[0002] In winter, for self-heating households, in order to avoid energy waste and ensure safety, users often turn off the indoor heat source when they go out. However, when users are out for a long time and turn off the heat source, it is easy to cause the indoor temperature to be too low. When the indoor temperature drops to 0℃ or below, it is very easy for the water in the faucet, shower, water pipe and other water parts to freeze, affecting the user's use. In serious cases, it may even rupture the water parts and cause water leakage. Summary of the invention

[0003] One object of the present invention is to solve the problem that water parts in existing self-heating households are prone to freezing.

[0004] A further object of the present invention is to reduce energy consumption while ensuring that water parts do not freeze.

[0005] To achieve the above object, the present invention provides, in a first aspect, a control method for preventing water in a water component from freezing, comprising:

[0006] Acquire the temperature of the water component in real time and record it as the current temperature;

[0007] Determining whether the current temperature is less than or equal to a critical temperature at which water freezes;

[0008] If it is less than or equal to, determining whether there is a first heating device in the first room where the water piece is located;

[0009] If present, the first heating device is controlled to operate.

[0010] Optionally, the control method further includes:

[0011] If it does not exist, obtain the door status of the first room;

[0012] If the door is in an open state, determining whether there is a second heating device in a second room that shares the door with the first room;

[0013] If present, the second heating device is controlled to operate.

[0014] Optionally, the first heating device is an electric heater or a bathroom heater; and / or, the second heating device is an air conditioner.

[0015] Optionally, the control method further includes:

[0016] If the current temperature reaches the preset temperature, all heating devices are controlled to stop.

[0017] Optionally, the water component is a faucet; and / or, the preset temperature is greater than or equal to the critical temperature.

[0018] Optionally, when determining whether the current temperature is less than or equal to a critical temperature at which water freezes, the control method further comprises: issuing a prompt message to remind a user that there is a risk of water in the water element freezing.

[0019] Optionally, the control method further includes:

[0020] When receiving the abort instruction, the execution is aborted;

[0021] After the execution of the first preset time period is suspended or when a continuing instruction is received, the step of obtaining the temperature of the water component in real time is re-executed.

[0022] Optionally, the control method further includes:

[0023] If the working times of the first heating device within the second preset time reaches the preset times, the heating power of the first heating device is gradually reduced until the working times of the first heating device within the second preset time is less than the preset times.

[0024] In a second aspect, the present invention provides a storage medium storing a machine executable program, wherein the machine executable program, when executed by a processor, can implement any control method described in the first aspect.

[0025] In a third aspect, the present invention provides a control device for preventing water from freezing in a water part, comprising a processor and a memory, wherein a machine executable program is stored in the memory, and when the processor executes the machine executable program, the control method described in any one of the first aspects can be implemented.

[0026] Based on the foregoing description, those skilled in the art can understand that, in the aforementioned technical solution of the present invention, the temperature of the water piece is obtained in real time and recorded as the current temperature; then it is determined whether the current temperature is less than or equal to the critical temperature for freezing of water; when it is less than or equal to, it is determined whether there is a first heating device in the first room where the water piece is located; if there is, the first heating device is controlled to work to heat the first room, thereby directly or indirectly heating the water piece to prevent the water in the water piece from freezing. Therefore, the present invention overcomes the problem that the water pieces in the existing self-heating households are prone to freezing.

[0027] Furthermore, when the number of times the first heating device works within the second preset time reaches the preset number, the heating power of the first heating device is automatically adjusted by gradually reducing the heating power of the first heating device until the number of times the first heating device works within the second preset time is less than the preset number, so as to reduce the energy consumption of the first heating device while ensuring that the water parts do not freeze. Specifically, through this technical means, the heating power of the first heating device can be gradually reduced, the working time can be gradually prolonged, and the first room can be heated at low power and stably, which can keep the water parts above the critical temperature for freezing water, and avoid the water parts being too hot, which would cause energy waste.

[0028] Furthermore, if there is no first heating device in the first room where the water piece is located, by obtaining the door status of the first room; and when the door is in an open state, it is determined whether there is a second heating device in the second room sharing the door with the first room; if there is, the second heating device is controlled to work, so that the water piece can be heated with the help of the heating devices in other rooms. Therefore, the present invention also ensures that the water piece in the room without heating devices (such as the kitchen, balcony) will not freeze.

[0041] like Figure 1 As shown, in the first embodiment of the present invention, the control method for preventing water in the water element from freezing includes:

[0042] Step S110, obtaining the temperature of the water component in real time and recording it as the current temperature.

[0043] In some embodiments of the present invention, the temperature of the water component can be directly obtained by setting a temperature sensor on the water component, or the temperature of the water component can be indirectly obtained by detecting the temperature in the room where the water component is located (ie, the first room described below).

