Description

Technical Field

[0001] The present invention relates to the technical field of heating, and more particularly, to a control method for a heating device, a heating device, and a readable storage medium. Background Art

[0002] Currently, electric heating water cups have been widely used by people. To ensure no water leakage during carrying, the cup lid needs to have good sealing performance. However, when heating with the lid closed, steam pressure will be generated inside the cup body, posing a safety hazard. Therefore, users need to open the lid to boil water. Such a design, on the one hand, provides a poor user experience; on the other hand, there is a safety risk in case the user forgets to open the lid to boil water.

[0003] In related technologies, a waterproof and breathable component and a pressure relief component are designed on the cup lid to ensure the balance of internal and external air pressures during heating with the lid closed, enabling boiling water with the lid closed. However, in this method, when the breathability of the waterproof and breathable component is fixed, if the heating power of the heating device is relatively large, the waterproof and breathable component can only discharge part of the steam per unit time, resulting in a continuous increase in the pressure inside the cup body, posing a safety risk. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] For this reason, one aspect of the present invention is to propose a control method for a heating device.

[0006] Another aspect of the present invention is to propose a heating device.

[0007] Still another aspect of the present invention is to propose a readable storage medium.

[0008] In view of this, according to one aspect of the present invention, a control method for a heating device is proposed. The heating device includes a main body, a lid, and a heating device. The lid is provided with a waterproof and breathable device. The main body is used for storing liquid, and the heating device is used for heating the main body. The water vapor generated inside the main body is discharged through the waterproof and breathable device. The control method includes: obtaining a target heating temperature and the temperature of the liquid inside the main body; based on the target heating temperature being greater than or equal to a first temperature, controlling the heating power of the heating device according to the liquid temperature and the breathability parameter of the waterproof and breathable device.

[0009] The heating device provided by the present invention includes a main body, a lid, and a heating device. The main body and the lid can be buckled together. The main body is used for storing liquid, and the heating device is used for heating the main body. The lid is provided with a waterproof and breathable device. When heated to a certain extent, part of the liquid inside the main body will be converted into water vapor, and the water vapor is discharged to the external environment through the waterproof and breathable device, enabling the heating device to boil water with the lid closed.

[0010] During the heating process, to avoid the problem of excessive pressure inside the body caused by poor steam discharge effect, the embodiment of the present invention proposes to control the heating power of the heating device according to the target heating temperature, the liquid temperature inside the body, and the air permeability performance parameters of the waterproof and breathable device. Specifically, when the target heating temperature is greater than or equal to the first temperature, it indicates that the user needs to heat the liquid to a relatively high temperature. Then, it is possible that the speed of liquid conversion into steam is too fast and the volume of steam is large. If the waterproof and breathable device can only discharge a small part of the steam per unit time, it will cause the pressure inside the body to continuously increase with the increase of heating time. On the one hand, there is a safety risk, and on the other hand, it will also make it difficult for the user to open the lid. Since the air permeability performance parameters of a certain waterproof and breathable device are usually fixed after being installed in the heating device, in the embodiment of the present invention, by combining the air permeability performance parameters of the waterproof and breathable device, the heating power of the heating device is controlled to make the speed or volume of steam generation adapt to the speed or volume of steam discharge, thereby keeping the pressure inside and outside the heating device body balanced, and avoiding the above problem of excessive pressure inside the body, and improving the use safety of the heating device.

[0011] It should be noted that the waterproof and breathable device is a waterproof and breathable membrane, and its air permeability performance parameter is the volume of steam passing through the waterproof and breathable membrane per unit time under a certain pressure (i.e., the pressure difference between the pressure on the side of the waterproof and breathable device facing the body and the pressure on the side facing the lid).

[0012] According to the control method of the above heating device of the present invention, the following additional technical features may also be provided:

[0013] In the above technical solution, the step of controlling the heating power of the heating device according to the liquid temperature and the air permeability performance parameters of the waterproof and breathable device specifically includes: based on the target heating temperature being the boiling point of heating, controlling the heating power of the heating device according to the liquid temperature, the boiling point of heating, and the air permeability performance parameters, where the boiling point of heating is higher than the first temperature.

[0014] In this technical solution, when the target heating temperature is the boiling point of heating, it indicates that the user needs to boil the liquid. At this time, the target heating temperature is greater than or equal to the first temperature. Further, according to the liquid temperature, the boiling point of heating, and the air permeability performance parameters, the heating power of the heating device is controlled to make the speed or volume of steam generation adapt to the speed or volume of steam discharge, and avoid excessive pressure inside the body.

[0015] In any of the above technical solutions, the step of controlling the heating power of the heating device according to the liquid temperature, the boiling point of heating, and the air permeability performance parameter specifically includes: based on the difference between the boiling point of heating and the liquid temperature being greater than or equal to the second temperature, controlling the heating device to operate in the full-power mode; based on the difference between the boiling point of heating and the liquid temperature being less than the second temperature, determining the target heating power according to the air permeability performance parameter, and controlling the heating device to operate in the power-adjusting mode according to the target heating power.

[0016] In this technical solution, a method of controlling the heating power of the heating device is defined. Specifically, calculate the difference between the boiling point of heating and the liquid temperature. When the difference is greater than or equal to the second temperature, control the heating device for full-power heating, that is, heat at the maximum heating power of the heating device; when the difference is greater than 0 and less than the second temperature, control the heating device for power-adjusting heating, and the specific heating power of the power-adjusting heating is determined according to the air permeability performance parameter of the waterproof and breathable device. Through the above method, when the air permeability performance parameter of the waterproof and breathable device is certain, by adjusting the heating power of the heating device, the speed or volume of the steam generated by the heating device is adapted to the speed or volume of the steam discharged, and the pressure balance inside and outside the heating device can be maintained when heating the liquid without opening the lid.

[0017] It should be noted that since the speed or volume of the steam generated increases when approaching the boiling point of heating, for the accuracy of control, it is necessary to control the heating power in advance, that is, control according to the difference between the boiling point of heating and the liquid temperature, and perform power-adjusting control when the liquid temperature is close to the boiling point of heating.

