A control system and a control method of a water heater proposed according to an embodiment of the present invention are described below with reference to the accompanying drawings.
FIG. 1 is a block schematic diagram of a control system for a water heater according to one embodiment of the present invention. In embodiments of the present invention, the water heater may include a tank water heater, an instant electric water heater, and the like.
As shown in fig. 1, a control system of a water heater according to an embodiment of the present invention includes: a plurality of waterflow monitoring units 100 and awater heater 200.

In an embodiment of the present invention, the preset threshold may be calibrated according to actual conditions, the water consumption point may be a hot water outlet point of the faucet, that is, a water outlet end connected to the hot water outlet of the water heater, and the detectingunit 110 may include a water flow sensor, where the water flow sensor in the detectingunit 110 may monitor water flow information of the water consumption point in real time. In other embodiments of the present invention, the preset threshold may be stored in a storage space of the control unit 120, where the storage space is not limited to an entity-based storage space, such as a hard disk, and the storage space may also be a storage space (cloud storage space) of a network hard disk connected to the control unit 120.
It should be understood that, in this embodiment, the water flow sensor may output the electrical pulse signal by sensing the flow of the water flow inside the water pipe where the water using point is located, wherein the higher the water flow is, the higher the pulse frequency is (i.e., the stronger the electrical pulse signal is), and if the water does not flow, the pulse frequency is not generated, i.e., the electrical pulse signal is not generated. Therefore, the detectingunit 110 can determine whether the water inside the water pipe where the water point is located flows according to the existence of the electrical pulse signal, that is, whether the hot water end in the faucet where the water point is located is opened, when the detectingunit 110 detects the electrical pulse signal, the control unit 120 can determine the magnitude of the water flow to the application water point according to the strength of the electrical pulse signal, and determine whether the water flow to the application water point reaches the preset threshold value according to the magnitude.
In addition, the position information on the water spot applied described in the above embodiments may be a position where a faucet for the water spot applied is located (e.g., a position of a kitchen sink, a position of an adult bath, a position of a baby bath, etc.). The position information on the water application point described in the above embodiments may be stored in the storage space of the corresponding control unit 120.
Thewater heater 200 is configured to receive the position information sent by the control unit 120 in the plurality of waterflow monitoring units 100, and adjust the water usage pattern of thewater heater 200 according to the position information. The water usage mode may include a kitchen mode, a shower mode, a baby bath mode, and the like. For example, if the location information received by thewater heater 200 is the location of the kitchen sink, thewater heater 200 may be controlled to enter the kitchen mode to operate.
It should be noted that, if thewater heater 200 receives a plurality of pieces of location information in sequence, the water usage mode of thewater heater 200 is adjusted according to the first received location information.
In one embodiment of the present invention, as shown in fig. 2, the waterflow monitoring unit 100 may further include a first wireless communication unit 130, and thewater heater 200 may include a second wireless communication unit 210, and thewater heater 200 communicates with the first wireless communication unit 130 of the waterflow monitoring unit 100 through the second wireless communication unit 210. Wherein, each of the first Wireless communication unit 130 and the second Wireless communication unit 210 may include one or more of RF (Radio Frequency), WIFI (Wireless broadband), bluetooth, and ZigBee (short range Wireless communication technology).
As shown in fig. 3, taking a water tank type water heater as an example, when a user opens ahot water valve 10 in a kitchen faucet, water in a water pipe upstream of thehot water valve 10 starts to flow, at this time, thedetection unit 110 may acquire an electric pulse signal, and then the control unit 120 determines the water flow rate near thehot water valve 10 according to the electric pulse signal, and calls a preset threshold from its own storage space, and determines whether the water flow rate near thehot water valve 10 reaches the preset threshold. If the control unit 120 determines that the water flow rate near thehot water valve 10 reaches the preset threshold, the control unit calls out the position information (for example, the position of the kitchen sink) of the water outlet point where thehot water valve 10 is located from its own storage space, and sends the position information to the second wireless communication unit 210 in thewater heater 200 through the first wireless communication unit 130.
