Description

Technical Field

[0001] The present invention relates to the technical field of water output control of instant hot water drinking equipment, and in particular to a control method, a device, a computer-readable storage medium and an instant hot water drinking equipment. Background Art

[0002] At present, instant hot drinking water equipment has entered the mainstream market. Instant hot drinking water equipment has the technical characteristics of "instant water out" and automatic water discharge, and the accuracy of the water output is an important manifestation of product intelligence.

[0003] Currently, quantitative water extraction for instant hot drinking water equipment is usually achieved by connecting sensors such as pulse flow meters to the water outlet pipe. However, this method increases the cost of the equipment on the one hand, and connecting external devices to the water outlet pipe is prone to polluting the water source on the other hand. Summary of the invention

[0004] In view of this, the present invention provides a control method, device, computer-readable storage medium and instant hot water drinking equipment to solve the problem that the quantitative water intake solution adopted by the existing instant hot water drinking equipment not only increases the equipment cost but also easily pollutes the water source.

[0005] A first aspect of the present invention provides a control method for controlling the water output of an instant hot water drinking device, the control method comprising the following steps:

[0006] Control instant hot water equipment to start water discharge;

[0007] Obtaining a real-time driving voltage of a water pump of the instant hot water drinking equipment;

[0008] Substituting the real-time driving voltage into the water outlet flow rate-water pump voltage correspondence diagram of the instant hot water drinking device established in the database to obtain the real-time water outlet flow rate of the instant hot water drinking device;

[0009] The obtained real-time water outlet flow rate of the instant hot drinking water device is accumulated per unit time to convert the water outlet volume of the instant hot drinking water device;

[0010] Determine whether the water output of the instant hot drinking water device is greater than or equal to the target water intake volume;

[0011] If yes, the instant hot water drinking device is controlled to stop discharging water.

[0012] Beneficial effect: The control method of the present application obtains the real-time driving voltage of the water pump of the instant hot drinking water equipment, and substitutes the obtained real-time driving voltage into the water outlet flow rate-water pump voltage correspondence diagram of the database to obtain the real-time water outlet flow rate of the instant hot drinking water equipment, and then accumulates the real-time water outlet flow rate per unit time to obtain the water outlet volume of the instant hot drinking water equipment, and then compares the water outlet volume with the target water intake volume. If the water outlet volume is greater than or equal to the target water intake volume, the instant hot drinking water equipment is controlled to stop discharging water, thereby realizing quantitative water intake of the instant hot drinking water equipment. In this process, the real-time driving voltage of the water pump is used to obtain the real-time water outlet flow rate of the hot drinking water equipment, and the water outlet volume is obtained by accumulating the real-time water outlet flow rate, without setting up external devices such as flow meters to detect the water flow rate, which not only saves equipment costs but also avoids the pollution of water sources by external devices.

[0013] In some embodiments, the control method further comprises the following steps:

[0014] A corresponding relationship diagram between the water outlet flow rate and the water pump voltage of the instant hot water drinking equipment is established and saved in a database.

[0015] Beneficial effect: The established water outlet flow rate-water pump voltage correspondence diagram of the instant hot drinking water equipment can be used as reference data for the instant hot drinking water equipment to achieve quantitative water extraction, which is very convenient.

[0016] In some embodiments, the step of establishing a corresponding relationship diagram between the water flow rate and the water pump voltage of the instant hot water drinking device and saving it to a database includes:

[0017] Obtaining the heating status of the instant hot water drinking equipment;

[0018] Determining whether the heating state of the instant hot water drinking equipment is in a stable state;

[0019] If yes, obtain the heating power P of the instant hot water drinking equipment and the temperature difference ΔT before and after water heating;

[0020] The water outlet flow rate V of the instant hot water device is obtained according to the heating power P of the instant hot water device and the temperature difference ΔT before and after the water is heated;

[0021] Collecting the water pump voltage of the instant hot water drinking equipment;

[0022] Repeat the above steps to obtain multiple groups of water outlet flow rate V and water pump voltage values ​​of the instant hot water drinking equipment;

[0023] According to the obtained multiple groups of water outlet flow rate V and water pump voltage values ​​of the instant hot water drinking equipment, a water outlet flow rate-water pump voltage correspondence diagram of the instant hot water drinking equipment is established and saved in the database.