[0018] In any of the above technical solutions, the control method further includes: receiving a heating function setting signal; based on the heating function being the boiling water heating function, obtaining the altitude information of the heating device; and determining the boiling point of heating according to the altitude information.

[0019] In this technical solution, the user can set the heating function. When it is determined that the heating function set by the user is the boiling water heating function, that is, when the user needs to boil the liquid, it is necessary to control the heating power of the heating device in combination with the boiling point of heating and the air permeability performance parameter of the waterproof and breathable device. And the boiling point of heating is different in different altitude areas. Therefore, obtain the altitude information of the heating device to determine the corresponding boiling point of heating. Through the above method, the accurate boiling point of heating can be determined, making the control of the heating power of the heating device more accurate, and further maintaining the pressure balance inside and outside the heating device.

[0020] For the method of obtaining the altitude information of the heating device, the altitude can be directly obtained, or the geographical location information of the heating device can be obtained, and then the altitude is determined according to the geographical location information.

[0021] It should be noted that the user can also directly input a heating temperature setting signal, that is, directly input the value of the target heating temperature, and then determine whether the input value is the boiling point of heating.

[0022] In any of the above technical solutions, the control method further includes: when the altitude information is not obtained, controlling the heating power of the heating device according to the liquid temperature, the first temperature, and the air permeability parameter.

[0023] In this technical solution, if the altitude information of the heating device cannot be obtained, the boiling point of heating cannot be obtained. Then, as long as it is determined that the target heating temperature is greater than or equal to the first temperature, the heating power of the heating device is controlled according to the liquid temperature, the first temperature, and the air permeability parameter of the waterproof and breathable device.

[0024] Specifically, based on the liquid temperature being less than or equal to the first temperature, controlling the heating device to operate in the full-power mode; based on the liquid temperature being greater than the first temperature, determining the target heating power according to the air permeability parameter, and controlling the heating device to operate in the power-adjusting mode according to the target heating power.

[0025] In the above manner, it is ensured that the pressure inside and outside the heating device body remains balanced, thus avoiding the problem of excessive pressure inside the body.

[0026] In any of the above technical solutions, the step of controlling the heating power of the heating device according to the liquid temperature, the first temperature, and the air permeability parameter specifically includes: based on the target heating temperature being greater than or equal to the first temperature, controlling the heating power of the heating device according to the liquid temperature, the first temperature, and the air permeability parameter when the target heating temperature is greater than or equal to the first temperature and less than the boiling point of heating, where the boiling point of heating is higher than the first temperature.

[0027] In this technical solution, when the target heating temperature is greater than or equal to the first temperature and less than the boiling point of heating, it indicates that the user needs to heat the liquid to a higher temperature but not to the boiling point of heating. In this case, the heating power of the heating device is controlled according to the liquid temperature, the first temperature, and the air permeability parameter, so that the speed or volume of the generated steam is adapted to the speed or volume of the discharged steam, avoiding excessive pressure inside the body.

[0028] In any of the above technical solutions, the step of controlling the heating power of the heating device according to the liquid temperature, the first temperature, and the air permeability parameter specifically includes: based on the liquid temperature being less than or equal to the first temperature, controlling the heating device to operate in the full-power mode; based on the liquid temperature being greater than the first temperature, determining the target heating power according to the air permeability parameter, and controlling the heating device to operate in the power-adjusting mode according to the target heating power.

[0029] In this technical solution, a method for controlling the heating power of a heating device is defined. Specifically, the magnitude relationship between the liquid temperature and the first temperature is compared. When the liquid temperature is less than or equal to the first temperature, the heating device is controlled to heat at full power, that is, to heat at the maximum heating power of the heating device. When the liquid temperature is greater than the first temperature, the heating device is controlled to perform power-adjustable heating, and the heating power of the specific power-adjustable heating is determined according to the air permeability performance parameters of the waterproof and breathable device. Through the above method, when the air permeability performance parameters of the waterproof and breathable device are certain, by adjusting the heating power of the heating device, the speed or volume of the steam generated by the heating device is adapted to the speed or volume of the steam discharged, and the pressure balance inside and outside the heating device can be maintained when heating the liquid without opening the lid.

[0030] It should be noted that since the target heating temperature is lower than the boiling point of heating, the speed or volume of the steam generated during heating is relatively small compared to the case where the target heating temperature is the boiling point of heating. Therefore, the difference between the first temperature and the liquid temperature can be not used to control the heating power to improve the control speed.

[0031] In any of the above technical solutions, the step of determining the target heating power according to the air permeability performance parameters specifically includes: determining the target heating power according to the air permeability performance parameters and the heating efficiency of the heating device.

[0032] In this technical solution, based on the air permeability performance parameters, the heating efficiency of the heating device is increased, so that the target heating power is determined by combining the air permeability performance parameters and the heating efficiency, and the accuracy of the target heating power is improved.

[0033] In any of the above technical solutions, the heating power in the power-adjustable mode is greater than 0 and less than or equal to where A is the air permeability performance parameter, η is the heating efficiency of the heating device, B is the volume change coefficient, and C is the heat absorption coefficient.

[0034] In this technical solution, it is defined that the heating power p in the power-adjustable mode satisfies the following relational expression: 0 < (p×η×B) / C ≤ 3×A. Optionally, the heating power p satisfies 0.8×A < (p×η×B) / C ≤ 1.5×A.

[0035] Among them, A is the air permeability performance parameter (which can be the air permeability at 5 kPa pressure, with the unit of ml / s), which is an inherent characteristic of the waterproof and breathable device and can be set before the heating device leaves the factory. In the embodiment of the present invention, at 5 kPa pressure, the range of A is greater than or equal to 10 ml / s and less than or equal to 150 ml / s. By setting this range, the air permeability performance and waterproof performance (i.e., the water seepage pressure) of the waterproof and breathable device are balanced as much as possible, and the waterproof and breathable effect is improved.

[0036] η is the heating efficiency of the heating device, which is an inherent characteristic of the heating device and can be set before the heating equipment leaves the factory.