When the second wireless communication unit 210 in thewater heater 200 receives the position information sent by the control unit 120, the position information is uploaded to the central processing unit 220 of thewater heater 200, and the central processing unit 220 adjusts the water usage mode of the water heater 200 (for example, to the kitchen mode) according to the position information.
In summary, the control system of the water heater provided by the embodiment of the invention enables the water heater to automatically adjust the water consumption mode according to the position of the water consumption point used by the user, so that manual adjustment by the user is not needed, and the user experience is improved.
Further, in an embodiment of the present invention, thewater heater 200 is further configured to monitor water flow information of the position information to the water application point after adjusting the water usage mode of thewater heater 200 according to the position information, control thewater heater 200 to enter a standby state if the water flow in the water flow information is zero, and control thewater heater 200 to maintain the current water usage mode if the water flow in the water flow information is not zero.
Specifically, after entering the kitchen mode, thewater heater 200 monitors the water flow information of the water usage point in the kitchen in real time (i.e., monitors whether the user is using the hot water of the water usage point), and if the water flow in the water flow information is zero (i.e., the user is using the hot water of the water usage point), thewater heater 200 maintains the water usage mode of the first water usage point even if another water usage point simultaneously turns on the water (hot water), so as to avoid the sudden temperature change caused by the simultaneous water usage of a plurality of water usage points. When the water consumption mode is closed after the water consumption of the water consumption point is finished, thewater heater 200 is unlocked to regulate the water consumption mode and can enter a standby state.
In an embodiment of the present invention, thewater heater 200 may further be configured to receive the water usage mode adjustment instruction through a remote controller, and adjust the water usage mode of thewater heater 200 according to the water usage mode adjustment instruction, so that the user can autonomously adjust the water usage mode of thewater heater 200 according to the user's own needs, thereby further improving the user experience.
To sum up, in the control system of the water heater according to the embodiment of the present invention, the detection unit in the water flow monitoring unit detects the water flow information flowing through the application water point, and controls the control unit in the water flow monitoring unit to determine whether the water flow to the application water point reaches the preset threshold according to the water flow information to the application water point, and when the water flow to the application water point reaches the preset threshold, the position information to the application water point is sent to the water heater, and the water heater receives the position information sent by the control units in the plurality of water flow monitoring units and adjusts the water usage mode of the water heater according to the position information. Therefore, the system enables the water heater to automatically adjust the water consumption mode according to the position of the water consumption point used by the user, so that manual adjustment of the user is not needed, and the user experience is improved.
FIG. 4 is a flow chart of a method of controlling a water heater according to one embodiment of the present invention. In embodiments of the present invention, the water heater may include a tank water heater, an instant electric water heater, and the like.
As shown in fig. 4, the control method of the water heater according to the embodiment of the present invention includes the following steps:
s1, the water flow monitoring units respectively provided at the plurality of water consumption points detect information on the flow rate of water flowing through the water consumption points.
In an embodiment of the present invention, the water consumption point may be a hot water outlet point of the faucet, that is, a water outlet end connected to the hot water outlet of the water heater, and the water flow monitoring unit may include a water flow sensor, wherein the water flow sensor in the water flow monitoring unit may monitor water flow information to the water consumption point in real time.
It should be understood that, in this embodiment, the water flow sensor may output the electrical pulse signal by sensing the flow of the water flow inside the water pipe where the water using point is located, wherein the higher the water flow is, the higher the pulse frequency is (i.e., the stronger the electrical pulse signal is), and if the water does not flow, the pulse frequency is not generated, i.e., the electrical pulse signal is not generated. Therefore, the water flow monitoring unit can judge whether the water in the water pipe where the water consumption point is located flows according to the existence of the electric pulse signal, namely whether the hot water end in the water faucet where the water consumption point is located is started.
And S2, the water flow monitoring unit judges whether the water flow of the application water point reaches a preset threshold value according to the water flow information of the application water point, and sends the position information of the application water point when the water flow of the application water point reaches the preset threshold value. Wherein, the preset threshold value can be calibrated according to the actual situation,
in other embodiments of the present invention, the preset threshold may be stored in a storage space of the water flow monitoring unit, where the storage space is not limited to a physical-based storage space, such as a hard disk, and the storage space may also be a storage space (cloud storage space) of a network hard disk connected to the water flow monitoring unit.