[0024] Beneficial effect: First determine whether the heating state of the instant hot drinking water equipment is in a stable state. After determining that the heating state of the instant hot drinking water equipment is in a stable state, obtain the heating power P of the instant hot drinking water equipment and the temperature difference △T before and after the water is heated, so as to ensure that the obtained heating power P and the temperature difference △T before and after the water is heated are in a relatively stable range to reduce the error, so that the water outlet flow rate V of the instant hot drinking water equipment obtained according to the heating power P and the temperature difference △T before and after the water is heated is a stable and reliable value, thereby ensuring the accuracy and reliability of the collected data. By obtaining multiple sets of water outlet flow rate V and water pump voltage values, a water outlet flow rate-water pump voltage correspondence diagram of the instant hot drinking water equipment can be established and saved in a database for convenient quantitative water extraction.

[0025] In some embodiments, the step of determining whether the heating state of the instant hot water drinking device is in a stable state includes:

[0026] Obtain the outlet water temperature T1 of the instant hot water drinking equipment;

[0027] Determine whether the absolute value of the difference between the target temperature T2 and the outlet water temperature T1 of the instant hot water drinking device is within a preset range;

[0028] If yes, it is concluded that the heating state of the instant hot water drinking equipment is in a stable state.

[0029] Beneficial effect: First, obtain the water outlet temperature T1 of the instant hot drinking water equipment. When the absolute value of the difference between the target temperature T2 of the instant hot drinking water equipment and the water outlet temperature T1 is within the preset range, it means that the water outlet temperature T1 of the instant hot drinking water equipment is near the target temperature T2 and the fluctuation range is small. It can be determined that the instant hot drinking water equipment is in a stable state.

[0030] In some embodiments, in the step of determining whether the absolute value of the difference between the target temperature T2 and the outlet water temperature T1 of the instant hot water drinking equipment is within a preset range, the preset range is 1°C to 10°C.

[0031] Beneficial effect: By setting the preset range of the absolute value of the difference between the target temperature T2 and the outlet water temperature T1 of the instant hot water drinking equipment within a suitable range of 1°C to 10°C, it can ensure that the outlet water temperature T1 of the instant hot water drinking equipment is within a controllable range from the target temperature T2, and also ensure the judgment accuracy.

[0032] In some embodiments, the step of obtaining the water flow rate V of the instant hot water device according to the heating power P of the instant hot water device and the temperature difference ΔT before and after water heating comprises:

[0033] Substituting the heating power P and the temperature difference ΔT before and after water heating into the following formula, the water outlet flow rate V of the instant hot water drinking device is obtained:

[0034]

[0035] Among them, P is heating power, △T is temperature difference before and after water heating, C is specific heat capacity of water, ρ is water density, η is heating efficiency, Q is total water flow, t is water flow time, and V = Q / t.

[0036] Beneficial effect: According to the physical law of conservation of heat, by substituting the obtained heating power P and the temperature difference △T before and after water heating into the above formula, and the other parameters C, ρ, η in the formula are all known, the value of Q / t can be calculated, that is, the value of the water outlet flow rate V.

[0037] In some embodiments, if the above is the case, in the step of obtaining the heating power P of the instant hot drinking water equipment and the temperature difference ΔT before and after water heating, the heating power P is obtained through a heating voltage and current detection circuit.

[0038] Beneficial effect: The heating power P is obtained through the heating voltage and current detection circuit, which can ensure the reliability of the heating power P of the instant hot water drinking equipment.