[0037] B is the volume change coefficient, that is, the volume increase of a certain weight of liquid converted into steam of the same weight, with a value of 1667. C is the heat absorption coefficient, that is, the heat absorbed by a certain temperature of liquid converted into steam at the same temperature, with a value of 2260.

[0038] Through the above limitations, the speed or volume of the steam generated by heating is adapted to the speed or volume of the steam discharged by the waterproof and breathable device, so as to keep the pressure inside and outside the heating equipment balanced.

[0039] According to another aspect of the present invention, a heating device is proposed, including: a body for storing liquid; a heating device for heating the body; a cover body provided with a waterproof and breathable device, and the water vapor generated inside the body is discharged through the waterproof and breathable device; a memory for storing programs or instructions; and a processor that implements the steps of the control method of the heating device in any of the above technical solutions when the processor executes the programs or instructions.

[0040] The heating device provided by the present invention includes a body, a cover body and a heating device. The body and the cover body can be buckled together. The body is used for storing liquid, the heating device is used for heating the body, and the cover body is provided with a waterproof and breathable device. When heated to a certain extent, part of the liquid inside the body will be converted into water vapor, and the water vapor is discharged to the external environment through the waterproof and breathable device, so that the heating device can boil water with the cover closed.

[0041] During the heating process, in order to avoid the problem of excessive pressure inside the body caused by poor discharge effect of water vapor, the embodiment of the present invention proposes to control the heating power of the heating device according to the target heating temperature, the liquid temperature inside the body and the air permeability performance parameters of the waterproof and breathable device. Specifically, when the target heating temperature is greater than or equal to the first temperature, it indicates that the user needs to heat the liquid to a higher temperature. Then, it is possible that the speed of the liquid being converted into water vapor is too fast and the volume of the water vapor is large. If the waterproof and breathable device can only discharge a small part of the water vapor per unit time, it will cause the pressure inside the body to continuously increase with the increase of the heating time. On the one hand, there is a safety risk, and on the other hand, it will also make it difficult for the user to open the cover. Since the air permeability performance parameters of a certain waterproof and breathable device are usually fixed after being installed in the heating equipment, in the embodiment of the present invention, in combination with the air permeability performance parameters of the waterproof and breathable device, the heating power of the heating device is controlled so that the speed or volume of the generated steam is adapted to the speed or volume of the discharged steam, thereby keeping the pressure inside and outside the heating equipment balanced, and thus avoiding the above problem of excessive pressure inside the body and improving the use safety of the heating device.

[0042] It should be noted that the waterproof and breathable device is a waterproof and breathable membrane, and its air permeability parameter is the volume of steam passing through the waterproof and breathable membrane per unit time under a certain pressure (i.e., the pressure difference between the pressure on the side of the waterproof and breathable device facing the main body and the pressure on the side of the waterproof and breathable device facing the cover).

[0043] According to the above heating device of the present invention, the following additional technical features may also be provided:

[0044] In the above technical solution, the water seepage pressure of the waterproof and breathable device is greater than or equal to 30 kPa and less than or equal to 80 kPa.

[0045] In this technical solution, the water seepage pressure of the waterproof and breathable device is negatively correlated with the air permeability, that is, the greater the water seepage pressure, the poorer the air permeability, and the smaller the water seepage pressure, the better the air permeability. On the one hand, the water seepage pressure of the waterproof and breathable device is limited to be greater than or equal to 30 kPa to avoid the phenomenon that the heating device is prone to water seepage due to a small water seepage pressure. For example, when the heating device is filled with hot water and even gently shaken, it will cause the pressure inside the heating device to be greater than the external environment, and due to the small water seepage pressure, the heating device is prone to water seepage. On the other hand, the water seepage pressure of the waterproof and breathable device is limited to be less than or equal to 80 kPa to avoid large water seepage pressure and difficult water seepage, thereby avoiding excessive pressure inside the main body of the heating device.

[0046] It should be noted that further, the water seepage pressure can be limited to be greater than or equal to 45 kPa and less than or equal to 60 kPa.

[0047] In any of the above technical solutions, under a pressure of 5 kPa, the air permeability parameter of the waterproof and breathable device is greater than or equal to 10 ml / s and less than or equal to 150 ml / s.

[0048] In this technical solution, the air permeability parameter is an inherent characteristic of the waterproof and breathable device and can be set before the heating device leaves the factory. In the embodiment of the present invention, under a pressure of 5 kPa (i.e., the pressure difference between the pressure on the side of the waterproof and breathable device facing the main body and the pressure on the side of the waterproof and breathable device facing the cover is 5 kPa), the range of the air permeability parameter is greater than or equal to 10 ml / s and less than or equal to 150 ml / s, and can be selected to be greater than or equal to 30 ml / s and less than or equal to 100 ml / s. By setting this range, the air permeability and waterproof performance (i.e., water seepage pressure) of the waterproof and breathable device can be achieved as much as possible, improving the waterproof and breathable effect.

[0049] According to another aspect of the present invention, a readable storage medium is proposed, on which a program or instruction is stored, and when the program or instruction is executed by a processor, the steps of the control method of the heating device in any of the above technical solutions are implemented.

[0050] The readable storage medium provided by the present invention, when the program or instruction is executed by a processor, realizes the steps of the control method of the heating device in any of the above technical solutions. Therefore, the readable storage medium includes all the beneficial effects of the control method of the heating device in any of the above technical solutions.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0063] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings).

Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0066] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0067] In an embodiment of the first aspect of the present invention, a control method for a heating device is proposed. The heating device includes a main body, a cover body, and a heating device. The cover body is provided with a waterproof and breathable device. The main body is used for storing liquid, and the heating device is used for heating the main body. The water vapor generated in the main body is discharged through the waterproof and breathable device. The control method for the heating device is described through the following Embodiment 1 to Embodiment 5.

[0068] Embodiment 1, Figure 1 shows one of the flow diagrams of the control method for the heating device according to the embodiment of the present invention. Among them, the control method includes:

[0069] Step 102, obtain the target heating temperature and the temperature of the liquid inside the body;

[0070] Step 104, based on the target heating temperature being greater than or equal to the first temperature, control the heating power of the heating device according to the liquid temperature and the air permeability performance parameter of the waterproof and breathable device.

