17 are provided. Further, the remote control device 11 has a remote control device side operation unit 18 composed of a plurality of buttons and the like on an upper surface, and has a light emitting unit 19 on one end surface which constitutes a transmission unit for transmitting a radio signal. ing.

Further, in FIG. 1, reference numeral 21 denotes a cover laid on the carpet body 1, and the cover 21 may cover the controller unit 4 from above. Reference numeral 22 denotes a reflection sheet that reflects a radio signal composed of the infrared rays or the like. The reflection sheet 22 can be attached to an appropriate surface such as a wall surface in a room.

Next, a functional configuration of the control unit and the remote control device 11 provided in the controller unit 4 will be described with reference to FIG. The control unit 31 controls various operations including energization of the heater 2, and includes a processing unit 32 including a microcomputer or the like. Is controlled. The control section 31 is operated by the main body side operation section 15. Further, the control unit 31 includes the remote control device mounting unit.

In the operation by the main body side operation unit 15, a power on / off operation, a temperature adjustment operation, a heating area switching operation, a timer operation, a reservation operation, and the like can be performed. In the remote control device side operation unit 18, power on / off operation, temperature adjustment operation, heating area switching operation,
Timer operation, reservation operation, etc. can be performed. When the reservation operation is performed, the processing unit 32 of the control unit 31 sends the remote control device to the remote control device mounting unit 18.
When 11 is mounted Remote control device side operation unit
It has a function as a reservation means for executing the instruction by (18). At the same time, the control unit 31 is configured to accept a command from the operation of the main body operation unit 15 only when the remote control device mounting unit 18 does not have the remote control device 11. Further, the reflection sheet 22 reflects a wireless signal transmitted from the remote control device 11 toward the control unit 31.

Further, the controller unit 4 has a built-in printed wiring board 41 on which components constituting the control unit 31 are mounted. As shown in FIG. And a lead wire 42 for wiring in the printed wiring board are connected by a connection terminal 43. Next,
The configuration of the connection terminal 43 will be described. 44 is a heating wire of the main body of the heater 2, and 45 is a winding in the wire. The connection terminal 43 relays between a switching element such as a relay for controlling on / off of a load current, that is, a current flowing through the heater 2, and a heating wire 44 of the heater 2, and an insertion portion inserted into the printed wiring board 41. 46 and a lead wire connection part 47 to which the lead wire 42 for wiring in the printed wiring board is connected
And a wire connection portion 48 to which the wire winding 45 of the heater 2 is connected.

Since a load current of, for example, about 4 A flows through the heating wire 44, a problem such as heat generation due to a large current may occur at the connection portion. In order to suppress this, the lead wire 42 is directly connected to the connection terminal 43 as described above so that the load current does not flow through the pattern of the printed wiring board 41.

Next, the operation of the above configuration will be described. In this electric carpet, the operation of the control unit 31 in the carpet main body 1 can be performed by both the main body side operation unit 15 and the remote control device side operation unit 18. In particular, when operated with the remote control device side operation unit 18, a radio signal is transmitted from the light emitting unit 19 of the remote control device 11 in accordance with this operation, and this signal is transmitted to the light receiving unit 17 of the controller unit 4 of the carpet body 1 side. The controller 31 controls ON / OFF of the heater 2 according to the received signal. Then, as long as the signal from the remote control device 11 is within a range where the signal reaches the controller unit 4, the remote control device 11 can be operated at an arbitrary place.

Further, for example, when the cover 21 is placed on the controller unit 4 and the radio signal transmitted from the remote control device 11 is blocked by the cover 21 on the straight path, the radio signal is stuck on the wall surface of the room. The wireless signal can be received by the light receiving section 16 of the controller unit 4 by reflecting the light on the attached reflecting sheet 22. For this purpose, it is preferable to attach the reflection sheet 22 to a position facing the light receiving unit 16 exposed below the cover 21 on a wall surface of a room or the like. Then, when a signal is transmitted from the remote control device 11 to the reflection sheet 22, the signal is reflected by the reflection sheet 22 and received by the light receiving unit 16.

