Description

Technical Field

[0001] The present invention relates to the technical field of electric water heating equipment, and in particular to an electric water heating equipment and a water quality detection method, device and computer-readable storage medium thereof. Background Art

[0002] In some specific scenarios, such as making tea, users need to use boiling water for a long time and in large quantities.

[0003] However, when water is repeatedly boiled, a series of potential health problems and water quality changes may occur:

[0004] 1. Accumulation of harmful substances: After some water evaporates, the concentration of harmful substances such as nitrite will increase. Nitrite can be converted into nitrosamine in the body. Nitrosamine is a potential carcinogen. Long-term intake may have adverse effects on health. Heavy metals in water (such as lead, mercury, etc.) may also gradually accumulate during repeated heating, further increasing health risks.

[0005] 2. Water becomes hard: Mineral concentration increases: During repeated boiling, the concentration of minerals such as calcium and magnesium in the water increases, making the water harder. Hard water not only affects the taste of the water, but also causes scale formation, affecting the service life of the kettle and pipes.

[0006] 3. Reduced dissolved oxygen: Changes in the taste of water: Repeated heating will gradually reduce the dissolved oxygen in the water, which may cause the water to taste bland and affect the user's drinking experience.

[0007] In the above scenarios, or due to some bad water-boiling habits of users, "repeatedly boiled water" will be produced. "Repeatedly boiled water" refers to water that has been repeatedly heated in an electric kettle or a kettle. Due to repeated heating, some volatile substances in the water will gradually decrease, while some non-volatile substances, such as heavy metals and nitrites, may gradually accumulate, thus causing potential health effects. In addition, during the repeated heating of water, the dissolved oxygen will gradually decrease, and the taste of the water may become bland.

[0008] If a pot of water is boiled multiple times (more than 3 times) in one day, or is kept in a boiling state for more than 15 minutes, it can be considered "thousands of boiling water". "Thousands of boiling water" not only poses potential health risks to users, but users cannot enjoy high-quality drinking water for a long time, which greatly affects the user experience.

[0009] Therefore, the prior art needs to be further developed. Summary of the invention

[0010] The purpose of the present invention is to overcome the above-mentioned technical deficiencies and provide an electric water heating device and a water quality detection method, device and computer-readable storage medium thereof to solve the technical problem in the related art that the electric water heating device is prone to produce "thousand-boiled water" during use.

[0025] Further, according to the consecutive number of times that the drinking water reaches the second state or the third state, the user is reminded to determine whether the electric water heating device continues to heat the drinking water, including:

[0027] When the number of consecutive times that the recorded drinking water is in the second state or the third state reaches a second number threshold, a third reminder message is issued, and the electric water heating device stops heating the drinking water.

[0028] Furthermore, the water quality detection method also includes:

[0029] When the drinking water is converted from the second state or the third state to the first state, the consecutive times are reset.

[0065] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0066] Example 1

[0067] According to an embodiment of the present invention, a method for detecting water quality of an electric water heating device is provided. Figures 1 to 6 ,include:

[0068] Monitor water intake from electrical water heating equipment after the drinking water is boiled for the first time;

[0069] Obtaining weight information of drinking water stored in an electric water heating device;

[0070] Continuously perform boiling detection on drinking water to obtain boiling detection information of drinking water;

[0071] According to the water intake situation and weight information of the electric water heating device and the boiling detection information of the drinking water, the state of the drinking water in the electric water heating device is determined;

[0072] According to the state of the drinking water, the user is reminded to determine whether the electric water heating device continues to heat the drinking water.

[0073] In some embodiments, when the electric water heating device is an electric kettle, the electric water heating device includes a base and a water storage container for storing and heating drinking water, namely, a kettle.

[0074] Specifically, the electric water heating device includes a weighing sensor and a temperature sensor. The electric water heating device includes a water storage container for heating and storing drinking water. The water storage container can be a kettle in an electric kettle or the like. The weighing sensor is located below the water storage container and is used to weigh the water storage container and the drinking water stored therein, thereby obtaining the weight information of the drinking water stored in the electric water heating device. The temperature sensor is used to detect the water temperature of the drinking water and determine whether the drinking water is boiling according to the water temperature of the drinking water, thereby obtaining the boiling detection information of the drinking water. In this embodiment, the weighing sensor is used to detect the water volume, and the temperature sensor is used to detect the water temperature. The two cooperate with each other to determine the user's habit of boiling water and taking water, and remind the user of bad habits.