[0071] The heating device provided by the present invention includes a body, a cover body, and a heating device. The body and the cover body can be buckled together. The body is used to store liquid, the heating device is used to heat the body, and a waterproof and breathable device is arranged on the cover body. When heated to a certain extent, part of the liquid inside the body will be converted into water vapor, and the water vapor is discharged to the external environment through the waterproof and breathable device, so that the heating device can boil water with the cover closed.

[0072] During the heating process, in order to avoid the problem that the pressure inside the body is too high due to the poor discharge effect of water vapor, the embodiment of the present invention proposes to control the heating power of the heating device according to the target heating temperature, the temperature of the liquid inside the body, and the air permeability performance parameter of the waterproof and breathable device. Specifically, when the target heating temperature is greater than or equal to the first temperature, it indicates that the user needs to heat the liquid to a relatively high temperature. Then, it is possible that the speed of the liquid being converted into water vapor is too fast and the volume of the water vapor is large. If the waterproof and breathable device can only discharge a small part of the water vapor per unit time, it will cause the pressure inside the body to continuously increase with the increase of the heating time. On the one hand, there is a safety risk, and on the other hand, it will also make it difficult for the user to open the cover. Since the air permeability performance parameter of a certain waterproof and breathable device is usually fixed after it is installed in the heating device, in the embodiment of the present invention, the heating power of the heating device is controlled in combination with the air permeability performance parameter of the waterproof and breathable device, so that the speed or volume of generating steam is adapted to the speed or volume of discharging steam, and further the pressure inside and outside the body of the heating device is kept balanced, thereby avoiding the above problem of excessive pressure inside the body and improving the use safety of the heating device.

[0073] It should be noted that the waterproof and breathable device is a waterproof and breathable membrane, and its air permeability performance parameter is the volume of steam passing through the waterproof and breathable membrane per unit time under a certain pressure (that is, the pressure difference between the pressure received by the waterproof and breathable device on the side facing the body and the pressure received by the waterproof and breathable device on the side facing the cover body).

[0074] The first temperature in the embodiment of the present invention is less than the boiling points corresponding to different altitudes in various regions of the country, and its range can be greater than or equal to 86 °C and less than or equal to 90 °C, for example, it is set to 86 °C.

[0075] Embodiment Two Figure 2 Fig. 2 shows the second flow chart of the control method of the heating device according to the embodiment of the present invention. Among them, the control method includes:

[0076] Step 202, obtain the target heating temperature and the temperature of the liquid inside the body;

[0077] Step 204, determine whether the target heating temperature is equal to the boiling point of heating. If it is equal to the boiling point of heating, go to step 206; otherwise, return to step 202;

[0078] Step 206, control the heating power of the heating device according to the liquid temperature, the boiling point of heating, and the air permeability parameter.

[0079] Among them, the boiling point of heating is higher than the first temperature.

[0080] In this technical solution, when the target heating temperature is the boiling point of heating, it indicates that the user needs to boil the liquid. At this time, the target heating temperature is greater than or equal to the first temperature. Further, according to the liquid temperature, the boiling point of heating, and the air permeability parameter, control the heating power of the heating device so that the speed or volume of the generated steam is adapted to the speed or volume of the discharged steam, and avoid excessive pressure inside the body.

[0081] In the above technical solution, in step 206, controlling the heating power of the heating device according to the liquid temperature, the boiling point of heating, and the air permeability parameter specifically includes: based on the difference between the boiling point of heating and the liquid temperature being greater than or equal to the second temperature, control the heating device to work in the full-power mode; based on the difference between the boiling point of heating and the liquid temperature being less than the second temperature, determine the target heating power according to the air permeability parameter, and control the heating device to work in the power-adjusting mode according to the target heating power.

[0082] In this technical solution, a way to control the heating power of the heating device is defined. Specifically, calculate the difference between the boiling point of heating and the liquid temperature. When this difference is greater than or equal to the second temperature, control the heating device for full-power heating, that is, heat at the maximum heating power of the heating device; when this difference is greater than 0 and less than the second temperature, control the heating device for power-adjusting heating, and the specific heating power of the power-adjusting heating is determined according to the air permeability parameter of the waterproof and breathable device. Through the above method, when the air permeability parameter of the waterproof and breathable device is constant, by adjusting the heating power of the heating device, the speed or volume of the steam generated by the heating device is adapted to the speed or volume of the discharged steam, and the pressure balance inside and outside the heating device can be maintained when heating the liquid without opening the lid.

[0083] It should be noted that since the speed or volume of the generated steam increases when approaching the boiling point of heating, therefore, for the accuracy of control, it is necessary to control the heating power in advance, that is, control according to the difference between the boiling point of heating and the liquid temperature, and perform power-adjusting control when the liquid temperature is close to the boiling point of heating.

[0084] Among them, 1°C ≤ the second temperature ≤ 8°C, and optionally 3°C ≤ the second temperature ≤ 6°C. By limiting the above range, the control of the heating power of the heating device is made more precise, improving the heating effect.

[0085] In the above technical solution, the heating device is controlled to operate in a power adjustment mode according to the target heating power, and the heating device is controlled to stop heating until the difference between the heating boiling point and the liquid temperature ≤ 0.5°C.

[0086] In the above technical solution, the step of determining the target heating power according to the air permeability parameter specifically includes: determining the target heating power according to the air permeability parameter and the heating efficiency of the heating device.

[0087] In this technical solution, based on the air permeability parameter, the heating efficiency of the heating device is increased, so that the target heating power is determined by combining the air permeability parameter and the heating efficiency, improving the accuracy of the target heating power.

[0088] In the above technical solution, the heating power in the power adjustment mode is greater than 0 and less than or equal to Among them, A is the air permeability parameter, η is the heating efficiency of the heating device, B is the volume change coefficient, and C is the heat absorption coefficient.

