Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a temperature control device for a cooker, and more particularly to a lead wire mounting structure.

[0002]

[Prior art]

 The temperature control device for a cooking device generally has a structure in which a sliding member for temperature control is slidably supported by a guide member fixed to the cooking device main body. A rack is provided on the sliding member, and the pinion meshed with the rack rotates to move the temperature adjustment rod up and down, and the temperature adjustment rod adjusts the contact gap of the bimetal to set the temperature. I am trying to change.

On the other hand, the electric power of the heating device may be switched between high and low depending on the condition of cooking. In this case, conventionally, the power changeover switch is attached to the cooker main body, but it is conceivable to attach the switch to the temperature adjusting sliding member. When the switch is attached to the sliding part, the operating button of the switch can be incorporated into the operating lever of the sliding member, so that the switch can also be operated with the fingertips of the hand that grips the lever. There is convenience.

[0004]

[Problems to be solved by the device]

 However, when the switch is attached to the sliding member, the lead wire connected to the switch moves due to the sliding of the sliding member, so that the deformation load is partially concentrated and the disconnection easily occurs. For this reason, it is conceivable to increase the number of core wires of the lead wire or cover it with a protective tube, but there was a problem that it was unreliable and costly.

Therefore, an object of the present invention is to provide a highly reliable and low cost lead wire mounting structure by devising a lead wire mounting structure.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention makes a sliding member for temperature control slidably supported by a guide member fixed to the main body of the cooking device, and attaches a switch to the sliding member. In a temperature control device for a cooker, in which an operation button is attached to the front surface of the sliding member, a bundle of lead wires connected to the switch is locked to the sliding member, and the lead wire is connected to the sliding member. Bend the lead wire with enough margin to absorb the amount of movement of the lead wire due to sliding, and make the other end of the bend along the guide wall facing the sliding member, and draw out the lead wire from the guide wall. A holding portion parallel to this is formed at one end on the side, and a lead wire holding gap is provided between the guide wall and the holding portion. The lead wire is pushed into the gap to hold the lead wire, and the lead wire is passed through the gap. The structure pulled out inward of the cooker body It is obtained by the.

[0007]

[Action]

 In the above temperature adjusting device, when the operating lever is gripped and operated leftward or rightward, the sliding member moves leftward or rightward. At this time, one end of the lead wire connected to the switch moves and deforms the bent shape of the lead wire, but the bent shape of the lead wire is maintained even if the sliding member moves in either the left or right direction. Further, one end of the curved portion is kept along the sliding member and the other end is kept in a posture along the guide wall parallel to the sliding member, thereby preventing the partial deformation load from acting on the lead wire.