As described above, according to the configuration of the embodiment, the operation of the electric carpet can be performed on both the carpet body 1 and the remote control device 11, and the operability is improved. In particular, when the remote control device 11 is used, the operation can be performed at any place, and the usability is good. That is, the operation can be easily performed without having to stand up or move from the place where the person who is going to operate is present. This is also desirable in an aging society.

Further, in the present electric carpet, a reservation operation using the remote control device 11 is also possible. In the case of a reservation operation, even if another operation is performed after the reservation state is set by a predetermined operation, the control unit 31 does not immediately execute the instruction corresponding to this operation. Thereafter, when the remote control device 11 is mounted on the remote control device mounting portion 12 of the carpet body 1, the light sensor 34 detects that the remote control device 11 has been mounted, so that the operation with the remote control device 11 can be performed. The corresponding command is received and executed by control unit 31.

On the other hand, the remote control device mounting section 18
In the state where the remote control device 11 is attached to the device, the operation by the main body side operation unit 15 is not accepted. In particular, in the present embodiment, since the remote control device 11 covers and hides the main body side operation unit 15 from above, the operation itself of the main body side operation unit 15 cannot be performed. That is, when the remote control device 11 is mounted on the remote control device mounting portion 12, the control portion 31 is operated by the remote control device side operation portion. On the other hand, when the remote control device 11 is detached from the remote control device mounting portion 12, the control operation can be performed by the remote control device side operation portion 18 or the main body side operation portion 15 as described above.

The remote control device mounting section 18
The operability is further improved by providing a reservation unit for causing the control unit 31 to execute a command from the remote control device-side operation unit 18 when the remote control device 11 is mounted on the control unit 31.

Further, if the reflection sheet 22 is used, the light receiving section
Even if the cover 21 is hung on the controller unit 4 with 17, the operation by the remote control device 11 can be performed without turning up the cover 21,
Operability is further improved.

By the way, the heating wire 44 of the above embodiment is used.
Connection terminals 43 for relaying the wiring leads 42 in the printed wiring board are the same as those conventionally used, but the conventional connection terminals 43 are substantially orthogonal to the printed wiring board 41. The two pieces have the same direction, and are connected to the lead wire connection part 47 of one piece by means such as soldering or spot welding, and the wire connection part of the other piece is provided.
48 is connected by means such as caulking.
Then, at the time of connection, after the lead wire 42 is connected to the connection terminal 43 in advance, the insertion portion of the connection terminal 43 is inserted into the printed wiring board 41, and is flowed simultaneously with other general electronic components into the flow solder tank to perform automatic soldering. The connection terminal 43 is mechanically fixed to the printed wiring board 41.

However, in this conventional method, pre-processing such as entanglement, soldering, or spot welding of the lead wire 42 to the connection terminal 43 before automatic soldering of general electronic components is performed. It was necessary and required a lot of man-hours.

Is slightly projected from the back surface. Then, on the solder surface of the printed wiring board 41, the connection portion through hole 57
It is open to. Further, copper foil lands are provided around the connection portion through holes 57 on the solder surface of the printed wiring board 41.

Then, in the assembly process of the control circuit constituted by the printed wiring board 41, the assembly around the connection terminal 51 is performed as follows. First, the cylindrical portion 55 and the locking claw portion 56 of the connection terminal 51 are inserted into the connection portion through hole 57 and the claw portion through hole 58 of the printed wiring board 41, and the connection terminal 51 is inserted into the printed wiring board 41.
After that, the lead 42 for wiring in the printed wiring board from an opening / closing element such as a relay is inserted into the tubular portion 55. Next, the printed wiring board 41 on which these electronic components are mounted is flowed into a flow solder bath to perform automatic soldering.