[0044] The water parts include any feasible water-conducting components or water-storing components such as faucets, water pipes, shower heads, and water pipe valves.

[0045] In some embodiments of the present invention, the water component is preferably a faucet, and further preferably a smart faucet equipped with a temperature sensor and a communication module.

[0046] Step S120, determining whether the current temperature is less than or equal to the critical temperature for freezing of water.

[0047] Those skilled in the art will appreciate that when the current temperature is less than or equal to the critical temperature, the water in the water element is at risk of freezing. Accordingly, the critical temperature may be any feasible temperature, such as 0°C, -0.5°C, 1°C, etc.

[0048] Step S130: If it is less than or equal to, determine whether there is a first heating device in the first room where the water piece is located.

[0049] In the present invention, the first room can be any feasible room such as a bathroom, a kitchen, a balcony, etc.

[0050] Among them, the first heating device is any feasible device with heating function, such as electric heater, small sun, bathroom heater, etc.

[0051] Step S140: if present, control the first heating device to operate.

[0052] Specifically, when there is one first heating device, the first heating device is controlled to work. When there are at least two first heating devices, the two first heating devices can be controlled to work simultaneously; or one with a larger or smaller power can be controlled to work first, and after a period of time (for example, 10 minutes, 30 minutes, 70 minutes, or any feasible time), if the current temperature is still less than or equal to the critical temperature, another first heating device is turned on until all the first heating devices are turned on.

[0053] For example, if there are at least two first heating devices, the first heating devices are turned on in a set order. After a period of time (for example, 10 minutes, 30 minutes, 70 minutes, or any other feasible time), if the current temperature is still less than or equal to the critical temperature, another first heating device is turned on until all the first heating devices are turned on or the current temperature is greater than the critical temperature.

[0054] The set order is the order set by the user, which can be the order from high to low security, the order from small to large power, or the order from large to small power.

[0055] Based on the above description, those skilled in the art can understand that some embodiments of the present invention can timely turn on the first heating device in the first room when there is a risk of freezing of water, thereby preventing the water from freezing, thus overcoming the problem of easy freezing of water in existing self-heating homes.

[0056] It should be noted that the above-mentioned embodiment of the present invention is only a basic embodiment of the present invention. In other embodiments of the present invention, those skilled in the art may also adjust, optimize and configure the schemes and steps in the above-mentioned embodiments as needed to achieve further technical effects. Other embodiments of the present invention different from the above-mentioned embodiments will be described in conjunction with the accompanying drawings hereinafter. Of course, those skilled in the art may also make appropriate modifications to the execution order, operating conditions and quantity of the steps in the embodiments to be described hereinafter according to actual needs. The modified embodiments do not deviate from the technical concept and / or technical principle of the present invention and should still fall within the scope of protection of the present invention.

[0057] Refer to the following Figure 2 The control method for preventing water from freezing in a water part in some other embodiments of the present invention will be described in detail. For the convenience of description, only the differences between some other embodiments and some embodiments described above will be described below, and the similarities can be found in the above text.

[0058] like Figure 2 As shown, in some other embodiments of the present invention, the control method for preventing water from freezing in the water element further includes, after step S120:

[0059] Step S210: If there is no first heating device in the first room where the water component is located, obtain the door status of the first room.

[0060] In some other embodiments of the present invention, a door opening and closing sensor can be separately configured for the door to detect the door status of the first room through the door opening and closing sensor; the door status of the first room can also be detected through other devices (such as a sweeping robot, a camera, etc.).

[0061] Step S220: If the door is open, determine whether there is a second heating device in the second room that shares the door with the first room.

[0062] In some other embodiments of the present invention, the second heating device may be any feasible heating device such as an air conditioner, an electric heater, etc.

[0063] Step S230: if it exists, control the second heating device to operate.

[0064] It is understood by those skilled in the art that the second heating device can heat the air in the second room when it is in operation. The heat of the air in the second room will diffuse into the first room, thereby achieving heating of the first room.

[0065] Based on the foregoing description, relative to some of the embodiments described above, some other embodiments of the present invention also prevent water items in rooms that do not have heating equipment (such as kitchens, balconies) from freezing.

[0066] Refer to the following Figure 3 The control method for preventing water from freezing in a water component in some further embodiments of the present invention will be described in detail.

[0067] like Figure 3 As shown, in some further embodiments of the present invention, the control method for preventing water in the water element from freezing includes:

[0068] Step S301, obtaining the current temperature of the water component in real time, for details please refer to the description of step S110 above.

[0069] Step S302, determine whether the current temperature is less than or equal to the critical temperature for freezing of water. If so, execute steps S303 and S309; ​​if so, execute step S301.

[0070] Step S303, determining whether there is a first heating device in the first room where the water piece is located. If yes, executing step S304; if not, executing step S305.