[0089] In this technical solution, it is limited that the heating power p in the power adjustment mode satisfies the following relational expression: 0 < (p×η×B) / C ≤ 3×A. Optionally, the heating power p satisfies 0.8×A < (p×η×B) / C ≤ 1.5×A.

[0090] Among them, A is the air permeability parameter (which can be the air permeability at 5 kPa pressure, with the unit of ml / s), which is an inherent characteristic of the waterproof and breathable device and can be set before the heating equipment leaves the factory. In the embodiment of the present invention, at 5 kPa pressure, the range of A is greater than or equal to 10 ml / s and less than or equal to 150 ml / s. By setting this range, the air permeability and waterproof performance (i.e., the water seepage pressure) of the waterproof and breathable device are made as balanced as possible, improving the waterproof and breathable effect.

[0091] η is the heating efficiency of the heating device, which is an inherent characteristic of the heating device and can be set before the heating equipment leaves the factory.

[0092] B is the volume change coefficient, that is, the volume increase amount when a certain weight of liquid is converted into steam of the same weight, and the value is 1667. C is the heat absorption coefficient, that is, the heat absorbed when a certain temperature of liquid is converted into steam at the same temperature, and the value is 2260. For example, converting 100°C water into 100°C water vapor requires absorbing 2260 joules of heat.

[0093] Through the above limitations, the speed or volume of the steam generated by heating is adapted to the speed or volume of the steam discharged by the waterproof and breathable device, thereby keeping the pressure inside and outside the heating device balanced.

[0094] Embodiment III Figure 3 Fig. 3 shows a third schematic flowchart of the control method of the heating device according to an embodiment of the present invention. Among them, the control method includes:

[0095] Step 302, receiving a heating function setting signal;

[0096] Step 304, based on the heating function being the boiling water heating function, obtaining the altitude information of the heating device, and determining that the target heating temperature is the boiling point;

[0097] Step 306, determining the value of the boiling point according to the altitude information;

[0098] Step 308, controlling the heating power of the heating device according to the liquid temperature, the value of the boiling point, and the air permeability parameter.

[0099] Among them, the boiling point is higher than the first temperature.

[0100] In this technical solution, the user can set the heating function. When it is determined that the heating function set by the user is the boiling water heating function, that is, when the user needs to boil the liquid, it is necessary to control the heating power of the heating device in combination with the boiling point and the air permeability parameter of the waterproof and breathable device. Since the boiling points in different altitude regions are different, the altitude information of the heating device is obtained to determine the corresponding boiling point. Through the above method, an accurate boiling point can be determined, making the control of the heating power of the heating device more accurate, thereby maintaining the pressure balance inside and outside the heating device.

[0101] For the method of obtaining the altitude information of the heating device, the altitude can be directly obtained, or the geographical location information of the heating device can be obtained, and then the altitude is determined according to the geographical location information.

[0102] In some embodiments, the altitude information can also be converted into geographical location information that is relatively close, so as to retrieve the boiling point of water corresponding to this geographical location.

[0103] The heating device is connected to the smart terminal through a Bluetooth module or a WiFi module, so as to obtain geographical location information or altitude information.

[0104] It should be noted that the user can also directly input a heating temperature setting signal, that is, directly input the value of the target heating temperature, and then determine whether the input value is the boiling point.

[0105] In the above technical solution, the control method further includes: when altitude information is not obtained, controlling the heating power of the heating device according to the liquid temperature, the first temperature, and the air permeability parameter.

[0106] In this technical solution, if the altitude information of the heating device cannot be obtained, the heating boiling point cannot be obtained. Then, as long as it is determined that the target heating temperature is greater than or equal to the first temperature, the heating power of the heating device is controlled according to the liquid temperature, the first temperature, and the air permeability parameter of the waterproof and breathable device.

[0107] Specifically, based on the liquid temperature being less than or equal to the first temperature, controlling the heating device to operate in the full-power mode; based on the liquid temperature being greater than the first temperature, determining the target heating power according to the air permeability parameter, and controlling the heating device to operate in the power adjustment mode according to the target heating power.

[0108] In the above manner, it is ensured that the pressure inside and outside the heating device remains balanced, thereby avoiding the problem of excessive pressure inside the device.

[0109] Embodiment 4 Figure 4 shows the fourth flow schematic diagram of the control method of the heating device according to the embodiment of the present invention. Among them, the control method includes:

[0110] Step 402, obtaining the target heating temperature and the liquid temperature inside the device;

[0111] Step 404, determining whether the target heating temperature is equal to the heating boiling point. If it is equal to the heating boiling point, go to step 406; otherwise, go to step 408;

[0112] Step 406, controlling the heating power of the heating device according to the liquid temperature, the heating boiling point, and the air permeability parameter;

[0113] Step 408, determining whether the target heating temperature is greater than or equal to the first temperature. If it is greater than or equal to the first temperature, go to step 410; otherwise, go to step 412;

[0114] Step 410, controlling the heating power of the heating device according to the liquid temperature, the first temperature, and the air permeability parameter;

[0115] Step 412, controlling the heating power of the heating device according to the liquid temperature and the target heating temperature.

[0116] Among them, the heating boiling point is higher than the first temperature.

[0117] In this technical solution, when the target heating temperature is greater than or equal to the first temperature and less than the boiling point of heating, it indicates that the user needs to heat the liquid to a relatively high temperature but not to the boiling point of heating. In this case, according to the liquid temperature, the first temperature, and the air permeability parameter, the heating power of the heating device is controlled so that the speed or volume of the generated steam is adapted to the speed or volume of the discharged steam, avoiding excessive pressure inside the body.

[0118] In any of the above technical solutions, in step 410, controlling the heating power of the heating device according to the liquid temperature, the first temperature, and the air permeability parameter specifically includes: based on the liquid temperature being less than or equal to the first temperature, controlling the heating device to operate in the full-power mode; based on the liquid temperature being greater than the first temperature, determining the target heating power according to the air permeability parameter, and controlling the heating device to operate in the power-adjusting mode according to the target heating power.

