FIG. 4 is a circuit diagram of the telecontrol controller 40. In the figure, reference numeral 50 denotes a control circuit such as a microcomputer. The control circuit 50 is connected to a tele-con switch 3i, a call setting key 3j and a password setting switch 3k of the operation panel 3. Reference numeral 52 denotes a normally-open first relay which is an example of a connection unit; 53, a normally-closed second relay which is an example of a disconnecting unit; 54, a voltage detection circuit such as a comparator which is an example of a detection unit; Is D
Extracting only the AC component on which the TMF signal is
This is a transformer for superimposing an audio signal on L ₁ -L ₂ . The control circuit 50 has a function of connecting the line when the number of calls reaches the number set by the call setting key 3j, and responds by voice when the password set by the password setting switch 3k is input from an outside line. A first relay 52, a second relay 53, a function of detecting whether or not a line of another device 100 is connected by an input signal of a V _IN terminal.
And the like. The voltage detection circuit 54
Detects the voltage V _r between the L ₁ -L _2, it is intended to enter the output to V _IN terminal of the control circuit 50, another telecontrol device 100 connected to the T ₁ -T ₂ is connected on the line And the voltage _Vr drops to a predetermined value,
00 can be detected.

When another device 100 is not connected to terminals T ₁ and T ₂ , or when another device 100 is connected and the number of calls of fully automatic rice cooker 1 is set smaller than the number of calls of another device 100, When a phone call from the outside is applied, and the oN switch S ₁ of the first relay 52 when the call number set by the call setup key 3j is made, a state in which all only automatic rice cooker 1 is led over the line . Here, the control circuit 50 responds by voice from LINE1 to LINE2, and when a password set in advance by the password setting switch 3k is input from an external telephone, the telecontrol can be performed, and thereafter, rice cooking and time reservation can be performed. And other predetermined operations. Thus, various commands can be given to the fully automatic rice cooker in an interactive manner.

In a state where the fully automatic rice cooker 1 and the separate device 100 are both connected to a telephone line, the fully automatic rice cooker 1
Is set to be greater than the number of calls of another device 100, when a call is made from the outside, the other device 100 is first connected on the line. Then, the voltage V _r between the L ₁ -L ₂ was 48v until it drops to about 6～10V, which is detected by the voltage detection circuit 54 outputs a LOW level to V _IN of the control circuit 50. That is, when the input of V _IN changes from HI to LOW, it is possible to detect that another device 100 is connected on the line. When the input of V _IN is changed to LOW from HI, the control circuit 50 is turned ON the switch S ₁ of the first relay 52, full automatic rice cooker 1 is also a state of connecting the fixed time line. If you enter a number that matches the configured PIN previously fully automatic rice cooker 1 from an external phone within this time, the switch S ₂ of the second relay 53 is O
FF, and off of T ₁ side is connected to another device 100 line. As a result, the separate device 100 is disconnected from the line, and only the fully automatic rice cooker 1 can be controlled from the outside. Thereafter, the fully automatic rice cooker 1 can be telecontrol-controlled interactively as described above. On the other hand, in a state where both devices 1 and 100 are connected on a line, if a password corresponding to another device 100 is input from an external telephone,
There it can be controlled, fully automatic rice cooker 1 retains the state a certain time line is connected, then OFF switch S ₁ of the first relay 52 together with a time-up eventually break themselves line. In this manner, either the fully automatic rice cooker 1 or the separate device 100 can be selectively tele-controlled.

Here, specific telecontrol control of the fully automatic rice cooker 1 will be described with reference to FIGS.
When a call is made from outside, it is first determined whether a specified number of calls have been made (step 60). This determination is made based on whether or not the number of calls reaches the number set in advance by the call setting key 3j. Until call count reaches the specified number of times, L ₁ -L voltage V _r between ₂ t seconds 5-20
It is determined whether or not it is within the range of v (step 61). If it is not within this range, it waits for the number of calls. When another device 100 is not connected to the T terminal, or when another device 100
Is connected and the number of calls of the fully automatic rice cooker 1 is
When set from the invocation count small, since always calls the specified number is made, the switch S ₁ of the first relay 52
Is turned on (step 62), and only the fully automatic rice cooker 1 is connected on the line. Here, the control circuit 50 responds with a voice message “Please enter your password” (step 6
3). Then, when a number and a "#" key are input from an external telephone (step 64), it is determined whether or not this number matches a password preset by the password setting switch 3k (step 65). . If not match, repeat the same operation returns to step 63 again, if performed incorrectly entered three times (step 66), the switch S ₁ of the first relay 52 is cut off the line and OFF ( Step 67), end. If the passwords match, the voice responds, "Please specify the operation" (step 68), and inputs a predetermined number and the "#" key (step 69).

On the other hand, when the fully automatic rice cooker 1 and the separate device 100 are both connected to the telephone line and the number of calls of the fully automatic rice cooker 1 is set to be larger than the number of calls of the other device 100, the number of calls is reduced. because another device 100 is connected on the line before the specified number of times, the voltage V _r becomes in the range of 5～20V, switch S ₁ of the first relay 52 is oN (step 70). That is, both the fully automatic rice cooker 1 and the separate device 100 are connected to the line. Here, as in step 64, when a number and a "#" key are input from an external telephone (step 72), it is determined whether or not this number matches the password of the fully automatic rice cooker 1 (step 73). ).
If not match, repeat the same operation again returns to step 72, performs time waits for a predetermined time t ₀ (step 74). If there is no input of the password of the fully automatic rice cooker 1 during the time t ₀ , the switch S ₁ of the first relay 52 is turned off to disconnect the line (step 75), and the process is terminated. Remains connected to the line,
After that, it is left to the control of the separate device 100. When the full automatic rice cooker 1 PIN number is entered in step 73, the switches S ₂ of the second relay 53 is turned OFF to disconnect the another device 100 from the line (step 76), the process proceeds to step 68 described above.

If "0 #" is entered in step 69 (step 77), "hang up the telephone" is displayed as shown in FIG.
And voice response (step 78), cut off the line and OFF the switch S ₁ of the first relay 52 (step 79),
finish. If "1 #" is entered, the mode is the cancellation mode (step 80), and a voice response is given (step 81), and the process returns to step 68. When "2 #" is entered, the operation state confirmation mode is set (step 82). For example, "the current state is being kept warm" or "the cooking is reserved for xx hours and xx minutes."
And the voice responds (step 83), and returns to before step 68. When "3 #" is input, the rice cooking mode is set (step 84), and a voice responds "Please set the amount of rice" (step 85). Here, an arbitrary number from 1 to 9 and a "#" key are displayed. Is input (step 86), the voice responds to "Please set the cooking time" (step 87), and in response to this, input OO hour XX minutes and the "#" key (step 88). ), Return before step 68. In addition, when cooking rice is started immediately, "9999
# ".

When an erroneous key operation is performed,
The operation returns to step 68 with a voice response of "operation not accepted", and if there is no key operation, the line is disconnected after a certain period of time.

In the above-described telecontrol control, the manual mode and the telecon mode are switched by the manual switch 3i. However, the mode may be switched from a telephone set outside.

In the above embodiment, the telecontrol control of the fully automatic rice cooker 1 has been described, but it goes without saying that the present invention can be applied to any telecontrol equipment. Further, the connection method is not limited to a method in which the present device 1 and another device 100 are vertically connected to a telephone line as shown in FIG. 3, but two devices 2 having the same functions as the present invention as shown in FIG.
A normal telephone 202 may be connected vertically after 00 and 201.
