L2, it means that water has started to enter water tank 1. At this time, the antibacterial component 14 is activated to inhibit bacteria in the water in water tank 1, thereby reducing the growth of bacteria in water tank 1 and keeping water tank 1 clean during use, further improving the user experience.

[0116] It should be noted that in practical applications, it is not limited to comparing the water level L with the second preset water level L2. For example, a second liquid level switch can also be set at the bottom of the water tank 1. When the water level in the water tank 1 is higher than the normally closed contact of the second liquid level switch, the normally closed contact of the second liquid level switch is opened. At this time, the antibacterial component 14 is activated, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be included within the protection scope of the present invention.

[0117] It should also be noted that in practical applications, a first liquid level switch can be set above the water tank 1, and a second liquid level switch can be set below the water tank 1. Alternatively, only one liquid level switch can be set inside the water tank 1. The liquid level switch includes a high liquid level contact and a low liquid level contact. The high liquid level contact is used to detect whether the water level in the water tank 1 has reached a third preset water level, and the low liquid level contact is used to detect whether the water level in the water tank 1 has reached a second preset water level, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0118] Preferably, such as Figure 1 As shown, a liquid level switch 12 is installed in the water tank 1. The liquid level switch 12 is equipped with a high liquid level contact and a low liquid level contact (not shown in the figure).

[0119] It should also be noted that, in practical applications, those skilled in the art can set the antibacterial component 14 as an LED antibacterial lamp bead, or as an ultraviolet lamp tube, or as other possible forms, etc. Such adjustments and changes to the specific configuration of the antibacterial component 14 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0120] Preferably, the antibacterial component 14 is configured as multiple LED ultraviolet antibacterial lamp beads (not shown in the figure), and the lamp beads are provided with lamp covers to prevent the lamp beads from contacting the water in the water tank 1.

[0121] It should be noted that, in practical applications, those skilled in the art can set the antibacterial component 14 to run continuously after startup, that is, the LED antibacterial lamp beads work continuously to inhibit bacteria in the water tank 1. Alternatively, the antibacterial component 14 can be set to run intermittently, that is, it stops working after working for a period of time and then continues to work after a period of time, etc. Such adjustments and changes to the specific working mode of the antibacterial component 14 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0122] For example, after the antibacterial component 14 is started, it works for 1 hour and then stops working. After stopping working for 2 hours, it resumes working, and so on. The antibacterial component 14 operates intermittently.

[0123] This configuration avoids the antibacterial component 14 from being constantly in operation, thus preventing energy waste. At the same time, it extends the service life of the antibacterial component 14 and further enhances the user experience.

[0124] Preferably, after the antibacterial component 14 is activated, the control method of the present invention further includes:

[0125] Determine if water has entered water tank 1;

[0126] If the judgment result is "yes", then the antibacterial component 14 will be activated.

[0127] With this setup, when water enters the water tank 1, the antibacterial component 14 is activated, which can promptly inhibit bacteria in the water tank 1, preventing bacteria from entering the water tank 1 with the newly entered water and surviving and multiplying in the water tank 1, thus further enhancing the antibacterial effect of the antibacterial component 14.

[0128] It should be noted that, in practical applications, those skilled in the art can determine whether water tank 1 has been replenished based on the number of times the water dispenser is used. That is, after water is used, the water in water tank 1 decreases, and water from the storage tank 5 will automatically replenish water tank 1. Alternatively, water tank 1 can be replenished based on whether the water level in water tank 1 rises. That is, the water level in water tank 1 is obtained at set intervals, and if the current water level is higher than the previous water level obtained, it is determined that water has entered water tank 1, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0129] Preferably, the water level in the water tank 1 is obtained by the water level detection component 11 in the water tank 1, and whether water has entered the water tank 1 is determined by whether the water level in the water tank 1 has risen.

[0130] For example, when the antibacterial component 14 has been working for 1 hour and is in the process of stopping, if water is detected entering the water tank 1, the antibacterial component 14 will be activated and will stop working after working for 1 hour. It will then resume working after stopping for 2 hours.

[0131] It should be noted that if the antibacterial component 14 is working when water is entering the water tank 1, the antibacterial component 14 will not be stopped, and will continue to work for 1 hour before stopping.

[0132] It should also be noted that the water dispenser of the present invention also includes a controller, which is configured to execute the control methods described above.

[0133] Preferably, the controller is communicatively connected to the water level detection component 11, the liquid level switch 12, the first temperature detection component 13, and the second temperature detection component 211, so as to transmit the acquired water temperature and the water level in the water tank 1 to the controller, thereby realizing intelligent data acquisition and transmission. The controller is also configured to communicate with the heating component 2, the rapid heating component 421, the first control valve 312, the second control valve 422, the water pump 311, and the self-priming pump 61. At the same time, the controller is also communicatively connected to the first water outlet valve 411 and the second water outlet valve 423, so as to realize intelligent control of water inlet, sterilization, and water outlet of the water dispenser, thereby improving the user experience.

[0134] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