[0039] In some embodiments, if the above is the case, in the step of obtaining the heating power P of the instant hot drinking water equipment and the temperature difference ΔT before and after water heating, the temperature difference ΔT before and after water heating is obtained by collecting the temperature of the water flow of the instant hot drinking water equipment after heating and before heating and making the difference.

[0040] Beneficial effect: The temperature difference △T before and after water heating is obtained by collecting the temperature of the water flow of the instant hot water device after heating and before heating and making the difference, which can ensure the reliability of the temperature difference △T before and after water heating of the instant hot water device.

[0041] In some embodiments, in the step of establishing a water outlet flow rate-water pump voltage correspondence diagram of the instant hot water drinking equipment and saving it to a database, the water outlet flow rate-water pump voltage correspondence diagram is a straight line or a curve diagram.

[0042] Beneficial effect: By forming a water outlet flow rate-water pump voltage correspondence diagram into a straight line or a curve diagram, it is convenient for users to check the water outlet flow rate-water pump voltage correspondence of the instant hot water drinking equipment at a glance.

[0043] A second aspect of the present invention provides a control device, which is used to implement the above control method, and the control device includes:

[0044] A control module, used to control the instant hot water drinking device to start or stop discharging water;

[0045] An acquisition module, used for acquiring the real-time driving voltage of the instant hot water drinking device;

[0047] The judgment module is used to judge whether the water output of the instant hot drinking water device is greater than or equal to the target water intake volume.

[0048] Beneficial effects: The control device provided in the present application is used to implement the above-mentioned control method, and therefore has all the technical effects of the above-mentioned control method. The specific technical effects of the control device here will not be repeated here.

[0061] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Therefore, they cannot be understood as limitations on the present invention.

[0063] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0065] Combine the following Figures 1 to 5 , describing an embodiment of the present invention.

[0066] like Figure 1 As shown, according to an embodiment of the present invention, on the one hand, a control method is disclosed for controlling the water output of an instant hot water drinking device, the control method comprising the following steps:

[0067] Control the instant hot water equipment to start water discharge;

[0068] Obtain the real-time driving voltage of the water pump of the instant hot water drinking equipment;

[0069] Substituting the real-time driving voltage into the water outlet flow rate-water pump voltage correspondence diagram of the instant hot water drinking equipment established in the database to obtain the real-time water outlet flow rate of the instant hot water drinking equipment;

[0070] The obtained real-time water outlet flow rate of the instant hot water drinking equipment is accumulated per unit time to convert it into the water outlet volume of the instant hot water drinking equipment;

[0071] Determine whether the water output of the instant hot water drinking equipment is greater than or equal to the target water intake;

[0072] If yes, the instant hot water drinking device is controlled to stop discharging water.

[0073] The control method of this embodiment obtains the real-time driving voltage of the water pump of the instant hot drinking water device, and substitutes the obtained real-time driving voltage into the water outlet flow rate-water pump voltage correspondence diagram of the database to obtain the real-time water outlet flow rate of the instant hot drinking water device, and then accumulates the real-time water outlet flow rate per unit time to obtain the water outlet volume of the instant hot drinking water device, and then compares the water outlet volume with the target water intake volume. If the water outlet volume is greater than or equal to the target water intake volume, the instant hot drinking water device is controlled to stop discharging water, thereby realizing quantitative water intake of the instant hot drinking water device. In this process, the real-time driving voltage of the water pump is used to obtain the real-time water outlet flow rate of the hot drinking water device, and the water outlet volume is obtained by accumulating the real-time water outlet flow rate, without setting external devices such as flow meters to detect the water flow rate, which saves equipment costs and avoids the pollution of water sources by external devices.

[0074] In some embodiments, the control method further comprises the following steps:

[0075] Establish the water outlet flow rate-water pump voltage correspondence diagram of the instant hot water drinking equipment and save it to the database.

[0076] The established water outlet flow rate-water pump voltage correspondence diagram of the instant hot drinking water equipment can be used as reference data for the instant hot drinking water equipment to achieve quantitative water extraction, which is very convenient.