As a result, the lead wire for wiring in the printed wiring board
The core wire 42 has a cylindrical portion formed by solder 59 that has risen inside a cylindrical portion 55 that is an eyelet portion reaching the solder surface of the printed wiring board 41.
55 and thus the connection terminal 51 is electrically and mechanically connected. In addition, a cylindrical part is formed on the solder surface of the printed wiring board 41.
Since there is a land around 55, solder 59 is attached, and the cylindrical part 55
Is fixed to the printed wiring board 41.

As described above, according to the configuration of the second embodiment, the connecting terminal 51 is provided with the cylindrical portion 55 which is the eyelet-shaped lead wire connecting portion penetrating the solder surface of the printed wiring board 41. Therefore, the lead wire 42 from the switching element can be connected by automatic soldering, and the work of connecting the lead wire 42 and the connection terminal 51 in advance becomes unnecessary. Therefore, the efficiency of the assembly operation can be improved. Conventionally, lead wire 42 and connection terminal
The work prior to connection with 43 was performed manually, but since this is no longer necessary, variations in the finished condition are reduced, and quality can be improved and maintained.

FIGS. 7 and 8 show modifications of the connection terminal 51 of the second embodiment, respectively. Note that the second
Portions common to the connection terminals 51 of the embodiment are denoted by the same reference numerals, and description thereof will be omitted. The connection terminal 51 of the third embodiment shown in FIG. 7 is provided with a lead 61 for automatic insertion taping.

Further, the lead wire connecting portion of the connection terminal 51 is not limited to the cylindrical shape as in the second and third embodiments, but may be square as in the fourth embodiment shown in FIG. It may be cylindrical or the like. If the cylindrical portion 55, which is the lead wire connecting portion, is formed in a non-cylindrical shape in this way, the cylindrical portion 55 can also serve to prevent the connection terminal 51 from rotating with respect to the printed wiring board 41.

Next, a fifth embodiment of the electric carpet of the present invention will be described with reference to FIGS. Parts corresponding to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. The electric carpet according to the fifth embodiment is obtained by dividing a carpet body 1 having a heater 2 and a separate cover 66 into a plurality of cover members 67, that is, by dividing the cover 66 into a plurality of cover members 67. Although the drawing is divided into four, the number of divisions is not limited thereto. However, 2 to 12 divisions are appropriate. The cover members 67 are detachable from each other by a connecting member 68 such as a magic tape (trade name), a hook, or a fastener attached to their adjacent edge portions. FIG. 9A shows a state in which the cover member 67 is assembled into one cover 66, and FIG. 10 shows a state in which the cover member 67 is mutually divided.

In recent electric carpets, a carpet main body and a cover are separated from each other, but a conventional electric carpet has a single cover. Therefore, when the cover is dirty and washed, it is too large to enter the washing machine, and even if it enters the washing machine, it is too heavy to wash. In addition, when storing in the off-season or the like, it is heavy when the number of sheets is one, and the storing work is particularly difficult for the elderly.

On the other hand, in the electric carpet of the fifth embodiment, since the cover 66 is divided, washing can be performed even with a small washing machine, and no space is required when drying. In addition, only the cover member 67 in the dirty portion can be removed and washing can be easily performed. Therefore, the cover 66 can always be used in a clean state. In addition, individual cover members 67 that can be disassembled can be disassembled for storage.
Is light and easy. This is particularly preferable in today's aging society, and can provide an easy-to-use electric carpet.

FIG. 11 shows a sixth embodiment of the electric carpet of the present invention. The sixth embodiment is a frame surrounding the periphery of a cover 66 comprising a plurality of mutually connected detachable cover members 67. It has a body 69. That is, the plurality of cover members 67 can be integrated or disassembled in the frame 69.

In the fifth and sixth embodiments, the cover 66 is divided in the direction of its spread. However, the cover is divided into a plurality of thin sheet-shaped cover members, and these cover members are stacked to form a magic. It can also be detachably connected by a connecting member such as a tape (trade name), a hook and a fastener.

Further, the present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above-described embodiment, infrared rays are used for transmission from the remote control device 11 to the control unit 31 of the carpet body 1, but ultrasonic waves or the like may be used.