Specifically, when the water flow monitoring unit detects that the electric pulse signal exists, the water flow monitoring unit can determine the water flow to the application water point according to the strength of the electric pulse signal, call a preset threshold value from the storage space of the water flow monitoring unit, judge whether the water flow to the application water point reaches the preset threshold value, and then send the position information of the application water point to the water heater. Wherein, the water heater can carry out wireless communication with the water flow monitoring unit.
It should be noted that the position information of the water application point described in the above embodiments may be a position where a faucet of the water application point is located (for example, a position of a kitchen sink, a position of an adult bath, a position of a baby bath, and the like). The position information of the water application point described in the above embodiments may be stored in the storage space of the corresponding water flow monitoring unit.
And S3, the water heater receives the position information sent by the water flow monitoring unit and adjusts the water consumption mode of the water heater according to the position information. The water usage mode may include a kitchen mode, a shower mode, a baby bath mode, and the like. For example, if the location information received by the water heater is the location of the kitchen sink, the water heater may be controlled to enter the kitchen mode for operation.
It should be noted that, if the water heater receives a plurality of pieces of location information in sequence, the water usage mode of the water heater is adjusted according to the first received location information.
As shown in fig. 3, taking a water tank type water heater as an example, when a user opens a hot water valve in a kitchen faucet, water in a water pipe upstream of the hot water valve starts to flow, at this time, the water flow monitoring unit may acquire an electric pulse signal, determine the water flow near the hot water valve according to the electric pulse signal, call a preset threshold from its own storage space, and determine whether the water flow near the hot water valve reaches the preset threshold. If the water flow monitoring unit judges that the water flow near the hot water valve reaches the preset threshold value, the position information (for example, the position of a kitchen pool) of a water outlet point where the hot water valve is located is called out from the storage space of the water flow monitoring unit, and the position information is sent to the water heater through a wireless network.
When the water heater receives the position information sent by the water flow monitoring unit, the water using mode of the water heater is adjusted (for example, adjusted to the kitchen mode) according to the position information.
In summary, the control method of the water heater provided by the embodiment of the invention enables the water heater to automatically adjust the water consumption mode according to the position of the water consumption point used by the user, so that manual adjustment by the user is not needed, and the user experience is improved.
Further, in an embodiment of the present invention, the control method of the water heater further includes monitoring water flow information of the water point to which the position information is applied after the water usage mode of the water heater is adjusted according to the position information, controlling the water heater to enter a standby state if the water flow in the water flow information is zero, and controlling the water heater to maintain the current water usage mode if the water flow in the water flow information is not zero.
Specifically, after the water heater enters the kitchen mode, the water flow information of the water usage point in the kitchen is monitored in real time (i.e., whether a user uses hot water of the water usage point is monitored), and if the water flow in the water flow information is zero (i.e., the user uses hot water of the water usage point), even if another water usage point simultaneously turns on water (hot water), the water heater keeps the water usage mode of the first water usage point, so that the temperature sudden change is avoided when a plurality of water usage points simultaneously use water. And when the water consumption mode is closed after the water consumption of the water consumption point is finished, the water heater is unlocked to regulate the water consumption mode and can enter a standby state.
In an embodiment of the present invention, the control method of the water heater further includes that the water heater receives the water usage mode adjustment instruction through the remote controller, and adjusts the water usage mode of the water heater according to the water usage mode adjustment instruction, so that the user can autonomously adjust the water usage mode of thewater heater 200 according to the own requirement, and the user experience is further improved.
To sum up, in the control method of the water heater according to the embodiment of the present invention, the water flow monitoring units respectively disposed at the water consumption points are used to detect the water flow information of the application water point, and determine whether the water flow of the application water point reaches the preset threshold according to the water flow information of the application water point, and send the position information of the application water point when the water flow of the application water point reaches the preset threshold, and then the water heater receives the position information sent by the water flow monitoring units and adjusts the water consumption mode of the water heater according to the position information.