[0077] In some embodiments, the step of establishing a water flow rate-water pump voltage correspondence diagram of the instant hot water drinking device and saving it to a database includes:

[0078] Get the heating status of the instant hot water device;

[0079] Determine whether the heating state of the instant hot water drinking equipment is in a stable state;

[0080] If yes, obtain the heating power P of the instant hot water equipment and the temperature difference △T before and after water heating;

[0081] The water flow rate V of the instant hot water equipment is obtained based on the heating power P of the instant hot water equipment and the temperature difference △T before and after the water is heated;

[0082] Collect the water pump voltage of instant hot water equipment;

[0083] Repeat the above steps to obtain the water flow rate V and water pump voltage values ​​of multiple groups of instant hot water drinking equipment;

[0084] According to the obtained values ​​of the water outlet flow rate V and the water pump voltage of the multiple groups of instant hot water drinking equipment, a corresponding relationship diagram of the water outlet flow rate-water pump voltage of the instant hot water drinking equipment is established and saved in the database.

[0085] In this embodiment, it is first determined whether the heating state of the instant hot drinking water device is in a stable state. After determining that the heating state of the instant hot drinking water device is in a stable state, the heating power P of the instant hot drinking water device and the temperature difference △T before and after the water is heated are obtained to ensure that the obtained heating power P and the temperature difference △T before and after the water is heated are in a relatively stable range to reduce errors, so that the water outlet flow rate V of the instant hot drinking water device obtained according to the heating power P and the temperature difference △T before and after the water is heated is a stable and reliable value, thereby ensuring the accuracy and reliability of the collected data. By obtaining multiple groups of water outlet flow rate V and water pump voltage values, a water outlet flow rate-water pump voltage correspondence diagram of the instant hot drinking water device can be established and saved in a database for convenient quantitative water extraction.

[0086] In some embodiments, the step of determining whether the heating state of the instant hot water drinking device is in a stable state includes:

[0087] Get the water outlet temperature T1 of the instant hot water device;

[0088] Determine whether the absolute value of the difference between the target temperature T2 of the instant hot water drinking device and the water outlet temperature T1 is within a preset range;

[0089] If yes, it is concluded that the heating state of the instant hot water drinking equipment is in a stable state.

[0090] First, obtain the water outlet temperature T1 of the instant hot water drinking equipment. When the absolute value of the difference between the target temperature T2 of the instant hot water drinking equipment and the water outlet temperature T1 is within the preset range, it means that the water outlet temperature T1 of the instant hot water drinking equipment is near the target temperature T2 and the fluctuation range is small. It can be determined that the instant hot water drinking equipment is in a stable state.

[0091] It should be noted that the target temperature T2 is a preset water intake temperature, which is set according to user needs and is not specifically limited in this embodiment.

[0092] For example, a user who wants to make tea sets the target temperature T2 to 100°C;

[0093] Users who need to make milk powder set the target temperature T2 to 45℃~55℃.

[0094] It can be further understood that the absolute value of the difference between the target temperature T2 and the outlet water temperature T1 is set to X. The smaller X is, the closer the outlet water temperature T1 of the instant hot water drinking device is to the target temperature T2. On the contrary, the larger X is, the greater the difference between the outlet water temperature T1 of the instant hot water drinking device and the target temperature T2. Therefore, in theory, the smaller X is, the higher the accuracy is.

[0095] In some embodiments, in the step of determining whether the absolute value of the difference between the target temperature T2 and the outlet water temperature T1 of the instant hot water drinking device is within a preset range, the preset range is 1°C to 10°C.

[0096] By setting the preset range of the absolute value of the difference between the target temperature T2 and the outlet water temperature T1 of the instant hot water drinking equipment within an appropriate range, it can ensure that the outlet water temperature T1 of the instant hot water drinking equipment is within a controllable range from the target temperature T2 and ensure the judgment accuracy.

