[0039] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0040] Figure 1 The flowchart of the method for liquid heating equipment in one embodiment of the present invention is schematically shown. Figure 1 As shown, in an embodiment of the present invention, a method for a liquid heating device is provided, and the method is described by taking the method applied to a processor as an example. The method may include the following steps:

[0041] Step S110, determining the liquid temperature rising rate of the liquid heating device during the heating process.

[0042] It can be understood that the liquid heating device is a device for heating liquid, such as a water dispenser, an instant hot water dispenser, an electric kettle and the like. The liquid temperature rise rate is the amount of change in the temperature rise of the liquid within a unit time or unit period, such as 20 degrees Celsius per second. The liquid temperature rise rate will gradually decrease as the temperature rises. For example, if the time period is 0.4 seconds, the liquid temperature rise rate of the liquid heating device before 80 degrees Celsius is 20 degrees Celsius per 0.4 seconds, and it starts to slow down to 15 degrees Celsius per 0.4 seconds above 80 degrees Celsius, and slows down to 10 degrees Celsius per 0.4 seconds above 90 degrees Celsius. The slowing law of the liquid temperature rise rate at different altitudes is different. The higher the altitude, the earlier the liquid temperature rise rate slows down. For example, at a higher altitude, the temperature rise rate of 70 degrees Celsius begins to slow down.

[0043] Specifically, during the heating process of the liquid heating device, the processor can obtain the temperature information detected by the temperature sensor, and determine the temperature rise change of the liquid within a unit time or unit period, that is, the liquid temperature rise rate, according to the temperature information and the corresponding time information. The time information corresponding to the temperature can be determined by the processor (for example, a single chip microcomputer).

[0044] Step S120, determining the altitude information of the liquid heating device according to the pre-stored mapping relationship between altitude and temperature rise rate and the liquid temperature rise rate.

[0045] It can be understood that the mapping relationship is a mapping relationship between altitudes of different gears and the corresponding temperature rise rate of the altitude region. The mapping relationship can be stored in the form of a table and pre-stored in the liquid heating device shipped from the factory. For example, an altitude of 8,000 meters can be divided into different numbers of altitude gears. The more gears there are, the more accurate the mapping relationship is, so as to meet the boiling point accuracy requirements of liquid heating equipment at different altitude levels.

[0046] Specifically, the processor pre-stores a mapping relationship between altitude and temperature rise rate, and searches for altitude information corresponding to the liquid temperature rise rate in the mapping relationship according to the liquid temperature rise rate, thereby determining the altitude information of the liquid heating device.

[0047] In an example, the mapping relationship may include the relationship between altitude, temperature rise rate, temperature and time. Furthermore, the temperature rise rate, temperature and time may be stored in the form of a sequence array or in the form of a surface graph.

[0048] Step S130, determining the boiling point of the liquid heating device according to the altitude information.

[0049] Specifically, the processor may determine the boiling point of the liquid heating device based on the relationship between the altitude information and the boiling point.

[0050] In one embodiment, the above step S130 may include: determining the boiling point of the liquid heating device according to a preset algorithm and altitude information.

[0051] It can be understood that the relationship between atmospheric pressure and altitude satisfies:

[0052]

[0053] Where p is the atmospheric pressure in kPa, and h is the local altitude in km.

[0054] Therefore, the relationship between boiling point and altitude can satisfy:

[0055]

[0056] Among them, t 沸腾 is the local boiling point of water (i.e. boiling temperature), and h is the local altitude.

[0057] The above formula (2) is the preset algorithm in this embodiment, that is, an algorithm including the mapping relationship between boiling point and altitude. The processor can determine the boiling point of the altitude area where the liquid heating device is located by determining the altitude information and the above formula (2).

[0058] In this embodiment, the processor can determine the boiling point of the liquid heating device according to the pre-stored preset algorithm and altitude information, thereby improving the accuracy of boiling point determination.

[0059] Step S140, determining the maximum outlet water temperature of the liquid heating device according to the boiling point.

[0060] It can be understood that the maximum water outlet temperature is the maximum heating temperature at which the liquid heating equipment is set without generating steam spraying phenomenon in the corresponding altitude area.

[0061] Specifically, after determining the boiling point of the region where the liquid heating device is located, the processor can set the maximum water outlet temperature of the liquid heating device according to the boiling point.