[0071] Step S304, controlling the first heating device to operate, for details please refer to the above description of step S140.

[0072] Step S305, obtaining the door status of the first room, for details please refer to the above description of step S210.

[0073] Step S306, if the door is in an open state, determine whether there is a second heating device in the second room that shares the door with the first room. For details, please refer to the description of step S220 above.

[0074] Step S307, if it exists, control the second heating device to operate, for details please refer to the description of step S330 above.

[0075] Step S308: During the execution of step S304 or step S307, if the current temperature reaches the preset temperature, all heating devices are controlled to stop working.

[0076] Those skilled in the art can understand that when the current temperature reaches the preset temperature, it means that the temperature of the water piece is high enough and the water inside will not freeze in a short time.

[0077] Wherein, the preset temperature is greater than or equal to the critical temperature.

[0078] Preferably, the preset temperature is any feasible temperature such as 1°C, 2°C, 3.5°C higher than the critical temperature, so that the water in the water piece will not freeze in a short time after all heating devices are stopped.

[0079] Step S309, when determining whether the current temperature is less than or equal to the critical temperature for freezing of water, a prompt message is issued to remind the user that there is a risk of freezing of water in the water part.

[0080] The prompt information may be information sent to the user's mobile phone, or may be text information, sound information or light information sent to other terminal devices.

[0081] In some other embodiments of the present invention, after receiving the prompt information, if the user is at home, he can check whether the doors and windows of the first room are closed. If not, he can close them to reduce the loss of heat. He can also check whether the door between the first room (such as the bathroom) and the second room (such as the living room or bedroom) is open. If not, he can open it to heat the first room with the heat from the second room. After the user performs the above operations, he can send a stop instruction through a mobile phone or a specific terminal device (such as a human-computer interaction speaker) to stop the first heating device from working. In particular, after the user closes the doors and windows, the heat loss in the first room is reduced, and the temperature may rise above the critical temperature, so that the water parts are no longer frozen.

[0082] Step S310: During the execution of step S304 or step S307, if a stop instruction is received, the execution is stopped.

[0083] The termination instruction may be sent by the user via a mobile phone or a specific terminal device (eg, a human-computer interaction speaker).

[0084] Step S311, after suspending execution for the first preset time period or when receiving a continue instruction, re-execute step S301.

[0085] The first preset duration may be any feasible duration, such as 30 minutes, 60 minutes, 90 minutes, etc.

[0086] In some further embodiments of the present invention, after the execution of the first preset time period is terminated, especially after the user closes the doors and windows of the first room, the temperature in the first room will reach a new equilibrium, which may be higher than the critical temperature or may be less than or equal to the critical temperature.

[0087] The continue instruction may be sent by the user via a mobile phone or a specific terminal device (eg, a human-computer interaction speaker).

[0088] Step S312, when it is detected that the first heating device works for the first time in this control cycle, start timing and count the number of times the first heating device works.

[0089] Step S313, if the working times of the first heating device within the second preset time reaches the preset times, the heating power of the first heating device is gradually reduced until the working times of the first heating device within the second preset time is less than the preset times.

[0090] Among them, the second preset duration is the control period of the first heating device, which can be any feasible duration such as 4 hours, 10 hours, 24 hours, 30 hours, 3 days, 5 days, etc.

[0091] The preset number of times may be any feasible number such as 3 times, 5 times, 10 times, etc.

[0092] In step S313, there is one first heating device. Alternatively, those skilled in the art may also set multiple first heating devices as needed, and when gradually reducing the heating power of the first heating devices, reduce the heating power of one first heating device each time until the first heating device stops running, and then start to gradually reduce the heating power of another heating device, and so on.

[0093] The following is an illustration using a first heating device as an example.

[0094] When the first heating device has worked for a preset number of times within the second preset time period, the heating power of the first heating device is reduced by one level (for example, 5%, 10%, 20%, 20W, 100W, 200W, etc.), and then step S301 is re-executed.

[0095] Based on the foregoing description, those skilled in the art can understand that, in some other embodiments of the present invention, when the number of times the first heating device works within the second preset time reaches the preset number, the heating power of the first heating device is automatically adjusted by gradually reducing the heating power of the first heating device until the number of times the first heating device works within the second preset time is less than the preset number, so as to ensure that the water parts do not freeze while reducing the energy consumption of the first heating device. Specifically, through this technical means, the heating power of the first heating device can be gradually reduced, the working time can be gradually prolonged, and the first room can be heated at low power and stably, which can keep the water parts above the critical temperature for freezing of water, and avoid the water parts being too hot, which causes energy waste.

[0096] It should be noted that the control method in any of the above described embodiments can be implemented by a cloud server or a backend server; it can also be implemented by a specific terminal device, such as Figure 4 The control device shown in .
