Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For convenience of description, the present embodiment will be described in detail by taking a washing machine as an example. It is easily understood by those skilled in the art that the water using device of the present invention is not limited to a washing machine, but is also applicable to other water using devices, such as a dishwasher, etc.
Since existing domestic water heaters generally require multiple point water-using equipment to be supplied for use, different usage scenarios place different demands on the water heater. For example, when a user needs to use the washing machine, other users are bathing with the water heater. However, the water temperature used for bathing is often inconsistent with the required water temperature of the washing machine. Thus, there are two problems:
on the one hand, if the current bath water temperature is higher than the required water temperature of the washing machine, if the washing machine is supplied in accordance with the bath water temperature, the laundry inside the washing machine may be damaged due to the high temperature; and if the water temperature output by the water heater is adjusted according to the water temperature required by the washing machine, the bath water temperature is reduced, and the user experience is poor.
On the other hand, if the current bath water temperature is lower than the required water temperature of the washing machine, if the washing machine is supplied with the bath water temperature, the laundry in the washing machine may not be washed clean due to the low temperature; if the water temperature output by the water heater is adjusted according to the water temperature required by the washing machine, the temperature of the bath water can be increased, and the risk of scalding a user is caused.
In order to avoid the problems, the intelligent hot water washing machine realizes the purpose of intelligent hot water washing through cooperatively controlling the water heater and the washing machine. The specific process of the present invention is described in detail below.
As shown in fig. 1, the intelligent hot water washing method of the present invention includes the following steps: s110, acquiring required temperature setting information of the washing machine; s120, acquiring the running state of the water heater; and S130, controlling the operation of the washing machine and/or the water heater according to the required temperature setting information of the washing machine and the operation state of the water heater.
In the above step S110, the demand temperature setting information may include whether the demand temperature is set or not, a specific temperature value set in the case where the demand temperature is set, and the like. The demand temperature setting information can be determined in a direct or indirect manner. Specifically, in the case where the required temperature has been set, the user may directly input the required temperature of the washing machine while using the washing machine, and then the required temperature is transmitted to the server. Or when the user uses the washing machine to wash, other washing information (such as washing mode, type of clothes to be washed, etc.) of the washing machine may be input, and the control module (the first control module in the claims) indirectly determines (such as calculates or deduces) the required temperature of the washing machine according to the washing information, and transmits the required temperature to the server. In addition, the invention is applicable to any other reasonable mode capable of obtaining the set required temperature of the washing machine.
In the step S120, the operation state of the water heater may include: shutdown state, standby state, fault state, occupied state, etc. The operating state of the water heater can be obtained in any suitable manner according to the setting position of the server, and the detailed description is omitted here.
The control strategy of step S130 is explained in detail below with reference to fig. 2A and 2B. Fig. 2A is a detailed flow chart of the main washing water inlet stage of the washing machine according to the first embodiment of the present invention. Fig. 2B is a detailed flowchart of the rinsing water inlet stage of the washing machine according to the first embodiment of the present invention.
As shown in fig. 2A, in the main washing stage, after the washing machine is turned on, a washing machine program is set and the washing machine is started. At this time, the required temperature setting information of the washing machine and the operation state of the water heater may be acquired through the server. Judging whether the washing machine sets the required temperature or not according to the required temperature setting information of the washing machine, and acquiring the required temperature value of the washing machine under the condition that the washing machine sets the required temperature.
In case the washing machine has set the required temperature:
when the water heater is shut down, the server controls the water heater to be started, sets the output temperature of the water heater to be the required temperature, then controls a water inlet valve of the washing machine to be opened, and the washing machine starts to feed water.
When the water heater is in standby, the server sets the output temperature of the water heater to be the required temperature, then controls the water inlet valve of the washing machine to be opened, and the washing machine starts to feed water.
When the water heater is in a fault or occupied state, the server can send prompt information to the washing machine or the operation terminal, and a user selects whether to delay water inflow of the washing machine or not according to the prompt information. When the user selects not to delay water inlet or does not make a selection within the preset time, the server does not change the running state of the water heater and directly controls the water inlet of the washing machine; when the user selects the delayed water inlet, the server controls the washing machine to suspend water inlet until the water heater is in a standby state, corresponding operation is executed, namely the server sets the output temperature of the water heater to be the required temperature, and the washing machine starts water inlet. If the water inlet valve of the washing machine is controlled to be opened, the washing machine starts to feed water.