[0097] Specifically, based on the absolute value of the difference between the target temperature T2 and the outlet water temperature T1 being X, it is determined whether X is between 1°C and 10°C.

[0098] Illustratively, X is between 1°C and 10°C, which may be 1°C, 2°C, 3°C, 4°C, 5°C, 6°C, 7°C, 8°C, 9°C or 10°C, etc., and this embodiment does not make any specific limitation.

[0099] For ease of understanding, this embodiment uses an example. For example, the target temperature T2 of the instant hot water drinking device is 100°C. When the water outlet temperature T1 of the instant hot water drinking device is between 90°C and 110°C, we can determine that the heating state of the instant hot water drinking device is in a stable state.

[0100] For another example, the target temperature T2 of the instant hot water drinking equipment is 100°C, the water outlet temperature T1 of the instant hot water drinking equipment is 95°C, |T2-T1|=|100°C-95°C|=X=5°C, 5°C is between 1°C and 10°C, so we can judge that the heating state of the hot water drinking equipment is in a stable state.

[0101] In some embodiments, the step of obtaining the water outlet flow rate V of the instant hot water device according to the heating power P of the instant hot water device and the temperature difference ΔT before and after water heating comprises:

[0102] Substitute the heating power P and the temperature difference △T before and after water heating into the following formula to obtain the water flow rate V of the instant hot water equipment:

[0103]

[0104] Among them, P is heating power, △T is temperature difference before and after water heating, C is specific heat capacity of water, ρ is water density, η is heating efficiency, Q is total water flow, t is water flow time, and V = Q / t.

[0105] By substituting the obtained heating power P and the temperature difference △T before and after water heating into the above formula, and the other parameters C, ρ, and η in the formula are all known, the value of Q / t can be calculated, which is the value of the water outlet flow rate V.

[0106] It should be noted here that the above formula is based on the physical law of conservation of heat, and mainly relies on the work done by the heating element to increase the outlet water temperature.

[0107] In some embodiments, if yes, in the step of obtaining the heating power P of the instant drinking water equipment and the temperature difference ΔT before and after water heating, the heating power P is obtained through a heating voltage and current detection circuit.

[0108] The heating power P is obtained through a heating voltage and current detection circuit, which can ensure the reliability of the heating power P of the instant hot water drinking equipment.

[0109] Since the method of obtaining the heating power P through the heating voltage and current detection circuit is a prior art, it will not be described in detail in this embodiment.

[0110] In some embodiments, if yes, in the step of obtaining the heating power P of the instant drinking water equipment and the temperature difference ΔT before and after water heating, the temperature difference ΔT before and after water heating is obtained by collecting the temperature of the water flow of the instant drinking water equipment after heating and before heating and making the difference.

[0111] The temperature difference △T before and after water heating is obtained by collecting the temperature of the water flow of the instant drinking water equipment after heating and before heating and making the difference, which can ensure the accuracy and reliability of the temperature difference △T before and after water heating of the instant drinking water equipment.

[0112] Since the method of collecting the temperatures of the water flow of the instant hot drinking water device before and after heating and making the difference to obtain the temperature difference ΔT before and after water heating is a prior art, it will not be described in detail in this embodiment.

[0113] Specifically, the instant drinking water equipment heats the water through the internal heating element. Temperature sensing bags can be set both upstream and downstream of the water flow of the heating element. The temperature of the water flow before and after heating by the heating element is detected by the temperature sensing bags, and the temperature difference △T before and after the water heating can be obtained by subtracting the temperature values ​​detected by the temperature sensing bags.

[0114] It should be noted that the temperature of the water flow after being heated by the heating element is usually higher than the temperature of the water flow before being heated by the heating element. Therefore, in order to ensure that the temperature difference △T before and after the water is heated is a positive value, the temperature value of the water flow after being heated by the heating element is subtracted from the temperature value of the water flow before being heated by the heating element to obtain the difference △T between the two.