[0075] Through the above method, by obtaining the weight information and boiling detection information of the electric water heating device, the state of drinking water is defined, and when the quality of drinking water is detected to be poor, a reminder is issued to the user to remind the user of the drinking water quality to ensure the user's drinking water health. When necessary, the electric water heating device is controlled to stop heating. In addition, by defining the state of drinking water, the user's water boiling habits can be judged to improve the user's water boiling habits and solve the technical problem in the related technology that the electric water heating device is prone to produce "thousands of boiling water" during use.

[0076] In the water quality detection method of the electric water heating device of this embodiment, the water intake condition includes the water intake condition and the water non-intake condition. According to the water intake condition and weight information of the electric water heating device and the boiling detection information of the drinking water, the state of the drinking water in the electric water heating device is judged, including:

[0077] When the user takes water, if the weight information after taking water does not exceed the first preset water level, the electric water heating device replenishes water and heats the drinking water until the drinking water boils again, and the current state of the drinking water is determined to be the first state;

[0078] When the user takes water, if the weight information after taking water exceeds the first preset water level, it is detected whether the user adds water;

[0079] When it is detected that the user adds water, the drinking water is heated until the drinking water boils again, and the current state of the drinking water is determined to be the second state;

[0080] When it is detected that the user has not added water, the drinking water is heated until the drinking water boils again, and it is determined that the current state of the drinking water is the third state.

[0081] In some embodiments, if the user takes water and puts the water storage container back to the base, the weighing sensor detects that the weight information of the remaining water in the water storage container does not exceed the first preset water level. At this time, the amount of drinking water in the water storage container is too little, and the drinking water is automatically added to the default capacity, or added to the user-set value and heated to boil. At this time, the drinking water is defined as the first state. For example, when the amount of drinking water is detected to be less than 200ml, the weight information of the remaining water does not exceed the first preset water level, and the drinking water is automatically added to 800ml. In the first state, the remaining water amount of drinking water is small and water is replenished.

[0082] In some embodiments, if the weight information after taking water exceeds the first preset water level, it is determined whether the user manually adds water. For example, when it is detected that the remaining water volume in the water storage container is ≥200ml, the weight information exceeds the first preset water level.

[0083] When it is detected that the user manually adds water and boils it again, the boiled water is defined as the second state. Because there is too much water left in the kettle from the first boil (maybe 200ml-500ml), there are also more residual minerals (such as calcium, magnesium) and nitrites. When water is added and boiled for the second time, the concentration of minerals and nitrites will increase. In the second state, the remaining amount of drinking water is moderate and water is replenished.

[0084] When it is detected that the user has not manually added water, in this case the user may have taken less water, and the remaining amount of drinking water may be relatively large, possibly 500ml-800ml. Since the user took the water from the water storage container and did not heat it in time, the temperature of the drinking water dropped. The temperature sensor detected that the temperature of the drinking water was below 95°C. The user chose to reheat and boil the water. At this time, the re-boiled water is defined as the third state. In the third state, the remaining amount of drinking water is relatively large and no water is added.

[0085] It can be understood that the water quality in the first state can be considered as healthy water quality, while the second and third states are considered as poor water quality.

[0086] Specifically, by collecting weight information after water extraction and the water added by the user, the water replenishment and boiling action at different water levels is detected, and the drinking water status is defined accordingly, thereby achieving accurate classification of the drinking water quality and reminding users to pay attention to drinking water health according to the drinking water status.

[0087] It should be noted that in the electric water heating equipment of the prior art, the water replenishment process does not only exist in the case of automatic water replenishment at low water level. Users will perform additional water replenishment operations based on various factors. However, the existing electric water heating equipment cannot distinguish between the above-mentioned various water replenishment actions, cannot accurately prevent the generation of thousands of boiling water, and cannot judge the user's boiling water habits through the above-mentioned water replenishment actions.

[0088] Through the above-mentioned water quality detection method, water is replenished and re-boiled at different water levels, and different definitions are made for the water states after re-boiling at different water levels. If there is too much water and the water is replenished and boiled, it is defined as "thousand-boiled water"; if the water is moderate and the water is replenished and boiled, it is also defined as "thousand-boiled water" (a more accurate definition should be "yin and yang water"). In the general user's cognition, drinking too much of these two types of water is not good for human health. Based on this, this application makes a test and reminds the user of the health problem of drinking water. Therefore, this application makes a test for this water replenishment and boiling operation and uses it to remind the user. Through the above-mentioned water replenishment action, the user's water boiling and water collection habits can be accurately judged, so as to pay attention to the user's drinking water health and improve the user experience.

