In Fig. 11, S stands for step STEP.

As an initial condition of the method for controlling the electric bed by telephone, it is assumed that telephone line 124 is connected to telephone line terminal 18 shown in Fig. 5 by telephone line.

First, in the telephone control signal input determination step S21, the first control means 102 determines whether a telephone control signal has been input from the telephone signal transmission / reception circuit 122. As a result of this determination, when it is determined that the telephone control signal is input from the telephone signal transmitting and receiving circuit 122, the flow proceeds to the key reading step S22 (if YES).

For reference, a process in which a user calls his home from outside of his home and inputs a telephone control signal for temperature control of the surface of the mat 4 to the first control means 102 will be described below. same.

The user dials his home from outside of his home.

The next time the call is received by an answering machine, the user enters a control command for temperature control of the bed, using the displayed letters (*, #) and number on the other telephone in front of him. Then, the control command is transmitted to the first control means 102 via a path of a telephone in front of a user → an external communication station 130 → a telephone 124 of a user's home → a telephone line terminal 18 → a telephone signal transmission / reception circuit 122. ) Is entered.

Next, in the key code reading step S22, the first control means 102 reads the key code of the control command input to the first control means 102. Next, as shown in FIG.

Next, a control signal is output from the first control means 102 to the first heater drive circuit 106, the second heater drive circuit 110, and the magnetic field generation coil 116 in the load driving step S23. Then, the first heater 108, the second heater 112, and the magnetic field generating coil 116 from the first heater driving circuit 106, the second heater driving circuit 110, and the magnetic field generating coil 116. The voltage is applied to each. Next, the first heater 108, the second heater 110, and the magnetic field generating coil 116 are operated as the user intends.

Next, in the voice guidance step S24, voice is output from the first control means 102 to the telephone signal transmission / reception circuit 122. Then, voice is transmitted from the telephone signal transmission / reception circuit 122 to the telephone in front of the user via the telephone line terminal 18 → the telephone 124 in the user's home → the external communication station 130. Then, the user hears the voice output from the telephone receiver of the telephone in front of him, and the current temperature of the mat 4, the set temperature, the first heater 106, the second heater 110 and the magnetic field generating coil 116 Know the operating status.

On the other hand, when the first control means 102 determines that no telephone control signal is input from the telephone signal transmission / reception circuit 122 in the telephone control signal input determination step S21 (if NO), the telephone control signal In an input discrimination step S21, the first control means 102 waits for a telephone control signal to be input from the telephone signal transmission / reception circuit 122.

As described above, according to the electric bed according to the present invention, the operation panel is separated from the headboard to decorate one side of the housing and installed inside the headboard has a very excellent effect to protect the user from electromagnetic waves.

In addition, when the user operates the bed by a telephone from the outside, there is a very excellent effect that the user can check the operation state of the bed by voice.

In addition, bidirectional communication is performed between the reamer controller and the first control means in the housing, and thus the user can check the operation state of the electric bed through the display means provided in the remote controller.

On the other hand, according to the control method of the electric bed according to the present invention, when the user operates the bed by a telephone from the outside, the user can check the operation state of the electric bed by the voice output from the telephone in front of his own It works.