[0119] In this technical solution, a method of controlling the heating power of the heating device is defined. Specifically, the magnitude relationship between the liquid temperature and the first temperature is compared. In the case where the liquid temperature is less than or equal to the first temperature, the heating device is controlled for full-power heating, that is, heating is performed at the maximum heating power of the heating device; in the case where the liquid temperature is greater than the first temperature, the heating device is controlled for power-adjusting heating, and the heating power of the specific power-adjusting heating is determined according to the air permeability parameter of the waterproof and breathable device. By the above method, when the air permeability parameter of the waterproof and breathable device is constant, by adjusting the heating power of the heating device, the speed or volume of the steam generated by the heating device is adapted to the speed or volume of the discharged steam, and the pressure balance inside and outside the heating device can be maintained while realizing heating the liquid without opening the lid.

[0120] It should be noted that since the target heating temperature is less than the boiling point of heating, the speed or volume of the steam generated during heating is relatively small compared to the case where the target heating temperature is the boiling point of heating. Therefore, the difference between the first temperature and the liquid temperature can be not used for controlling the heating power to improve the control speed.

[0121] In the above technical solution, the heating device is controlled to operate in the power-adjusting mode according to the target heating power until the temperature change difference of the liquid temperature in the heating device is less than 0.5 °C within a time period of more than 30 s, and it is considered that the liquid in the heating device reaches boiling, then the heating is stopped.

[0122] In the above technical solution, the step of determining the target heating power according to the air permeability parameter specifically includes: determining the target heating power according to the air permeability parameter and the heating efficiency of the heating device.

[0123] In this technical solution, based on the air permeability performance parameter, the heating efficiency of the heating device is increased, so as to determine the target heating power by combining the air permeability performance parameter and the heating efficiency, and the accuracy of the target heating power is improved.

[0124] In any of the above technical solutions, the heating power of the power adjustment mode is greater than 0 and less than or equal to where A is the air permeability performance parameter, η is the heating efficiency of the heating device, B is the volume change coefficient, and C is the heat absorption coefficient.

[0125] In this technical solution, it is specified that the heating power p of the power adjustment mode satisfies the following relational expression: 0 < (p×η×B) / C ≤ 3×A. Optionally, the heating power p satisfies 0.8×A < (p×η×B) / C ≤ 1.5×A.

[0126] where A is the air permeability performance parameter (which can be the air permeability at a pressure of 5 kPa, with the unit of ml / s). It is an inherent characteristic of the waterproof and breathable device and can be set before the heating device leaves the factory. In the embodiments of the present invention, at a pressure of 5 kPa, the range of A is greater than or equal to 10 ml / s and less than or equal to 150 ml / s. By setting this range, the air permeability performance and waterproof performance (i.e., the water seepage pressure) of the waterproof and breathable device are balanced as much as possible, and the waterproof and breathable effect is improved.

[0127] η is the heating efficiency of the heating device, which is an inherent characteristic of the heating device and can be set before the heating device leaves the factory.

[0128] B is the volume change coefficient, that is, the volume increase when a certain weight of liquid is converted into steam of this weight, and its value is 1667. C is the heat absorption coefficient, that is, the heat absorbed when a certain temperature of liquid is converted into steam at this temperature, and its value is 2260. For example, converting 100°C water into 100°C water vapor requires absorbing 2260 joules of heat.

[0129] Through the above specification, the speed or volume of the steam generated by heating is adapted to the speed or volume of the steam discharged by the waterproof and breathable device, so as to keep the pressure inside and outside the heating device body balanced.

[0130] In the above technical solution, based on the target heating temperature being less than the first temperature, according to the liquid temperature and the target heating temperature, the heating power of the heating device is controlled. Specifically, in step 412, controlling the heating power of the heating device according to the liquid temperature and the target heating temperature includes: based on the difference between the target heating temperature and the liquid temperature being greater than or equal to the third temperature, controlling the heating device to operate in the full power mode; based on the difference between the target heating temperature and the liquid temperature being less than the third temperature, controlling the heating device to operate in the power adjustment mode.

[0131] In this technical solution, when the target heating temperature is less than the first temperature, the difference between the target heating temperature and the liquid temperature is calculated, and the heating power is controlled according to the difference, so as to realize heating the liquid without opening the lid and improve the heating safety.

[0132] Among them, 1°C ≤ the third temperature ≤ 6°C, and it can be selected as 2°C ≤ the third temperature ≤ 4°C. By limiting the above range, the control of the heating power of the heating device is made more accurate, and the heating effect is improved.

[0133] In the above technical solution, the heating device is controlled to work in the power adjustment mode until the difference between the target heating temperature and the liquid temperature ≤ 0.5°C, and then the heating device is controlled to stop heating.

[0134] Embodiment 5, the heating device is an electric kettle Figure 5 The flowchart of the control method of the electric kettle according to the embodiment of the present invention is shown. Among them, the control method includes:

[0135] Step 502, when the electric kettle is in the on state, receive the boiling function selected by the user;

[0136] Step 504, determine whether the boiling function selected by the user is the boiling water function. If so, go to step 506; if not, go to step 516;

[0137] Step 506, determine whether geographical location information or altitude information is obtained. If so, go to step 508; if not, go to step 512;

[0138] Step 508, according to the geographical location information or altitude information, determine different boiling programs Px through calculation;

[0139] Step 510, heat according to the determined boiling program Px;

[0140] Step 512, heat according to the set boiling program P2;

[0141] Step 516, determine whether the boiling temperature T1 selected by the user is greater than 86°C. If so, go to step 512; if not, go to step 518;

[0142] Step 518, heat according to the set boiling program P1.