[0089] In the water quality detection method of the electric water heating device of this embodiment, according to the state of the drinking water, the user is reminded to determine whether the electric water heating device continues to heat the drinking water, including:

[0090] When the drinking water is in the second state or the third state, the number of consecutive times the drinking water reaches the second state or the third state is recorded;

[0091] According to the consecutive times that the drinking water reaches the second state or the third state, the user is reminded to determine whether the electric water heating device continues to heat the drinking water.

[0092] Specifically, the water quality of drinking water can be evaluated by counting the number of consecutive times that the drinking water reaches the second state or the third state. In addition, the user's water boiling habits can be judged by the number of consecutive times that the drinking water reaches the second state or the third state, and the water boiling habits can be fed back to the user in a timely manner, thereby facilitating the user to correct and improve the water boiling habits, thereby improving the user's water boiling habits.

[0093] In the water quality detection method of the electric water heating device of this embodiment, according to the consecutive number of times that the drinking water reaches the second state or the third state, the user is reminded to determine whether the electric water heating device continues to heat the drinking water, including:

[0094] When the number of consecutive times that the recorded drinking water is in the second state or the third state reaches the first number threshold, a second reminder message is issued, and the electric water heating device continues to heat the drinking water;

[0095] When the number of consecutive times that the recorded drinking water is in the second state or the third state reaches a second number threshold, a third reminder message is issued, and the electric water heating device stops heating the drinking water.

[0096] In some embodiments, when water is added to the kettle, or the same kettle of water is boiled repeatedly, for example, if the drinking water state is detected to be the second state or the third state for 3-5 consecutive times, the user is reminded that the drinking water quality is poor and new water needs to be replaced and boiled again for drinking.

[0097] In some embodiments, if the drinking water is detected to be in the second state or the third state for more than five consecutive times, heating needs to be stopped to prevent the user from continuing to heat the drinking water and causing the water quality to become worse, posing a health risk.

[0098] In the water quality detection method of the electric water heating equipment of this embodiment, the water quality detection method also includes:

[0099] When the drinking water is converted from the second state or the third state to the first state, the consecutive times are reset.

[0100] In some embodiments, after the drinking water is determined to be in the second state or the third state, when the user takes a large amount of drinking water so that the drinking water is converted to the first state, the consecutive times are reset to zero.

[0101] In the water quality detection method of the electric water heating device of this embodiment, according to the state of the drinking water, the user is reminded to determine whether the electric water heating device continues to heat the drinking water, including:

[0102] When the drinking water is in the first state, a first reminder message is issued, and the electric water heating device continues to heat the drinking water.

[0103] Specifically, when the drinking water is in the first state, it indicates that the quality of the drinking water is good and the user can continue to drink it.

[0104] In the water quality detection method of the electric water heating device of this embodiment, the electric water heating device includes a weighing sensor and a temperature sensor. The weighing sensor is used to detect the weight of the water storage container in the electric water heating device. Monitoring the water intake of the electric water heating device includes:

[0105] Get the current weight measured by the weighing sensor and the working status of the temperature sensor;

[0106] If the current weight meets the first preset condition and the working state of the temperature sensor meets the second preset condition, it is determined that the user takes water;

[0107] If the first preset condition and the second preset condition cannot be satisfied at the same time, it is determined that the user has not taken water.

[0108] In some embodiments, if the current weight measured by the weighing sensor is less than the weight of the empty kettle, the current weight satisfies the first preset condition, which means that the water storage container has been picked up and the weighing sensor on the base cannot detect the weight information.

[0109] In some embodiments, the temperature sensor is generally placed on the base and connected to the control board located in the water storage container through the base coupling plug. When the water storage container is picked up, the temperature sensor is disconnected from the control board and cannot detect the water temperature. The water temperature can only be detected when the water storage container is placed on the base. When the water storage container is picked up, the temperature sensor is in an open circuit state.

[0110] In some embodiments, when the working state of the temperature sensor is an open circuit state, the working state of the temperature sensor satisfies the second preset condition, indicating that the water storage container is picked up to take water.

[0111] It is understandable that the temperature sensor itself has the risk of open circuit, and the weighing sensor may also make mistakes, so the accuracy of judging whether water is taken from a single aspect is not high, and the combined judgment of the two is more accurate. Through the cooperation of the weighing sensor and the temperature sensor, it is possible to accurately detect whether the electric water heating equipment is being taken.