In case the washing machine does not set the required temperature:
when the water heater is shut down, the server does not change the running state of the water heater, then the water inlet valve of the washing machine is controlled to be opened, and the washing machine starts to feed water.
When the water heater is in a standby state, the server controls the water heater to be turned off, and the washing machine starts to feed water in the state that the water heater is turned off. If the water inlet valve of the washing machine is controlled to be opened, the washing machine starts to feed water.
When the water heater is in a fault or occupied state, the server can send prompt information to the washing machine or the operation terminal, and a user selects whether to delay water inflow of the washing machine or not according to the prompt information. When the user selects not to delay water inlet or does not make a selection within the preset time, the server does not change the running state of the water heater and directly controls the water inlet of the washing machine; when the user selects the delayed water inlet, the server controls the washing machine to suspend water inlet until the water heater is in a standby state, corresponding operation is executed, namely the server controls the water heater to be shut down, and the washing machine starts water inlet under the state that the water heater is shut down. If the water inlet valve of the washing machine is controlled to be opened, the washing machine starts to feed water.
It should be noted that, when the water heater fails, it indicates that the water heater may not heat or may not heat normally, and at this time, if the washing machine is not selected to be fed with water in a delayed manner, the water output by the water heater in the current failure state is directly sent to the washing machine. When the water heater is occupied, it is said that the water heater is in use, and may be used for bathing, washing hands, etc. At this time, in order to avoid the risk caused by the water temperature difference, the user is prompted to select whether to delay water inflow of the washing machine.
The washing machine performs dewatering after the main washing, and enters a rinsing water inlet stage after the dewatering. In order to improve the washing effect of the washing powder, a water heater is required to supply water with a proper temperature to the washing machine in the main washing stage. And only normal temperature water is needed to rinse in the rinsing stage.
As shown in fig. 2B, during the rinse water inlet phase, the server still needs to obtain the operation status of the water heater. The water inlet stage does not set the required temperature of the washing machine. The control strategy is similar to the situation described above where the demand temperature is not set. Specifically, the method comprises the following steps:
when the water heater is shut down, the server does not change the running state of the water heater, and the washing machine starts to feed water. For example, the water inlet valve of the washing machine is controlled to be opened, and the washing machine starts to feed water.
When the water heater is in a standby state, the server controls the water heater to be shut down, and the washing machine starts to feed water when the water heater is shut down. If the water inlet valve of the washing machine is controlled to be opened, the washing machine starts to feed water.
When the water heater is in a fault or occupied state, the server can send prompt information to the washing machine or the operation terminal, and a user selects whether to delay water inflow of the washing machine or not according to the prompt information. When the user selects not to delay water inlet or does not make a selection within the preset time, the server does not change the running state of the water heater and directly controls the water inlet of the washing machine; when the user selects the delayed water inlet, the server controls the washing machine to suspend water inlet until the water heater is in a standby state, corresponding operation is executed, namely the server controls the water heater to be shut down, and the washing machine starts water inlet under the condition that the water heater is shut down. If the water inlet valve of the washing machine is controlled to be opened, the washing machine starts to feed water.
And after the whole washing cycle is finished, the server controls the water heater to be powered off or to be restored to the water heater setting before washing.
Referring to fig. 3A and 3B as another embodiment of the present invention, fig. 3A is a detailed flowchart of a main wash water inlet stage of a washing machine according to a second embodiment of the present invention; fig. 3B is a detailed flowchart of the rinsing water inlet stage of the washing machine according to the second embodiment of the present invention.
As shown in fig. 3A and 3B, in the main washing water inlet stage and the rinsing water inlet stage of the washing machine, when the water heater is in an occupied state, at this time, in order to avoid affecting users during the use of the washing machine, and preferably meet the use requirements of the users, the server directly sends a delayed water inlet instruction to the washing machine, so that the water inlet of the washing machine is suspended. And the server acquires the running state of the water heater according to a preset interval (such as 1 minute), and when the water heater is in an unoccupied state, the server continuously judges the running state of the water heater and carries out the next operation. Reference may be made to the above-mentioned implementation one, which is not described herein again. In addition, in the embodiment, when the water heater fails, the water inlet of the washing machine can be directly controlled without changing the running state of the water heater. So that the whole control strategy does not need to send prompt information to the user.