[0115] In the present embodiment, in the step of collecting the water pump voltage of the instant hot drinking water device, the water pump voltage of the instant hot drinking water device can be detected by a voltage detection pen, but is not limited to this. For example, in other embodiments, the water pump voltage of the instant hot drinking water device can also be obtained by detecting the water pump current of the instant hot drinking water device and then calculating it by a voltage calculation formula.

[0116] In some embodiments, in the step of establishing a water outlet flow rate-water pump voltage correspondence diagram of the instant hot water drinking equipment and saving it to a database, the water outlet flow rate-water pump voltage correspondence diagram is a straight line or a curve diagram.

[0117] By forming a water outlet flow rate-water pump voltage correspondence diagram into a straight line or a curve diagram, it is convenient for users to check the water outlet flow rate-water pump voltage correspondence of the instant hot water drinking equipment at a glance.

[0118] Preferably, the water outlet flow rate-water pump voltage correspondence diagram of the instant hot water drinking equipment is made into a curve graph, but is not limited to this. For example, in other embodiments, the water outlet flow rate-water pump voltage correspondence diagram of the instant hot water drinking equipment can also be made into a straight line graph.

[0119] Furthermore, in some embodiments, the step of controlling the instant hot drinking water device to start discharging water includes controlling the instant hot drinking water device to start, and starting to heat the water flow, through the control module 101 .

[0120] That is to say, when controlling the instant hot water drinking device to start discharging water, the user has set a target water intake temperature and a target water intake volume.

[0121] In some embodiments, in the step of obtaining the real-time driving voltage of the water pump of the instant hot drinking water device, a voltage detection sensor may be provided to detect and feed back the real-time driving voltage of the water pump of the instant hot drinking water device.

[0122] In some embodiments, the obtained real-time water flow rate of the instant hot water device is accumulated per unit time to convert the water output of the instant hot water device. Specifically, the real-time water flow rate of the instant hot water device in a number of unit times can be added to obtain the water output of the instant hot water device in a period of water output time.

[0123] For ease of understanding, this embodiment uses an example, where the unit time is calculated in seconds. For example, in the first second, the real-time water outlet flow rate of the instant hot drinking water device is 50 ml / S, and in the second second, the real-time water outlet flow rate of the instant hot drinking water device is 80 ml / S. In the third second, the real-time water outlet flow rate of the instant hot drinking water device is 100 ml / S. Thereafter, the real-time water outlet flow rate of the instant hot drinking water device is maintained at 100 ml / S. It can be concluded that the water output of the instant hot drinking water device within several seconds of continuous water output is 50 ml+80 ml+100 ml…+100 ml.

[0124] In some embodiments, a step is performed to determine whether the water output of the instant hot drinking water device is greater than or equal to the target water intake volume. When it is determined that the water output of the instant hot drinking water device is greater than or equal to the target water intake volume, indicating that the water output at this time has met the user's water intake demand, the instant hot drinking water device is controlled to stop outputting water.

[0125] Since in actual use, the water output of the instant hot drinking water device is mostly not exactly equal to the target water intake volume, and the water output may be slightly more than the target water intake volume, the present application sets the judgment standard as the water output of the instant hot drinking water device is greater than or equal to the target water intake volume, thereby increasing the control judgment conditions, reducing the control difficulty, and avoiding overflow due to the instant hot drinking water device continuing to discharge water while the water output is greater than the target water intake volume.

[0126] For ease of understanding, this embodiment provides the following example. For example, the target water intake volume of the instant hot drinking water device is set to 500ml. When the water output volume of the instant hot drinking water device is calculated to be 50ml+80ml+100ml...+100ml=510ml, 510ml>500ml, it means that the water output volume meets the user's water intake demand, and therefore the instant hot drinking water device is controlled to stop outputting water.

[0127] Of course, in other embodiments, the target water intake volume of the instant hot water drinking device can be changed according to user needs and is not limited to this embodiment. For example, the target water intake volume can also be set to 200ml or 300ml.