[0112] In the water quality detection method of the electric water heating device of this embodiment, the water intake condition includes the water intake condition and the water non-intake condition. According to the water intake condition and weight information of the electric water heating device and the boiling detection information of the drinking water, the state of the drinking water in the electric water heating device is judged, including:

[0113] When the user does not take water, the drinking water is heated until the drinking water reaches boiling again;

[0114] Get boiling duration;

[0115] When the boiling duration is greater than a preset time, it is determined that the drinking water is in a long-term boiling state, a fourth reminder message is issued, and the electric water heating device continues to heat the drinking water.

[0116] Specifically, if the user does not take water, the water in the kettle remains boiling for a long time. When the boiling time lasts longer than the preset time, the amount of oxygen dissolved in the water decreases and the taste may change. When the user takes water, a reminder is issued to inform the user that the water quality is poor and new water needs to be replaced. For example, if the temperature sensor detects that the boiling time exceeds 15 minutes and the boiling time lasts longer than the preset time, it is determined that the drinking water is in a long-term boiling state.

[0117] In the water quality detection method of the electric water heating equipment of this embodiment, the water quality detection method also includes:

[0118] When the electric water heating device is powered on, the weight information of the drinking water is obtained;

[0119] If the weight information meets the third preset condition, a water-staleness reminder message is issued;

[0120] If the weight information does not meet the third preset condition, the electric water heating device is used to replenish water, and the electric water heating device heats the drinking water until the drinking water boils for the first time.

[0121] When the electric water heating device is powered on, if the amount of stale water is large enough to make the weight information meet the third preset condition, it is determined that there is stale water (water that has not been used for a long time) in the kettle, and the user is reminded to replace new water; if not, water is automatically added to the default water addition amount, or the water addition amount set by the user and heated. For example, the weighing sensor detects whether the current weight of the water storage container is greater than the weight of the empty kettle. If the current weight is greater than the weight of the empty kettle, the weight information meets the third preset condition, indicating that there is stale water in the water storage container, and a stale water reminder message is issued.

[0122] Example 2

[0123] In the computer-readable storage medium of this embodiment, a water quality detection program for an electric water heating device is stored thereon, and when the water quality detection program for the electric water heating device is executed by the processor, the water quality detection method for the electric water heating device described above is implemented.

[0124] According to the computer-readable storage medium of the embodiment of the present invention, the water quality detection program of the electric water heating device is executed by the processor, and the state of the drinking water is defined by obtaining the weight information and boiling detection information of the electric water heating device. When the quality of the drinking water is detected to be poor, a reminder is issued to the user to remind the user of the drinking water quality to ensure the user's drinking water health. When necessary, the electric water heating device is controlled to stop heating. In addition, by defining the state of drinking water, the user's water boiling habits can be judged to improve the user's water boiling habits and solve the technical problem in the related technology that the electric water heating device is prone to produce "thousands of boiling water" during use.

[0125] Example 3

[0126] In the water quality detection device 100 of the electric water heating equipment of this embodiment, see Figure 2 , the water quality detection device 100 comprises:

[0127] The monitoring module 10 is used to monitor the water intake of the electric water heating device 1000;

[0128] An acquisition module 20, used to obtain the weight information of drinking water and the boiling detection information of drinking water stored in the electric water heating device 1000;

[0129] The judging module 30 is used to judge the state of the drinking water in the electric water heating device 1000 according to the water intake condition and weight information of the electric water heating device 1000 and the boiling detection information of the drinking water;

[0130] The control module 40 is used to remind the user according to the state of the drinking water and determine whether the electric water heating device 1000 continues to heat the drinking water.

[0131] It can be understood that the acquisition module 20 includes an electric water heating device including a weighing sensor and a temperature sensor, which are used to weigh the water storage container and the drinking water stored inside, so as to obtain the weight information of the drinking water stored in the electric water heating device. The temperature sensor is used to detect the water temperature of the drinking water, and determine whether the drinking water is boiling based on the water temperature of the drinking water, so as to obtain boiling detection information of the drinking water.

[0132] Example 4

[0133] In the electric water heating device 1000 of this embodiment, see Figure 3 The electric water heating device includes the water quality detection device 100 of the electric water heating device mentioned above.

[0134] In the electric water heating device 1000 of the present embodiment, the electric water heating device includes the water quality detection device 100 of the above-mentioned electric water heating device 1000. The state of drinking water is defined by obtaining the weight information and boiling detection information of the electric water heating device 1000. When the quality of drinking water is detected to be poor, a reminder is issued to the user to remind the user of the drinking water quality to ensure the user's drinking water health. When necessary, the electric water heating device 1000 is controlled to stop heating. In addition, by defining the state of drinking water, the user's water boiling habits can be judged to improve the user's water boiling habits and solve the technical problem in the related technology that the electric water heating device is prone to produce "thousands of boiling water" during use.

