Therefore, it is obvious that the control method of the home appliance automatic control method of the present invention described below is only one embodiment, and the control contents are not limited thereto.

Referring to FIG. 2, control contents according to an embodiment will be described below.

Each home appliance detects the necessity of controlling the home appliances when performing its function. This aspect of the need for control can vary depending on each appliance.

First, it may be a control method of judging the necessity of control between home appliances when the sum of consumed electric power consumed by each appliance is equal to or greater than a predetermined total electric power consumption, and lowering at least one of the consumed electric power. For example, it is possible to adjust the power consumption by grasping the usage situation among the home appliances. This power consumption adjustment may be a setting to adjust the peak power between the home appliances and to prevent the breaker from operating to cut off electricity.

Secondly, it is necessary to judge the necessity of control of the home appliances when the distance between one home appliance and the other home appliances is at a preset reference distance, to turn on / off the power of the other home appliances, Lt; / RTI > For example, when the room is cleaned by the cleaner 7, for example, when the living room is cleaned and then the room is cleaned, the lighting device 6 is automatically , And can be automatically set to OFF when leaving the room. Further, when the vacuum cleaner 7 is in close proximity, the volume of the television 9 may be automatically controlled.

Third, it may be a control method of determining necessity of control of another home appliance when the one home appliance reaches a preset remaining time during operation, turning on / off the power of the other home appliance, or adjusting the volume. For example, when performing the washing and dewatering steps using the washing machine 2, it is possible to set a control such that the heater or the like of the dryer 3 is automatically turned on just before the end of washing.

Fourth, when the temperature detected during operation of each of the home appliances is equal to or higher than a predetermined temperature, it may be a control method of determining necessity of controlling the home appliances mutually and lowering at least any one of the power consumption. For example, it is possible to automatically adjust the cooling / heating intensity of the air-conditioner / air-conditioner 8 during the operation of the home appliance with a large heat dissipation or to control the power consumption of other home appliances to be lowered.

Another specific embodiment according to the present invention is shown in Fig.

3 is a view schematically showing another embodiment of a method for automatically controlling a home electric appliance according to the present invention.

Specifically, referring to Fig. 3, a specific example of control between the washing machine 2 and the bath pump 11 is shown. The washing machine (2) can control the bath pump (11) by wireless communication. The water supply hose 12 is provided to communicate with the water supply channel of the washing machine 2 to supply water to the bathtub 13 and the bath pump 11 is provided at one side of the water supply hose 12.

When the user connects the power source of the bathtub pump 11, the user can control the washing machine 2 to display the operation menu of the bathtub pump on the display unit 120 of the washing machine 2. In this case, the on / off control of the bath pump 11 can be easily performed, and the water temperature and water amount in the bathtub 13 can be more easily adjusted. Conversely, when water supply is interrupted, water can be supplied to the washing machine 2 by the bath pump 11 to use the water received in the bathtub 13 as washing water.

Further, mutual control by wireless, not wired, is advantageous in that the waterproofing treatment of wiring is unnecessary, and the problem of disconnection, connection error, and poor contact between connectors can be solved.

That is, the present invention can realize an automatic control method of household appliances that can grasp the mutual operation state of the home appliances and provide more convenience to the user.

Hereinafter, the method for automatically controlling the electronic appliances of the present invention will be described in detail as follows.

An automatic control method between home appliances according to an embodiment of the present invention includes a device authentication step for performing communication for registering appliances between home appliances, and a communication for control when there is a necessity of home appliances mutual control And a device control step of controlling the device.

The main technical features of the present invention are the communication method for device authentication or device control, and the control method implemented in the device control step as described above can be variously set.

First of all, in order to perform mutual control between home appliances, it is necessary to register (authenticate) between appliances at an early stage.

4 shows a communication flow chart at the time of initial registration between home appliances according to an embodiment of the present invention.

Referring to FIG. 4, in the communication step between the mutual apparatus registration procedure communication methods, the household appliances to be used first confirm whether there are household appliances which can communicate with each other around (S100).

Thereafter, when there is a device capable of communicating, it is checked whether the device is registered between the mutual home appliances (S110).

Thereafter, when the mutual household appliances are in an unregistered state, a registerable appliance is displayed on a display unit provided in each home appliance (S120).