[0062] In one embodiment, determining the maximum water outlet temperature of the liquid heating device according to the boiling point includes: subtracting a preset margin protection value from the boiling point to obtain the maximum water outlet temperature of the liquid heating device.

[0063] Specifically, the following formula (3) may be referred to:

[0064] t max = 沸腾 -Δt Formula (3)

[0065] Among them, Δt is the preset margin protection value, t 沸腾 is the boiling point of water at that location, t max The maximum outlet water temperature.

[0066] The value of the preset margin protection value Δt can be determined according to the temperature stability performance of the liquid heating device, for example, it can be a value in the range of [3,5]. Furthermore, in the temperature adjustment process of the liquid heating device, a dynamic adjustment algorithm such as a PID control algorithm usually has a certain overshoot, so a certain protection margin needs to be reserved to avoid the phenomenon of steam spraying caused by the excessive water temperature of the liquid heating device.

[0067] The above method for liquid heating equipment determines the rate of increase of the temperature of the liquid in the liquid heating equipment during the heating process, determines the altitude information of the liquid heating equipment according to the pre-stored mapping relationship between altitude and temperature rise rate and the rate of increase of the liquid temperature, thereby determining the boiling point of the liquid heating equipment according to the altitude information, and determining the maximum water outlet temperature of the liquid heating equipment according to the boiling point. The above method does not need to obtain altitude information through the network, that is, it does not need to connect the equipment to the network. By comparing the rate of increase of the temperature of the liquid in the liquid heating equipment during the heating process with the pre-stored mapping relationship, the altitude information of the area where the liquid heating equipment is located can be determined, thereby determining the boiling point according to the altitude information, and setting the maximum water outlet temperature. This can reduce the incidence of steam spray accidents in liquid heating equipment that is not connected to the network, extend the service life of the equipment, and increase the safety of users.

[0068] In one embodiment, the mapping relationship further includes a mapping relationship between altitude and liquid boiling point; determining the boiling point of the liquid heating device according to the altitude information includes: determining the boiling point of the liquid heating device according to the altitude information based on the mapping relationship.

[0069] It can be understood that the mapping relationship between altitude and temperature rise rate can also include the relationship between altitude and corresponding liquid boiling point, which can be pre-stored in the liquid heating device, for example, the mapping relationship is pre-configured before the device leaves the factory.

[0070] Specifically, after determining the altitude information, the processor may search for a mapping relationship between the altitude and the boiling point according to the altitude information, thereby determining the boiling point of the liquid heating device.

[0071] In this embodiment, the boiling point information corresponding to the altitude information is searched based on the pre-stored mapping relationship, which can reduce the calculation workload of the liquid heating device.

[0072] Figure 2 The flowchart of the method for liquid heating equipment in one embodiment of the present invention is schematically shown. Figure 2 As shown, in an embodiment of the present invention, a method for a liquid heating device is provided, and the method is described by taking the application of the method to a server as an example. The method may include the following steps:

[0073] Step S210, determining the altitude information of the networked liquid heating equipment and the rate of increase of the liquid temperature during the heating process.

[0074] It can be understood that a network-connected liquid heating device refers to a liquid heating device that has completed network configuration through the Internet or mobile phone interconnection, for example, IOT network configuration is performed when the liquid heating device is powered on for the first time.

[0075] Specifically, the networked liquid heating equipment can obtain the altitude information of the area through the network, and send the altitude information and the temperature information detected by the temperature sensor during the heating process to the server. The server calculates the liquid temperature rise rate of the liquid heating equipment corresponding to the altitude information based on the temperature information and the corresponding time information.

[0076] In one example, the liquid temperature rise rate can be calculated by a processor of the liquid heating device based on temperature information and corresponding time information, and then sent to a server for storage.

[0077] Step S220, determining the corresponding liquid boiling point according to the altitude information.

[0078] In one example, the server can determine the boiling point of the liquid heating device according to a preset algorithm and altitude information. It can be understood that the relationship between atmospheric pressure and altitude satisfies:

[0079]

[0080] Where p is the atmospheric pressure in kPa, and h is the local altitude in km.

[0081] Therefore, the relationship between boiling point and altitude can satisfy:

[0082]

[0083] Among them, t沸腾 is the local boiling point of water (i.e. boiling temperature), and h is the local altitude.