[0135] In some embodiments, the electric water heating device 1000 is an electric kettle.

[0136] Example 5

[0137] On the basis of any one of the implementations in Examples 1-4, a feasible specific implementation is further proposed when the electric kettle is used as the electric water heating device.

[0138] See also Figure 1-Figure 6 ,The electric kettle has a weighing sensor and a temperature sensor and a corresponding detection and processing module.

[0139] The temperature sensor is usually placed at the bottom of the kettle and connected to the control board through the base coupling plug. When the kettle is picked up, the temperature sensor is disconnected from the electric kettle control board and cannot detect the water temperature. The water temperature can only be detected when placed on the base.

[0140] See also Figure 4 , Figure 4 This is a flow chart of the stale water detection steps. When the user turns on the electric kettle and starts using it, the weighing sensor detects whether the current weight is greater than the weight of an empty kettle. If so, it is determined that there is stale water (water that has not been used for a long time) in the kettle. The weight information meets the third preset condition, and a stale water reminder message is issued to remind the user to replace new water. If there is no stale water, water is automatically added to the default water volume of 800 ml, or the water volume set by the user and heated.

[0141] After the water boils, the weighing sensor detects that the current weight is less than the weight of the empty kettle, that is, the current weight meets the first preset condition, and the temperature sensor cannot detect the water temperature. The control board detects that the temperature sensor is in an open circuit state, and the working state of the temperature sensor meets the second preset condition, and it is judged that the user picks up the kettle to get water.

[0142] See also Figure 5 , Figure 5This is a flow chart of the long-term boiling detection steps. If the user does not take water, the water in the kettle keeps boiling for a long time. The temperature sensor detects that the boiling duration exceeds the preset time 15 minutes, and the drinking water is determined to be in a long-term boiling state. Due to the long boiling duration, the amount of dissolved oxygen in the water decreases and the taste may change. A reminder is issued when the user takes water, and the fourth reminder message is issued to inform the user that the water quality is poor and new water needs to be replaced.

[0143] If the user takes water and puts the kettle back to the base, the weighing sensor detects the remaining water in the kettle. If the water in the kettle is less than 200 ml and the weight information does not exceed the first preset water level, it is judged that the water in the kettle is too little, and the kettle automatically adds water to the default capacity of 800 ml or the user-set value. It is heated and boiled, and the water in the kettle is defined as the first state.

[0144] If the amount of water in the pot is ≥200 ml, and the weight information exceeds the first preset water level, the next step of detection is entered to detect whether the user has added water.

[0145] It is detected that the user chooses to add water manually and boil it again. Because there is too much water left in the kettle after the first boil (maybe 200ml-500ml), there are also a lot of residual minerals (such as calcium, magnesium) and nitrites. When water is added and boiled for the second time, the concentration of minerals and nitrites will increase. At this time, the water after boiling again is defined as the second state.

[0146] It is detected that the user did not add water manually. In this case, the user may have taken less water, and the water volume in the kettle may be 500ml-800ml. Because the user took the kettle to take water but did not heat it in time, the water temperature in the kettle dropped. The temperature sensor detected that the water temperature in the kettle was below 95°C. The user chose to reheat and boil it. At this time, the re-boiled water is defined as the third state.

[0147] The water quality in the first state can be considered as healthy water quality, while the second and third states are considered as poor water quality.

[0148] When water is added to the kettle, or the same kettle of water is boiled repeatedly, that is, when the water state in the kettle is detected to be in the second state or the third state for 3-5 consecutive times, that is, when the consecutive number of times the recorded drinking water is in the second state or the third state reaches the first number threshold, a second reminder message is issued to remind the user that the water quality in the kettle is not good and new water needs to be replaced and boiled again for drinking.

[0149] If the water state in the kettle is detected to be in the second state or the third state for more than 5 consecutive times, that is, the consecutive number of times the recorded drinking water is in the second state or the third state reaches the second number threshold, a third reminder message is issued, and heating needs to be stopped to prevent the user from continuing to heat the water in the kettle and causing the water quality to deteriorate, thereby endangering health risks.

[0150] The consecutive times are set to zero for the first time entering the second state or the third state. If the water volume is less than 200 ml after taking water, water is added to boil and the counting starts again.

[0151] When the user finishes taking water, the device will promptly remind the user to clean the scale in the kettle when shutting down to ensure the user's drinking water safety.