[0143] Among them, according to the altitude information (the altitude is denoted as h), the boiling point T0 of water at this location or area can be calculated (where T0 = 100 - h / 328). The boiling water program Px is as follows: (1) Detect the water temperature T in the electric kettle. When T0 - T ≥ ΔT1, control the heating power to be full power heating, where 1°C ≤ ΔT1 ≤ 8°C. For example, select 3°C ≤ ΔT1 ≤ 6°C; (2) When 0 < T0 - T < ΔT1, control the heating power to be power-adjusted heating until T0 - T ≤ 0.5°C, then stop heating. At this time, the heating power p satisfies the following relational expression: 0 < p×η×1667 / 2260 ≤ 3A. For example, select 0.8×A ≤ p×η×1667 / 2260 ≤ 1.5×A. Among them, the unit of the heating power p is W, η is the heating efficiency of the electric kettle, which is an inherent characteristic of the electric kettle and can be entered into the program before leaving the factory. A is the air permeability parameter of the waterproof and breathable device (i.e., the air permeability at 5 kPa pressure, with the unit of ml / s), which is determined during the design of the electric kettle and can be entered into the program before leaving the factory.

[0144] The boiling water program P2 includes: Detect the water temperature T in the electric kettle. When T ≤ 86°C, control the heating power to be full power heating; when T > 86°C, control the heating power to be power-adjusted heating, and the heating power is p until the temperature change difference of the water temperature T within more than 30 s is less than 0.5°C, then it is considered that the water in the kettle has reached boiling and stop heating. At this time, the heating power p satisfies the following relational expression: 0 < p×η×1667 / 2260 ≤ 3A. For example, select 0.8×A ≤ p×η×1667 / 2260 ≤ 1.5×A. Among them, the unit of the heating power p is W, η is the heating efficiency of the electric kettle, which is an inherent characteristic of the electric kettle and can be entered into the program before leaving the factory. A is the air permeability parameter of the waterproof and breathable device (i.e., the air permeability at 5 kPa pressure, with the unit of ml / s), which is determined during the design of the electric kettle and can be entered into the program before leaving the factory.

[0145] The boiling water program P1 includes: (1) Detect the water temperature T in the electric kettle. The selected boiling water temperature by the user is T1. When T1 - T ≥ ΔT2, control the heating power to be full power heating, where 1°C ≤ ΔT2 ≤ 6°C. For example, select 2°C ≤ ΔT2 ≤ 4°C; (2) When 0 < T1 - T < ΔT2, control the heating power to be power-adjusted heating until T1 - T ≤ 0.5°C, then stop heating.

[0146] In this embodiment, aiming at the problems existing in the existing electric kettle with the lid closed for boiling water, through optimizing the program, the heating power is associated with the air permeability of the waterproof and breathable device, thus better solving the problems in the prior art. The specific scheme is as follows:

[0147] (1) Determine whether the boiling function selected by the user is the boiling water function. If not, then determine whether the selected boiling water temperature is greater than 86°C. If it is not greater than 86°C, then heat according to the set boiling water program P1 to complete boiling water; if it is greater than 86°C, then heat according to the set boiling water program P2 to complete boiling water.

[0148] (2) If the boiling water function selected by the user is the boiling water function, determine whether geographical location or altitude information is obtained. If obtained, uniformly convert the geographical location or altitude information into altitude information, and then determine different boiling water programs Px through calculation based on the input altitude information, and heat according to the determined boiling water program Px to complete boiling water.

[0149] (3) If the boiling water function selected by the user is the boiling water function, but geographical location or altitude information cannot be obtained, then heat according to the boiling water program P2 to complete boiling water.

[0150] For example, in a specific embodiment, the user selects the 55°C gear to boil water. According to the judgment, select the boiling water program P1 to complete the boiling water operation.

[0151] In another specific embodiment, the user selects the boiling water gear to boil water. The cup body of the electric boiling water cup obtains an altitude of 1500 meters through Bluetooth signal. By calculating, the boiling point of water in this area is 95.4°C, △T1 is 5°C, and when the water temperature is lower than 90.4°C, full power heating is performed. When it is detected that the water temperature is higher than 90.4°C, power adjustment heating starts. Since the heating efficiency η of this electric boiling water cup is 85%, and the air permeability parameter A of the waterproof and breathable device on the lid of the electric boiling water cup at 5 kPa is 60 ml / s, through calculation, the range of the heating power p for power adjustment heating is 76.6W ≤ p ≤ 143.5W, and heating can be stopped when the water temperature exceeds 95°C.

[0152] In another specific embodiment, the user selects the boiling water gear to boil water. The electric boiling water cup cannot obtain geographical location or altitude information. When the water temperature in the electric boiling water cup is higher than 86°C, power adjustment heating starts. Since the heating efficiency η of this electric boiling water cup is 90%, and the air permeability A of the waterproof and breathable device on the lid of the electric boiling water cup at 5 kPa is 80 ml / s, through calculation, the range of the power p for power adjustment heating is 96.4W ≤ p ≤ 180.8W. When it is detected that the water temperature does not change by more than 0.5°C within more than 30 s, it is considered that the water temperature has reached the boiling point and heating can be stopped.

[0153] An embodiment of the second aspect of the present invention proposes a heating device, which is a portable heating device, such as Figure 6 and Figure 7 shown. This heating device includes:

[0154] A body 62 for storing liquid;

[0155] A heating device for heating the body 62;

[0156] A cover 64 is provided with a waterproof and breathable device 6404, and the water vapor generated in the body 62 is discharged through the waterproof and breathable device 6404;

[0157] A memory for storing programs or instructions;

[0158] A processor, when the processor executes the program or instructions, realizes the steps of the control method of the heating device according to any one of the above technical solutions.

[0159] Wherein, the memory and the processor can be connected by a bus or other means. The processor may include one or more processing units, and the processor may be a central processing unit (CPU), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc.

[0160] The heating device provided by the present invention includes a body 62, a cover 64 and a heating device. The body 62 and the cover 64 can be buckled together. The body 62 is used for storing liquid, the heating device is used for heating the body 62, and the cover 64 is provided with a waterproof and breathable device 6404. When heated to a certain extent, part of the liquid in the body 62 will be converted into water vapor, and the water vapor is discharged to the external environment through the waterproof and breathable device 6404, so that the heating device realizes boiling water with the cover closed.