[0084] The above formula (2) is a preset algorithm, that is, an algorithm including a mapping relationship between boiling point and altitude. The server can determine the boiling point of the altitude area where the liquid heating device is located by determining the altitude information and the above formula (2).

[0085] In one example, the server may determine the boiling point of the liquid heating device according to the altitude information based on the mapping relationship.

[0086] It can be understood that the mapping relationship includes the relationship between the altitude and the corresponding liquid boiling point, which can be pre-stored on the server.

[0087] Specifically, after determining the altitude information, the server can search for a mapping relationship between the altitude and the boiling point according to the altitude information, thereby determining the boiling point of the liquid heating device.

[0088] Step S230, determining a mapping relationship according to the liquid temperature rising rate, the altitude information and the liquid boiling point.

[0089] Specifically, after determining the liquid temperature rise rate, altitude information, and liquid boiling point, the server can generate a mapping relationship between the three, which can be in the form of a table. For example, an altitude of 8,000 meters can be divided into different numbers of altitude levels. The more levels there are, the more accurate the mapping relationship is, so as to meet the boiling point accuracy requirements of liquid heating equipment at different altitude levels.

[0090] The above method for liquid heating equipment determines the altitude information of the networked liquid heating equipment and the rate of increase of the liquid temperature during the heating process, determines the corresponding liquid boiling point according to the altitude information, and determines the mapping relationship according to the rate of increase of the liquid temperature, the altitude information, and the liquid boiling point. In the above method, the altitude can be divided into different gears, and the mapping relationship between the altitude and the temperature performance of different altitude gears can be determined, so that it can be pre-stored before the equipment leaves the factory. Subsequently, the mapping relationship can be searched by the temperature rise rate to determine the corresponding altitude information and boiling point information without the need for networking, thereby reducing the incidence of steam spray accidents in liquid heating equipment that is not networked, extending the service life of the equipment, and increasing the safety of user use.

[0091] Figure 3 The structure block diagram of a device for liquid heating equipment in one embodiment of the present invention is schematically shown. Figure 3 As shown, in an embodiment of the present invention, a device 300 for a liquid heating device is provided, comprising: a temperature sensor 310 and a processor 320, wherein:

[0092] The temperature sensor 310 is used to detect the temperature of the liquid during the heating process of the liquid heating device.

[0093] Processor 320 is configured to: obtain the liquid temperature of the liquid heating device during the heating process; determine the liquid temperature rising rate based on the liquid temperature; determine the altitude information of the liquid heating device based on the pre-stored mapping relationship between altitude and temperature rising rate and the liquid temperature rising rate; determine the boiling point of the liquid heating device based on the altitude information; and determine the maximum water outlet temperature of the liquid heating device based on the boiling point.

[0094] It can be understood that the liquid heating device is a device for heating liquid, such as a water dispenser, an instant hot water dispenser, an electric kettle and the like. The liquid temperature rise rate is the amount of change in the temperature rise of the liquid within a unit time or unit period, such as 20 degrees Celsius per second. The liquid temperature rise rate will gradually decrease as the temperature rises. For example, if the time period is 0.4 seconds, the liquid temperature rise rate of the liquid heating device before 80 degrees Celsius is 20 degrees Celsius per 0.4 seconds, and it starts to slow down to 15 degrees Celsius per 0.4 seconds above 80 degrees Celsius, and slows down to 10 degrees Celsius per 0.4 seconds above 90 degrees Celsius. The slowing law of the liquid temperature rise rate at different altitudes is different. The higher the altitude, the earlier the liquid temperature rise rate slows down. For example, at a higher altitude, the temperature rise rate of 70 degrees Celsius begins to slow down.

[0095] The mapping relationship is a mapping relationship between altitudes of different gears and the corresponding temperature rise rate of the altitudes. The mapping relationship can be stored in the form of a table and pre-stored in the liquid heating equipment shipped from the factory. For example, an altitude of 8,000 meters can be divided into different numbers of altitude gears. The more gears there are, the more accurate the mapping relationship is, so as to meet the boiling point accuracy requirements of liquid heating equipment at different altitude levels. The maximum water outlet temperature is the highest heating temperature at which the liquid heating equipment is set to not produce steam spraying in the corresponding altitude area.