After that, the request for approval of the device that can be registered is requested. If the request for approval is made, the data is stored in the memory (S130).

However, if there is no device capable of communicating in S100, the device is registered in S110, the device is not registerable in S120, or if there is no approval for the S130 approval request, the mutual communication can be terminated have.

Here, the step S130, that is, the mutual approval method between the devices, can be specified as follows.

FIG. 5 is a flow chart illustrating a communication method for registration between home appliances according to FIG. 4, and FIG. 6 is a diagram showing data communicated when registering home appliances according to FIG.

If a registerable household appliance is selected after the step S120, the registration operation device transmits data asking whether to register the appliance for the appliance approval procedure (S131, S132).

Thereafter, the to-be-registered operation device returns the reply data after receiving the data asking whether or not to register (S133, S134).

After that, the registration operation device displays the information of the registration operation device on its display unit (S135). If the registration operation device does not register the communication, the communication operation is terminated. When the registration operation device is registered, the replay reply data is transmitted to the registration operation device (S136, S137).

Thereafter, the to-be-registered operation device displays the received re-reply data on its display unit, and then transmits the registration failure code that is generated when the authentication is impossible or the authentication failure data including the registration establishment code that is generated when the authentication is possible. And returns it to the device (S138, S139).

In this case, referring to FIG. 6, the detailed contents of the data communicated in each step will be described below.

In S131 and S132, the data for inquiring about registration may include a start signal, a dedicated sync code for requesting registration, and an end signal.

On the other hand, in S133 and S134, the reply data includes a start signal, a sync code dedicated to the registered data reply, an own code thereof, an authentication code separately generated each time the device-to-device registration is performed, a controllable code, .

On the other hand, in S136 and S137, the re-reply data may include a start signal, a registration-dedicated sink code, own unique code, an authentication code received from the registered operation device, and an end signal.

On the other hand, in S138 and S139, the authentication data may include a start signal, a reply-only sink code, a result code composed of its own unique code, a registration non-establishment code or a registration establishment code, and an end signal.

Initial registration between home appliances for implementing the present invention can be performed by the above-described concrete method, and a communication method for controlling between home appliances will be described below.

7 is a flowchart showing a control flow chart between home electric appliances according to an embodiment of the present invention.

Specifically, referring to FIG. 7, the control communication method in the communication step first confirms necessity of controlling the controlled device during operation of the control device (S200).

If there is a necessity of control, communication is attempted with the controlled device (S210). If communication is established, control data is transmitted to the controlled device (S220).

Thereafter, if the controlled device recognizes the control data (S230), the controlled device is automatically controlled according to the contents of the control data (S240).

However, if it is determined in S200 that there is no need to control the controlled device, it is desirable to reaffirm the necessity of control at predetermined intervals.

If it is determined in step S210 that the control device and the controlled device do not communicate with each other, it is preferable to retry communication for a predetermined number of times and to terminate the communication for control if the communication fails.

Meanwhile, S220 and S230, that is, the control communication method, may be specified as follows.

FIG. 8 is a flowchart showing a communication method for controlling according to FIG. 6, and FIG. 9 is a diagram showing data to be mutually communicated when controlling between home appliances according to FIG.

After S210, if the home appliances communicate with each other, control data is transmitted to the controlled device (S200).

Thereafter, the controlled device receives the control data (S231), confirms whether the authentication code generated at the time of mutual registration is matched (S232), performs control according to the control data when the authentication code is matched (S233 ), And returns the acknowledgment data to the control device (S234).

Thereafter, the removal device receiving the acknowledgment data displays control contents of the controlled device on the display unit (S235).

 If the controlled device can not recognize the received control data in S231 or if the authentication code is inconsistent in S232, it is preferable that an error code is generated and transmitted to the control device.

In this case, the detailed contents of the data will be described with reference to FIG.

In S200, the control data may include a start signal, a control transmission exclusive sync code, own unique code, an authentication code stored in a memory at the time of registration, a control code, and an end signal.

On the other hand, in S234, the acknowledgment data may include a start signal, a sink code dedicated for control reply, a result code composed of its own unique code, a control performed or an error code, and an end signal.

With this communication method, the initial registration communication and the control communication are performed between the home appliances, and the present invention can implement the automatic control between the home appliances without any user's operation.