[0161] During the heating process, to avoid the problem of excessive pressure inside the main body 62 caused by poor steam discharge effect, the embodiment of the present invention proposes to control the heating power of the heating device according to the target heating temperature, the liquid temperature inside the main body 62, and the air permeability performance parameters of the waterproof and breathable device 6404. Specifically, when the target heating temperature is greater than or equal to the first temperature, it indicates that the user needs to heat the liquid to a relatively high temperature. Then, it is possible that the speed of liquid conversion into steam is too fast and the volume of steam is large. If the waterproof and breathable device 6404 can only discharge a small part of the steam per unit time, it will cause the pressure inside the main body 62 to continuously increase with the increase of heating time. On the one hand, there is a safety risk, and on the other hand, it will also make it difficult for the user to open the lid. Since the air permeability performance parameters of a certain waterproof and breathable device 6404 are usually fixed after it is installed in the heating device, in the embodiment of the present invention, in combination with the air permeability performance parameters of the waterproof and breathable device 6404, the heating power of the heating device is controlled to make the speed or volume of steam generation adapt to the speed or volume of steam discharge, thereby keeping the pressure inside and outside the heating device main body 62 balanced, and thus avoiding the above problem of excessive pressure inside the main body 62 and improving the use safety of the heating device.

[0162] It should be noted that the waterproof and breathable device 6404 is a waterproof and breathable membrane, and its air permeability performance parameter is the volume of steam passing through the waterproof and breathable membrane per unit time under a certain pressure (i.e., the pressure difference between the pressure on the side of the waterproof and breathable device 6404 facing the main body 62 and the pressure on the side of the waterproof and breathable device 6404 facing the lid 64).

[0163] In some embodiments, the lid 64 further includes:

[0164] A first lid main body 6408, on which a first exhaust hole 64022 is provided;

[0165] A second lid main body 6410, on which a second exhaust hole 64024 is provided. The second exhaust hole 64024 and the first exhaust hole 64022 form an exhaust device, and the steam passes through the first exhaust hole 64022, the waterproof and breathable device 6404, and the second exhaust hole 64024 in sequence and is discharged to the external environment;

[0166] The air pressure balance component 6406 is hermetically connected to the first cover body 6408. The waterproof and breathable device 6404 is arranged between the air pressure balance component 6406 and the first cover body 6408. The air pressure balance component 6406 is used to keep the pressure inside and outside the main body 62 balanced when the waterproof and breathable device 6404 fails (impermeable or poor breathability). Specifically, an exhaust part 64062 is arranged on the air pressure balance component 6406. If the waterproof and breathable device 6404 fails, the pressure inside the main body 62 will increase. When the pressure is greater than a certain value, the steam will push open the exhaust part 64062 and then be discharged.

[0167] The first thread structure 6412. When the first thread structure 6412 is threadedly connected to the second thread structure 6202 arranged on the main body 62, the cover body 64 and the main body 62 are buckled together.

[0168] The first seal 6414 is arranged on the first cover body 6408. When the cover body 64 and the main body 62 are buckled together, the first seal 6414 plays a sealing role to prevent air leakage or water leakage due to gaps between the cover body 64 and the main body 62.

[0169] The second seal 6416 is arranged between the air pressure balance component 6406 and the first cover body 6408, playing a sealing role.

[0170] The fixing part 6418 is connected to the air pressure balance component 6406 and the first cover body 6408, and is used to fix the air pressure balance component 6406 and the first cover body 6408 together.

[0171] In some embodiments, the heating device further includes:

[0172] A base 66, and the above-mentioned heating device is arranged inside the base 66.

[0173] In the above technical solution, the water seepage pressure of the waterproof and breathable device is greater than or equal to 30 kPa and less than or equal to 80 kPa.

[0174] In this technical solution, the water seepage pressure of the waterproof and breathable device is negatively correlated with the breathability performance, that is, the greater the water seepage pressure, the poorer the breathability, and the smaller the water seepage pressure, the better the breathability. On the one hand, the water seepage pressure of the waterproof and breathable device is limited to be greater than or equal to 30 kPa to avoid the phenomenon that the heating device is prone to water seepage due to a small water seepage pressure. For example, when the heating device is filled with hot water and even gently shaken, the pressure generated by the heating device will be greater than the external environment pressure, and due to the small water seepage pressure, the heating device is prone to water seepage. On the other hand, the water seepage pressure of the waterproof and breathable device is limited to be less than or equal to 80 kPa to avoid difficult water seepage due to a large water seepage pressure, thereby avoiding excessive pressure inside the main body of the heating device.

[0175] It should be noted that, further, the seepage pressure can be defined as being greater than or equal to 45 kPa and less than or equal to 60 kPa.

[0176] In any of the above technical solutions, at a pressure of 5 kPa, the air permeability performance parameter of the waterproof and breathable device is greater than or equal to 10 ml / s and less than or equal to 150 ml / s.

[0177] In this technical solution, the air permeability performance parameter is an inherent characteristic of the waterproof and breathable device and can be set before the heating device leaves the factory. In the embodiments of the present invention, at a pressure of 5 kPa (that is, the pressure difference between the pressure received by the waterproof and breathable device on the side facing the body and the pressure received by the waterproof and breathable device on the side facing the cover is 5 kPa), the range of the air permeability performance parameter is greater than or equal to 10 ml / s and less than or equal to 150 ml / s, and can be optionally greater than or equal to 30 ml / s and less than or equal to 100 ml / s. By setting this range, the air permeability performance and waterproof performance (i.e., seepage pressure) of the waterproof and breathable device can be obtained as much as possible, improving the waterproof and breathable effect.

[0178] An embodiment of the third aspect of the present invention provides a readable storage medium, on which a program or instruction is stored, and when the program or instruction is executed by a processor, the steps of the control method of the heating device in any of the above technical solutions are implemented.

[0179] Among them, the computer-readable storage medium includes a read-only memory (ROM), a random access memory (RAM), a magnetic disk, an optical disk, etc.

[0180] The readable storage medium provided by the present invention, when the program or instruction is executed by a processor, implements the steps of the control method of the heating device in any of the above technical solutions, so this readable storage medium includes all the beneficial effects of the control method of the heating device in any of the above technical solutions.

[0181] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