[0096] Specifically, during the heating process of the liquid heating device, the processor 320 can obtain the temperature information detected by the temperature sensor 310, and determine the temperature rise change of the liquid within a unit time or unit period, that is, the liquid temperature rise rate, according to the temperature information and the corresponding time information. The time information corresponding to the temperature can be determined by the processor 320 (for example, a single chip microcomputer).

[0097] The processor 320 pre-stores a mapping relationship between altitude and temperature rise rate, and searches for altitude information corresponding to the liquid temperature rise rate in the mapping relationship according to the liquid temperature rise rate, thereby determining the altitude information of the liquid heating device. The processor 320 can determine the boiling point of the liquid heating device according to the relationship between the altitude information and the boiling point. After determining the boiling point of the area where the liquid heating device is located, the processor 320 can set the maximum water outlet temperature of the liquid heating device according to the boiling point.

[0098] The above method for liquid heating equipment determines the rate of increase of the temperature of the liquid in the liquid heating equipment during the heating process, determines the altitude information of the liquid heating equipment according to the pre-stored mapping relationship between altitude and temperature rise rate and the rate of increase of the liquid temperature, thereby determining the boiling point of the liquid heating equipment according to the altitude information, and determining the maximum water outlet temperature of the liquid heating equipment according to the boiling point. The above method does not need to obtain altitude information through the network, that is, it does not need to connect the equipment to the network. By comparing the rate of increase of the temperature of the liquid in the liquid heating equipment during the heating process with the pre-stored mapping relationship, the altitude information of the area where the liquid heating equipment is located can be determined, thereby determining the boiling point according to the altitude information, and setting the maximum water outlet temperature. This can reduce the incidence of steam spray accidents in liquid heating equipment that is not connected to the network, extend the service life of the equipment, and increase the safety of users.

[0099] In one embodiment, the mapping relationship further includes a mapping relationship between altitude and liquid boiling point; the processor 320 is further configured to: determine the boiling point of the liquid heating device according to the altitude information based on the mapping relationship.

[0100] It can be understood that the mapping relationship between altitude and temperature rise rate can also include the relationship between altitude and corresponding liquid boiling point, which can be pre-stored in the liquid heating device, for example, the mapping relationship is pre-configured before the device leaves the factory.

[0101] Specifically, after determining the altitude information, the processor 320 may search for a mapping relationship between the altitude and the boiling point according to the altitude information, thereby determining the boiling point of the liquid heating device.

[0102] In this embodiment, the boiling point information corresponding to the altitude information is searched based on the pre-stored mapping relationship, which can reduce the calculation workload of the liquid heating device.

[0103] In one embodiment, the processor 320 is further configured to determine the boiling point of the liquid heating device according to a preset algorithm and the altitude information.

[0104] It can be understood that the relationship between atmospheric pressure and altitude satisfies:

[0105]

[0106] Where p is the atmospheric pressure in kPa, and h is the local altitude in km.

[0107] Therefore, the relationship between boiling point and altitude can satisfy:

[0108]

[0109] Among them, t 沸腾 is the local boiling point of water (i.e. boiling temperature), and h is the local altitude.

[0110] The above formula (2) is the preset algorithm in this embodiment, that is, an algorithm including the mapping relationship between boiling point and altitude. The processor 320 can determine the boiling point of the altitude area where the liquid heating device is located by determining the altitude information and the above formula (2).

[0111] In this embodiment, the processor can determine the boiling point of the liquid heating device according to the pre-stored preset algorithm and altitude information, thereby improving the accuracy of boiling point determination.

[0112] In one embodiment, the processor 320 is further configured to: subtract a preset margin protection value from the boiling point to obtain the maximum water outlet temperature of the liquid heating device.

[0113] Specifically, the following formula (3) may be referred to:

[0114] t max =t 沸腾 -Δt Formula (3)

[0115] Among them, Δt is the preset margin protection value, t 沸腾 is the boiling point of water at that location, t max The maximum outlet water temperature.

[0116] The value of the preset margin protection value Δt can be determined according to the temperature stability performance of the liquid heating device, for example, it can be a value in the range of [3,5]. Furthermore, in the temperature adjustment process of the liquid heating device, a dynamic adjustment algorithm such as a PID control algorithm usually has a certain overshoot, so a certain protection margin needs to be reserved to avoid the phenomenon of steam spraying caused by the excessive water temperature of the liquid heating device.