It should be noted that the instruction of "the server sends the prompt message to prompt the user whether to select the washing machine to intake water in a delayed manner" may be to remind the user each time, and then the user selects the instruction, or may be to set the program in advance (which may be set automatically or manually by the washing machine, the server, the operation terminal, etc.), and then when the prompt message appears, the program is selected automatically. For example, after the program of automatic delay is set in advance, when the washing machine conflicts with other equipment (when the washing machine and other equipment use the water heater at the same time), the program automatically controls the washing machine to suspend water inflow and continue water inflow after no other water is available; when the user sets in advance that water is not delayed to enter, the washing machine does not need to pause water inlet but does not change the temperature setting of the water heater when the water inlet conflict stage is reached, and hot water currently output by the water heater is directly used. When the washing machine is operated to other stages, such as washing, dewatering, rinsing and other stages without water inflow, in order to ensure other water consumption (such as bathing) of a user, the server controls the parameter setting of the water heater to be restored to the parameter setting before washing, and the use of the water heater by the user is ensured not to be influenced.
In the preferred embodiment of the above method, the water using device is not limited to a washing machine, but may be other water using devices such as a dishwasher, and the water heater is preferably a gas water heater, but may be other types of water heaters, such as an electric water heater.
Correspondingly, the invention further provides a cooperative control system of the washing machine and the water heater. As shown in fig. 4, the system includes a washing machine, a water heater and a server, the washing machine is communicated with the water heater, and the server can obtain the required temperature setting information of the washing machine and the operation state of the water heater, and control the operation of the washing machine and/or the water heater according to the required temperature setting information of the washing machine and the operation state of the water heater.
Preferably, the system further comprises a first control module and a second control module. The first control module can be arranged on the washing machine and can also be arranged on an operation terminal such as a mobile phone and a tablet, and the server acquires the required temperature setting information of the washing machine through the first control module and controls the water inlet state of the washing machine. The second control module can be arranged on the water heater and can also be arranged on an operation terminal such as a mobile phone and a tablet, and the server can acquire the running state of the water heater through the second control module and control the water outlet state of the water heater. It should be noted that the operation terminal in the present invention is any terminal other than the washing machine and the water heater, for example, the operation terminal may be a mobile terminal such as a mobile phone and a tablet, or may be other fixed terminals, for example, an intelligent operation panel installed on a wall surface or other fixed positions. The operation terminal may be fixed at a plurality of positions in a dispersed manner, or may be integrated.
Preferably, the first control module determines the required temperature setting information of the water using equipment in a direct or indirect mode and transmits the required temperature setting information to the server. Specifically, when the user uses the washing machine, the required temperature of the washing machine can be directly input and then transmitted to the server by the first control module; or when the user uses the washing machine to wash, other washing information (such as the type of the washed clothes) of the washing machine is input, the first control module calculates the required temperature of the washing machine according to the washing information, and the required temperature is transmitted to the server.
The control strategy of the system can be referred to above, and is not described in detail herein. In addition, the server in the system can be a cloud virtual server or a near-end physical server, and as a physical server, the server can be arranged at a washing machine end, a water heater end, a background or an operation terminal. These positional changes are formal adjustments and do not affect the basic principle and the scope of protection of the present invention. The water using equipment of the invention is not limited to washing machines, and can also be other water using equipment such as dish washing machines and the like.
In conclusion, the water consumption equipment and the water heater are coordinately controlled, so that the problem that a plurality of water consumption equipment conflict when the water heater is used is solved while the water consumption equipment uses hot water. Taking a washing machine as an example, by the coordination control of the washing machine and the water heater, the problems that the pulsator washing machine cannot heat and the drum washing machine heats slowly are avoided on one hand, so that the washing time is shortened while the clothes are cleaned. On the other hand, when the water heater is used for supplying water for the washing machine, the control strategy is adopted to adjust the water inlet of the washing machine according to the running state of the water heater and the required temperature information of the washing machine, so that the problems that when a user runs the washing machine while using the water heater (such as bathing), the water outlet temperature of the water heater is suddenly high and suddenly low due to different washing temperatures of the bathing machine and the washing machine, the bathing experience is influenced (such as the temperature is too high and the risk of scalding), clothes cannot be washed cleanly, clothes are damaged due to the overhigh temperature, and the like are solved. The technical scheme of the invention greatly improves the use experience of the user.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
